Installation
Blower may be lifted manually or utilizing lifting equipment based on the instructions below:
WARNING: Danger from lifting heavy loads. Manual handling of the unit is only permitted within the following limits:
• max. 66 lbs (30 kg) for men
• max. 22 lbs (10 kg) for women
• mas. 11 lbs (5 kg) for pregnant women
For the weight of the blower, see Mechanical Data section of this manual. All blowers heavier than the maximums stated above
must be lifted using lifting equipment.
1. The blower is ready to connect upon delivery.
2. Install the blower on a level, stable operating surface and use the optional isolation pads to reduce noise and vibration. Attach
the included loose muffler if necessary.
3. Have a qualified electrician configure the motor to your incoming voltage as noted in the“Motor Wiring”section of the
manual. Refer to the nameplate on the motor for the correct power supply requirements.
4. To ensure sufficient cooling of the blower, it is absolutely necessary that the required minimum distances to the fan guard and
the face of the blower cover be maintained. See “Mechanical Data”for minimum distances. Ventilation screens and openings
must remain clear. Discharge air of other units may not be directly sucked in again.
5. The blower is suitable for installation within the following ambient conditions: dusty or damp environment, in buildings,
in the open (though only if protected from intense sunlight exposure. The blower may be installed within the following
conditions: on level surfaces, and at a maximum elevation of 1000 ft. above sea level. (For higher altitudes, contact Republic
Manufacturing at 800-847-0380.)
6. Blower may be installed in any vertical/horizontal axis position with one exception: vertically with the blower face pointing
upward.
7. From the motor side of the blower, verify the blower is rotating in the direction indicated by the arrow on the motor. (The
motor side is marked with an arrow on most models.) Proper rotation can also be checked by the air flow at the inlet and
outlet ports. On blowers powered by a 3 phase motor, change the connection of any two (2) wires to reverse blower rotation if
needed.
Plumbing & Accessories
1. Remove any foreign material (e.g. burrs, chips, welding drops, pipe cuttings, excess sealant, etc.) from plumbing.
2. Verify the motor is securely mounted and proper blower rotation before connecting to plumbing. The inlet and outlet port are
not designed to support the plumbing without proper supporting elements.
3. Remove safety rubber plugs from the inlet and outlet ports.
4. Connect the plumbing with properly sized ttings.
5. Use a relief valve to discharge excess air beyond the preset level on pressure applications. Use a vacuum relief valve to draw in
excess air when preset vacuum level is achieved.
6. Install an intake lter to prevent foreign material from entering the blower. In applications where there is high humidity or
liquids being used in the process, install a moisture separator with a drain valve.
7. Install two (2) gauges - one before and one after the lter - to monitor dierential air ow through the lter element. As
lters become clogged, performance eciency will be reduced. Filters should be checked periodically and replaced when
necessary. The recommended check valves provide minimal pressure drop, positive sealing, and are resistant to the high
discharge temperatures of the blowers.
8. Recommended piping should be, at minimum, the same size as the inlet and outlet ports on pressure systems.
WARNING: Exhaust air temperature increases signicantly above 65”WC (162 mbar). Discharged air is typically too hot for
most plastic piping, therefore metal piping is recommended. This piping must be guarded and marked
“DANGERHOTDONOT TOUCH”.
9. Metal piping is recommended for the rst 5 ft. (1.5 m) to 8 ft. (2.4 m) from the blower on pressure systems. Elbows increase
friction, so elbows should be minimized to decrease friction loss.
10. Pressure or relief valves should be installed in a “T” that is at least one (1) pipe size larger than the port diameter.
