INTRODUCTION

1. Introduc tion

Thank you for purchasing our reversible heat pump water heater for your

Swimming Pool/Pond. Our heat pump was produced in accordance with the

current European Standard and it is now ready to be used. Please read this

manual carefully before install the heat pump, otherwise it may lead to damage

to the heat pump or may injure operators as well as cause financial loss.

The heat pump should be installed by a professionals or qualified technicians.

1.1 Heat Pump Technology

Heat pumps utilize the sun's free heat by collecting and absorbing energy

from the outside air. This energy is then compressed and transferred to the

pool/pond water. Your existing water pump circulates the water through the

heater, usually next to the pool equipment, and the water warms up.

The unit contains a fan that draws in outside air and directs it over the

surface of the EVAPORATOR (energy collector).The liquid refrigerant within

the EVAPORATOR coil absorbs the heat from the outside air becomes a

gas.

The warm gas in the coil passes through the COMPRESSOR concentrating

and increasing the heat to form a very hot gas which then passes to the

CONDENSER (water heat exchanger).It is here that the heat exchange

occurs as the hot gas gives off heat to the cool swimming pool water

circulating through the coil. The pool water becomes warmer, and the hot

gas cooling as it flows through the CONDENSER coil returns to its liquid

form and, after passing on through the CAPILLARY TUBE the whole process

begins again.

The state of the heat pump technology can efficiently collect heat from the

SAFETY PRECAUTIONSoutside air down to the 7 to 10 range. For tropic and subtropical climates,

this means that the pool can be maintained at 26 to 32 .

1.2 Heat Pump Features

►High Efficiency

With a COP value up to 6.0 our heat pumps are very efficient when transferring

heat from the air to the swimming pool water.With the DC Inverter technology

and heat pump technology, you can save as much as 80% of cost compared to

an electrical heater.

►Long Life-SpanThe heat exchanger is made of PVC & Titanium tube, which can withstand and

prolong exposure to swimming pool/pond water

►Easy Control and Operation

The unit is very easy to operate: simply switch it on and set the desired pool

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.

2. Safety Precaution s

2.1 General

1) Before install the heat pump, please confirm the local power supply is in

accordance with the requirement of the heat pump, refer to the Technicaldata and the Wiring diagram provided in this manual.

SAFETY PRECAUTIONS

2) Connecting the heat pump to a ground wire is necessary, in order to

prevent electrical shock caused by an unexpected short circuit inside unit.

3) Please install electrical protection devices according to local regulations.4) The unit must be installed on reliable base or supporting framework.

5) If the unit is to be installed on the floor, its base or supporting framework

should be heightened, to avoid ingression of accumulated water in rainy

season. In snowy areas, it is important to prevent accumulated snow from

blocking up the air-out. The recommended height is 20cm to 30cm.

6) Install the drainage pipe before fix the heat pump to the ground. There are

two drainage hole on the heat pump base, which could be connected to

the drainage pipe with a pipe arches which contains in spareparts.

7) Drain ditch or other facilities should be arranged under the heat pump, to

avoid the environment influence because of water discharge.8) Ensure the unit is well ventilated, direction of air exhaust is kept away

from windows of neighboring buildings, and the exhaust air cannot flow

back.

Moreover, adequate service clearance should be kept around the unit.

9) DO NOT put fingers or sticks into the ventilative fan.

10)The unit should not be installed at places accompanied with oil,

inflammable gas, corrosive components e.g. sulfur compound, or

high-frequency equipment.

11) The heat pump is usually placed next to a house, which gives a directedsound distribution that should be considered, so it should take proper

action to reduce the noise impact.

12) Cut off the power supply before maintaining the unit, and the maintenance

work should be carried out by professional.

13) If any abnormity occurs in the heat pump, such as abnormal noise or

burned smell, cut off the power supply immediately, and contact

professionals for check and repair.

14) Clean the heat pump with follow instructions:

►Before cleaning, cut off power supply firstly to avoid potential danger.

►Don't rinse the unit by water because it may lead to electric shock.

2.2 Transportation and Storage

The heat pump MUST be transported and stored VERTICALLY!

3. Installation

3.1 Remarks

►The factory only provides the heat pump unit the other parts including a

contingent by pass are to be provided by the user or the installer.►Connect the drainage pipe with a pipe arches which contains in spare

parts to heat bottom base of the heat pump before install the heat pump

INSTALLATION

3.4 Location of the Heat Pump

The unit will perform well on any location provided three factors are present:

Fresh air - Electricity - Pool fi lter piping

The unit may be installed virtually anywhere outdoors providing minimum

distance requirements are met with respect to other objects (see diagram

below).

For indoor pools please consult your installer.

If the unit is placed in a windy area, no problems occur with e.g. the pilot light,

as opposed to what is often the case with gas heaters.

At tent io n: Do not place the unit in an enclosed area with a limited air volumewhere the unit's discharged air will be re-circulatedor near shrubs that could

block the air inlet. These locations deny the unit a continuous fresh air supply,

which reduces its efficiency and may prevent adequate heat yield.

See diagram below for minimum required

INSTALLATION3.5 Pool/Pond Connection Diagram

(Just for reference, can adapt according to reality.)

3.6 Electric Hook-Up

Although the heat pump is electrically isolated from the rest of the unit, this only prevents

the passage of electricity to or from the pool/pond water. Grounding the unit is still

required to protect yourself from short circuits inside the unit. Make for adequate groundconnection.Check if the electrical mains voltage corresponds with the operating voltage of

the heat pump prior to hooking up the unit.

Note:

1. Customer could choose to use the Gang Switch and Electrical Heating. If not

needed, just leave it free without connecting.

2. For Interlock Switch, please make sure it is connected, otherwise the compressor

will not start. (Before leaving our factory, we have short connected it. Leave it like

this if you do not need to use it.)

3. If need electrical heating, and with power larger than 1KW, please do not connect

the electrical heating directly to PCB controller, but should be controlled by a A.C.

contactor.

INSTALLATION3.7 Condensatio n

When the swimming pool water is being heated by the heat pump, the

incoming air is cooled down quite a bit, which can cause condensation on the

fins of the evaporator. Condensed volumes can attain several liters per hour under high atmospheric humidity. Sometimes, this is wrongfully interpreted as

a water leak.

3.8 First Time Start-Up

When all connections have been made and checked, you should follow these

steps:

1)Turn on the filter pump. Check for leaks and verify flow to and from the pool

2)Turn on the electrical power supply to the uni, then press the ON/OFF key on

the electronic control panel. The unit should start when the time delay period

has lapsed3)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)All the unit and filter pump to run 24 hours a day until the desired pool water

temperature is reached.When the set temperature is reached, the unit

switches itself off. The unit will now automatically restart as long as your filter

pump is running) when the temperature of the pool water experiences a dropof more than 1°C below the set temperature.
