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

SURFACE MAINTENANCE:
Clean the hood surface periodically with hot soapy water and clean cotton cloth. Do not use corrosive or
abrasive detergent or steel wool/scouring pads which will scratch and damage surface.
For heavier soil use liquid degreaser.
After cleaning it is recommended that you use non-abrasive stainless steel polish/cleaners, to polish and
buff out the stainless luster and grain.Always scrub lightly, with clean cotton cloth, and with the grain.
Do not use any product containing chlorine bleach. Do not use “orange” cleaners.

Troubleshooting
TROUBLESHOOTING PROCEDURES
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.
4. The switch board or control board is defective. 4. Change the switch board or control board.
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 speed levels
of the blower
sound the same.
1. Using the wrong size or type of ducting. 1. Change the duct size to at least 6” round or
higher and change the duct type to rigid metal
UDWKHUWKDQÀH[DEOH
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
working, but the
lights are not.
1. Defective LED bulb. 1. Change the LED bulb.
2. The LED wire connection to the control board is
disconnected. 2. Check the LED wire connection at the control board.
3. The LED bulb connector is disconnected. 3. Check the LED bulb connector.
The unit turns on
by itself. 1. A spot light or kitchen lamp is shining directly onto the switch controls. 1. The switch controls are light sensative. A direct light source onto the switch controls
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
WKHRXWVLGHZLQGÀRZ
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.

ACT Conversion
ALUÀRZ&RQWURO7HFKQRORJ\$&7
Some local codes limit the maximum amount of CFM a range hood can move. ACT allows you to control the
maximum blower CFM of select Zephyr Ventilation range hoods without the need for expensive make up air kits.

for CFM restrictions.
By default the maximum blower CFM is set to 600.
To enable ACT
1. Before hood installation, gain access to PC board by following the steps shown in FIG. J.
2. Change plastic jumper positioning as shown in FIG. K to set the desired maximum blower CFM.
3. Re-install PC board & continue with hood installation.
4. Remove the appropriate foil CFM sticker included with the hood literature and place inside the hood body below
the wiring diagram or in another clearly visible location.
NOTE: After re-positioning the jumper and powering on the hood, the CFM cannot be changed again.
To verify if your installer enabled ACT
With hood off, press and hold the power button for three seconds. 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. 4 speeds and 290 CFM =
max. 3 speeds.
There should also be a foil label located inside the hood body near the wiring diagram that indicates the blower CFM.
CAUTION:
Hood must be disconnected from main power prior to performing the
conversion instructions listed below. Failure to do so could result in
personal injury or damage to the product.
