1.4 Plumbing
1.4.a Plumbing Requirements
NOTICE
Failure to heed the following may result in damage to equipment.
l
Do not use glue on the threaded portion of the equipment’s unions. A glued-in-place union will prevent the
equipment from being properly winterized.
l
The heat pump must receive water flow within the specified minimum ranges under worst-case conditions such as
a fouled water filter.
l
Failure to provide clean filtered water to the heat pump can void the product warranty.
l
Water flow exceeding maximum flow rates will negatively affect the total pool filtration performance and may
damage the heat pump. This will not be covered under the equipment warranty.
See " Water Flow Rates " on
page 11.
l
Temperature ports with PVC tees and a test thermometer are also provided in selected models. These ports must
be installed between the unions and the bypass valves. The preferred location of the port is 6" from the heat pump
union.
See " Adjusting Water Flow Using ΔT (Delta-T) " on page 12.
l
A safety-enhancing "Over Temperature Alarm" kit is strongly recommended for all spa applications. See " Over
Temperature Alarm Kit " on page 69.
