Mounting Well into System Return Loop Pipe - Front- Mounted Loop
NOTE: For more detail on piping configurations for large systems, refer to the diagrams on pages 15, 16 & 17.
1. Locate and mark an area on the main system return loop pipe where the well is always exposed to the water circulating back from the pool. See Fig. 20.

2. Shut off water and drain any water from the pipe as necessary.
3. Drill a 23/32" diameter hole (½” NPT) into the pipe as shown in Fig. 21.

4.Using a ½” NPT tap and appropriate handle, thread the tap into the pipe.
5.Apply pipe dope as necessary to male threads of well and insert into threaded hole. Do not over- tighten well.
Fig. 22: Installation with Weld O Lets
NOTE: The drawings and instructions above show only one of several acceptable ways of installing the dry well into main system loop. The use of saddle clamps and “Weld O Lets” (shown in Fig. 22) are acceptable. Follow clamp manufacturer’s instructions.
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 15, 16 & 17)
3.Fire your Raypak pool heater and adjust Bypass Valve "A" to obtain a heater inlet temperature approximately 105°F. Turning Valve A in the open direction will raise the heater inlet temperature and closing Valve "A" will lower the heater inlet temper- ature.
CAUTION: The inlet water temperature must be kept above 105°F. Changes in system flow or valve position may require
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 above 105°F.
5.The resultant heater outlet temperature should be in the range of
