www.zephyronline.com
DUCTING
A minimum of 6” round duct must be used to
maintain maximum air ow efciency.
Always use rigid type metal ducts only. Flexible
ducts could restrict air ow by up to 50%.
Use calculation worksheet to compute total duct
work (Page 5).
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
result in heat damage and re hazard; while hoods
mounted too high will be hard to reach and will
loose performance and efciency.
If available, also refer to range manufacturer’s
height clearance requirements and recommended
hood mounting height above range. Always check
your local codes for any differences.
Duct cover extension kit available for ceiling
heights up to 12 feet. Turn to page 22 for part
number and ordering information.

Installation – Mounting the Hood
FIG. A

13
Ductless recirculation is intended for applications where an exhaust duct work is not possible to be installed.
When converted, the hood functions as a recirculating hood rather than an exhaust hood. Fumes and exhaust
from cooking are drawn and ltered by a set of optional charcoal lters. The air is then puried and re-
circulated back within the home.
We recommend to ALWAYS exhaust air outside of the home by employing existing or installing new duct
work, if possible. The hood is most effective and efcient as an exhaust hood. Only when the exhaust option
is not possible should you recourse to converting the hood into a recirculating hood.
When converted to be a recirculating hood, a set of charcoal lters are required on top of its standard Metal
Filter set. Order according to its part number below. The standard mesh lters are intended to capture residue
from cooking and the optional charcoal lters help to purify fumes exhausted from cooking for recirculation.
RECIRCULATING KIT (REQUIRED IF NO DUCTING IS USED)
Kit includes charcoal lters, charcoal lter brackets and air diverter plate.

1. Purchase recirculating kit per the part number above
2. Secure air diverter plate to wall below duct cover bracket. Run 6”
ducting from top of hood and secure to air diverter plate. (FIG. B)
3. ZAN: Remove aluminum mesh lters from hood. Secure charcoal lters
to back side of aluminum mesh lter by 3 brackets. (FIG. B.2)
3. ZSA, ZRV, ZRO: Remove aluminum mesh lters from hood. Secure
charcoal lter brackets to the hood body behind each mesh lters using
the screws included in the recirculating kit. Clip charcoal lters onto
each charcoal lter bracket. (FIG. B.1)
4. Re-Install mesh lters. For more details refer to manual included
with recirculating kit.
5. Charcoal lters must be replaced after every 120 hours of use (or
approximately every 3 to 4 months based on an average of 1 - 2 hrs. of
daily cooking time).

Airow Control Technology (ACT)
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.
ACT enables the installer to easily set the maximum blower speed to one of two most commonly specied CFM
levels; 390 or 290 CFM. The usage of ACT may not be necessary for your installation. Please check your local codes
for CFM restrictions.
By default the maximum blower CFM is set to 600 for ZAN, ZRV and ZRO.
By default the maximum blower CFM is set to 685 for ZSA.
To enable ACT
1. Before hood installation, gain access to PC board by following the steps shown in FIG. C.
2. Change plastic jumper positioning as shown in FIG. D 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.
