Installation - Idex Gast DOA Series Operation & Maintenance Manual

Your safety and the safety of others
is extremely important.
We have provided many important safety messages
in this manual and on your product. Always read
and obey all safety messages.
This is the safety alert symbol. This symbol
alerts you to hazards that can kill or hurt you and
others. The safety alert symbol and the words
"DANGER" and "WARNING" will precede all safety
messages. These words mean:
DANGER
You will be killed or seriously injured if you don't
follow instructions.
WARNING
You can be killed or seriously injured if you don't
follow instructions.
All safety messages will identify the hazard, tell you
how to reduce the chance of injury, and tell you
what can happen if the safety instructions are not
followed.

or fuse box before installing this product.
Install this product where it will not come into

Install this product where it will be weather
protected.
Electrically ground this product.
Failure to follow these instructions can result in
death, fire or electrical shock.

Plumbing
Remove plugs from the IN and OUT ports. Be sure to
connect the intake and exhaust plumbing to the correct
inlet and outlet ports. Ports will not support the
weight of the plumbing.
Accessories
Filters and mufflers are supplied with some models.
These should be checked periodically and replaced
when necessary. An optional liquid trap should be
installed between the line and the intake filter if this unit
will be operated in a wet application. Please consult
your Gast Distributor/Representative for additional filter
recommendations.
Check valves may be required to prevent back
streaming through the pump.
Motor Control
It is your responsibility to contact a qualified
electrician and assure that the electrical installation is
adequate and in conformance with all national and
local codes and ordinances.
Select fuses, motor protective switches or thermal
protective switches to provide protection. Fuses act as
short circuit protection for the motor, not as protection
against overload. Incoming line fuses must be able to
withstand the motor's starting current. Motor starters with
thermal magnetic overload or circuit breakers protect
motor from overload or reduced voltage conditions. If
additional information is required, please consult your
Gast Distributor/Representative.
The wiring diagram supplied with the product provides
required electrical information. Check that power source
is correct to properly operate the dual-voltage motors.
Electrical Connection
WARNING
Electrical Shock Hazard

Do not modify the plug provided. If it will not
fit the outlet, have the proper outlet installed
by a qualified electrician.
If repair or replacement of the cord or plug is
necessary, do not connect the grounding wire
to either flat blade terminal. The wire with
insulation that is green with or without yellow
stripes is the grounding wire.
Check the condition of the power supply wiring.
Do not permanently connect this product to
wiring that is not in good condition or is
inadequate for the requirements of this product.
Failure to follow these instructions can result in
death, fire or electrical shock.
