Product Changes

Gas Valve Change
131 Model pool heaters manufactured before the 27/3/07 utilise a White Rogers 36E06-
301 gas valve, models manufactured after the 27/3/07 utilise a White Rogers 36G22-216
gas valve. The 36E06-301 gas valve is no longer available however the 36G22-216 gas
valve is a direct replacement. For more information refer to „Gas Valve‟ on page 52.
Change to Black Control Board
Raypak pool and spa heaters manufactured from July 2005 to the 31/10/2006 were fitted
with a controller which has a grey decal on the control panel. Models manufactured from
November 2006 onwards are fitted with a revised control board which incorporates
additional software functions, fault codes and a revised wiring arrangement. The revised
control board can be identified by a control panel with a black decal.
This Service Manual including fault finding charts covers both types of control panels.
Both control boards operate and are programmed in a similar fashion however black
control boards have additional fault codes and features. It should be noted that the wiring
arrangement also differs depending upon whether a black or grey board is fitted. Refer to
page 9 for grey board wiring diagram and pages 10 & 11 for black board wiring diagrams.
Black control board
Addition of Reset Button Safety Lock Out Circuit & Weather Shielding.
All Raypak pool and spa heaters manufactured after 14/04/2008 have been fitted with an
additional safety feature and weather shielding. The additional safety feature incorporates
a red reset button located on the front control panel and two relays located in the control
box (relay 1 and relay 2).
The safety lock out circuit prevents the heater from operating if the 45ºC inlet high limit
trips (open circuits) due to an over temperature condition.
If the 45ºC inlet high limit trips (open circuits), relays 1 and 2 open and „lock out‟ the pool
heater control circuit preventing operation until the 45ºC inlet high limit closes and the pool
heater is manually reset by pressing and releasing the red reset button. For more
information refer to „Sequence of Operation‟ on page 12 and wiring diagrams on pages 9-
11.
Pool and spa heaters manufactured prior to the 14/04/2008 did not have the safety lock
out circuit or additional weather shielding fitted. A recall campaign to rework all Raypak
pool and spa heaters in the field was commenced in March 2008.
Any Raypak pool or spa heater that does not have a red reset button located
on the control or side panel does not have a safety lock out circuit or
additional weather shielding and MUST be reworked. Contact Rheem Service
for more information.
