Incline of the condensate line

minimum

2% incline

The condensate hose is designed

to be connected on the left-hand

side (as viewed from the front).

All electrical installation

work should be performed

by specialist contractors.

Disconnect the power supply

when connecting the electrical

terminals.

! ATTENTION

Leak testing

Pumping down to

vacuum

Once all the connections have

been made, the pressure gauge

station is attached to the Schrader

valve as follows (if ﬁtted):

red = small valve

= injection pressure

blue = large valve

= suction pressure

Following connection of the quick-

release couplings, the connections

are checked using leak detection

spray and suitable devices for leak-

tightness. If leaks are found, the

connections have not been made

properly. Tighten the connection

or, if necessary, remove the quick-

release coupling and check for

contamination or damage.

A vacuum of min. 20 mbar

must be created!

! ATTENTION

The time required to generate the

vacuum is dependent on the

pipe 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

"Commissioning" section.

Electrical connection

A mains cable must be installed

as voltage supply and a control

cable to the indoor unit. The air

conditioning unit should be fused

in accordance with the technical

data. The pre-installed control

cable on the indoor unit must be

laid to the outdoor component.

■

We recommend installing

a main / repair switch on the

building close to the indoor

unit.

■

If an optionally available

condensation pump is used

on the unit, then an additional

relay for the shut-off contact

of the pump will be needed

to increase the switching power

to shut off the compressor.

Both units are pre-filled with

refrigerant. Pumping down to

vacuum is not required before

first commissioning.

! ATTENTION

Condensate draining and

ensured discharge

Condensate connection

If the temperature falls below the

dew point, condensation will form

on the ﬁnned condenser during

heating operation.

A condensate drip pan should be

installed on the underside of the

unit to drain any condensate.

■

The condensate drain pipe to

be installed on-site must be in-

stalled with a in cline of at least

2 % for good drainage.

If necessary, ﬁt vapour density

insulation.

■

When operating the system at

outdoor temperatures below

4 °C, care must be taken that

the condensate line is frost

protected. The lower part of the

housing and condensate pan

are to be kept frost free in order

to ensure permanent drainage

of the condensate.

If necessary, ﬁt supplementary

pipe heating.

■

After completed installation,

check that the condensate

drainage is unobstructed and

ensure that the line is leak tight.

Ensured discharge in the event of

leakage

Local regulations or environmen-

tal laws, for example the German

Water Resource Law (WHG), can

require suitable precautions to pro-

tect against uncontrolled draining

in case of leakage to provide for

safe disposal of escaping refrigera-

tor oil or hazardous media.
