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 dehumidied 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 congurable 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 signcantly 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
eciency of the machine:
Increase the vehicle’s insulation amount by sealing o openings and covering
glass surfaces with reective 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.

Routine Maintenance
OPERATIONAL INSTRUCTIONS
Periodic Cleaning Methods:
Using a soft and moist cloth, wipe down the surface
area of the machine periodically in order to remove
dust. Use clean water or a non-aggresive detergent if
necessary. Do not use petrol or solvents to clean the
machine. Repeat this process every season.
Remove the air lters and wash gently by hand with a
detergent solution, allowing it to dry before inserting
back into place. Repeat this process every 30-45 days.
If an optional active carbon lter is installed, it is
advised to replace them yearly.
Checking Best Practices:
Periodically inspect the system, particularly the points
of drainage, as well as the air intake points.
Ensure that the system is able to drain succesfully. If
there are any sort of clogs, clear the blockage before
continuing to operate the system.
Conrm that there are no obstructions in the oor
openings. For best performance, it is important that
the condenser-side return air can enter and exit the
system without any restrictions.

Getting Started
INSTALLATION INSTRUCTIONS
Unpacking and Handling the System:
Installation should only be performed by those with sucient technical knowledge. In addition, the proper tools and equipment should
be used for the installation process, to ensure the safety of themselves and those nearby.
Observe and follow any special instructions or warnings present
on the outer packaging before attempting to handle the system.
Using equal force on both sides,
lift the machine out of the box.
Lift the machine by using only the
handles or the belts on the base.
When resting the system on a surface, assure to distribute the
weight of the machine by supporting it on both sides equally.
Seek the help of an additional person to assist in transferring the system
to the nal place of installation, being sure to do so slowly and carefully.
14
Selecting the Location of Installation
INSTALLATION INSTRUCTIONS
In order for the machine to properly provide uniform climate control in the vehicle,
it should be installed as close to the center as possible, inside a housing/compartment.
Position the machine so as to ensure ease of access, and facillitation of both
installation and disassembly.
Place the template used for assembly within the compartment intended for
installation and verify the available space for the needed openings in the oor.
Avoid the frequent opening of doors and/or windows when not necessary.
In order to minimize transmission of noise and/or vibration during operation, the
machine must have a minimum clearance of 1 inch away from walls and ttings
on either side.
e machine must be installed on the oor, and as horizontally level as possible.
To allow for ease of lter replacement, keep a distance of 8 inches from the
front of the machine and the interior wall of the compartment.
If incorporating any external compartments (such as false bottoms), the air that
is to be treated must be drawn in from the vehicle’s passenger compartment.
Drawing in air from outside can negatively impact the performance of the
system signicantly.

Preparation of Floor Openings and Unit Fastening
INSTALLATION INSTRUCTIONS
Clearances and Procedure for Securing the System:
Installation of the machine involves creating openings in the oor. ese openings
must not be covered or obstructed by parts of the chassis frame or similar xtures.
It is also important to block the openings from splashes coming from the wheels,
using a splash guard or something similar if necessary.
Take special care to ensure a gap of at least 1 inch is left between the machine and
its adjacent walls. Use the provided kit to secure the machine to the interior oor.
e machine must be installed completely level. ere is a maximum angle of
10° to prevent condensation leakage.
Prior to cutting the holes, verify that there are no cables, gas pipes, or parts of
the chassis frame or similar xtures underneath or hidden below.
Seal the machined surfaces of the oor openings with water-repellant solutions.

Recirculation Air Compartment Opening
INSTALLATION INSTRUCTIONS
Final Cutout Opening for Recirculation Air:
Ductwork Best Practices:
Air Ducting
Create an additional hole in the compartment
where the system is installed, in order to permit
recirculation of the internal air.
It would be best to locate the cutout near to the
front of the machine. If the opening cannot be
made near the machine, ensure that the air ow is
not obstructed by anything and create an air duct
between the opening and the machine, if necessary.
e cutout should be roughly 50 in
2
in size, and
the hole will be closed with a grille supplied.
Only allow this recirculation air to enter the
compartment from within the passenger section.
If the air entering this opening is from the outside,
the performance of the machine would diminish.
Finally, install the condensation drain tubes
provided with the system onto the bottom ports.
Craft the ducting used to distribute the air using trade
parts which are not included with this system supply.
It is advised to use cardboard pipe for air conditioning,
with an aluminum core and external PVC covering.
e nominal Inner Diameter should be sized up to 2”-3/8,
and the Outer Diameter up to 2”-1/2.
e tapered hole on the air outlet allows the ventilation
ducts to be joined by pressing them together.
Use either the outlet on the coil side, or the side outlet (by
removing the guard and closing the front holes) to connect
the ducts.
For optimal eciency, it is advised to:
• Route the air ducts as short and at as possible.
• Do not exceed 16 ft in duct length.
• Avoid laying the air ducts near any sources of heat.
Avoid condensation on the ducting by insulating the
pipes with insulation material (sold separately).
