Water IN & OUT Connections

For proper operation and maximum efficiency, piping coming from the pump and filter MUST be connected to the

"IN" port of the heater.  Likewise, connect piping returning to the pool/spa to the "OUT"  port of the heater.  See

drawing below.

WARNING!

Failure to heed the following may result in permanent injury

electrical enclosure or as close as possible to the heater.  Always satisfy applicable codes and

standards.

u

All AquaCal heat pumps are designed for copper conductors, only. In sizing power wiring, be

especially aware of up-sizing requirements required due to wiring distances.  Always satisfy

             applicable codes and standards.

u

Multiple heaters installed at same site generally require special sequencing controls (AquaCal part

#ASC-(number of heaters)); if yours is a multi-heater installation, contact AquaCal Technical Support

for assistance (800-786-7751).

u

Electrical installation should be by licensed electrician only.

u
