Your Magic-Pak is designed to give many years of efficient,
satisfactory service. However, the varied air pollutants
commonly found in most areas can affect longevity and
safety. Chemicals contained in everyday household items
such as laundry detergents, cleaning sprays, hair sprays,
deodorizers, and other products which produce airborne
residualsmay havean adverseaffectupon themetalsused
to construct your appliance.
Itis importantthatyou periodicallyinspectyour unit.Visually
inspect all flue product carrying areas of the furnace, the
vent-air intake system, main gas burners, and heat
exchanger. You will be able to make this observation by
removing the access panel located on the center portion of
thecabinet.Ascrewdriverisneededtoremove thispanel.A
flashlight will be useful. Make one inspection prior to the
beginning of the heating season and another half way

make sure it does not touch the fins of the coil. Your
filter should be checked every 4 to 6 weeks.
2. Indoor Coil This coil must be clean at all times,
especiallyfor efficientcoolingperformance. Shouldany
lintor dirtcollecton thecoilfins, youcanusually remove
this accumulation using an ordinary vacuum cleaner
hosewith acrevicetool orbrushattachment.Be careful,
the coil fins are very fragile and are easily damaged.
3. Condensate Drain During cooling, the moisture
removed from indoors collects on the indoor coil, drops
tothe drainpanat thebottom ofthe coiland thendrains
away through a plastic hose connected to the stub at
the front of the drain pan. The condensate then drains
tothe unitbase pan.Make sure this drain connection
is kept open to keep condensate from overflowing
the pan.
