Installation
Installation items
The factory only provides the heat pump unit; the other items that are mentioned in the
illustration are to be provided by the user or installer.
Attention!
○All feeding of chemicals to the pool water has to be done downstream of the heat pump.
○Install a bypass when the flow of the pool pump is more than 20% above the rated flow
of the heat exchanger of the heat pump.
○Install the heat pump on a solid foundation and use damping rubbers to eliminate
vibrations and noise.
○Always keep the unit straight up. If the unit has been tilted or put on his side, allow
24h before starting the unit.
Location
The unit may be installed virtually anywhere outdoors . For indoor pools please consult
your supplier.
DO NOT put the unit in an enclosed area with a limited air volume where the unit
discharge air will bere-circulated.
DO NOT put the unit next to shrubs, which can block the air inlet. Such locations deny
a continuous source of fresh air, which reduces its efficiency and may prevent adequate
heat delivery.
The picture below give the minimum required distances from each side of the heat
pump.
Install the heat pump where you have the best access
to warm air during the swimming season

7
Distance
Install the heat pump as close to the swimming pool as possible to minimize the loss of
heat through the piping. Put it on a solid base and place the rubber blocks under the heat
pump to eliminate vibrations.
Normally, the pool heat pump is installed within a 7,5 meter radius of the pool. The
minimal distance to the pool is 3,5m.
The greater the distance from the pool, the greater the heat loss from the piping. Since the
piping is buried for the most part, heat loss is minimal for distances of up to 30 meters (15
meters to and from the pump= 30 meters total),unless the soil is wet or the water level is
high. Heat loss per 30 meters could roughly be estimated at 0.6kw-hour (2000 BTU) for
every 5 temperature difference between the pool water and the soil surrounding the pipe
which translates to an operation time increase of 3-5%.
We advise the installation of a proper 50mm tube insulation on aboveground tubes.
Installation of the 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. 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 backflow when there is no water circulation. Damage to the heat pump caused by
disregarding any of these recommendations will invalidate the warranty.

8
Configuration
Note: the above piping connection is only an example for demonstration.
Installation of the bypass
With the bypass set correctly, your heat pump will deliver its best performance. The
bypass has to be built as shown below:
○ Install the bypass with all 3 valves entirely open
○ Slightly close valve 1
○ Close valve 3 about half way to adjust the refrigerant pressure

9
Electrical wiring
For the electrical connection of the heat pump use the connectors L, N and grounding.
Verify the local power supply and the operating voltage of the heat pump. It is
recommended to use a separate circuit breaker (slow type –D curve) for the heat pump
together with the proper wiring characteristics. The current to the heat pump should only
be applied when the filter pump is running. For example, a relay controlled by the filter pump
could be used to activate the current to the heat pump. Connect the electrical supply to the
junction box inside the heat pump. All heat pumps require a single-phase connection.
Grounding the heat pump is required to protect you against electrical shocks caused by an
eventual short circuit inside the heat pump.
The heat pump is equipped with a flow for water flow detection. If the water flow to the
heat pump stops or is insufficient, the heat pump will also stop.
The heat pump is not equipped with a plug. The heat pump need to be connected straight
into the electrical casing circuit breaker.
Values in this table are only guidelines. Please check your local regulations.

Start-up procedure
After the installation is completed, you should follow these steps.
1. Set the by-pass valve 1 entirely open. Turn on your filter pump. Check for water leaks
and verify flow to and from the pool.
2. Turn on the electrical power supply to the unit and turn the unit ON with the switch.
Slightly close valve 1 until the heat pump starts.
3. After running a few minutes, check if the air leaving the side of the unit is cooler.
4. Check the performance of the flow switch as follows: with the unit running, turn the
filter pump off. The unit should also switch off automatically. If not, the flow switch
must be readjusted.
5. Allow the unit and pool pump to run 24 hours per day until desired pool water
temperature is reached. When the set temperature is reached, the unit just shuts off.
The unit will now automatically restart (as long as your pool pump is running) when
the pool temperature drops more than 1° C below set temperature. It can take several
days for the water to reach the desired temperature. Covering the pool can drastically
reduce this period.
Water flow switch - the unit is equipped with a flow switch that is switched on when
enough water has flowed through the unit and that is switched off when the water flow
becomes too low. e g. when the filter pump is switched of.
Time Delay - the unit is equipped with a built-in 3-minute start delay to protect electrical
components and contacts. After this time delay, the unit will automatically be restarted.
Even a brief interruption of the power supply will activate the start delay and prevent the
unit from starting immediately. Additional interruptions of the power supply during the
delay period will have no effect on the 3-minute countdown.
Daily use of the heat pump
The heat pump can be switched on an off via the on-off switch. The heat pump can also be
connected to the same power grid as your filtration pump, so that the heat pump is
switched on automatically as soon as the filtration pump is switched on.
Under 8°C, a low temperature alarm will stop the heat pump functioning to prevent
freezing of the heat pump.
Under normal conditions of flow, the heat pump will heat the pool water by 0.25-1 deg per
pass.
Condensation
Since the heat pump cools down the air about 8 - 12 °C, water may condense on the fins of
the evaporator. If the relative humidity is very high, this could be as much as several liters
an hour. Sometimes this condensation water is wrongly considered as a water leak of the
swimming pool water. If water, collected from the heat pump, contains chlorine, it is
swimming water.

