Indoor Installations
Every indoor installation is unique, therefore, there are no specific guidelines for this type of installation. For
assistance, please contact our Engineering or Technical department and they will assist you with your specific
needs.
Plumbing
All Aqua Cal Heat Pumps are equipped with either 2” MPT or FPT PVC fittings for the installer to connect to. No
additional valving or bypass is necessary unless flow rates through the heat pump exceed 70 gallons per minute.
Most residential pools and spas will not require a bypass unless a pump of 2 hp or larger is used.
When threading fittings into the 2” FPT connections on the heat pump, be sure to use a thread sealing compound
suitable for PVC. Be careful not to over tighten fittings.
