General information

Product description

The models GJPACW1-15/20/30 and
GJPACW1V-15/20/30/40/60 are a range of specically
developed air/water heat pumps designed for energy
ecient heating of swimming pools or spa pools. The models
have been developed and designed for the Scandinavian
climate by Gullberg & Jansson AB. The pool heat pumps are
designed to work with good eciency and a low noise level.

All models feature:

Titanium heat exchangers resistant to chlorine and salt •
water
Environmentally friendly and eective coolant (R410a)•
Digital LED control with timer•
Dynamic defrosting function for an extended pool •
season
Flow switch and union couplings for safe operation and •
easy installation
Stainless steel casing•

Functional principle

The pool heat pumps GJPACW1-15/20/30 and
GJPACW1V-15/20/30/40/60 are primarily used for heating,
but can also be used for cooling. The models are controlled
via a ow switch and in order to work the pool’s circulation
pump must be running.

The pool heat pump works with the greatest energy
eciency when there are small dierences in temperature
between the inlet and outlet. The recommendation is 1-2
degrees dierence between the inlet and outlet. The water
ow is regulated via a bypass coupling. Read more about the
bypass coupling in section 2 – Installation.

All models are developed to guarantee good eciency in
the Nordic climate. However, it is important to be aware that
the degree of eciency is dependent on the surrounding
outdoor temperature and the temperature of the pool
water. The heat pump can be seen to perform with dierent
eciency during dierent parts of the year depending on
the outdoor conditions. At the start of the season, when
the water in the pool is cold, the heat pump needs to
work continuously for a long period to produce the right
temperature in the pool. When the pool water has reached
the required temperature, the heat pump automatically stops
and starts as required. It is always cost-eective to cover the
pool when not in use, especially at night. Approximately 60
– 70 % of the heat disappears from the water surface of the
pool. Covering also reduces the heat pump’s running time.

A Gullberg & Jansson heat pump must always be installed
outdoors, as it collects its energy from the surrounding air.
It must be well ventilated and must not be enclosed or in
any other way shielded so the air circulation is impaired. The
circulation of the air between the intake and exhaust impairs
eciency. Avoid installation close to sensitive walls, for
example, bedroom rooms.

Frost or ice can form on the heat pump’s evaporator. This is
completely normal. An automatic defrosting cycle will start to
melt the ice. After the defrosting cycle the heat pump starts
its standard program and continues to heat the pool.
The models are designed for pool heating during May to
September, which can be considered as a normal pool
season. The swimming pool heat pump normal working
condition is between 5 and 40 °C ambient temperature and
between 15 and 40 °C inlet water temperature.

This chapter provides background information about the pool heat pumps covered in this Installation and Maintenance Guide.
Important information, guarantee conditions and safety instructions are also presented here. This chapter is intended for both users
and installation engineers.

Important information

Especially important points concerning transport and
storage, installation, usage, maintenance and fault tracing are
presented below.

Transport and storage

Models designed to be transported vertically must be
transported in this way. This is because the suspension inside
the compressor can be damaged if the unit is laid down. If
the heat pump is tilted during installation or draining this
should be done with care and for the shortest time possible.

The original packaging is intended to be used to reduce the
risk of transport damage.

Remove the packaging and before installation check that the
heat pump has not been damaged during transport. Report
any transport damage to the forwarding agent.

Installation

The pool heat pump must be installed by a qualied
installation engineer and placed outdoors. The unit must
stand rmly, straight and raised from ground level. Provide a
rm and at surface, for example, garden slabs, concrete bed,
Leca blocks or similar.

Noise propagation must be taken into consideration when
positioning during installation. Positioning of the unit must
be done so that noise from the compressor and fan disturb
the environment as little as possible.

Large amounts of melt and condensation water can be
discharged during defrosting and operation. Consequently, it
is important to provide good drainage and run-o.

The units must stand freely so that air is not prevented to
pass the evaporator. Avoid a placement that produces cold
air circulation as this reduces the output of the heat pump.

Use and operation

The parameters on the display are set at the factory and do
normally not need to be adjusted. The temperature is set
to 27 °C. If you wish to increase the temperature, check rst
to ensure that your wishes of a high temperature do not
contravene any guarantees concerning the general pool
construction.

Maintenance procedures

It is important to drain the water from the pool heat
pump before the winter. The material guarantee does not
cover damage due to freezing on account of insucient
maintenance. The heat exchanger can also be ushed out to
remove any remaining deposits ahead of winter drainage.
Read more about drainage in section 4 - Maintenance, service
and fault tracing.

Perform regular checks to ensure that the inlet grille is not
blocked by leaves, snow, etc. In addition, make sure that
excessive frost or ice does not build up below the unit during
cold weather conditions.

The outer case can be cleaned using a damp cloth if
necessary. Take care not to scratch the unit. To minimize
ageing of the surface, it’s recommended to apply wax at least
once every year.

Service and support

GJPACW1-15/20/30 and GJPACW1V-15/20/30/40/60 are
designed for reliable operation and a long life. If a fault
should occur you should always contact the installation
engineer who carried out the installation. If the installation
engineer in turn considers it to be a question of a material
or manufacturing fault, he/she will contact us for inspection
and action to rectify the problem. Always state the product’s
manufacturing number. The number can be found on the
rating plate below the LED display. A basic guide to fault
tracing is presented in section 4 - Maintenance, service and
fault tracing.

Miscellaneous

The unit may only be repaired by a qualied installation
engineer or an accredited workshop. Original spare parts
must be used for repairs.

Solar collectors and heat pumps can be combined, however,
please contact the dealer or G & J regarding any uncertainty
with the installation. It is important to avoid connecting the
hot solar collector water directly to the pool heat pump. If the
solar collector water becomes too hot you risk damaging the
heat pump beyond repair.

The proof of installation for registration at Gullberg & Jansson
AB is enclosed with the installation. It is important that this is
completed and posted at the earliest possible date!

Installation material is enclosed inside the
machine. Open the cover and remove the
material before installation. Note that the
installation engineer provides pipes and
the bypass coupling for the installation.
