General information

Product description

The models V80-3P/V130-3P/V250-3P are a range of

specically developed air/water heat pumps designed for

energy ecient heating of swimming pools or spa facilities.

The models have been developed and designed for the

Nordic climate. 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 refrigerant (R410a)

• Digital LED control

• Dynamic defrost function

• Built-in ow switch

• Union or anged connections depending on model

Functional principle

The pool heat pumps are V80-3P/V130-3P/V250-3P 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.

The heat pump must always be installed outside as it draws

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

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 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

You can read about some especially important points

concerning transport and storage, installation, usage,

maintenance and fault tracing 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.

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.

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.

In a combination involving solar collectors, you should

ensure that hot solar collector water does not ow directly to

the pool heat pump. If the solar collector water becomes too

hot you risk damaging the heat pump beyond repair.

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

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.

If the pool heat pump should be out of service over the

winter, it is important to drain the unit of water. The

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.

Service and support

The pool heat pumps are designed for reliable operation and

a long life. If a fault should occur you are advised to contact

the installation engineer who carried out the installation.

Always specify the product serial number, which you will nd

under the rating plate on the long side of the heat pump.

A basic guide to fault tracing is presented in section 4 -

Maintenance, service and fault tracing.

The unit may only be repaired by a qualied installation

engineer or an accredited workshop. Original spare parts

must be used for repairs.

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.

General information

Checklist installation

The following checklist provides a general description of how

the installation is carried out.

;Place the heat pump on a rm and horizontal surface.

;Open the service hatch and remove the enclosed

installation kit. Ensure that all component parts have

been delivered.

;Route the pipes for incoming and outgoing water.

Exercise care to ensure the inlet and outlet are installed

correctly. Mount the heat pump after the sand lter.

;Install a bypass for regulating the right partial ow for

the pool heat pump.

;Connect the electricity.

;Energise and check the settings.

;Put in operation and adjust the ow to the pool heat

pump to the right level.

Read more about start up in section 2 under the heading –

Starting up the unit.

Guarantee conditions

The component parts of the system must be transported,

stored and installed in accordance with the provisions

set out in the manual.

Repairs must be carried out by a qualied engineer. Original

parts must be used for repairs.

The guarantee becomes void if the conditions above are

violated.

Safety Regulations

It is especially important to take into account the following

safety instructions when handling, installing and using the

heat pump:

• Only qualied persons may work on the product’s

cooling system.

• Always disconnect the power supply before working on

the system.

Installation

A comprehensive installation description is provided in this chapter. This chapter is primarily intended for installation engineers, but

can also be read by the end user to increase his/her knowledge.

Positioning the unit

The pool heat pump will work ideally under the following

conditions:

;Access to fresh air

;Correct electrical installation

;Clean pool lter and correct pipe routing

In principle the pool heat pump can be placed anywhere

outdoors. However, do not place the pool heat pump

enclosed with restricted access to the air intake and air

exhaust (see the gure below). A structure with a roof is not

necessary.

Set up

The pool heat pump must be placed on a rm, horizontal

base and should not be placed next to or be installed with

brackets on sensitive walls with a lightweight structure. The

unit must be placed so that noise from the compressor and

fan disturb the surroundings as little as possible.

The unit must stand rmly, straight and raised from ground

level. Ensure a rm and at surface is provided.

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 outdoor section must be placed so that the air supply to

the evaporator coil is sucient. Otherwise the power output

and eciency will be impaired.

Leading o condensation water

Outdoor air is cooled in the evaporator by approximately

5-10 degrees. The water vapour then condenses on the

evaporator coil ns. If the air humidity is high this can result

in many litres of water per hour. The condense water

is discharged through an outlet on the short side. It is

important to consider the position of the unit so that the

condense water can be led o correctly.

Pipe connections

The pool heat pump is connected to the pool’s circulation

system with the help of the supplied 63 mm union couplings

(applies to V80-3P/V130-3P). Screw connections to the heat

exchanger must be tightened by hand.

V250-3P has DIN110 ange connections with seals and blind

anges on delivery.

A bypass coupling should be tted to enable setting of the

correct partial ow to the pool heat pump.

Bypass coupling

We recommend that a bypass coupling is tted to all

installations in order to adjust the right partial ow to the

pool heat pump.

Adjusting the bypass

1. Open all the valves

2. Check the incoming and outgoing water temperature,

see Section 3.

a. If there is no dierence in temperature, gradually close

the supply valve until the dierence is between 1 and

2 degrees.

b. If the dierence is above 2 degrees, gradually close

the bypass valve until the dierence is between 1-2

degrees

If the display shows E03, this means that the ow in the

system is too low, and that the bypass valve may need to be

closed tighter, or that the total ow of the purication system

is too low.

