reflector plate, repeat the above steps until the oil level is at the top of the reflector plate.
4.
Reinstall the oil filler plug.
3.4.2 Shaft seal oil reservoir
WARNING
Ensure that the correct vented filler plug is reinstalled in the shaft seal oil
reservoir. If using a non-vented plug, the oil reservoir will be pressurized,
and the oil level sight glass may be broken.
For the oil level of the shaft seal oil reservoir, we recommend the oil level as shown in
Figure 3. As long as the oil level is above the bottom of the reflector plate, the user can
operate the pump. The oil level of the shaft seal must not be lower than the bottom of the
reflector plate. Otherwise, the pump may be damaged.
The steps are as follows:
1. Unscrew the vented oil filler plug (See Fig.2).
2. Filling the pump oil to the recommended oil level is at the top of the shaft seal reflector
plate (See Fig.3).
3. Reinstall the vented oil filler plug.
3.4.3 Gear cover
Use the same oil that was used to fill the motor side cover and shaft seal oil reservoir.
1. Unscrew the oil filler plug (See Fig.2).
2. Filling the pump oil to the recommended oil level is at the middle of the gear cover oil
level (See Fig.3).
3. Reinstall the oil filler plug.
3.5 Electric connection
3.5.1 Power supply
The motor is configured for "high pressure" operation (380 V and above). The motor itself
does not have a protective device. We recommend that you install a protective device
(overload, leakage circuit breaker, etc.).
WARNING
Ensure that the electric installation of the pump conforms with local and
national safety requirements. It must be connected to a suitably fused and
protected electrical supply with a suitable earth point.
