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.

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.

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.
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 product’s 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.
