Homeowner Maintenance

IMPORTANT

Do not operate system without a filter. A filter is required

to protect the coil, blower, and internal parts from

excessive dirt and dust. The filter is placed in the return

duct by the installer.

•

Inspect air filters at least once a month and replace or

clean as required. Dirty filters are the most common

cause of inadequate heating or cooling performance.

•

Replace disposable filters. Cleanable filters can be

cleaned by soaking in mild detergent and rinsing with

cold water.

•

Install new/clean filters with the arrows on the side

pointing in the direction of air flow. Do not replace a

cleanable (high velocity) filter with a disposable (low

velocity) filter unless return air system is properly

sized for it.

•

If water should start coming from the secondary drain

line, a problem exists which should be investigated

and corrected. Contact a qualified service technician.

Professional Maintenance

NOTICE

Failure to follow instructions will cause damage to the

unit.

This unit is equipped with an aluminum coil. Aluminum

coils may be damaged by exposure to solutions with

a pH below 5 or above 9. The aluminum coil should

be cleaned using potable water at a moderate pressure

(less than 50psi). If the coil cannot be cleaned using

water alone, it is recommended to use a coil cleaner

with a pH in the range of 5 to 9. The coil must be rinsed

thoroughly after cleaning.

In coastal areas, the coil should be cleaned with potable

water several times per year to avoid corrosive buildup

(salt).

Repairing or Replacing Cabinet Insulation

IMPORTANT

DAMAGED INSULATION MUST BE REPAIRED OR

REPLACED before the unit is put back into operation.

Insulation loses its insulating value when wet, damaged,

separated or torn.

Page 16 of 19

Matte- or foil-faced insulation is installed in indoor equipment

to provide a barrier between outside air conditions

(surrounding ambient temperature and humidity) and the

varying conditions inside the unit. If the insulation barrier is

damaged (wet, ripped, torn or separated from the cabinet

walls), the surrounding ambient air will affect the inside

surface temperature of the cabinet. The temperature/

humidity difference between the inside and outside of the

cabinet can cause condensation on the inside or outside

of the cabinet which leads to sheet metal corrosion and

subsequently, component failure.

Repairing Damaged Insulation

Areas of condensation on the cabinet surface are an

indication that the insulation is in need of repair.

If the insulation in need of repair is otherwise in good

condition, the insulation should be cut in an X pattern,

peeled open, glued with an appropriate all-purpose glue

and placed back against the cabinet surface, being careful

to not overly compress the insulation so the insulation can

retain its original thickness. If such repair is not possible,

replace the insulation. If using foil-faced insulation, any

cut, tear, or separations in the insulation surface must be

taped with a similar foil-faced tape.

Electric Shock Hazard.

Can cause injury or death.

Foil-faced

characteristics similar to metal. Be sure

there are no electrical connections within

1/2ʺ of the insulation. If the foil-faced

insulation comes in contact with electrical

voltage, the foil could provide a path for

current to pass through to the outer metal

cabinet. While the current produced may

not be enough to trip existing electrical

safety devices (e.g., fuses or circuit

breakers), the current can be enough

to cause an electrical shock hazard that

could cause personal injury or death.

1. CUT INSULATION IN X PATTERN

2. APPLY GLUE

3. PRESS GLUED TABS AGAINST CABINET

IMPORTANT

insulation

has

conductive

GLUE - Make sure there is

full coverage of glue on the

metal or insulation so there

are no areas where air

pockets may form which

can lead to sweating.
