Indoor Coil; Outdoor Coil; Unit Support - Payne PA10 User's Information Manual

If your system includes an indoor fan coil unit, the filter may be located in the unit where it connects with the return-air duct or
plenum. (See Fig. 5.) Remove the filter cover plate by sliding latches toward center of plate. Lift filter to clear lower flange. Filter is
spring-loaded and will "pop out". Reinstall filter, being certain to secure filter behind lower flange. When reinstalling cover plate,
secure plate behind upper flange then slide tabs outward.
Fig. 5—Removing Filter from Fan Coil Unit
The indoor fan coil unit may be located in the attic. In this instance the filter could be located behind the return air grille. Access the
filter by removing 2 screws from return air grille.

INDOOR COIL

If the split-system coil has only been operated with a clean filter in place, it should require minimal cleaning. You may use a vacuum
cleaner and soft brush attachment to remove any accumulation of dust from the top and underside of the finned coil surface. However,
only perform this maintenance when the coil is completely dry.
If you cannot get the coil clean by this method, call your dealer for service. It may be necessary to clean the coil with a detergent
solution and rinse it with water. This could require the removal of the coil. You should not attempt this yourself.

OUTDOOR COIL

If grass clippings, leaves, shrubbery, and debris are kept away from the outdoor unit, minimal care should be sufficient to keep the
system functioning properly. For proper drainage, debris must be removed periodically from the base pan. However, if the outdoor
coil becomes dirty, use a brush or vacuum cleaner and soft brush attachment to clean the exterior surface. If dirt is deep in the coil,
contact your dealer for service. The outdoor fan motor may have to be disconnected and the top panel removed to gain access to the
coil for thorough cleaning. Do not attempt this yourself.
OUTDOOR COIL—SEA COAST
If your unit is located near the ocean, special maintenance is required. Ocean mist/breeze carries salt, which is corrosive to most metals.
Although your new unit is made out of galvanized metal and is protected by top-grade paint, you should take the precaution of additional
maintenance which consists of periodically washing the unit. By washing all exposed surfaces and coil approximately every 3 months,
you will be adding additional life to your unit. Please consult your installing contractor for proper intervals/procedures for your geographic
area or service contact.

UNIT SUPPORT

Your split-system outdoor unit should be maintained at a level position. If its support should shift or settle so that the unit is no longer
level, you should correct the condition. Relevel it promptly to assure condensate drainage out of the unit. If you notice that water or ice
collects beneath the unit, arrange for it to be drained away from the unit.
