4. Operation
4.1 Precautions for operation
Only suction for inert gases.
This pump is designed to exhaust only inert gases (air, nitrogen, or argon). It cannot
be used to exhaust other gases (toxic, combustible, corrosive, or explosive gas, or
gas that increases the susceptibility of substances) because such gas may leak from
the pump's main unit or ignite or explode inside the pump.
Do not suction toxic gases with this pump.
If this pump sucks in toxic gas, both the pump's main unit and the lubricant will become
toxic. Keep this in mind during maintenance.
Do not absorb air just after during the operating and a stop at current
opportunity.
Do not use this pump in areas where a hazardous atmosphere may form.
Do not use this pump in areas where a hazardous atmosphere may be formed by an
explosive gas. Otherwise, injury or fire may occur.
Do not block the exhaust outlet port.
Do not operate this pump with equipment attached to the exhaust outlet port side that
blocks the exhaust outlet port or disturbs the flow of gases.
Such operation may cause the pump's internal pressure to rise, causing the casing or
level gauge to rupture, oil leakage, or motor overload. This pump does not have a
pressure-resistant structure. The pump's guaranteed withstand pressure is 0.03
MPaG (0.3 kg/cm
2
G) (gauge reading).
Do not put a thing to less than 1m around the pump.
In operation, the main body of pump and boiler part becomes the high temperature
very much. When less than 1m includes a thing from current opportunity, there
might be a burn by the abnormal overheat, the fire.
During operation, do not touch the pump's main body or piping.
During operation, do not touch the pump's main body or piping during operation
because they reach extremely high temperatures. Touching it may lead to burns.
Confirm that the valves are open.
If the piping located behind the exhaust outlet port has valves, confirm that such valves
are open.
Be sure to feed cooling water to this pump during operation.
Be sure to feed cooling water to this pump during operation.
One hour or more, to feed cooling water to this pump after a stop by all means.
