Operation
(6) Ensure that the pump is used within an ambient temperature range of 7
～
40°C.
Use at high temperatures will dramatically reduce the life of the pump.
Install cooling equipment (e.g. a fan) if the pump is to be used at an ambient temperature in
excess of 40°C, and set ambient temperature to 40°C or less.
(7) Ensure that the pump outlet is free of back pressure when the pump is started. Back
pressure at the pump outlet will result in overload on the motor, and may prevent starting.
(8) The overload protector operates when the pump becomes excessively hot. Touching it in this
condition may result in burns.
Maintenance and Repair
(9) The pump is manufactured to accurate clearances, and should not be dismantled or modified
under any circumstances.
(10)Miscellaneous
* Problems (e.g. faults) with the vacuum pump shall be resolved by consultation between
the two parties.
