Cypress Use, Care, and Installation Guide
ZEPHYRONLINE.COM
Installation Instructions
Mounting Height, Clearance, & Ducting
36” 30” min.
36” max.
A minimum of 10” round duct is recommended to
maintain maximum air flow eciency.
Always use rigid type metal ducts only. Flexible
ducts could restrict air flow by up to 50%.
Also use the ducting calculation sheet (on page
8) to compute total available duct run when using
elbows, transitions and caps.
ALWAYS, when possible, reduce the number or
transitions and turns. If long duct run is required,
increase duct size.
If turns or transitions are required; install as far
away from hood duct output and as far apart,
between the two as possible.
Minimum mount height between range top to hood
bottom should be no less than 30”.
Maximum mount height should be no higher than
36”.
It is important to install the hood at the proper
mounting height. Hoods mounted too low could
result in heat damage and fire hazard; while hoods
mounted too high will be hard to reach and will lose
its performance and eciency.
If available, also refer range manufacturer’s height clearance requirements and recommended hood
mounting height above range. Always check your local codes for any dierences.
For shipment and installation damages:
►Please fully inspect unit for damage before installation.
►If the unit is damaged in shipment, return the unit to the store in which it was bought for repair or
replacement.
►If the unit is damaged by the customer, repair or replacement is the responsibility of the customer.
►If the unit is damaged by the installer (if other than the customer), repair of replacement must be
made by arrangement between customer and installer.

Ducting Options
►Use single wall rigid metal ductwork only.
►Fasten all connections with sheet metal screws and tape all joints w/ certified Silver Tape or Duct
Tape.
Fire Hazard: NEVER exhaust air or terminate ductwork into
spaces between walls, crawl spaces, ceilings, attics, or garages.
All exhaust must be ducted to the outside, unless using the
recirculating option.

Maintenance
Hood & Filter Cleaning
Surface Maintenance
►Do not use corrosive detergents, abrasive detergents or oven cleaners.
►Do not use any product containing chlorine bleach or any product containing chloride.
►Do not use steel wool or abrasive scrubbing pads which will scratch and damage surface.
Cleaning Stainless Steel
Clean periodically with warm soapy water and clean cotton cloth or micro fiber cloth. Always rub
in the direction of the stainless steel grain. To remove heavier grease build up use a liquid degreaser
detergent.
After cleaning use a non-abrasive stainless steel polish/cleaners, to polish and bu out the stainless
luster and grain. Always scrub lightly, with clean cotton cloth or micro fiber cloth and bu in the
direction of the stainless steel grain.
Cleaning the Pro Bae Filters
The stainless steel pro baffle filters are intended to trap residue and grease from cooking. Although
the filters should never need replacing, they are required to be cleaned every 30 days or more often
depending on cooking habits.
Filters may be placed in dishwasher at low heat or soaked in hot soapy water Dry filters and re-install
before using hood.
If this hood is installed in a salt water area (e.g. coast), rinse all
surfaces once a week with clear water even if the hood is not
used. Wipe and dry completely after rinsing.
