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 100°F-105°F.
5. The resultant heater outlet temperature should be in the range of 120-130°F.
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.
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
100°F-105°F. Turning Valve A in the open direction will raise the heater inlet temperature and closing Valve "A"
will lower the heater inlet temperature.
