pump's water pressure switch. Location of the heat pump
above or below the pool water surface can also affect
operation of the switch.
In general, the pressure switch can be adjusted
to accommodate this effect if the heat pump water
connections are no more than 3,5 m below the pool
water surface or no more than 1,5 m above it. See
instructions for pressure switch adjustment (Section 5.6)
in the heat pump start-up section of this manual for more
information.
If the heat pump is installed outside of this range,
an external flow switch may need to be installed in the
plumbing upstream of the heat pump. Contact your local
Air Energy™ dealer for details.
Be advised that when pool equipment is located
below the pool surface a leak can result in large
scale water loss or flooding. Air Energy™ cannot
be responsible for such water loss or flooding or the
damage caused by either occurrence.

Water Connections at Heat Pump

Shipping plugs have been installed in the water
inlet and outlet ports of the heat pump at the factory.
Before installing any plumbing, remove the shipping
plugs.
Filtered water is plumbed to the inlet, located on
the right side of the heat pump front panel. Heated water
flows through the outlet, located on the left side of the
heat pump front. 50 mm unions are provided.
Plastic piping (PVC Schedule 40) should be
connected to the heat pump. The unions, provided with
the unit, accept 50 mm PVC pipe.

Make sure that fl ow requirements and pool
water turn over rates can be maintained with
the installation of additional heat pumps and
plumbing restrictions.
3.3

Check Valve Installation

The heat pump must be protected from back-
siphoning of water. If there is any chance of back-
siphoning, provide a check valve between the pool and
the filter pump inlet.
When an automatic chemical feeder is installed
in the plumbing, it must be installed downstream of the
heat pump. A check valve must be installed between
the heat pump and the chemical feeder to prevent back-
siphoning of chemically saturated water into the heat
pump where it will damage the components.
3.4

Automatic Flow Control Valve

The inlet/outlet header of the AE-Ti heat pump
comes equipped with an internal automatic flow control
valve. The automatic flow control valve maintains
the proper flow through the heat pump at rates up to
approximately 475 lpm (28
If the filter system flow rate is higher than
approximately 475 lpm (28
bypass valve (see Figure 2 or 3).
NOTE Be advised that if your circulation pump is
over 2 HP or if the total fl ow exceeds 475
lpm, you will have to add an external bypass
valve. Excess water fl ow will damage the heat
exchanger.
