Distance to the pool
The pool heat pump is normally installed in connection to
the pool’s purification system to minimise pipe routing.
Leading off condensation water
Outdoor air is cooled in the evaporator by approximately
5–10 °C. 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 connection
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 connection should be fitted for easier setting of
the correct partial flow to the pool heat pump, as well as to
facilitate servicing.
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.
Adjusting the bypass
Adjusting the bypass can be achieved in a number of ways.
One of the easiest ways can be summarized as follows:
1. Before adjusting the bypass, first check that the pool’s
filter system has been cleaned for maximum flow.
2. Open all the valves
3. Check the inlet and outlet temperatures, see section 3.
4. If the difference is above 2 degrees, gradually close the
bypass valve until the difference is between 1 and 2
degrees.
If the display shows “E03”, this means that the flow through
the pool heat pump is too low. The bypass valve must then
be closed further in order 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 service hatch. A safety
switch must be connected and be in a fully visible position
next to the unit. The safety switch protects against
unintentional start-up, for example, when servicing the
unit. Even if the heat exchanger is electrically 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.
For pool heat pumps in three-phase design, the phases
must be connected in the right order, otherwise the power
supply to the control system will be interrupted by the phase
sequence protection. When the phases are connected in
the correct order, this is indicated in the phase sequence
protection by the green and yellow LEDs being active. A
green LED indicates that the correct voltage is present and a
yellow LED indicates the correct phase sequence.
There is an additional connection on the terminal block,
1 and 2. This connection can be used if you prefer 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.
When connecting three phase design models,
the phases need to be in the correct order,
otherwise the LED display will not light and
the pool heat pump will not start.
