Read this manual and become familiar with the specifications of this
machine prior to use.
Before operating, be sure the power supply conversion switch is set to
the appropriate voltage (110V or 220V) for the power source being used. Be
sure the Power switch is set to the “OFF” position before plugging into power
supply.
The QS5’s motor is equipped with an automatically resetting thermal
overload switch. If the switch is tripped, the motor can restart without any
warning when the motor has cooled.
Wear appropriate safety apparel such as gloves, eye protection and foot
protection when working on refrigeration systems.
Disconnect power before moving or servicing the INFICON QS5.
Improper use or connections may cause electrical shock hazards. Be sure that
all associated devices are properly grounded before energizing circuits.
Use care when touching the pump, as certain components may be hot.
To reduce the risk of fire, extension cords should not be used with this
device as the wiring can overheat under conditions of high current draw. If an
extension cord is absolutely necessary, its length should be as short as
possible and it should contain size 16 AWG or larger wiring.
