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:

You will be killed or seriously injured if you donʼt follow

instructions.

You can be killed or seriously injured if you donʼt 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.

Correct installation is your responsibility.

Make sure you

have the proper installation conditions and that

installation clearances do not block air flow.

Blocking air flow over the product in any way can cause

the product to overheat.

The blower must be installed with the properly sized

inlet filter, gauge and relief valve to protect the product

from dirt and over-heating.

INSTALLATION

Accessories

Install two vacuum gauges, one before and one after

filter, to monitor restriction through filters. As filters

become clogged, performance efficiency will be

reduced. Filters should be checked periodically and

replaced when necessary. See page 7 for installation.
Install a relief valve to avoid changes in pressure or

vacuum that can cause overloading of large blowers.

Install an intake filter with a relief valve to prevent

foreign material from entering blower if blower is used in

a vacuum application in a dirty environment. In

applications where there is high humidity or liquids

being used in the process, install a moisture separator.
See Recommended Accessories on pages 7-9 or

consult your Gast Distributor/Representative for

additional filter and accessories recommendations. Do

Not install check valves that close with a strong spring.

The recommended check valves (page 7) provide

minimal pressure drop, positive sealing and are

resistant to the high discharge temperatures of large

blowers.

WARNING

DANGER

c

Disconnect electrical power at the circuit breaker

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

contact with water or other liquids.
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.

WARNING

Electrical Shock Hazard

Plumbing

Remove any foreign material (burrs, chips, welding

drops, slag, pipe cuttings, excess sealant, sand or lime)

from plumbing.

Check motor mounting and rotation before connecting

to plumbing. Inlet and outlet ports are not designed to

support plumbing.
Remove plugs from the IN and OUT ports. Use a small

amount of pipe thread lubricant when connecting

plumbing to protect the aluminum blower threads.

Connect with pipe and fittings that are the same size or

larger than the productʼs threaded ports. When

installing two blowers in parallel, use plumbing that is

two whole pipe sizes larger in diameter than that of the

blower. Be sure to connect the intake and exhaust

plumbing to the correct inlet and outlet ports.
Plumbing to remove the hot discharge air of larger

blowers may be required to help maintain proper room

ambient temperature. Use a relief valve to discharge

excess air into the atmosphere. If the blower will be

operated at 125mbar (50” H

2

O) or higher, metal pipe is

required for hot exhaust air.

Mounting

The single impeller blower should be oriented with the

shaft in a horizontal position, unless the modelʼs product

features state otherwise. The dual impeller models must

be mounted with the shaft in a horizontal position.

Mounting the product to a stable, rigid operating surface

and using shock mounts will reduce noise and vibration.

Rotation

From the motor side of the blower, check that the blower is

rotating clockwise. (The motor side is marked with an

arrow on most models.) Proper rotation can also be

checked by the air flow at the IN and OUT ports. On

blowers powered by a 3-phase motor, incorrectly

connecting any two power lines can reverse direction.

Motor Installation

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.
