UNIT OPERATION AND SAFETY HAZARD
Failure to follow this warning could cause personal
injury, death and/or equipment damage.
Puron (R--410a) refrigerant systems operate at higher
pressures than standard R--22 systems. Do not use R--22
service equipment or components on Puron refrigerant
equipment.

WARNING
FIRE, EXPLOSION HAZARD
Failure to follow this warning could result in personal
injury, death and/or property damage.
1. Improper installation, adjustment, alteration, service,
or maintenance can cause property damage, personal
injury, or loss of life. Refer to the User’s Information
Manual provided with this unit for more details.
2. Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any other
appliance.
What to do if you smell gas:
1. DO NOT try to light anny appliance.
2. DO NOT touch any electrical switch, or use any
phone in your building.
3. IMMEDIATELY call your gas supplier from a
neighbor’s phone. Follow the gas supplier’s
instructions.
4. If you cannot reach your gas supplier, call the fire
department.

WARNING
FIRE, EXPLOSION HAZARD
Failure to follow this warning could result in personal
injury or death.
Disconnect gas piping from unit when pressure testing at
pressure greater than 0.5 psig. Pressures greater than
0.5 psig will cause gas valve damage resulting in hazardous
condition. If gas valve is subjected to pressure greater than
0.5 psig, it
must
be replaced before use. When pressure
testing field-supplied gas piping at pressures of 0.5 psig or
less, a unit connected to such piping must be isolated by
closing the manual gas valve(s).

WARNING
Cleaning
Inspect unit interior at beginning of each heating and cooling
season and as operating conditions require. Remove unit top
panel and/or side panels for access to unit interior.
Coil Maintenance and Cleaning Recommendation
Routine cleaning of coil surfaces is essential to maintain proper
operation of the unit. Elimination of contamination and removal
of harmful residues will greatly increase the life of the coil and
extend the life of the unit. The following maintenance and
cleaning procedures are recommended as part of the routine
maintenance activities to extend the life of the coil.
Remove Surface Loaded Fibers
Surface loaded fibers or dirt should be removed with a vacuum
cleaner. If a vacuum cleaner is not available, a soft non-metallic
bristle brush may be used. In either case, the tool should be
applied in the direction of the fins. Coil surfaces can be easily
damaged (fin edges can be easily bent over and damage to the
coating of a protected coil) if the tool is applied across the fins.
NOTE
: Use of a water stream, such as a garden hose, against a
surface loaded coil will drive the fibers and dirt into the coil. This
will make cleaning efforts more difficult. Surface loaded fibers
must be completely removed prior to using low velocity clean
water rinse.
Periodic Clean Water Rinse
A periodic clean water rinse is very beneficial for coils that are
applied in coastal or industrial environments. However, it is very
important that the water rinse is made with very low velocity
water stream to avoid damaging the fin edges. Monthly cleaning
as described below is recommended.
Routine Cleaning of Coil Surfaces
Monthly cleaning with Totaline
®
environmentally sound coil
cleaner is essential to extend the life of coils. This cleaner is
available from Carrier Replacement parts division as part number
P902-0301 for a one gallon container, and part number
P902-0305 for a 5 gallon container. It is recommended that all
coils, including standard aluminum, pre-coated, copper/copper or
E-coated coils be cleaned with the Totaline environmentally
sound coil cleaner as described below. Coil cleaning should be
part of the unit’s regularly scheduled maintenance procedures to
ensure long life of the coil. Failure to clean the coils may result in
reduced durability in the environment.
Avoid the use of:
S
coil brighteners
S
acid cleaning prior to painting
S
high pressure washers
S
poor quality water for cleaning
Totaline environmentally sound coil cleaner is non-flammable,
hypoallergenic,
nonbacterial,
and
a
USDA
accepted
biodegradable agent that will not harm the coil or surrounding
components such as electrical wiring, painted metal surfaces, or
insulation. Use of non-recommended coil cleaners is strongly
discouraged since coil and unit durability could be affected.

UNIT DAMAGE HAZARD
Failure to follow this caution may result in corrosion and
damage to the unit.
Harsh chemicals, household bleach or acid or basic cleaners
should not be used to clean outdoor or indoor coils of any
kind. These cleaners can be very difficult to rinse out of the
coil and can accelerate corrosion at the fin/tube interface
where dissimilar materials are in contact. If there is dirt
below the surface of the coil, use the Totaline
environmentally sound coil cleaner as described above.
