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.

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.,
