Vacuum Pump - Alpha-InnoTec HT 6Split Installation And Operating Manual

Pressure test and leakage test
Both HT 6Split / HT 12Split and LSplit are facto-
ry-tested for pressure and leakage, but pipe connec-
tions between the devices must be checked when the
installation has been completed.
IMPORTANT
Pipe connections between devices must undergo a
pressure test and leakage test after completing the in-
stallation process, according to applicable regulations.
Use nitrogen only for system compression and rinsing.

Vacuum pump

Use a vacuum pump to remove all air. Turn on ex-
traction for at least one hour. Final pressure, after
emptying, must total 1 mbar (100 Pa, 0.75 Tr or 750
microns) of absolute pressure. If the system is still
moist or is leaking, negative pressure will grow after
the end of emptying.

ADVICE
ate emptying, follow the following sections.
• Pipelines should have the largest diameter possi-
ble, and be as short as possible.
•

Filling the system with a cooling medium
LSplit is supplied together with a cooling medium for
cooling medium of max. length of 15 m. If the length
of the cooling medium pipes exceeds 15 m, supple-
ment the cooling medium in the volume of 0.06 kg/m
for HT 12Split and 0.02 kg/m for HT 6Split.
CAUTION
The maximum permissible length of the refrigerant pipes
can be 30m, but this requires topping up the installation
with a refrigerant after exceeding 15m.

Insulation of cooling medium pipes
• Cooling medium (both gas and liquid) pipes must
be insulated to provide thermal insulation and
prevent condensation.
