General operation
The vacuum pump is supplied with the following standard accessories.
1.
An electrically operated solenoid valve which can easily be connected onto the inlet of the
vacuum pump. This solenoid valve will ensure that the vacuum is maintained in the event of
power to the pump being interrupted.
2.
A vacuum gauge that allows you to check the depth of vacuum in the system after evacuation
and also monitor for system leaks.
3. An oil mist filter. This filter will avoid that excessive oil vapour will be exhausted from the
pump when evacuating large amounts of air.
4. A non return valve on the inlet to prevent oil migrating from the pump into the evacuated
system when the pump is turned off.
5. A dual voltage switch allows an easy change from 220V to 110V operation.
6.
A 180 cm (72”) charging hose to connect the pump to a manifold gauge set or to the system to
be evacuated.
7. The electric motor has thermal and electric overload protection to prevent the windings from
damage if the electric motor becomes too hot or if the current gets too high, due to seizer or
other mechanical damage.
8.
The pump is dual cycle and will operate on both 50 Hz and 60 Hz
.
The minimum cold start temperature of the pump is 0°C and below this temperature an external
heater should be used to a guarantee trouble free start up
.
An optional manifold bracket can be supplied which is fitted to the pump handle and this enables
quick and easy attachment of a 1, 2, 4 or 5 valve manifold to the pump.
The pump can be supplied with different types of electrical connections/plugs. Please specify
model requested.
The pump can be used on all CFC, HCFC and HFC refrigeration systems and for continuous use on
CFC and HCFC systems ITE-205-P mineral vacuum pump oil is recommended.
For use on HFC systems, we recommend the use of ITE-500-P ester oil.
