Check if unit has been plugged in, make sure that all power
has been turned back on and all electrical wiring are
properly connected.
Blower blade unit might have been mounted too low and
scraping the bottom or jammed. Loosen hex screw on
blade unit and adjust to proper height.
There might have been foreign particles left within the
discharge opening or rocks, leaves, branches, etc. that
might have fell in from old duct work. Disconnect duct work
to inspect and remove any foreign particles.
Unit might not have been secured properly on cabinet. Or
cabinet might need to be further secured into studs on wall.
Our blowers are designed to perform up to 695 cfm. A
properly functioning motor itself should be relatively quiet.
Nevertheless, due to vacuum created by the suction, noise
level up to 5.5 sones will be generated when both blower
unit is turned on at its maximum speed. Employ both
blowers at maximum speed only when needed (heavy pan
frying, wok cooking etc.) Employing low speeds or a single
blower will suffice moderate cooking such as steaming,
broiling etc.
Light bulb might need to be replaced. On some instances,
the fragile bulb could have been damaged during the
shipping process. Simply replace with a 40 or 60W
appliance bulb.
Grease flow will vary by the amount, methods and types of
cooking. If pan-frying is frequent accompanied by
steaming, vapor from steam will liquefy accumulated
grease in its internal housing and flows in the containers.
No grease collected in the residue containers is normal
until the self clean function is completed. Clean blowers
approximately once a month as instructed to avoid
clogging.
Tubes connected to the internal housing might have been
clogged due to lack of cleaning. Or hood might not have
been leveled when installed. Unclog tubes or re-install
hood (refer page 16).
The self clean feature cleans only the internal housing
within the range hood. Remove safety grill to clean in
dishwasher and clean all surface periodically as instructed.
Check duct size used, duct size should be at least 6“ or 3-
1/4 x 10”. Range hood WILL NOT function properly with
the insufficient duct size.
Check if duct is clogged or if damper unit is not opening
properly. A tight mesh on a side wall cap unit might also
cause restriction to the air flow.
