11 Wa ter Pressur e Switch On Models 926-1223 built with a Unitherm Governor (UG), a water pressure switch is provided in the heater to shut down the gas valves in the event the water sup- ply to the heater is interrupted. It is very important to v erify that the switch electrically opens and shuts off the gas valve when water flow to the heater is[...]

12 Raypak recommends the installation of an air bleed vent at a suitable location (usually the highest point in the plumbing) to remove air from the piping system. These units should be available at your local whole- sale supplier . Raypak does not provide this item. Models 1287 through 4001 are equipped with an external pump and bypass arrangement[...]

Fire your Raypak pool heater and adjust Bypass V alve "A" to obtain a heater inlet temperature approximately 105°F . T[...]

15 6. As the pool temperature rises to the desired tem- perature as controlled by the Pool aquastat, small adjustments to valves "A" and "B" will be required for optimum performance. Heater temperatures should be checked regularly to prevent heater condensation. The heater inlet temperature can be higher than 105°F without heat[...]

25 Tw o-Speed Pumps In some cases, the flow on the low speed is insufficient to operate the heater . This is apparent when the pres- sure switch cannot be further adjusted or if the heater makes banging noises. In these cases, the pump must be run at high speed when heating the water . Pilot Safety The heater employs a pilot safety which closes the[...]
