1.2 Working principles
√High efficiency
With aCOP valueup to 5.0our heat pumpsare very efficient when transferring heat from theair to
the swimmingpool water. Youcan saveas much as80% of costcompared toan electrical heater.
Long life-span√
The heat exchangeris made of PVC & Titanium tube, which can withstandand prolong exposure to
swimming pool water.
Easy√ control and operation
The u nit is ve ry easy to o perate : simpl y switch it on a nd set th e desired po ol water temperature.
The system includes a micro-computer controller, allowing all operation parameters to be set.
Operation status can be displayed on the controller with LCD display.
√Heat pumps utilize the sun s free heat by collecting and absorbing energy from the outside air. This'
ene rgy is then co mpressed and trans ferred to the p ool wat er. You r exis ting water pu mp c ircu lates the
water throu gh th e heater, usua lly nex t to th e pool eq uipme nt, and t he water warm s up. The heat p ump
tim er coul d be set to operate du ring dayli ght hou rs, for exa mple, u suall y 9am to 5pm.
The u nit contai ns a fan tha t draws in o utside air a nd directs i t ove r t he su rfa ce of the EVAPO RATOR√
(energy collector).The liquid refrigerant within the EVAPORATOR coil absorbs the heat from the
out side ai r becom es a ga s.
The w arm gas in t he coil p asses through t he COMP RES SOR con centratin g and i ncreasing the heat to√
form a ver y hot gas which the n passes to th e CON DENSE R (water heat exc hange r).It is here t hat t heheat
exchange occurs as the hot gas gives off heat to the cool swimming pool water circulatingthrough the coil.
The p ool water becom es wa rmer, and t he hot ga s coolin g as it flow s th roug h th e CONDENSE R coil ret-√
urns to its liquid form and, after passing on through the CAPILLARY TUBE the whole process begins again,.
7℃The state of the heat pump technology can efficiently collect heat from theoutsideair downto the to√
10 range . For t rop ic and subtropi cal c limates, t his means th at the po ol ca n be maintained at 26 to 32℃℃

1.4 Location of heat pump installation
The unit will perform well on any location provided three factors are present:
1. Fresh air 2. Electricity 3. Pool filter piping
The unit may be installed virtually anywhere outdoors providingminimum distance requirements aremet
with respect to other objects (see diagram below).For indoor pools please consult your installer. If the
uni t is plac ed in a win dy area, no probl ems occ ur with e .g. the pilot li ght, as o ppo-sed to w hat i s often the
cas e with gas heaters .
Do no t place t he unit i n an encl osed ar ea wi th a limi ted air volu me where the u nit'sAttention:
discharged air will be re-circulatedor near shrubs that could block the air inlet. These locati-
ons deny the unit a continuous fresh air supply, which reduces its efficiency and may prevent a-
dequate heat yield.
See diagram below for minimum required distances.
Cautions
√Do no t put you r hands or any othe r object into the a ir outl et and fan. It coul d damag e the heat pum p and
cause injuries.
In case any abnormality was found in the heat pump, please cut off the power at once andcontact a√
professional technician.
It is strongly suggested to place a guard around the machine to keep children away from the heat pump.√

1 5 Distance from the pool.
Normally, the pool heat pump is installed within a 7.5 meter radius of the pool. The greater the distance
from the pool, the greaterthe heat loss from thepiping. Sincethe piping is buried forthe most part,
hea t loss is mini mal for dista nces of u p to 30 meters (15 meters to and from the p ump= 30 m eters to tal),
unless thesoil iswet orthe water levelis high.Heat lossper 30 meters could roughly be estimated at 0.6
kw-hour (2000BTU) 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,％.
1.6 Installation of the check-valve
Attention- When using automatic chlorine and PH dosage systems, it is ofuttermost importanceto protect
the h eat pum p fro m high conce ntrations o f these c hemic als that could co rro de the heat exc hanger.
Therefore, such systems should add thechemicals in the conduits locatedDOWNSTREAM of the heat
pum p and it is r eco mmended to i nstall a c heck- valve in order to prevent back flow when th ere is no water
circulation.
Damage to the heat pumpcaused by disregardinganyof theserecommendations will invalidate the warranty.

Adjust the by-pass as follows:
open the 3 valves completely
slightly close valve 1 until water
pressure has increased with approximately 100 to 200 grams,
close valve 3 about halfway to

Although the heat pump is electrically isolated from the rest of the unit, this only preventsImportant—
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. Make for adequate ground connection.
Check ifthe electrical mains voltage corresponds with the operating voltageof the heat pump prior to
hoo king up t he unit .
It is recommended to use a separate fuse(slow type-D-curve)as well as adequate wiring(see table below).
For h ori zontal models : remo ve th e panel o n the rig ht of the fa n openi ng.
For vert ica l model s: remove th e cur ve pane l in the front s ide.
Connect the electrical wires with the terminal block labelled Power Supply .“”
Next to this connection, thereis a second terminal block labelled Water Pump ,to which the filter“”
pump (max.5A/240V)can be connected. This is connectionmakes it possible to control filter pump
operation with the heat pump. See further at Parameter setting table (Parameter 9) for the different
possibilities.
Remarks
—for mo dels wi th 3 phas es, swi tch ing 2 pha ses may caus e in inve rsio n in the rotational direction
of electrical motors, which could damage the unit. Therefore,a protection device has been built in, which
wil l interrup t the circuit if th e conne ction has no t been performe d correctly.

1.10 First time start-up
Time delay— the unit is equipped with a built-in3-minute start delayincluded to protectelectrical
components and contacts. After this time delay, the unit will automatically be restarted. Even a
brief interruption of the power supply willactivate the startdelay and preventthe unit from starting
immediately. Additional interruptions of the power supply during the delay period will have no effect
on the 3-minute countdown.
Water flo w switch— the uni t is equi pped with a fl ow switch th at is switch ed on when eno ugh wate r has
flowed through the unit and that isswitched off when the waterflow becomes too low. (E.g. When the
filter pump is switched off).
Whe n the swi mming pool w ater is be ing hea ted b y the heat pum p, the incoming a ir is coo led down qui te
a bit , which c an ca use con densatio n on the fins of t he evaporat or. Con densed vol umes can atta in several
litres per hourunder highatmospheric humidity.Sometimes, this is wrongfullyinterpretedas a waterleak.
Dep endin g on the start ing temperature of the po ol wa ter a nd the ai r temperature, it can take s everal days
for the water to reach th e desired tempe rature. Coveri ng the pool ca n dra sti cal ly redu ced this per iod.
When all connections have been made and checked, you should follow these steps:
1. Turn on th e filte r pump. Chec k for l eaks and verify f low to and from the p ool.
2. Turn on the electrical power supply to the unit, then press the ON/ OFF key on the electronic control
pan el. The u nit sho uld start wh en the time de lay period h as lapsed .
3. When the unit has been running for a couple of minutes, check if the air leaving 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. Al l the uni t and fil ter pum p to ru n 24 hours a day until the d esired pool water tempe rature is reache d.
When theset temperature is reached,the unitswitches itself off.The unitwill now automatically restart
(as long as your filter pump is running) when the temperature of the pool water experiences a drop of
more than 1 below the set temperature.℃
Note- Inorder for the unitto heat the pool(or spa),the filterpump must be running sothat thewater can
circulate through the heat pump. Without this circulation, the heat pump will not start.
