4.4 Start up procedures in cold climate
In winter-season, when operating the pump in cold environment or outdoor especially,
it will be difficult to start up the pump. It is called over-load operation because
of high viscosity of the pump oil at low temperature.
Warm up the pump oil, or repeatedly turn on and turn off the pump (several times on-off
operation) until motor starts rotation.
In the case of the pump stoppage after several second operating, continuous operating
will be possible by opening the pump vent valve. After warming up the pump, close
the pump vent valve, and operate normally.
4.5 Set up oil mist trap (option)
Oil mist trap OMT-050A for GC-25Sa, 50Sa can be equipped for trapping oil mist out
of the pump. After eliminating the standard exhaust pipe, equip the oil mist trap
to the exhaust port. This can reduce oil mists and exhausting noise.
Read the instruction manual of OMT-050A in detail.
4.6 Restriction in an operation of the oil mist trap (option)
When using oil mist trap, the following items should be restricted in an operation.
When the filter clogged with oil, change the filter.
The maximum pressure inside this pump is 0.03MPa(GAUGE).
For pressure reading excess 0.03MPa(GAUGE) in exhaust port, change the filter.
Explosion hazard. Keep the operational restriction in setting the oil mist
trap. When the filter clogged with oil, change the filter.
