COATS 1055 Balancer - Manual (Page 11)

Connect to Power
Your factory trained COATS ® Service Technician should do the
final check to verify the power installation before connecting the
balancer to a power supply. Failure due to improper power con-
nection will void the warranty.
Connect the balancer to an appropriate electrical receptacle.
Refer to Figure 8 and 9, as well as Electrical Requirements on
page 1.
Note: If pedestrian or equipment traffic might damage the
standard power cord, power outlets must be enclosed in a race-
way on the floor or in an overhead drop.
Note: Electric outlets must be solidly connected. There should
be less than 1 Ω electrical resistance between the ground pin
and earth ground. The installer or electrical inspector must ver-
ify the outlet installation before connecting the balancer. Failure
due to improper power connection will void the warranty.
Note: The green wire in the cord is the grounding wire. Never
connect the green wire to a live terminal.
Initial Testing
This should be performed by your factory trained COATS ®
Service Technician.
1. If the circuit breaker for the balancer outlet is off, turn it on
now. Turn the balancer ON/OFF switch to ON.
Remember: To maintain the proper operating temperature for
the balancer, the unit should be left on all day.
2. The displays will show zeros when the unit is first turned
on. Press any key to continue.
3. Verify that the fan is running by placing your hand between
the arbor faceplate and the motor housing. You should feel air
coming out from around the motor housing. Do not operate the
balancer if airflow is not present when the balancer is on.
4. Lower the hood and press START. The arbor faceplate
should spin in the direction indicated by the label at the outer
edge of the motor cover (clockwise when viewed straight on).
If the faceplate spins counterclockwise, turn the balancer off,
turn the circuit breaker off, and disconnect the balancer plug.
Swap two of the hot wires connected to the receptacle.
Reconnect the balancer to the receptacle, turn the circuit
breaker on, then turn the balancer on. Lower the hood and press
START and recheck the direction of the spin. The faceplate
should now be spinning in a clockwise direction.
Note: Single-phase balancers will also spin in a clockwise
direction.
Note: Disregard a short spin cycle with HUB displayed on the
control panel during this initial testing.
5. Raise the hood during a spin cycle to verify that the hood
interlock system is functioning properly.
