After successfully completing the

leak test, the vacuum pump should

be connected to the valve connec-

tions on the outdoor unit through

the manometer station (see “Leak

test” section) and a vacuum

should be generated.

Before initial operation of the unit

and after any work on the refriger-

ating circuit, the following checks

must be performed and document-

ed in the installation log:



Check all refrigerant pipes and

valves for leaks and for unin-

tentional swapping of suction

and injection pipes using leak

detection spray or soapy water

when unit is stopped.



Check refrigerant pipes and

insulation for damage.



Check electrical connection be-

tween indoor unit and outdoor

unit for correct polarity.



Check all attachments, mount-

ings etc. for proper retention

and correct level.

Basic pipe length Additional quantity

Up to 5 m inclusive -

5 m to max. 15 m 22 g/m

Adding refrigerant

The unit has a basic ﬁlling level of

refrigerant.

For basic refrigerant pipe lengths

of more than 5 m, additional re-

frigerant must be added, as speci-

ﬁed in the table below:

Before initial operation

Make sure that the refrigerant

used is always added in liquid

form!

CAUTION

Initial operation

Initial operation must be carried

out in line with the initial opera-

tion certiﬁcate and documented

accordingly.

Once all components have been

connected and tested, the system

can be started up.

To ensure proper functioning,

a functional test should be per-

formed before handover to the

operator to identify any irregulari-

ties during operation of the unit.

This check depends on the indoor

unit installed.

The procedures are documented

in the operating manual for the

indoor unit to be operated.

Functional test and test run

Test the following points:



Impermeability of refrigerant

pipes.



Smooth running of compressor

and fan.



Discharge of cold air from

indoor unit and heated air from

outdoor unit in cooling mode.



Functional test on indoor unit

and all program sequences.



Check surface temperature of

suction pipe and identify any

evaporator overheating. To ToTo

measure the temperature, hold

the thermometer on the suction

pipe and subtract the boiling

point temperature read from

the manometer from the meas-

ured temperature.



Document the measured tem-

peratures in the initial operation

log.
