Description and Illustration of the Machine
OPERATIONAL INSTRUCTIONS
e purpose of this machine is to provide greater control of the air temperature
within the vehicle that it is installed (such as motor homes, caravans, recreational
vehicles, etc.). When the ambient outdoor temperature is hot and humid, it can
supply the vehicle with cool and dehumidied air via the refrigeration cycle.
It can also run this process in reverse, to supply heated air into the vehicle, whether
as a supplement, or replacement for the vehicle’s original heating system. In both
instances, the setting of the desired air temperature is congurable by the user.
Cooling Mode - Description of Operation Heating Mode - Description of Operation
By changing physical state from liquid to gas, the
refrigerant heats or cools the components through
which it passes. e air that is drawn into the system
(the “return air”) by the fan blower (C) ows through
the evaporator which has been made signcantly cold.
e air then comes out cooled and removed of
humidity (the “supply air”).
is process repeated continuously over a long period
of time leads to a reduction in the air temperature
and humidity levels inside the vehicle.
e method of heating is quite similar to that of
cooling, however the process occurs in reverse.
e refrigeration cycle is reversed by the 4-way valve
switching over (F). e internal coil becomes the
condenser rather than the evaporator, thereby heating
the air that passes through it.
is process takes more standby time as the internal
coil spends a few minutes heating up to begin working,
in addition to periodic defrost cycles from the machine.
e system is composed of: (A) Compressor, (B) Condenser, (D) Evaporator, (F) 4-Way Valve
and Pressurized Refrigerant R410a.

Best Practices for Optimal Performance
OPERATIONAL INSTRUCTIONS
For best results, the following tips are given in order to improve the output and
eciency of the machine:
Increase the vehicle’s insulation amount by sealing o openings and covering
glass surfaces with reective or blackout curtains.
When running the machine, select the desired temperature and fan speed and
ensure that the air vents are oriented in a suitable and proper direction.
Avoid the frequent opening of doors and/or windows when not necessary.
To prevent mechanical malfunctions and minimize risk of personal injury, ensure
that the following precautions are abided by:
Avoid obstruction of the ventiled air inlet. Do not cover with cloth, paper, etc.
Do not put hands or insert ngers into any of the machine’s openings.
Do not spray water into or onto the surface of the machine.
Keep ammable substances and objects 3 feet or more away from the machine.
Clean the machine’s air lters periodically.

Description of the Controls
OPERATIONAL INSTRUCTIONS
Selecting the Functional Mode:
Press the MODE button to cycle between the available states on the machine.
After two seconds have elapsed, the system will conrm the selection with an
audible beep from the machine’s speaker. Always point the remote controller
toward the wall pad when sending commands to ensure the best reception.
NOTE: When rst switching on the system, the machine will stay in standby
mode for a few minutes before the compressor begins operating.
