containing two filters are taped together at the factory to facili-
tate removal. This should be done by end user as new filters are
installed.
Condensate Drain Pans
The condensate drain should be checked quarterly by cleaning and
flushing to ensure proper drainage.
Refrigerant System
Verify air and water flow rates are at proper levels before
servicing. To maintain sealed circuitry integrity, do not install
service gauges unless unit operation appears abnormal. Check to
see that unit is within the superheat and subcooling temperature
ranges shown in Tables 22-33. If the unit is not within these
ranges, recover and reweigh in refrigerant charge.
REFRIGERATING EQUIPMENT.
Where electrical components are being changed, they shall be fit
for the purpose and to the correct specification. At all times the
manufacturer’s maintenance and service guidelines shall be fol-
lowed.
The following checks shall be applied to installations using flam-
mable refrigerants:
• the actual refrigerant charge is in accordance with the
room size within which the refrigerant containing parts are
installed;
• the ventilation machinery and outlets are operating ade-
quately and are not obstructed;
• if an indirect refrigerating circuit is being used, the second-
ary circuit shall be checked for the presence of refrigerant;
• signs on the equipment continues to be visible and legible.
Markings and signs that are illegible shall be corrected;
• refrigerating pipe or components are installed in a position
where they are unlikely to be exposed to any substance
which may corrode refrigerant containing components,
unless the components are constructed of materials which
are inherently resistant to being corroded or are suitably
protected against being so corroded.
DETECTION OF FLAMMABLE REFRIGERANTS
Under no circumstances shall potential sources of ignition be used
in the searching for or detection of refrigerant leaks. A halide torch
(or any other detector using a naked flame) shall not be used.
The following leak detection methods are deemed acceptable for
all refrigerant systems:
Electronic leak detectors may be used to detect refrigerant leaks
but, in the case of flammable refrigerants, the sensitivity may not
be adequate, or may need re-calibration. (Detection equipment
shall be calibrated in a refrigerant-free area.). Ensure that the de-
tector is not a potential source of ignition and is suitable for the re-
frigerant used. Leak detection equipment shall be set at a percent-
age of the LFL gas (25% maximum) and it is confirmed.
Leak detection fluids are also suitable for use with most refriger-
ants but the use of detergents containing chlorine shall be avoided
as the chlorine may react with the refrigerant and corrode the cop-
per pipe-work.
NOTE: Examples of leak detection fluids are the bubble method
and fluorescent dye method. If a leak is suspected, all naked
flames shall be removed/extinguished. If a leakage of refrigerant is
found which requires brazing, all of the refrigerant shall be recov-
ered from the system, or isolated (by means of shut off valves) in a
part of the system remote from the leak.
Compressor
Conduct annual amperage checks to ensure that amp draw is no
more than 10% greater than indicated on the serial plate data.
Fan Motors
All units have lubricated fan motors. Fan motors should never be
lubricated unless obvious, dry operation is suspected. Periodic
maintenance oiling is NOT recommended as it will result in dirt
accumulating in the excess oil and cause eventual motor failure.
Conduct annual dry operation check and amperage check to
ensure amp draw is no more than 10% greater than indicated on
serial plate data and remove any build up on the blower
assembly.
Condensate Drain Cleaning
Clean the drain line and unit drain pan at the start of each cooling
season. Check flow by pouring water into drain. Be sure trap is
filled to maintain an air seal.
Air Coil Cleaning
Remove dirt and debris from evaporator coil as required by
condition of the coil. A 10% solution of dishwasher detergent and
water is recommended for cleaning both sides of the coil, followed
by a thorough water rinse. Clean coil with a stiff brush, vacuum
cleaner, or compressed air. Use a fin comb of the correct tooth
spacing when straightening mashed or bent coil fins.
Condenser Cleaning
Water-cooled condensers may require cleaning of scale (water
deposits) due to improperly maintained closed-loop water
systems. Sludge build-up may need to be cleaned in an open water
tower system due to induced contaminants.
Local water conditions may cause excessive fouling or pitting of
tubes. Condenser tubes should therefore be cleaned at least once a
year, or more often if the water is contaminated.
Proper water treatment can minimize tube fouling and pitting. If
such conditions are anticipated, water treatment analysis is
recommended. Refer to the Carrier System Design Manual, Part 5,
for general water conditioning information.
Clean condensers with an inhibited hydrochloric acid solution.
The acid can stain hands and clothing, damage concrete, and,
without inhibitor, damage steel. Cover surroundings to guard
against splashing. Vapors from vent pipe are not harmful, but take
care to prevent liquid from being carried over by the gases.
Warm solution acts faster, but cold solution is just as effective if
applied for a longer period.
GRAVITY FLOW METHOD
Do not add solution faster than vent can exhaust the generated
gases.
IMPORTANT: Units should never be operated without a filter.
CAUTION
Equipment should never be used during construction or
renovation due to possibility of contaminants entering the air
coil of the equipment which permanently affects the
performance and may shorten the life of the equipment.
IMPORTANT: When a compressor is removed from this unit,
system refrigerant circuit oil will remain in the compressor. To
avoid leakage of compressor oil, the refrigerant lines of the
compressor must be sealed after it is removed.
CAUTION
Follow all safety codes. Wear safety glasses and rubber gloves
when using inhibited hydrochloric acid solution. Observe and
follow acid manufacturer’s instructions.
