SERVICE
Before performing service or maintenance operations on
unit, turn off main power switch to unit. Electlical shock
could cause personal injury.
Puron® (R-410A) refrigerant systems operate at higher
pressures than stan&ud R-22 systems. Do not use R-22
service equipment or components on Puron refrigerant
equipment. If service equipment is not rated for Puron
refrigerant, equipment damage or personal inju U may
_esult.
1. Improper installation, adjustment, alteration, service,
or maintenance can cause property damage, personal
inju U, 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 any appliance.
2. DO NOT touch any electrical switch, or use any
phone in your building.
3. IMMEDIATELY call your gas supplier t]om a neigh-
bor's phone. Follow the gas supplier's instructions.
4. If you cannot reach your gas suppliel: call the file
department.
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 stremn to avoid
&Lmaging 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 tx)02-0301 for a
one gallon containel: and part number P902-0305 for a 5 gallon
container It is recommended that all coils, including standard
_duminum, 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
reguldy scheduled maintenance procedures to ensure long life
of the coil. Failure to clean the coils may result in leduced du-
rability in the environment.
Avoid the use of:
• coil brighteners
• acid cleaning prior to painting
• high pressure washers
• poor quality water for cleaning
Totaline environmentally sound coil cleaner is non-flamma-
ble, hypoallergenic, nonbacterial, and a USDA accepted biode-
gradable agent that will not harm the coil or surrounding com-
ponents such as electrical wiring, ptdnted metal surfaces, or in-
sulation. Use of non-recommended coil cleaners is strongly
discouraged since coil and unit durability could be affected.

Equipment
• 21/2 gallon garden sprayer
• water rinse with low velocity spray nozzle
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 lesulting in hguzardous
condition. If gas wdve is subjected to plessure greater than
0.5 psig, it must be replaced before use. When pressure
testing field-supplied gas piping at pressmes of 0.5 psig or
less, a unit connected to such piping must be isolated by
closing the manual gas valve(s).
Cleaning -- Inspect unit interior at beginning of each heat-
ing and cooling season and as operating conditions require. Re-
move unit top panel and/or side panels for access to unit interiol:
COIL MAINTENANCE AND CLEANING RECOMMEN-
DATION- Routine cleaning of coil surfaces is essential
to maintain proper operation of the unit. Elimination of
contamination and lemoval of hmmful residues will greatly in-
crease the life of the coil and extend the life of the unit. The fol-
lowing mtdntenance and cleaning procedmes are recommend-
ed 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 cleanel: If a vacuum
cleaner is not avtdlable, a soft non-metallic bristle brush may
be used. In either case, the tool should be applied in the direc-
tion of the fins. Coil surfaces can be easily &imaged (fin edges
can be easily bent over and damage to the coating of a protect-
ed 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
Harsh chemicals, household bleach or acid or basic clean-
ers 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 inter-
face where dissimilar materials are in contact. If there is
dirt below tile surface of the coil, use tile Totaline environ-
mentally sound coil cleaner as described above.
High velocity water from a pressure washel: garden hose,
or compressed air should never be used to clean a coil. The
force of the water or air jet will bend the fin edges and
increase airside pressure drop. Reduced unit performance
or nuisance unit shutdown may occm:
Totaline Environmentally Sound Coil Cleaner Al)l)fication
h_strnctions
1. Proper eye protection such as safety glasses is recom-
mended during mixing and application.
2. Remove all surface loaded fibers and dirt with a vacuum
cleaner as described above.
3. Thoroughly wet finned surfaces with clean water and a
low velocity garden hose, being careful not to bend fins.
4. Mix Totaline environment_dly sound coil cleaner in a
21/2 gallon gmden sprayer according to the instructions
included with the cleaner The optimum solution temper-
ature is 100 E
NOTE: Do NOT USE water in excess of 130 E as the enzy-
matic activity will be destroyed.
