1.4.a Plumbing Requirements
NOTICE
Do not use glue on the threaded portion of the equipment's unions. A glued-in-place union will prevent the
l
equipment from being properly winterized.
The heat pump must receive water flow within the specified minimum ranges under worst-case conditions such as
l
a fouled water filter.
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
l
damage the heat pump. This will not be covered under the equipment warranty. See "Water Flow Rates" on
page 14.
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
l
applications are highly problematic and require additional maintenance.
If a saltwater source is unavoidable, install an external plate heat exchanger to protect the heat pump from
l
fouling. Please note – Saltwater wells do not require an external plate heat exchanger.
A safety-enhancing "Over Temperature Alarm" kit is strongly recommended for all spa applications. See "Over
l
Temperature Alarm Kit" on page 77.
Failure to heed the following may result in damage to equipment.
