Plumbing Sequence
The piping sequence is pool pump – filter – heater – chlorination system(s) – pool.
Rigid PVC piping is recommended and all joints secured with PVC glue. Installation
MUST conform to all local codes. Make sure water-flow is correct as indicated on back
of heater. Again, try to keep piping away from areas that may be tripped over or
stepped on when operating heater or servicing. Try to keep elbows and piping to a
minimum to avoid excessive pressure drop. We use a full-flow heat exchanger so no
external bypass is needed up to 60 GPM.
