After ��u��e����fully �ompleting the
leak te��t, the va�uum pump ��hould
be �onne�ted to the valve �onne�-
tion�� on the outdoor unit through
the manometer ��tation (��ee “Leak
te��t” ��e�tion) and a va�uum
��hould be generated.�
Before initial operation of the unit
and after any work on the refriger-
ating �ir�uit, the following �he�k��
mu��t be performed and do�ument-
ed in the in��tallation log:
■�
Che�k all refrigerant pipe�� and
valve�� for leak�� and for unin-
tentional ��wapping of ��u�tion
and inje�tion pipe�� u��ing leak
dete�tion ��pray or ��oapy water
when unit i�� ��topped.�
■�
Che�k refrigerant pipe�� and
in��ulation for damage.�
■�
Che�k ele�tri�al �onne�tion be-
tween indoor unit and outdoor
unit for �orre�t polarity.�
■�
Che�k all atta�hment��, mount-

used is always added in liquid
form!
CAUTION
Initial operation
�nitial operation mu��t be �arried
out in line with the initial opera-
tion �ertifi�ate and do�umented
a��ordingly.�
On�e all �omponent�� have been
�onne�ted and te��ted, the ��y��tem
�an be ��tarted up.�
To en��ure proper fun�tioning,
a fun�tional te��t ��hould be per-
formed before handover to the
operator to identify any irregulari-
tie�� during operation of the unit.�
Thi�� �he�k depend�� on the indoor
unit in��talled.�
The pro�edure�� are do�umented
in the operating manual for the
indoor unit to be operated.�
Functional test and test run
Te��t the following point��:
■�
�mpermeability of refrigerant
pipe��.�
■�
Smooth running of �ompre����or
and fan.�
■�
Di���harge of �old air from
indoor unit and heated air from
outdoor unit in �ooling mode.�
■�
�un�tional te��t on indoor unit
and all program ��equen�e��.�
■�
Che�k ��urfa�e temperature of
��u�tion pipe and identify any
evaporator overheating.� To
To
To
mea��ure the temperature, hold
the thermometer on the ��u�tion
pipe and ��ubtra�t the boiling
point temperature read from
the manometer from the mea��-
