ALWAYS, when possible, reduce the number of
transitions and turns. If a long duct run is required,
increase duct size from 6” to 7” or 8”.
If turns or transitions are required: Install as far
away from duct opening and as far apart between
the two transitions as possible.
Minimum mount height between range top to hood
bottom should be no less than 26”.
Maximum mount height should be no higher than
34”.
It is important to install the hood at the proper
mounting height. Hoods mounted too low could

Troubleshooting
TROUBLESHOOTING PROCEDURES FOR ZRO
Issue Cause What to do
After installation,
the unit doesn’t
work.
1. The power source is not turned ON. 1. Make sure the circuit breaker and the unit’s
power is ON.
2. The power line and the cable locking connector
is not connecting properly. 2. Check the power connection with the unit is connected properly.
3. The switch board or control board wirings are
disconnected. 3. Make sure the wirings at the switch board and control board are connected properly.

Light works, but
blower is not
turning.
1. The blower is defective, possibly seized. 1. Change the blower.
2. The thermally protected system detects if the
blower is too hot to operate and shuts the blower
down.
2. The blower will function properly after the
thermally protected system cool down.
3. Damaged capacitor. 3. Change the capacitor.
4. The switch board or control board is defective. 4. Change defective part.
The unit is
vibrating. 1. The blower is not secured in place. 1. Tighten the blower in place.
2. Damaged blower wheel. 2. Replace the blower.
3. The hood is not secured in place. 3. Check the installation of the hood.
The blower is

may disrupt switch functions.
The hood is
not venting out
properly.
1. The hood might be hanging to high from the
cook top. 1. Adjust the distance between the cook top and the bottom of the hood within 26” and 34”
range.
2. The wind from the opened windows or opened
doors in the surrounding area are affecting the
ventilation of the hood.
2. Close all the windows and doors to eliminate

3. Blockage in the duct opening or ductwork. 3. Remove all the blocking from the duct work or
duct opening.
4. The direction of duct opening is against the wind. 4. Adjust the duct opening direction.
5. Using the wrong size of ducting. 5. Change the ducting to at least 6” or higher.

Some local codes limit the maximum amount of CFM a range hood can move. ACT allows you to
control the maximum blower CFM of hoods with of select Zephyr Ventilation range hoods without the
need for expensive make up air kits. ACT enables the installer to easily set the maximum blower speed

If 5 LEDs illuminate = defualt max. CFM, if 4 LEDs illuminate = max. 390 CFM, and if 3 LEDs illuminate
= max. 290 CFM. When ACT is enabled, the number of blower speeds will be reduced. 390 CFM = max.
3 speeds and 290 CFM = max. 2 speeds. There should also be a foil label located inside the hood body
near the wiring diagram that indicates the blower CFM.
