• Electrical work should be performed by a qualified
electrician. Otherwise, personal injury or property
damage may result.
• Do not install the pump in a place where the pump
can get wet. Avoid using wet gas, or internal con-
densation will build up and consequently result in
the short lives of the valve and diaphragm.
• Do not use the pump in a dusty place. Be sure
to provide the inlet with a filter to prevent foreign
matters from getting into the pump. Otherwise, the
pump performance may reduce or the lives of the
valve and diaphragm remarkably shorten.
• Do not install the pump in a corrosive or flamma-
ble gas atmosphere. Keep good ventilation in a
working area. Ambient temperature should not fall
below 5°C or exceed 40°C. Observe the allowable
gas temperature range of 0 and 40°C.
• If the compressed air (higher pressure than atmos-
pheric pressure) is transferred to the pump, sharp
deterioration to the lives of the valve, diaphragm
and bearing may result. Always keep atmospheric
or lower pressure in the suction line.
