4.5 Fill the pump with oil
WARNING:
A hydrocarbon-prepared pump must not be used to process oxygen in concentraons
greater than 25% in volume. As there is a risk of re or explosion in the oil-box of the
pump. PFPE-prepared pumps are available: refer to PFPE-prepared RV pumps on page
56.
Fill the pump with oil as described below. Refer to Lubricaon data on page 20 for the
recommended oil. Refer to Figure: The RV pump for the item numbers in brackets.
1.
Remove one of the oil ller-plugs (6).
2.
Pour oil into the pump unl the oil-level just reaches the MAX mark on the bezel at
the top of the sight-glass (8). If the oil-level goes above the MAX mark, remove the
drain-plug (9) and drain the excess oil from the pump.
3.
Aer a few minutes, recheck the oil-level. If the oil-level is now below the MAX
mark, pour more oil into the pump.
4.
Ret the oil ller-plug. Tighten the plug rmly by hand. Do not overghten.
4.6 Electrical installaon: single-phase pumps
4.6.1 Check and congure the motor
CAUTION:
Ensure that the motor is correctly congured for the local electrical supply. If the
pump is operated when the motor is not correctly congured for the electrical supply,
the motor will be damaged.
Refer to Figure: Motor voltage conguraon: single-phase pumps for the item numbers
in brackets.
Ensure that the voltage shown on the voltage selector switch (3) in the motor‑cover
corresponds with the local electrical supply voltage. If it does not, change the
conguraon of the pump‑motor to match the local electrical supply voltage; use the
following procedure.
1.
Undo the two retaining screws (6) securing the voltage selector switch cover (5).
2.
Remove the voltage selector switch cover (5) and toggle the voltage selector
switch (3) into the alternate posion.
3.
Invert the voltage selector switch cover (5) and ret over the voltage selector
switch (3).
4.
Ret the two retaining screws (6).
