Unit Maintenance

All Products – Filters and Filter Servicing
All Bard products contain air filters that must be cleaned or replaced on a regular basis.
Keeping air filter(s) clean is the single most important responsibility of the user of the equipment. Each type
of system must be equipped with an air filter(s) in the indoor circulating air system to clean the air, keep the
system itself clean for peak efficiency and capacity and prolong the useful life of the equipment. DO NOT operate
the system without the proper air filters. Filters should be inspected at least monthly and replaced or cleaned
(depending on type) as needed. The useful life of an air filter can vary widely depending upon application and use
of the equipment, and it is critical to monitor filter condition and establish an acceptable maintenance schedule.
Failure to do so will increase operating and repair costs, decrease capacity and efficiency and shorten the service
life of the equipment. A common symptom of a dirty filter in the cooling mode is a freeze-up of the indoor coil. The
air filters used may be a disposable (throwaway) type or may be a cleanable type that can be thoroughly cleaned,
rinsed and reused many times. It is important to make sure that the correct filter size and type for your system is
always used. If there is any question as to acceptable filter size or type, review the installation instructions for the
specific equipment involved, if available. Otherwise, consult with your installing dealer or service company. Most
equipment can have the filters inspected and serviced by the user with no problems. In some instances, because of
equipment design or specific installation conditions, it may be necessary to have this procedure done by a qualified
service company. Have your installer or service company show you where the filter(s) are and demonstrate the service
procedure or make arrangements for them to provide this service on an as-needed basis.

Outdoor Unit Wall Mount Room Air Filters

Wall mount filters are normally accessed from the outside of the building. Bard does offer a return air grille with a
filter frame built-in for indoor filter access. The return air filter grille is not acceptable as the only source of filtration
if vent options are installed in the wall mount unit.
The product installation instructions contain additional information regarding unit maintenance. This
information may be accessed at www.bardhvac.com.

Return Air Filter Grille:
Bard offers the RFG return air filter
grille, which may be used in applications
where outdoor air is not brought into the
structure through vent options. If vent
options are used, the filter tray inside the
Bard Wall Mount unit must be used.
