*absolute service pressure: min 1 bar/max 11 bars
Periodic Maintenance
9. Vacuum the compressor (low side) and prepare it
for inclusion in the system. There is a service valve
on the suction line and on the evaporator. Use these
valves to vacuum the compressor.
10. Open the oil-line shutoff valve. Sever damage to the
compressor can result if the oil-line shutoff valve is
closed when the compressor is started.
11. Open the other compressor isolation valves.
Note:
this procedure assumes that the oil that is put into
the filter housing does not have contaminants such as
non-condensable gases. The oil forces these gases out
of the filter and oil-line shutoff valve, without the need
to pull a vacuum on this small volume. If the oil has
been in an open container or is otherwise contaminated,
then this small volume must be subject to vacuum as
well. However, the filter cavity is full of oil. Therefore, be
sure to use a flash tank in line with the vacuum pump to
ensure that the oil that is pulled out of the filter cavity
does not slug the vacuum pump.
WARNING!
Catastrophic damage to the compressor will
occur if the oil-line shutoff valve or the isolation valves
are left closed on unit startup.
