Connect the domestic hot water tank module to the heat
pump module
Refer to the unpacking instruction sheet.
■
If the domestic hot water tank module is put next to the unit,
installing of the EKFMHMSAA kit is necessary. Refer to the
manual of that kit.
■
Make sure to check if the speed setting of the pump is set in
position III if the domestic hot water tank module is mounted on
top of the heat pump module.
Connecting the water circuit
Water connections must be made. The location of the water inlet
connection and the water outlet connection on the unit is shown in
the chapter
5.2. "Overview of the domestic hot water tank module" on
page
4.
WARNING
Be careful not to deform the unit
piping by using excessive force when
connecting the piping. Deformation of
the piping can cause the unit to
malfunction. Use two wrenches as
shown in the figure.
If air, moisture or dust gets in the water circuit, problems may occur.
Therefore, always take into account the following when connecting
the water circuit:
■
Use clean pipes only.
■
Hold the pipe end downwards when removing burrs.
■
Cover the pipe end when inserting it through a wall so that no
dust and dirt enter.
■
Use a good thread sealant for the sealing of the connections.
■
When using non-brass metallic piping, make sure to insulate
both materials from each other to prevent galvanic corrosion.
■
Because brass is a soft material, use appropriate tooling for
connecting the water circuit. Inappropriate tooling will cause
damage to the pipes.
Connect the pressure relief valve (field supply) and drain
■
In accordance with relevant local and national regulations, a field
supplied pressure relief valve with an opening pressure of
maximum 10 bar must be connected to the pressure relief valve
connection.
■
Make sure to provide a proper drain for the field supplied
pressure relief valve to avoid any water coming into contact with
electrical parts.
CAUTION: Requirements to discharges
■
Discharge piping, drain valves, etc.
positioned away from any electrical components.
■
All discharge pipe work must be installed in a
continuously downward direction and in a frost-free
environment. It must be left open to the atmosphere.
DANGER of burning and scalding
The discharge pipe must terminate in a safe, visible
position without forming any risk to persons in the vicinity.

Domestic hot water heat pump
4PW65342-1A – 10.2010
Connect the drain pan
During operation and depending on operation conditions the heat pump
module collects condens water in the drain pan at the bottom of the unit.
Make sure to provide a proper drain connection to this drain pan.
CAUTION: Requirements to drain piping

7.2. Precautions when connecting field piping and
regarding insulation
The complete water circuit, inclusive all piping, must be insulated to
reduce loss of heat.
If the indoor ambient temperature is higher than 30°C and the
humidity is higher than RH 80% then the thickness of the insulation
materials should be at least 20 mm in order to avoid condensation on
the surface of the insulation.

HARGING WATER
8.1. Method for adding water
1
Connect the water supply to the unit
2
Open each hot water tap in turn to expel air from the system
pipe work
3
Open the field installed hot water shut off valve
4
Open the field installed cold water supply valve
5
Close all hot water taps after all air is expelled
6
Check for leaks
7
Manually operate the field supplied pressure relief valve to
ensure free water flow
CAUTION
Immediately after installation, the domestic hot water tank
must be flushed with fresh water. This procedure must be
repeated at least once a day for the first 5 consecutive
days after installation.
must be
The drain piping must be positioned away from any
electrical components.
The drainpipe must terminate in a safe, visible position
without forming any risk to persons in the vicinity.
All drain pipe work must be installed in a continuously
downward direction and in a frost-free environment. It
must be left open to the atmosphere.
