This is the hazard alert symbol: When you
see this symbol be aware that personal injury or
property damage is possible. The hazard is
explained in the text following the symbol.
Read the information carefully
before proceeding.
The following is an explanation of the three
different types of hazards:
DANGER Severe personal injury or death
will occur if hazard is ignored.
WARNING Severe personal injury or death
can occur if hazard is ignored.
CAUTION Minor injury or property damage
can occur if hazard is ignored.
GENERAL SAFETY GUIDELINES
FOR THIS PRODUCT
WARNING
•Poor wiring can result in electric shock. Wiring
must conform to all required safety codes and be
installed by a qualified person. Refer to wiring
diagram on page 8.
•Always disconnect power source before servicing.
CAUTION
•Required ambient temperature is -10 O F to 150 O F.
Operation at temperatures outside this range, will
reduce the life of the pump.
•Do not block the flow of cooling air over the pump
in any way.
•This unit is designed to pump gases only.
Ingestion of dirt, metal, water, or petroleum-based
contaminants will reduce the life of the pump.
Lower atmospheric pressure at high altitudes lowers perfor-
mance. Consult a Gast distributor for details.
Never lubricate this oil-less pump. The sealed bearings are
grease-packed. Introducing petroleum based or hydrocarbon
products will reduce the service life of the diaphragm and valve.
Ensure that nothing will interfere with the movement of the
eccentric. While not dangerous, the eccentric must move freely
to allow the pump to operated properly.
MOUNTING
To reduce noise and vibration, use Velcro or a vibration-isolated
mounting surface.
PLUMBING
To prevent air flow restriction, use an elastic hose of the same
size as the hose port. These ports are not designed to support
plumbing.
FILTERS
Avoid unfiltered operation in an environment where there is
visible airborne particulate material. Use a suitable filter to
avoid ingesting dirt/metal or other foreign material into the
pump.
WIRING
Ensure that the supply voltage agrees with the pump operating
voltage. Remove power to the pump if the motor fails to start or
stops under load. Warming the pump to a minimum of -10 F in
extremely cold weather will ease starting and extend the life of
the pump.
OPERATION
General recommendations for operation:
Avoid operating the pump at temperatures less than -10
o F or
greater than 150 o F.
Draw through the pump only those substances which do not
react with PPS or EPDM (diaphragm and valve material).
Avoid unfiltered operation in an environment where there is
visible airborne particulate matter.
Avoid ingesting dirt into the pump.
Following these basic recommendations will avoid damage to
the pump and may extend its operating life.
