Operation
To guarantee reliability and high level of quality, each
pump is subjected to a rigorous testing and suitable
preliminary running in before it leaves the factory.
Constant performance and long operating life are assured
by strictly observing the following procedures:
Pump start
Before the first initial run, it is mandatory to:
1. fill the pump with the provided oil (see section "filling
of oil").
2. Before subsequent start-ups, always check the oil level
before starting the pump. If necessary, top-up or
replace the oil.
3. before connecting the pump to the system to be
evacuated, check that there is no pressure inside. In
case of connecting the pump with a pressurized
system, the vacuum gauge may break. The vacuum
gauge measures negatives pressures and get collapsed
with positive pressures. Warranty is void if the pump is
connected to a positive pressure.
4. connect the pump to the system to be evacuated by
the necessary equipment (quality hoses, quality
manifolds,etc). The evacuation quality will be directly
related to the way of conecction and to the equipment
quality.
In case of malfunctioning, stop the pump and call the
Service- After-Sales.
Pump stop
As the mixture of incompatible lubricants (pump oil and
compressor oil) can lead to pump failure, installing a non-
return solenoid valve at the suction connection is required
(provided). In case of frequent on-off cycling, do not stop
the pump but shut-off at the charging hose or manifold
instead.
