Cabinet
Front
The cabinet
front
and
discharge air grille
can
be
cleaned
with
a
water
dampened cloth. Under no circumstances should hydro-
carbon-based cleaners (e.g. acetone, benzene, naphtha gaso-
line,

YEARLY
MAINTENANCE
AND
CLEANING
NOTE:
Use
a mild biodegradable detergent
such
as
Simple
Green"" when cleaning the unit. Spedal 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.
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
coils,
and
condenser coils,
basepan,
and
drain
passages.
Sched-
uled 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 con-
struction site
or
sea
coast, must be cleaned more often. A
minimum
of
four (4) times a year
will
maintain proper opera-
tional 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
U!
bubble
tilt
to the outside
and
level from right
to
left.
Contact your
sales
person for
detailed maintenance
or
cleaning instructions.

and
the water temperature
no
higher
than 120'F.

the non-compressor side
of
the
unit
up
no
higher than

Remove
excess
water
left
in
the
basepan
by
wiping the
basepan
with a dry cloth.
