the first time, remove the manometer and its adapter
(open end wrench width 17 mm) and
pour in the oil as
described below.
Note: Because new oil contains gas, a considerable
degree of foaming can occur during operation with new
oil, and oil could penetrate the oil separator.
- Pour only approx. 350 ml (0.37 quarts) of oil into the
pump (bringing oil level to ”min.” mark, approx.).
- Reinstall the manometer (carefully re-seating the O-
ring) and with inlet line closed, operate the pump for
approx. 5-10 minutes.
- Add approx. 100 ml (0.11 quarts) of oil. As a rule, it
is not necessary to use all of the oil supplied.
Do not
overfill!
• Check the power source and the pump’s rating plate
to be sure that the power source and the equipment
match in voltage, phase, and frequency.
Keep a distance of minimum 8 in (20 cm) between fan and
adjacent equipment or casework.
Use connecting hoses with large diameter and keep them
as short as possible to avoid flow losses. Locate the pump
as closely as possible to the application. Use only hoses
at the inlet and outlet of the pump with an inner diameter
at least as large as the diameter of the pump’s connec-
tions.
Always install outlet tubing descending from the pump to
avoid backflow of condensate towards the pump.
Use a suitable valve (see”Accessories”, pg. 36) to iso-
late the pump from the vacuum application. This is to allow
the pump to warm up before pumping condensable vapors
and to clean the pump after use before it is switched off.
When assembling, ensure
vacuum-tightness. After as-
sembly, check the whole system for leaks.
Secure hose connections at the pump appropriately, e.g.,
