To adjust the temperature:
1.Both isolation valves must be fully open.
2.Adjust Bypass Valve "A" 1/2 open and Balancing Valve "B" fully open. (See piping configuration page 11)
3.Fire your Raypak pool heater and adjust Bypass Valve "A" to obtain a heater inlet temperature approximately
4.If the heater inlet temperature remains less than 100°F and Valve "A" is fully open, leave Valve "A" fully open and throttle Valve "B" until the heater inlet temperature rises to within the range of
5.The resultant heater outlet temperature should be in the range of
6.As the pool temperature rises to the desired temperature 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 100°F without heater damage but operating at less than 100°F inlet can cause damage from condensation.
Note: Consult factory if target temperatures cannot be achieved.
