IX. OPERATION AND MAINTENANCE
These instructions are a general guide for operating
and maintaining the Mach 10, 230/240 VAC, 50 Hz,
Coleman®-Mach® roof top Air Conditioners.
This appliance is not intended for use by persons
(including children) with reduced physical, sensory
or mental capabilities, or lack of experience and
knowledge,
unless
supervision or instruction concerning use of the
appliance by a person responsible for their safety.
Children should be supervised to ensure that they
do not play with the appliance and cleaning and user
maintenance shall not be made by children without
supervision.
Your air conditioner has been designed for years of
safe, dependable operation. These instructions
contain a general description on the operation of the
unit, how to set up and operate the controller, and a
list of routine maintenance items.
i. MODEL & SERIAL NUMBER
The model number and serial number are on the
back page of this booklet and on the unit data
plate.
ii. OPERATING GUIDELINES
This air conditioner is designed to provide cooling
and dehumidification. NOTE: The electric
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. The performance
of both units can be optimized by following these
simple guidelines:
• Keep doors and windows closed to prevent the
loss of conditioned air.
• Keep the curtains closed to reduce heat gain.
• Set

temperature.
• A low fan speed will reduce sound level and
improve dehumidification when the unit is
cooling.
• Properly adjust the air flow with the slides on
the front and rear of the ceiling assembly.
• Never obstruct the air flow to the ceiling
assembly.
• Do not spray water or any cleaning fluid into
the ceiling assembly. The ceiling assembly
should be cleaned with a damp cloth.
• Do not put any object, including your hands,
into the openings of the ceiling assembly.

iii. ADJUSTING THE AIR FLOW
The conditioned air is distributed through the
ceiling assembly: Slides on the front and rear
can be moved to throttle the air flow to the front
and rear, and the round louvers can be adjusted
to direct air flow downward. The round louvers
can be opened and closed to adjust airflow and
given
also spin 360 degrees allowing air flow to be
directed where desired. It is suggested to use
the round supply louvers in heating mode to
keep air from stratifying in the coach.
iv. CONTROL PANEL
This RV air conditioner is operated from the
control panel in the ceiling assembly. There are
three controls on the ceiling assembly that help
you control the air conditioner:
A. The Selector Switch – The selector switch
determines which mode of operation the air
conditioner will be in. By rotating the selector
switch, the operator can obtain any system
function desired.
B. The Thermostat (temperature control) –
The thermostat regulates the "ON" and
"OFF" temperature setting at which the
compressor will operate. See Figure 1.
C. Louvers – The louvers are located at both
ends and the face of the ceiling assembly
and are used in directing the discharge air
from the unit.

comfortable to you. The thermostat will
turn the compressor on when the
temperature of the air entering the air
conditioner rises a few degrees above the
setting you have selected. When the
temperature of the air entering the air
conditioner drops below the selected
setting, the thermostat will turn the
compressor off. The air conditioner, while
in the cooling mode, will continue to cycle
