When connecting 3-phase units, make sure
that the phases are in correct order or the
machine won’t start. If the machine won’t
start at the first setup, please swap two
phases around and the machine will start.

Distance to the pool
The pool heat pump is normally installed in connection to
the pool’s purification system to minimise pipe routing. If the
pipes are insulated heat loses will be minimal provided that
the overall pipe length is less than 30 metres (pool water in
and pool water return). An approximate estimation of the
heat loses over an overall pipe length of 30 metres is 0.6
kW per hour for each 5 degrees of temperature difference
between the pool water and the air surrounding the pipes.
This is equivalent to an increased running time for the heat
pump of 3-5 %.
Leading off condensation water
Outdoor air is cooled in the evaporator by approximately
5-10 degrees. The water vapour then condenses on the
evaporator coil fins. If the air humidity is high this can result
in many litres of water per hour. To counter this, there are
several drainage holes in the base plate to lead off the water.
It is important to consider the position of the unit so that the
condense water can be led off correctly.
Pipe connections
The pool heat pump is connected to the pool’s circulation
system with the help of the supplied 50 mm union couplings.
Screw connections to the heat exchanger must be tightened
by hand.
A bypass coupling must be fitted to adjust the right partial
flow to the pool heat pump, and to simplify service.
Bypass coupling
We recommend that a bypass coupling is fitted to all
installations in order to adjust the right partial flow to the
pool heat pump. The right partial flow results in balanced
operation and reduced wear on the heat pump’s most
expensive section, the heat exchanger.
Adjusting the bypass
Correct adjust of the bypass can be done in different ways.
One of the easiest ways can be summarized as follows:
Open all the valves
1.
Check parameter A and b, see section 3.
2.
If the difference is above 2 degrees, gradually close the
3.
bypass valve until the difference is between 1-2 degrees
If the display shows EE03 this means that the flow switch in
the system receives insufficient water, so the bypass valve
must be closed more to increase the flow through the pool
heat pump.
First open all the valves to simplify adjustment of the bypass.
Electrical installation
The electrical connection is made to the pool heat pump’s
junction box located behind the front panel. A working
switch (with or without a fuse) must be connected and be
positioned fully visible next to the unit. The working switch
protects against unintentional starting, for example, when
servicing the unit. Even if the heat exchanger is electrical
isolated from the remainder of the system and separates the
pool water from the electricity, the unit must be connected
to earth to provide satisfactory short-circuit protection.
There is an additional connection on the terminal block, 1
and 2. This connection can be used if you wish to connect a
separate circulation pump to the pool heat pump.
See the wiring diagram in section 5 for more detailed
information about the electrical connection.
Starting up the unit
In order to heat the pool or spa water, the pool’s circulation
pump must start and water needs to circulate through the
heat exchanger. The following procedure should be followed
when starting the pool heat pump for the first time:
Start the pool’s circulation pump. Check for any leakage
1.
and that there is a flow to and from the pool.
Switch on the supply voltage and check the current
2.
running settings.
Installation
Do not confuse condense water
for water leakage.
