Condensation

connection

If the temperature falls below the

dew point, condensation will form

on the cooling ﬁns during cooling

mode.

A collection tray together with

a condensation pump and ﬂoat

switch are ﬁtted as standard below

the cooling ﬁns. Should the ﬂoat

switch trip a protective shutdown

due to inadequate removal of

the condensation, the pump will

switch on immediately and run on

for approx. three minutes.

■

The condensation pipe should

have a fall of min. 2 %.

This is the responsibility of

the customer. . If necessary,

ﬁt vapour diffusion tight

insulation.

■

If the level of the condensation

pipe on the unit is above

that of the outlet, route the

pipe vertically upwards (max.

1000 mm from the bottom

edge of the unit) and then with

a fall to the drain.

■

The condensation pipe from

the unit should run freely

into the drainage pipe. If the

condensation runs directly

into a sewer pipe, ﬁt a trap to

prevent any unpleasant odours.

■

When operating the unit at

outdoor temperatures below

0 °C, ensure the condensation

pipe is laid to protect it against

frost.

If necessary, ﬁt supplementary

pipe heating.

■

Once the pipe has been laid,

check the condensation drains

off and permanently seal it.

Tightness check

Once all the connections have

been established, the pressure

gauge station is attached as

follows to the Schrader valve (if

ﬁtted):

red = small valve

= injection pressure

blue = large valve

= suction pressure

Once connected, perform a

tightness test using dried nitrogen.

The tightness test involves

spraying a leak detection spray

onto the connections. If bubbles

are visible, the connections have

not been properly made. Re-

tighten the connection or prepare

a new ﬂange.

If the tightness test is successfully

completed, depressurise the

refrigerant pipes and start a

vacuum pump with an absolute

ﬁnal partial pressure of min. 10

mbar to remove the air in the pipe.

Any humidity present in the pipes

is also removed.

A vacuum of min. 20 mbar

abs. must be created!

CAUTION

The time required to generate

the vacuum is dependent on

the pipework volume of the

indoor unit and the length of the

refrigerant pipes. This always takes

at least 60 minutes.

Once any foreign gases and

humidity have been completely

extracted from the system, the

valves on the pressure gauge

station are closed and the valves

on the outdoor component are

opened as described in the chapter

on "Commissioning".
