4.5 Fill the pump with oil
WARNING:
A hydrocarbon-prepared pump must not be used to process oxygen in concentrations
greater than 25% in volume. As there is a risk of fire or explosion in the oil-box of the
pump. PFPE-prepared pumps are available: refer to
56.
Fill the pump with oil as described below. Refer to
on page 20 for the
recommended oil. Refer to
for the item numbers in brackets.
1.
Remove one of the oil filler-plugs (6).
2.
Pour oil into the pump until 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.
After a few minutes, recheck the oil-level. If the oil-level is now below the MAX
mark, pour more oil into the pump.
4.
Refit the oil filler-plug. Tighten the plug firmly by hand. Do not overtighten.
4.6 Electrical installation: single-phase pumps
4.6.1 Check and configure the motor
CAUTION:
Ensure that the motor is correctly configured for the local electrical supply. If the
pump is operated when the motor is not correctly configured for the electrical supply,
the motor will be damaged.
Refer to
Figure: Motor voltage configuration: 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
configuration 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 position.
3.
Invert the voltage selector switch cover (5) and refit over the voltage selector
switch (3).
4.
Refit the two retaining screws (6).