First open all the valves to simplify adjustment of the bypass.

Interconnection of multiple units

In order to save energy, it is recommended that several units

work together in parallel. In doing so, optimal use is made of

the heat pumps.

Series connection is also possible, but is only recommended

in cases where restrictions in the system in general do not

allow parallel connection.

See the gure below for the installation principle.

Electrical installation

The electrical connection is made to the pool heat pump’s

junction box located behind the front panel. A safety switch

must be located visibly on the unit. The working switch

protects against unintentional starting, for example, when

servicing the unit. The unit must be connected to earth in

order to achieve adequate earthing protection.

There is an additional connection on the terminal block, To

Pump. This connection can be used if you wish to connect a

separate circulation pump to the pool heat pump.

See the wiring diagram in section 5 for more detailed

information about the electrical connection.

Starting up the unit

In order to heat the pool or spa water, the pool’s circulation

pump must start and water needs to circulate through the

heat exchanger. The following procedure should be followed

when starting the pool heat pump for the rst time:

1. Start the pool’s circulation pump. Check that there is a

ow to and from the pool heat pump.

2. Switch on the supply voltage, press ON/OFF on the

display and the unit will start up after a few seconds.

3. After a few minutes, check that temperatures T03 and

T04 are lower than T05.

4. Stop the pool’s circulation pump and make sure that the

pool heat pump stops automatically and displays the

error E32. Also check that the heat pump starts again

automatically when the circulation pump has restarted.

5. The pool heat pump will only stop when it exceeds the

preferred temperature by 1 degree. The pool heat pump

will then start again when the temperature in the pool

drops by 1º below the required temperature.

Flow switch: The pool heat pump is equipped with a ow

switch that prevents starting in the event of insucient water

ow.

Time delay: The unit is tted with an approximate 5 minute

start delay to prevent repeated restarts and compressor

wear. Even a brief power failure activates the start delay of 5

minutes.

Installation

When connecting 3-phase units, make sure

that the phases are in correct order or the

machine won’t start. If the machine won’t

start at the rst setup, please swap two

phases around and the machine will start.

Maintenance, service and fault tracing

Winter drainage

It is very important to remember to drain the unit in winter if

it is out of service over that season! The guarantee does

not cover damage to the titanium heat exchanger due to

freezing! Drainage is made easy by loosening the pipe

connection to the inlet and outlet pipes, and by opening the

connection to the drain on models where this applies.

Maintenance

;Check the water ow regularly. Clean the pool/spa lter

regularly to prevent breakdowns to the unit.

;The area surrounding the unit must provide good

drainage and ventilation.

;Check the power supply and cable connections regularly.

If the unit does not function as designed, shut it down

and contact the service engineer.

;Review the evaporator coil on a regular basis, and clean

if necessary. Regular cleaning will guarantee maximum

eciency.

;Ahead of the winter shut-down – drain and cover!

Fault tracing

If a fault should occur you should always contact the

installation engineer who carried out the installation. Always

specify the product serial number, which you will nd under

the rating plate on the long side of the heat pump.

The fault tracing chart below provides information on

rectifying the most common problems. Always read

this before contacting the engineer who completed the

installation.

In the event of any uncertainty before winter

drainage, contact your dealer! An iced-up heat

exchanger due to forgotten winter drainage is

not covered by the guarantee!

Operating disturbance Cause Action

Set pool temperature not

reached.

1. The heat pump is o.

2. The heat pump is in cooling

mode.

3. The heat pump is too small for

the pool.

4. The outdoor air temperature is

too low.

5. The pool’s insulation is not

sucient.

1. Press the ON/OFF button.

2. Change the operating mode to heating mode as

set out in the section 3.

3. A larger heat pump or other heat source is

needed.

4. The season is over. Larger heat pump required.

5. The pool needs to be covered.

The heat pump ices up.

1. The pool temperature is too

low, below 18°C, which means

that the defrosting function is

not working.

2. High humidity. When

abnormal conditions such as

fog or unusually high humidity

occur, icing can be a greater

problem than normal.

1. The pool water needs to be warmer in order for

the defrost function to work normally.

2. Turn the unit o and back on again when it is

completely free of ice. If the problem persists,

contact your dealer.

Flow switch generates E03. 1. The ow is too low. 1. Make sure the purication system is running and

check the setting for bypass.
