How to Read a Raypak Serial Number
RayPak Heaters - Further Reading
Raypak Heaters
Raypak Model Number History tin assist empathise the various current and previous Raypak production lines and model numbers.
Raypak has a few production lines of heaters. Raypak residential pool and spa gas heaters include above footing heater models; in-footing heater models from 200K to 400K BTU; and low NOX versions of the in-ground heatrs from 200K to 400K BTU.[1]
Raypak as well has a product line of residential pool and spa heat pumps with v models from 48K BTUs to 140K BTUs.[2] The college BTU heat pumps are bachelor in a model with heating and cooling.
The Raypak Professional series heat pump pool heaters, from 140K BTUs to 170K BTUs, are designed specifically for commercial backdrop such equally apartments, condos, hotels, motels, schools, parks, community and high-end individual pools.[iii] It'south likewise advisable in tough littoral atmospheric condition conditions where table salt air challenges durability.
Raypak also has a wide range of commercial gas pool heaters with BTUs up to 2,340,000 BTUs.[4]
Rapak is a Rheem visitor and most HVAC companies know their way around the units and tin get parts. Y'all are not locked into installation and service through pool store channels. Raypak has a skilful warranty for heaters purchased separately and installed past a professional person contractor, not necessary a puddle company.
Raypak heaters accept a traditional burner tube geometry like a BBQ or hot water heater. Gas is injected into a manifold of burner tubes with the heat driving the period of frazzle out the stack. This design is susceptible to wind and atmospheric issues causing flame ringlet out problems and dirty combustion tubes.[5]
Digital Model Gas Heaters
Since 2004 Raypak has manufactured the Digital models MODELS 206A, 266A, 266, 336A, 399 and 406A; and since September 2011 the Low NOx HEATER POOL MODELS 207A, 266L, 267A, 337A, 399L and 407A.
Low NOx Heater Model
Low NOx heaters usually take somewhat higher efficiencies and exhibit much lower NOx emissions.
They were developed to satisfy low NOx emissions requirements as commencement imposed past the Due south Coast Air Quality Management District in California. Your area might crave a low NOx heater. Y'all should consider a depression NOx heater in whatsoever case.
Raypak Model Numbers
- Designation for a Digital heater using propane gas is "EP"; a Digital heater using natural gas is "EN".
- Designation for a Millivolt heater using propane gas is "MP"; a Millivolt heater using natural gas is "MN".
- Prefix "P" is for plastic (polymer) headers.
- Suffix "Ten" is for cupro-nickel tubing; "C" is for copper tubing.
- Instance: P-M406A-EN-X = Plastic headers, 406 model size, digital, natural gas, cupro-nickel.
Raypak Serial Numbers
Before 1995, it was month (first 2 digits) and and so year (digits 3 and 4).
Kickoff in 1995, they changed to year and month. The outset 2 are the year and the next 2 are the month.
Serial number 1604304448 was made in Apr 2016.
Cupro-nickel Heat Exchangers
The cupro-nickel heat exchanger is 25% NICKEL AND 75% COPPER (denoted past an "X" at the end of the model number.) The other unit is 100% copper (denoted past a "C" at the cease of the model number.) The copper heat exchanger is the virtually efficient material for heat transfer, so the cupro-nickel is derated.[6]
The purpose of the cupro-nickel is to give additional protection to the rut exchanger that can be attacked with poor water chemistry. That is the advantage, only information technology also has less ability to transfer oestrus.
The input BTUH accounts for the heat exchanger material, and the heater efficiency is 82%.
How to Locate the Raypak Heater Model and Series Number
The heater's model and serial numbers are located on the rating plate found on the inside of the unit of measurement. To locate the rating plate, commencement loosen the door spiral. Remove the door(s), pull upward and out. The rating plate will be either a gilded or silver colour with the Raypak logo. The series number will accept 10 digits. The date code is found in the first 4 digits of the serial number, for example, a unit made in Apr of 2001 volition accept the first four digits read every bit 0104.
Propane Heaters
The board on the propane heater, depending on the age, volition have a tab that has been broken off.
Propane is heavier than NG when its in gas form and information technology likes to sink to the floor and pool, making for some lively outcomes if it happens to pool in the right identify. The designers at Raypak found a way around this. When the tab is cleaved off, the system will only effort to light one time before information technology locks out, instead of the three tries for NG.[seven]
If you convert a propane heater to NG by installing the NG orifices and NG gas valve regulator you will demand to disconnect power from the heater to reset it and then try once again if information technology does non light.

