Column Mounted Unit
Units are factory wired for the voltage requirement
indicated to uaS by the customer. the electrical
box has knockouts. Therefore, whatever electrical
connectors are standard in your plant may be used
for the power line into the unit.
the power switch for operating the unit and any fused
disconnect switch should be supplied by the customer
and located remotely (not supplied as part of the
Smog-Hog).

7. MOTOR/BLOWER CHECKOUT

for proper airflow, the blower should be operating in
the correct direction. if the blower is operating in the
reverse direction, air will move in the proper direction,
but at significantly reduced rates. refer to figure 3 for
access to blower compartment. to check rotation:
1. Place SHn unit off line.
2. remove or open blower panel to the SHn unit to
observe rotation.
3. Place SHn unit on line for less than one minute.
4. Place SHn unit off line.
5. as the blower pulley slows down, observe the
direction of rotation.
6. note directional arrow located on the blower housing.

WARNING
!
Extreme care should be exercised when operating
blowers with motor/drive belts exposed. Loose fitting
clothing can easily be drawn into these moving parts.
7. if blower wheel is not rotating in the correct direction,
disengage main three-phase fused disconnect switch.
WARNING
!
Do not attempt to rewire electrical "live" connections.
8. open power panel and reverse any two of the three
wires at the terminal strip (L1, L2 and L3).
9. engage the fused disconnect and place SHn unit on
line, confirming blower rotation.
When the Smog-Hog is used in a ducted application,
blower speed is increased to compensate for the static
pressure loss of the ducting. after ducting is installed,
and with the unit operating, measure the current flow
to the unit using an amp probe. the ampere reading
should not exceed the FLA rating on the
motor nameplate. If current flow is excessive, reduce
blower speed by adjustment of the variable pitch
sheave on the motor.
CAUTION
!
if the blower is rotating backwards, some air motion
is noticeable. if the blower is rotating correctly, the
access door will be closed by the negative pressure
within the cabinet.
Single-phase units (i.e. 115/1/50-60) are prewired for
proper rotation and line hook-up. Simply connect to
single phase input circuit and unit is ready for operation.
Input to the high voltage power pack should not exceed
130 Volts, 60 Hertz. this is supplied by a power source
or the step-down transformer as shown in the wiring
diagram inside the main electrical junction box on
all units. Refer to Appendix B.
