Operation
* Inserting fingers or objects into the motor inlet may result in electric shock, injury, or fire.
* Operating the pump with the discharge outlet blocked, or with a device which prevents
passage of gas to the discharge outlet, may result in rupture of the pump. The internal
pressure of the pump rises and the pump body may rupture and the motor become
overloaded.
This pump is not designed to be pressure-resistant. The internal pressure of the pump is
limited to 30 kPa (gauge pressure).
Maintenance and Repair
* The pump should be dismantled or repaired only by a repair technician trained by the
manufacturer.
* To prevent ingestion of microscopic particles resulting from wear of components, use a
dust mask and gloves when replacing diaphragms, and valves.
Installation
* To prevent back injuries, always use at least two people when lifting and moving the
pump.
* Microscopic particles resulting from wear of components are discharged from the outlet
and contaminate the room. If necessary, connect a pipe from the discharge outlet to the
outside of the building.
* The fine clearances used in this pump require that the following conditions be satisfied
during storage, installation, and operation.
1. Ambient temperature of 7°C ~40°C and maximum relative humidity of 85% during
operation.
2. Other conditions for storage and operation.
a) Level floor of sufficient strength.
b) No condensation
c) Dust-free environment
d) Well ventilated
e) Environment free of corrosive or explosive gas.
f) Not subject to direct sunlight.
g) No danger of fire.
h) Maximum ambient temperature of 40°C during assembly of pump.
Operation
* Touching rotating components (eg motor, main shaft, axial joints) while the pump is in
operation may result in injury.
* Touching the motor while the pump is in operation or while it is still hot immediately after
having been switched off may result in burns.
* Do not insert fingers or objects into, or peer into, the inlet or outlet during operation.
Maintenance and Repair
* If the pump ceases operation, turn power OFF (set switch to O) immediately to prevent
accidents, remove the power cord from the wall outlet, and contact your dealer or the
manufacturer for inspection and repair.