11
Guidelines
Water chemistry
Special attention should be paid to the chemical balance of the pool water. The values
should always stay within the following limits:
Min
Max
pH
7,0
7,4
Free chlorine (mg/l)
0,5
1,2
TAC (mg/l)
80
120
Salt (g/l)

Attention!
○Failure to keep the swimming pool water between above limits will invalidate the
warranty
○When the concentration of one or more products mentioned above becomes too
high, irrevocable damage to your heat pump may occur. Make sure that you
always install water treatment equipment after the heat pump.
○When an automatic chemical feeder is installed in the tubing, 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.
Winter-ready
Attention! Failure to winterize could cause damage to the heat pump and will void warranty.
In areas where freezing temperatures occur, you should protect your pump, filter and heat
pump from the elements. Perform the following steps to completely drain the heat pump.
1. Turn off the electrical power to the heat pump at the main breaker panel.
2. Shut off the water supply to the heat pump: close valves 2 and 3 on the by-pass completely.
3. Disconnect the water inlet and outlet and let the water drain from the heat pump. Blow
all water out of the heat pump.
4. Re-connect the water inlet and outlet loosely to prevent debris entering the connections.

12
Spring start-up
If your heat pump has been winterized, perform the following steps when starting the
system in the spring:
1. Inspect the system for any debris or structural problems.
2. Connect the water inlet and outlet unions firmly.
3. Turn on the filter pump to supply water to the heat pump. Adjust the by-pass to allow
water flow through the heat pump.
4. Turn on the electrical power to the heat pump at the main breaker panel.
Owner inspection
The QBIC heat pumps are designed and constructed to provide long performance life when
installed and operated properly under normal conditions. Periodic inspections are
important to keep your heat pump running safely and efficiently through the years. The
following basic guidelines are suggested for your inspection:
1. Make sure the front of the unit is accessible for future service.
2. Keep the surrounding areas of the heat pump clear of all debris.
3. Keep all plants and shrubs trimmed and away from the heat pump.
4. Keep lawn sprinkler heads from spraying on the heat pump to prevent corrosion and
damage. Use a deflector if needed.
5. If the unit is installed under a very sharp roof pitch or under a roof without a gutter, a
gutter or diverter should be fitted to prevent excessive water from pouring down onto
the unit.
6. Do not use the heat pump if any part has been under water. Immediately call a qualified
professional technician to inspect the heat pump and replace any part of the control
system, which has been submerged.
The heat pump will produce condensation (water) while in operation. The heat pump base
is designed to allow the condensation to exit through the bottom drain port. The
condensation will increase as the outdoor air humidity level increases. Check the following
at regular intervals to ensure proper condensate drainage:
1. Visually inspect and clear the bottom drain port of any debris that could clog the port.
2. Keep the air intake area and discharge area clear of debris so the airflow through the
heat pump is not restricted. The cooler discharge air should not accumulate and be
drawn into the side air intake coils. During normal operation, the heat pump produces
10 to 20 liters of condensate per hour. If condensate drainage is above this range during
operation or if water continues to drain from the base when the heat pump is not in
operation for more than an hour, a leak in the internal plumbing may have occurred.
Call a qualified heat pump technician to investigate the problem.
Attention!
A quick way to verify that the water running through the drain is condensation water 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 water.

Maintenance and inspection
Maintenance
oCheck the water supply to the unit and the releaser often. Low water flow and air
entering into the system should be avoided, as this will diminish the units’ performance
and reliability. You should clean the pool/spa filter regularly to avoid damage to the
unit as a result of the dirty or clogged filter.
oThe area around the unit should be dry, clean and well ventilated. Clean the side
heating exchanger regularly to maintain good heat exchange and to save energy.
oOnly a certified technician should service the operation pressure of the refrigerant
system.
oCheck the power supply and cable connection often. Should the unit begin to operate
abnormally, switch it off and contact a qualified technician.
oIn winter, please discharge all water from the water pump and other systems to
prevent damage from freezing.
oYou should discharge the water at the bottom of the heat pump if the unit will not
work for an extended period of time. You should check the unit thoroughly and fill the
system with water fully before using it for the first time after a prolonged period of no
usage.
oRegularly clean the heat pump air suction grids. To that extend, we recommend the use
of “Griel soap”.
