Start Up
Operate blower for an hour and then check:
1. Ambient temperature – Check room and discharge
air temperatures. Increased room temperatures
may require stronger ventilation especially for larger
blowers. Exhaust air should not exceed 215ºF
(102ºC) for all blowers less than 3.5 Hp. Exhaust air
should not exceed 275ºF (135ºC) for all blowers
above 3.5 Hp.
2. Working pressure and vacuum values – Adjust
relief valve pressure or vacuum setting, if needed.
3. Motor current – Check that supply current matches
recommended current rating on product nameplate.
4. Electrical overload cutout – Check that current
matches rating on product nameplate.
It is your responsibility to operate this product at
recommended pressures or vacuum duties and room
ambient temperatures. Do not operate R4P or larger
size blowers without air flowing through the blower. Do
not throttle discharge or suction pipe to reducer
capacity. Throttle will increase differential pressure
causing increasing power absorption and working
temperatures.
OPERATION
Injury Hazard
Install proper safety guards as needed to prevent
any close contact with blower suction area.
Keep fingers and objects away from openings and
rotating parts.
Product surfaces become very hot during operation,
allow product surfaces to cool before handling.
Air stream from product may contain solid or liquid
material that can result in eye or skin damage,
wear proper eye protection.
Wear hearing protection. Sound level from some
models may exceed 85 dBA.
Failure to follow these instructions can result in
burns, eye injury or other serious injury.
WARNING
If motor fails to start or slows down significantly under
load, shut off and disconnect from power supply. Check
that the voltage is correct for motor and that motor is
turning in the proper direction.
MAINTENANCE
c
WARNING
Electrical Shock Hazard
Disconnect electrical power supply cord before
performing maintenance on this product.
Some motors are thermally protected and will
automatically re-start when protector resets.
If product is hard wired into system, disconnect
electrical power at the circuit breaker or fuse box
before performing maintenance on this product.
Failure to follow these instructions can result in
death, fire or electrical shock.
If the product is supplied with an electric power
chord, protect it from twisting, cuts and abrasion.
When not in use, store in a clean dry place
It is your responsibility to regularly inspect and make
necessary repairs to this product in order to maintain
proper operation. Make sure that pressure and vacuum
is released from product before starting maintenance.
Injury Hazard
Product surfaces become very hot during operation,
allow product surfaces to cool before handling.
Air stream from product may contain solid or liquid
material that can result in eye or skin damage,
wear proper eye protection.
Failure to follow these instructions can result in
burns, eye injury or other serious injury.
WARNING
Check filter elements and noise absorbing foam used in
mufflers and clean motor and blower after first 500
hours of operation. Replace filter elements and
determine how frequently mufflers should be checked
during future operation. This one procedure will help
assure the productʼs performance and service life.
When there is an increase in the differential pressure
across the inlet filter it is beginning to clog with dirt.
Replace the cartridge when the filter will not come
clean.
Small motor bearings (less than 5.5 Hp) never need to
be greased. Larger motor bearings (greater than 5.5
Hp) have alemite grease fittings. Use a grease gun and
apply one or two strokes of Exxon POLYREX® grease
to the fittings to lubricate larger motor bearings.

Check that all external accessories such as relief valves
and gauges are not damaged before re-operating
product.
