Connection To The Machine; Discharge Air Pipiline Installation; Electric Connection - Agilent Technologies PHV K Series Operating And Maintenance Instructions Manual

5.2 Connection to the machine

Inlet and discharge ports should be connected to the system using clamps according to International Stand-
ards.
Make sure the pipes and the flanges are clean.
Use pipes as much as short and thick as possible, having at least the same diameter as the one of their ports.
Max. pressure of the oil is 1,5 Kg/cm
Make sure the pipes and the flanges are vacuum tight, i.e. there isn't any vacuum leakage.
5.3 Discharge air pipeline installation
When required, it is possible to pipe the pump discharge air to other rooms, or outside.
Use pipes with the same diameter as the tank discharge port with a maximum length of 15 m.
For longer pipes increase pipe diameter.
Pipe weights must not rest on the pump.
In the final length use flexible pipes or pipe fittings
WARNNG:
this pipe must be descending, to avoid the condensate going back to the tank.
Do not connect ball valves to this pipeline.

5.4 ELECTRIC CONNECTION

The control panel and electric connections must be carried out by skilled personnel and conform to the EN
60204-1 rules or other local regulations in the Country of use.
The electric equipment must comply with EN 61000-6-4 and EN 61000-6-2 standard concerning electromag-
netic compatibility, emission standard and immunity for industrial environments.
Check the main voltage and frequency in use to correspond to the data stamped on the motor name plate.
The electric motor must be protected against overload. The full load amperage value on the motor name plate
must be considered when sizing the electrical components and motor protection against overloading.
Make sure the grounding is correctly done.
Carry out the electric connection following the diagram shown on the motor terminal box.
Check direction of rotation of the motor:
1. Open the inlet and discharge ports.
2. Lay the transport protection caps on the inlet port.
3. Switch the pump on for 2 to 3 seconds checking that the plastic cap get tight on the inlet port.
