Installation

Plumbing Connections

The image below shows the standard plumbing layout with a single UltraTemp Heat Pump unit.
TM
Arrangement of pool system components (other than the standard plumbing image below), can
affect the operation of the heat pump.
Note: Be advised that when pool equipment is located below the pool surface a leak can result in
large-scale water loss or flooding. Pentair is not responsible for such water loss or flooding or
damage.
The heat pump should be connected to a filtration circuit through a by-pass which consists of 3
valves. It is imperative that the by-pass is placed after the pump and the filter. These valves allow
to regulate the water flow which passes through the heat pump and to isolate the heat pump com-
pletely for any maintenance work, without cutting the filtration flow.
If your installation is equipped with water treatment devices (chlorine, bromine feeder, salt water
chlorine generator, others) the by-pass must be installed before the water treatment devices, with
a non-return check valve between the by-pass and water treatment devices.
Water inlet and outlet are designed to be connected to rigid pressure PVC tube (for swimming pool)
40mm, directly glued to the union connectors provided.
Water pipes must be fixed on the floor or the walls, so the heat pump will not support the weight of
the water inside the plumbing.
