Outdoor unit for air to water heat pump
4PW49635-1A
Installation manual

Vacuum drying
To remove all moisture from the system, proceed as follows:
1. Evacuate the system for at least 2 hours to a target vacuum of
–100.7 kPa.
2. Check that, with the vacuum pump turned off, the target vacuum
is maintained for at least 1 hour.
3. Should you fail to reach the target vacuum within 2 hours or
maintain the vacuum for 1 hour, the system may contain too
much moisture.
4. In that case, break the vacuum by pressurizing with nitrogen gas
to a gauge pressure of 0.05 MPa (0.5 bar) and repeat steps 1 to
3 until all moisture has been removed.
5. The stop valves can now be opened, and/or additional
refrigerant can be charged (see "8.3. Method for adding
refrigerant" on page 11).
7.4. Precautions when connecting field piping and
regarding insulation
■ Be careful not to let the indoor and outdoor field piping come into
contact with the compressor terminal cover.
If the liquid-side piping insulation might come into contact with it,
adjust the height as shown in the figure below. Also, make sure
the field piping does not touch the bolts or outer panels of the
compressor.
■ When the outdoor unit is installed above the indoor unit the
following can occur:
The condensated water on the stop valve can move to the
indoor unit. To avoid this, please cover the stop valve with
sealing material.
■ If the temperature is higher than 30°C and the humidity is higher
than RH 80%, then the thickness of the sealing materials should
be at least 20 mm in order to avoid condensation on the surface
of the sealing.
■ Be sure to insulate the liquid and gas-side field piping.
(The highest temperature that the gas-side piping can reach is
around 120°C, so be sure to use insulating material which is
heat resistant.)
8. CHARGING REFRIGERANT
To avoid compressor breakdown. Do not charge the refrigerant
more than the specified amount.
■ This outdoor unit is factory charged with refrigerant and
depending on pipe sizes and pipe lengths some systems require
additional charging of refrigerant. See "Calculating the additional
refrigerant charge" on page 11.
■ In case re-charge is required, refer to the nameplate of the unit.
The nameplate states the type of refrigerant and necessary
amount.
8.1. Important information regarding the refrigerant
used
This product contains fluorinated greenhouse gases covered by the
Kyoto Protocol. Do not vent gases into the atmosphere.
Refrigerant type: R410A
GWP
(1)
value: 1975
(1)
GWP = global warming potential
Please fill in with indelible ink,
■➀ the factory refrigerant charge of the product,
■➁ the additional refrigerant amount charged in the field and
■➀+➁ the total refrigerant charge
on the fluorinated greenhouse gases label supplied with the product.
The filled out label must be adhered on the inside of the product and
in the proximity of the product charging port (e.g. on the inside of the
service cover).
After opening the stop valve, it is possible that the pressure
in the refrigerant piping does not rise. This might be
caused by e.g. the closed state of the expansion valve in
the outdoor unit circuit, but does not present any problem
for correct operation of the unit.
Any exposed piping may cause condensation or burns
if touched.

■ When servicing the unit requires the refrigerant
system to be opened, treatment and evacuation of
refrigerant must be done in accordance with relevant
local and national legislation.
■ Refrigerant cannot be charged until field wiring has
been completed.
■ Refrigerant may only be charged after performing the
leak test and the vacuum drying (see above).
■ When charging a system, care shall be taken that its
maximum permissible charge is never exceeded, in
view of the danger of liquid hammer.
■ Charging with an unsuitable substance may cause
explosions and accidents, so always ensure that the
appropriate refrigerant (R410A) is charged.
■ Refrigerant containers shall be opened slowly.
■ Always use protective gloves and protect your eyes
when charging refrigerant.
■ When performing service on the unit requiring the
refrigerant system to be opened, refrigerant must be
evacuated according to local regulations.
■ When the power is on, please close the front
panel when leaving the unit.