Heater Hits Max Temperature earlier Actual Temperature
When automation is controlling the heater the automation temperature and the Raypak heater temperature can exist different and the heater can hit its maximum temperature while the water is non yet to that temperature.[eight]
The default maximum temperature for the puddle and spa tin can be raised. Note that raising the max temperature may cause Loftier Limit two Errors.
See page 28 of the Raypak INSTALLATION AND OPERATION Manual
Spa Max Temp – Spa Setpoint Maximum Adjustment
Refer to step 1 on page 28 to access the program screen. Press the Style button until SPA MAX TEMP appears on the digital brandish. Using the UP and DOWN buttons will change the Maximum Temperature Setting to your desired value. The control can exist set for a maximum of 107°F (42°C).
Pool Max Temp – Pool Setpoint Maximum Adjustment
Refer to step i on page 28 to access into the program screen. Press the Mode button until Pool MAX TEMP appears on the digital display. Using the UP and Down buttons will change the Maximum Temperature Setting to your desired value. The control tin can exist set up for a maximum of 107°F (42°C).
High Limit 2 Mistake
Things yous tin try...
- supercede both high limit sensors and add thermal paste
- replace unitherm governor
- replace internal featherbed
- add together a heat shield
Some folks accept added a heat shield above the HLS sensors.[9] This thread describes how the loftier limit error was fixed by insulating the header around the sensors.
Internal Bypass
This is what a rusted internal bypass looks similar that can crusade HLS errors.[10]
Unitherm Governor
This is what a corroded unitherm governor looks like:
Service Card and Fault History
To access the Service Menu and fault history, press the Fashion and Upwards buttons simultaneously for 3 to 5 seconds. The heater will continue to operate commonly while in the Service Menu. The kickoff screen displayed is the Flame Strength indicator, which indicates the pilot flame current using a bar graph and numerical display. A indicate of less than four indicates a weak flame signal and may require service. Refer to Department v Troubleshooting for possible causes and corrections.[11]
Printing the Downward push. The Supply Voltage screen indicates the voltage supplied to the control lath. Normal readings range from 24 to 29 volts.
Press the DOWN button. The Run Time indicates the total hours of operation for the pool heater, as measured by the amount of time that the main gas valve has been powered. The Cycle count indicates the number of on/off cycles of the heater, as measured by the number of times the airplane pilot valve has been powered.
Printing the DOWN button. The Fault History can display upwardly to ten faults in retention. The order of the faults begins with "Fault Final," which is the most recent fault, and gain through ten near recent messages in chronological social club. The second line of the display shows the error message. If at that place are no faults in the history buffer, the second line reads "All Faults Clear."
Altitude Adjustments
Air is thinner and less dense as the altitude increases. A natural gas or propane heater needs an optimum mixture of air and gas. If the air/gas mixture is incorrect you lot will have an orange xanthous flame instead of a good bluish flame.
At higher latitudes the gas needs to be adapted for the proper air/gas mixture.[12]
- The Raypak Standard Digital is skillful to 2,000 feet.
- The Raypak Digital depression NOx is good to 5,000 anxiety.
Atmospheric heaters: Rated inputs are suitable for up to 2,000 feet elevation. For elevations higher up 2000 feet, reduce gas input iv% for each ane,000 feet above sea level, every bit loftier elevation reduces combustion performance.
Lo NOx heaters: Rated inputs are suitable for up to 5,000 anxiety pinnacle. For elevations above 5000 feet, consult the factory.
Raypak LP heater loftier limit fault
This thread describes how the high limit fault was fixed by insulating the header around the sensors.
Rollout Switch Failures
If loftier winds are blowing out the rollout switch consider installing the Raypak Outdoor (Loftier Air current) Stack for Gas Fired Heaters.
The stack hood can help alleviate problems caused by excessive winds interfering with the menstruation of flue gas considering the structure of the stack hood allows for dilution air to the flue gas which acts like to a vacuum breaker on a h2o system by reducing/eliminating backflow.[xiii]
Y'all tin observe a YouTube video on the installation.
Millivolt Trouble Shooting
Check for 500 mv dc coming from the pilot generator. Red and white wires. Red pilot generator wire goes to the TP terminal. White pilot generator wire goes to the TP/TH terminal.[14]
If that'south good, check for 500 mv dc from the TP concluding to the TH terminal with the violet wire.
