2.INSTALLATION

2.1 Installation methods

Please observe

All drawings contains buffer tank , since this is normally used for better temperature balance form heat pump and heating / cooling system . The sensors are therefore placed in the buffer tank . If you don't have buffer tank in your system , the sensors needs to be put directly on the water lines . Make sure that you get good readings by only connecting the sensors to cop per pip es or similar .

Installation drawing of unit connected directly to hea ting sy stem. (not all installers use buffer tan k).

a. With ex terna l water pump, add by pass between turn and return line between indoor unit and external

circulation pump

b. Witho ut exte rnal water pump, an adjustable bypass (ball valve) is required to ensure flow for heat pump if thermostat close the flow in the heating system. c. External circulation pump needs to be connecte d to indo or unit w ater pump terminal (P0)

Minimum piping dimensions required. a. ≤ 6kW heat pump output, minimum 22 mm copper piping or similar b. ≤ 13 kW heat pump output, minimum 28 mm copper piping or similar. For 13 kW heat pump 35 mm

copper can be required if it is much fittings and angles. c. ≤ 20 kW heat pump output, minimum 35 mm copper piping or similar.

Please be aware of

All the sensors are put on the indoor unit . Please adjust the position o f senso rs acco rding to your real application . All sensors ( TW , TH and TC ) needs to be connected to the PCB to avoid failure codes , event hey are not in use in your application . Make sure to insulate the pipes and sensors if sensors are put direct ly on the w ater lines .

Application 1 For space heating

In this application heat pump is connected on the ret urn lin e of the heating system . The unit can be controlled by fixed or variable water temperatu re ( curv e , based o n ambient temperature ) . This heat pump has no internal back up , so an existing heating so urce li ke oil burner etc . needs to be connected as back up . The installation also demand s that th e backup source have a working controller to control the supply temperature to the heat ing sys tem . When the heating deman d exceeds the heat pump capacity , the backup source au tomat ically starts supporting the heat pump . This means the heat pump curve or temperature controller s hould b e set slightly above the existing heating source controller . Then heat pump will always have the priority . All sensors ( TW , TH and TC ) needs to be connected, even they have no function for the chosen application. Locate water temperature senso rs on ret urn lin e if no buffer tank is installed. Mak e sure the sensors have good contact with the pipe, and insulate th e pipes a nd sens ors.

E. Sensor cables

All temperature sensors are preinstalled in the unit, and the unit can be operated without any changes. Still for different applications it is possible to move the sensors to the place you wish to have the units temperature readings for the controller. For example if the unit is connected to a buffer tank or accumulating water tank, it is more efficient to let the heat pump be controlled by the water temperature in the water tank.

1. Disconnect the sensor with the quick connector inside the indoor unit.

2. Insert the sensor cable from indoor PCB through cable gland on top of indoor unit.

3. Connect the sensor cable which stick out on top of indoor unit with extension cable for sensor.

4. Connect the other side of extension cable with the sensor.

5. Place the sensor in right position, according to your application, as shown in the pictures below.

6.Make sure to let water temperature sensors to have good contact by using cooling past in sensor pockets, and insulate sensors located directly on water pipes.

2.6 Connection of refrigerant pipe

AWH9/11/13-V5+

A:For the unit with quick connector

Begin routing from the indoor unit and straighten out the pipes as you go.On the pipe ends in the

installation kit are cap nuts for connection to the cannot be installed incorrectly.Hold the connection

in place with one spanner

and tighten the cap nut

with the other,as

otherwise the connection

can be damaged.

Conect the installation

kit’s pipes to the

connections on the indoor

unit.First screw together

the screw connections by hand and then tighten using the spanners.Tighten the connection fully

without stopping.A hissing noise can be heard.Hold the connection in place with one spanner and

tighten the cap nut with the other.Tighten to at least 18Nm.Use a torque wrench if you are unsure

Never turn the fixed connections.Use the spanner only as a counter hold during connection.If a

counter hold is not used,the connections can turn,which can destroy them.Tighten the connections

24 hours after installation has been completed.

IMPORTANT:

Note that the pipes in the installation kit are filled with gas and must not be cut under any

circumstances.

The plastic plugs on the ends of the pipe must not be removed until the pipes are to be connected.

If the pipes are bent and causing leakage, the couplings must be loosened so that the non-return

valves close.

Route the pipes from the indoor unit and connect them in

the same way to the outdoor unit.

Refrigerant pipes must not be bent to a radius of less than

15cm(check with a cardboard template).Route the electrical

cable along the pipes.Bend the pipes carefully,a little at a

time.Do not bend the pipes too sharply.

2.INSTALLATION

Connect the installation kit's pipes to the connections on the

outdoor unit.First screw together the screw connections by

hand and then tighten using the spanners.

Tighten the connection fully without stopping.A hissing noise

can be heard.Hold the connection in place with one spanner and

tighten the cap nut with the other.

Never turn the fixed connections.Use the spanner only as a

counter hold is not used,the connections can turn,which can

destroy them.Tigthen the connections 24 hours after

installation has been completed.

Check the seals and tighten the couplings again 12-24

hours after installation. Check for leaks by wetting with

soapy water. Also check the connections at the indoor unit.

If no bubbles appear, the couplings are properly connected

and tightened!
