4. Preparing the heat pump for use
4.1 Typical set-up
The factory provides the heat pump, Condens  ux, connection kit and winter cover. Other parts, including
a contingent by-pass must be provided by the user or installer. The heat pump should be located maximum
7,5m(1) away from the swimming pool. The longer the distance from the pool, the greater the heat loss from the
piping.
4.2 Installation of a check valve
When using automatic chlorine and pH dosage systems, it is of uttermost importance to protect
the heat pump from high concentrations of these chemicals that could corrode the heat exchanger
after long term use. Therefore, such systems should add the chemicals in the conduits located
DOWNSTREAM of the heat pump and it is recommended to install a check-valve in order to
prevent back ow when there is no water circulation.
Damage to the heat pump caused by disregarding any of these recommendations will invalidate
the warranty.

Put the heat pump on a  at, solid base. Tilting the heat pump for max 3° is allowed.
Install silent blocks in order to avoid vibrations and noise.
All feeding of water treatment to the pool water has to be done downstream of the heat pump(2).
It is normal for condens water to come out of the heat pump. This is not a leak or fault with the unit. If the
humidity is very high, the condens water could be a number of liters a day. Please  nd more information
about condensation in section 5.2.
Always keep the heat pump in upright position. If the unit has been tilted, then wait 24h before starting the
heat pump.

4.3 Installation of the tubing
The factory provides the water connecting kit. Other parts, including a contingent by-pass are to be provided
by the user or installer. The heat pump should be located maximum 7,5m away from the swimming pool. The
longer the distance from the pool, the greater the heat loss from the piping.
4.4 Electrical wiring
Check if the electrical mains voltage corresponds with the operating voltage of the heat pump
prior to hooking up the unit. It is recommended to use a separate fuse as well as adequate wiring.
Connect the electrical wires using the following steps
Step 1: Remove display. Step 2: Unscrew blue front housing.
Step 3: Snap off blue front housing Step 4: Remove  ow sensor
Step 5: Remove transparent cover.
Step 6: Insert the electrical cable at the bottom of the heat pump(1). Make electrical connection with heat pump’s
terminal block(2).

Please note the outlet  ow is equiped with a  ow sensor. Therefore the heat pump will only start when the
water  ow is running in correct direction.
Although the heat pump is electrically isolated from the rest of the pool equipment, this only prevents the
passage of electricity to or from the pool water. Grounding the unit is still required to protect yourself from
short circuits inside the unit. Provide an adequate ground connection.
Water connection from heat pump:
Typical water pipe from heat pump to
water treatment system.
Water connection to heat pump:
Typical water pipe from  lter system
to heat pump.
Please turn off  lter pump. Flow must be stopped before disconnecting  ow sensor. Drain the water out of

5. Be aware of
5.1 Heat loss
The pool heat pump is installed within 7.5 meters of the pool. The longer the distance from the
pool, the greater the heat loss from the tubing. Therefore, the heat loss is minimal for runs of up
to 7,5 meters(7,5 meters to and from the pump = 15 meters total), unless the ground is wet or the
water table is high. A very rough estimate of heat loss per 15 meters is 0.3 kW-hour,(1000BTU) for
every 5°C difference in temperature between the pool water and the ground surrounding the pipe,
which translates to about 3% to 5% increase in run time.
5.2 Condensation
As the heat pump cools down the air about 10°C, water may condense on the  ns of the evapora-
tor. If the relative humidity is very high, this could be as much as several liters an hour. The water
will run down the  ns into the base pan and drain out through the hole at the bottom of the heat
pump.
An extra  tting, Condens Flux, is attached and can be mounted upon the bottom housing. This
 tting is designed to accept 20mm clear vinyl tubing which can be pushed on by hand and run to a
suitable drain. It is easy to mistake the condensation for a water leak inside the unit.
TIP:
A quick way to verify that the water is condensation is to shut off the unit and keep the pool pump
running. If the water stops running out of the base pan, it is condensation. AN EVEN QUICKER
WAY IS TO TEST THE DRAIN WATER FOR CHLORINE - if there is no chlorine present, then it’s
condensation.
Step 1: Connect Condens  ux upon bottom housing Step 2: Connect 20mm clear vinyl tube
Several days will be needed to bring the temperature of the swimming pool water to its desired water
temperature, depending the initial water temperature, ambient and pool volume.
5.3 Unobstructed space
A free area around the heat pump has to be kept clear from any object to get fresh air across the
evaporator. Do not obstruct the fan.
5.4 Time delay of compressor
The heat pump is equipped with a 3 minute built-in solid state restart delay once the compressor
is turned off and a 1 minute buit-in solid state compressor running time. Both to protect control
circuit components, to eliminate restart cycling and contactor chatter. This time delay will auto-
matically restart the unit approximately 3 minutes after each control circuit interruption or after a
compressor running period of 1 minute. Even a brief power interruption will activate the solid state
3 minute restart delay and prevent the unit from starting until the 3 minute countdown is complet-
ed. Alarms or errors during time delay have no in uence. Power interruptions during the delay
period will cause a restart of time delay.
