Maintenance - Magic-pac MHP4 Series Installation And Maintenance Instructions Manual

MAINTENANCE

Disconnect all electrical power to the unit before
conducting any maintenance procedures. Failure to
disconnect the power could result in personal injury or
death.
Periodic inspection and maintenance normally consists of
changing or cleaning filters and (under some conditions)
cleaning the coils.
Filter
Inspect the filter once a month. Replace disposable filter or
clean the washable filter as necessary (a minimum of three
times each heating or cooling season is recommended). Do
not replace washable filter with a disposable filter unless an
installation was made in which the filter was mounted exterior
to the unit.
Motors
The indoor and outdoor fan motors are permanently
lubricated and require no maintenance.
Outdoor Coil
Foreign material should not be allowed to accumulate on
the outdoor coil surface or other parts in the air circuit.
Cleaning should be as often as necessary to keep the coil
clean. To clean the coil, remove the lower access panel and
blow out debris by using compressed air or water. Be sure
power to unit is shut off before using water to clean the
coil.
Care should be used when cleaning the coils so that
the coil fins are not damaged.
Outdoor Base Drain
Foreign material should not be allowed to clog the drain hole.
Inspect and clear drain opening prior to heating season.