If that'due south non good, you have something open up on the limit string.
The limit string is a series of on/off switches that all accept to be on for the voltage to go from the TH/TP final to the TH concluding.
The carmine wire connected to the TH/TP goes to the roll out switch, you lot should measure 500 mv dc betwixt the TP terminal and the other side of the scroll out switch. The red wire leaving the roll out switch should go to the h2o pressure switch. You should mensurate 500 mv dc to the orange wire leaving the pressure switch.
The orange wire leaving the pressure switch should go to the offset high limit. You should measure 500 mv to the out terminal of the commencement high limit switch.
From the first high limit switch, there should be a blackness wire to the second high limit switch. You should measure out 500 mv to the out terminal of the 2nd high limit switch.
Leaving the 2nd high limit switch should be a black wire going to the thermostat. You should measure 500 mv on the out terminal of the thermostat.
Leaving the thermostat, there should be a yellow wire going to the on/off switch. You should mensurate 500 mv on the out terminal of the on/off switch.
Leaving the on/off switch should exist a violet wire going to the TP terminal.
So, basically, the voltage needs to get through the entire string in series to power the gas valve.
Y'all can remove the cherry wire from the Th/TP concluding and remove the violet wire from the Thursday final and check the resistance of the entire limit cord.
The entire limit string should be airtight and evidence low ohms.
If open, you can go in serial every bit described above checking to run across which limit is open.
If loftier ohms, a limit might exist bad or a connector might be bad.
Note: TP means thermopile. TH ways thermostat.
The gas valve has two solenoids. It has a pilot valve solenoid and a main gas valve solenoid.
The pilot valve solenoid is powered by the TP and TH/TP terminals. The resistance of the airplane pilot valve solenoid should be well-nigh 9 to 11 ohms.
The main gas valve solenoid is powered past the TP and TH terminals. The resistance of the main gas valve solenoid should be about 1.v to 1.seven ohms.
RP2100 Model Gas Heaters
The RP2100 models of gas heater were manufactured from 1998-2004 and were replaced by the current Digital model. Models are R185A, R265A, R335A, R405A (ATMOSPHERIC, Depression NOx)
R185A, R265A, R335A, R405A (ATMOSPHERIC, Low NOx) Replacement Parts
Raypak Estrus Pumps
Raypak Heat Pump High Pressure Trip Lockout
The high pressure refers to the refrigerant force per unit area from the compressor, not the pool organization pressure. The refrigerant pressure might be too high or you might take a low flow problem.[fifteen]
There have been reports of a few newly installed Rut Pumps where Raypak needed to send out service nether warranty to adjust the high force per unit area switch.
Loftier Pressure Switch Lockout
If the loftier pressure switch opens, the control de-energizes the compressor output and the fan continues to run for fifteen minutes subsequently the HPS opened and the brandish will show "Hi Press Trip".
If the high pressure switch trips 7 times in a single bicycle, the display volition bear witness "Hi Press Lockout" and the unit will exist locked out of operation for four hours.
The unit will automatically reset after iv hours or the lockout tin exist manually reset past pressing the Menu button or cycling the power.
The high pressure switch must close for iii seconds for the control to recognize it as closed.
Raypak Estrus Pump Water Pressure Switch Adjustment-
The Raypak HP Installation Transmission says "If the location of the HPPH is below the water line of the pool, the H2o Pressure Switch (WPS) or Water Menstruation Switch (WFS) might need to be adjusted or an external WFS might exist needed."
If your HP tries to turn on when your pump is off then the H2o Force per unit area Switch requires adjustment or you need a Flow Switch. This tin can happen when the pool h2o level is more than then a few feet to a higher place or below the HP. This volition be the example when the HP is used with an Above Ground Pool.[sixteen]
The H2o Pressure Switch has a locking feature on the bottom. You accomplish under the switch and movement a piece of plastic to unlock it, then rotate the dial and test until it works correctly. Once yous have the best setting, lock the switch and supervene upon the encompass. Don't accidentally remove the sensor from the tube when making the aligning.
Raypak 5450/6450/8450 Oestrus Pumps No Longer Have the Internal Automatic Bypass
At that place is an April, 2020, report that the newest Raypak 5450 / 6450 / 8450 estrus pumps no longer accept the internal automated bypass. It has been removed, though their website, data sheets, etc. still annunciate this characteristic. The fellow member has a new 5450 and the water menstruation is terrible - not plenty to drive the Polaris cleaner.[17]
