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 14.
l
Using open saltwater applications as the heat pumps source water is not recommended.
l
Saltwater can promote the growth of crustaceans, which can clog a heat pump’s heat exchanger. These types of
applications are highly problematic and require additional maintenance.
l
If a saltwater source is unavoidable, install an external plate heat exchanger to protect the heat pump from
fouling. Please note – Saltwater wells do not require an external plate heat exchanger.
l
A safety-enhancing "Over Temperature Alarm" kit is strongly recommended for all spa applications. See " Over
Temperature Alarm Kit " on page 77.
