Ductwork
WARNING:
Failure to prevent products of combustion from
being circulated into the occupied space can create
potentially hazardous conditions including carbon
monoxide poisoning that could result in personal
injury or death.
The duct connections must be physically sound and sealed to the
unit’s casing to prevent products of combustion from entering the
occupied space.
The return air and circulating air ductwork must not be connected
to any other heat producing device such as a fireplace insert, stove,
etc. Doing so may result in fire, explosion, personal injury, carbon
monoxide poisoning, or property damage.
Regular Cleaning
CAUTION:
DO NOT make contact with any of the internal
electrical components while cleaning the unit.
• Remove any leaves and grass clippings from the outdoor coil.
Check for and remove any obstructions such as twigs, sticks, etc.
Be careful not to damage the aluminum fins
Air Filters
WARNING:
Never operate the unit without a filter in the return
air system. Dust and lint in the return air can build
up on the internal components, resulting in loss of
efficiency, equipment damage, and possible fire risk.
This unit is not supplied with air filter(s) and has no means for
accommodating internal air filter(s). The installer is responsible for
installing a filtration system into the return air duct of this system.
The filter(s) of this system should be checked monthly.
It is very important to replace or clean the filter(s) installed in the return
air duct of this system. A clogged filter could cause airflow related
problems and reduce the overall efficiency of your unit. Depending
upon which type of filter was installed with your unit, clean (permanent)
or replace (disposable) filter(s) of your system at the beginning of
every heating season, the beginning of every cooling season, and
when an accumulation of dust and dirt are visible on the filter.
IMPORTANT: Replace disposable filter(s) installed in your
system only with the same size dimensional filters that are
being replaced. Clean permanent filter(s) as described by the
manufacturer.

Proper maintenance is most important to achieve the best performance
from the appliance and should be performed by a qualified service
technician at least once a year. Follow the maintenance schedule
and the instructions below for years of safe, trouble free operation.
• Annually inspect the physical support of the unit to ensure that it
is physically sound without sagging, cracks, gaps, etc., around the
base so as to provide a seal between the support and the base.
• Annually inspect the return-air connection to ensure that it is
physically sound and is still sealed to the casing of the unit. Also
inspect the unit, ductwork, and vent system for signs of physical
deterioration.
