CLEANING

NOTE:

Use a mild biodegradable detergent when

cleaning the unit. Special care must be taken to protect the
unit's control board and other electrical components from
getting any water on them while cleaning. The use of harsh
or caustic cleaning agents or materials such as bleach or
coil cleaners that are not designed for PTAC products will
cause damage or deterioration of the aluminum fin or coil
material and is not recommended. Care must be taken not
to bend the aluminum fin stock.

Base pan and Condenser coil

Before cleaning the base pan and condenser coil, turn
OFF unit mode switch and disconnect power to the unit.

To disconnect power, either unplug the power cord at the
wall outlet or subbase, or disconnect power at the fuse box
or circuit breaker

1. Create a water tight seal by tightly covering the entire
control panel area and fan motor with plastic. Creating this
seal prevents water from entering the control area or the
fan motor and damaging the unit.

2. Spray condenser coil and base pan down with water.
Next spray a mild biodegradable detergent onto the
condenser coil and base pan. Let set for five (5) minutes.

3. Rinse condenser coil and base pan with water again

NOTE:

Ensure water pressure is no higher than that of an

ordinary garden hose and the water temperature no higher

than 120

Routine scheduled Maintenance

To achieve continuing top performance and high efficiency,
establish a “once a year" cleaning/inspection schedule
for the  unit.  Take  the  unit  out  of  the  sleeve  and
thoroughly clean and rinse.  Be sure to include in the
yearly cleaning the  evaporator  coil,  and  condenser  coil,
basepan,  and drain passages.

Scheduled maintenance can be accomplished by either
qualified local maintenance staff or by an authorized

servicer. They must follow the instructions described in this
manual.

Adverse Operating Conditions Maintenance

Units  operating  in  dusty  or  corrosive  locations;  i.e.
dusty construction site or sea coast, must  be cleaned
more  often.  A  minimum  of  four  (4)  times  a  year  will
maintain proper operational conditions and protect unit
components.

Wall sleeve

Clean the wall sleeve while cleaning the unit. The
caulking around the sleeve should be checked to make
sure that any potential air and water openings around the
sleeve are properly sealed. The wall sleeve's level
should also be rechecked. Proper leveling for most
installations are a 1

4 tilt to the outside and level from

right to left. Contact your sales person for detailed
maintenance or cleaning instructions.
