Both BA-SVM 10-200 and AMS 10 are factory tested
for pressure and leakage, but the refrigeration pipe
connections between appliances should be checked
for leakage after installation.
When connecting the pipes, carrying out pressure
tests and leak tests, and creating the vacuum, re-
member to keep the service valves (QM35, QM36)
closed. In order to fill the pipes of BA-SVM 10-200
with refrigerant, they must be reopened.
Connections:
Principle:
• Refrigerant pipes (both liquid and gas) must be
insulated for the purpose of thermal insulation
and in order to avoid condensation.
• Use insulation that can withstand at least 120°C.
Use a vacuum pump to remove all air. Apply suction
for at least one hour and end pressure after evacua-
tion must be 1mbar (100 Pa, 0.75 Torr or 750 micron)
absolute pressure. If the system is still damp or leak-
ing, the vacuum will decrease after the draining has
finished.
CAUTION
The pipe connection between the indoor unit and the
outdoor unit must be leak tested. Then create a vac-
uum for the completed pipeline after finishing instal-
lation, in accordance with the applicable regulations.
Only nitrogen must be used for compression and dry-
ing of the completed pipeline.
TIP
To achieve a better end result and speed up creation of
the vacuum, please follow the below points:
•
The pipelines should have the correct diameter
and length.
•
Drain the system to 4 mbar and fill it with dry
nitrogen to atmospheric pressure.
AMS 10 is delivered complete with the refrigerant
required for the installation of refrigerant pipes with
lengths of up to 15 m on either side.
If the length of the refrigerant pipes exceeds 15 m,
extra refrigerant must be added in the amount of
0.02kg/m for BA-SVM 10-200/6 or 0.06 kg/m for BA-
SVM 10-200/12.

NOTE
All connections and work related to the refrigeration
system must be carried out by a person with the prop-
er authorisations and certificates.
NOTE
The maximum permissible length of the refrigerant pipes
can be 30m, however this requires topping up the sys-
tem with refrigerant after a length of 15m is exceeded.
