Routine Maintenance - RV Products Airxcel 45000 Installation, Operation And Maintenance Instructions

II. Operation During Cooler Nights
(Cooling Operation)
It is important when the outdoor temperature drops
in the evening or during the night to below 24°C
(75°F), that the thermostat (temperature control) be
set at a midpoint between "Warmer" and "Cooler". If
the setting is at "Cooler", the evaporator coil may
become iced-up and stop cooling. During the day
when the temperatures have risen above 24°C
(75°F), reset the thermostat switch to the desired
setting.
NOTE: Should icing-up occur, it is necessary to let
the cooling (evaporator) coil defrost before normal
cooling operation is resumed. During this time,
operate the unit in the "HIGH FAN" position with the
system at maximum air flow. When increased or full
air flow is observed, the cooling coil should be clear
of ice.
III. Short Cycling
When an air conditioner is in operation, its
compressor circulates
pressure. Once off, it will take two to three minutes
for this high pressure to equalize. The air conditioner
compressor is unable to start against high pressure.
Therefore, once the air conditioner is turned off, it is
important to leave it off for two to three minutes
before restarting. Short cycling the compressor (or
starting it before pressures have equalized), will in
some instances, kick the circuit breaker or overload.
IV. For Heating Operation Refer to Figure1, page
8).
NOTE: The heating assembly is intended to take the
chill out of the indoor air when the air is a few
degrees too cool for comfort. The heating assembly
is an effective "chill chaser". It is not a substitute for
a furnace.
Do not expect the heating coil on your heater to
glow. Because the fan draws in cold air and forces it
over the coil, the coil will not turn red. A hint of red
may occur where the moving air does not directly
touch the coil.
A. Turn the selector switch to the "LOW HEAT"
position. At "LOW HEAT", the fan operates on
LOW speed with air temperature rise at
maximum.
B. Rotate the thermostat (temperature control)
switch to the position that is the most
comfortable to you. The thermostat will turn the
heater on when the temperature of the air
entering the air conditioning units drops below
this setting a few degrees, and automatically
turns off when the temperature of the air
entering the air conditioner rises a few degrees
above this setting. The heater will continue to
cycle on and off in this fashion until the selector
switch is turned to another mode of operation.
C. Position the louvers to the desired direction the
discharge air is to flow.
Discharge air temperature can be controlled to
some extent by opening and or closing the
louvers. When the louvers are closed, he
warmest localized discharge air is achieved.
Fully opened louvers will throw the warm
discharge air to the back and front of the vehicle
and straight down for more efficient circulation
refrigerant under high
and faster
temperature is lower with the louvers fully
opened, the heating capacity is still the same.
NOTE: If dirty filters or overly restricted louver
position results in a cessation of electric heat, turn
off power to the unit at the mode selector switch.
Wait ten (10) minutes and restore power. The heater
is equipped with a safety lock out switch. Correct the
low air event to ensure proper operation.
V. For Air Circulation Only (Refer to Figure 1,
page 8).
A. Turn the selector switch to "LOW FAN" or, for
maximum air flow, to "HIGH FAN".
B. Position the louvers to the desired direction
the discharge air is to flow.
NOTE: When the selector switch is in the "LOW
FAN" or "HIGH FAN" position, the blower motor will
operate continuously.
VI. ROUTINE MAINTENANCE
I. Owner – One of the biggest advantages to
your new Coleman®-Mach® Air Conditioner is
that the needed maintenance needed to keep
the unit in good working order is minimal. In
fact, about the only thing you, the owner, must
take care of is the cleaning and replacement
of the filters.
Filters are made from long life non-allergenic natural
fibers which can be cleaned and reused, and which
completely filter the circulated air when the air
conditioner is in operation. If the filters are not
cleaned at regular intervals, they may become
partially clogged with lint, dirt, grease, etc. A clogged
filter will produce a loss of air volume and may
eventually cause an icing-up of the cooling
(evaporator) coil.
The ceiling assembly and the outside shroud can be
cleaned with a damp cloth. When required, a mild
detergent can be used.
IMPORTANT
Do not operate your air conditioner for extended
periods of time without the filter installed.
An even more serious condition occurs when the
air conditioner is operated without a filter. When
this happens, the lint, grease, etc. that are
normally stopped
accumulating in the cooling coil. This not only
leads to a loss of air volume and a possible icing-
up of the cooling coil, but could also result in
serious damage to the operating components of
the air conditioner. We recommend that the filters
be cleaned and changed at least every two weeks
when the air conditioner is in operation.
