Air Filter (Not Factory-Installed) - BGH BMPE36CTL Manual

• The drain line should be insulated where necessary to prevent sweating and damage due to
condensate forming on the outside surface of the line.
• Make provisions for disconnecting and cleaning of the primary drain line should it become
necessary. Install a 3 inch trap in the primary drain line as close to the unit as possible. Make
sure that the top of the trap is below connection to the drain pan to allow complete drainage
of pan (See Fig. 5).
• Auxiliary drain line should be run to a place where it will be noticeable if it becomes operational.
Homeowner should be warned that a problem exists if water should begin running from the
auxiliary drain line.
• Plug the unused drain connection with the plugs provided in the parts bag, using a thin layer
of teflon paste, silicone or teflon tape to form a water tight seal.
• Test condensate drain pan and drain line after installation is complete. Pour water into drain
pan, enough to fill drain trap and line. Check to make sure drain pan is draining completely, no
leaks are found in drain line fittings, and water is draining from the termination of the primary
drain line.

8. Air filter (not factory-installed)

• External filter or other means of filtration is required. Units should be sized for a maximum of
300 feet/min. air velocity or what is recommended for the type filter installed.
Filter application and placement are critical to airflow, which may affect the heating
and cooling system performance. Reduced airflow can shorten the life of the system's
major components, such as motor, limits, elements, heat relays, evaporator coil or
compressor. Consequently, we recommend that the return air duct system have only
one filter location. For systems with a return air filter grill or multiple filter grills, can
have a filter installed at each of the return air openings.
If adding high efficiency filters or electronic air filtration systems, it is very important
that the air flow is not reduced. If air flow is reduced the overall performance and
efficiency of the unit will be reduced. It is strongly recommended that a profesional
installation technician is contacted to ensure installation of these such filtration
systems are installed correctly.
