OPERATIONAL INSTRUCTIONS
Description and Illustration of the Machine
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 dehumidified 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 configurable by the user.
e system is composed of: (A) Compressor, (B) Condenser, (D) Evaporator, (F) 4-Way Valve and Pressurized Refrigerant R410a.

Cooling 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) flows through the evaporator which has been made signficantly cold.
e air then comes out cooled and removed of humidity (the “supply air”).

Heating Mode – Description of Operation
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 repeated continuously over a long period of time leads to a reduction in the air temperature and humidity levels inside the vehicle.

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.

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 flow is not obstructed by anything and create an air duct between the opening and the machine, if necessary.
e cutout should be roughly 50 in2 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.
Air Ducting
Ductwork Best Practices:
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 efficiency, it is advised to:
· Route the air ducts as short and flat 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).

INSTALLATION INSTRUCTIONS
Electrical Hookup
Connection and Powering Up of System:
Connect the receiver extension socket to the system, and power up the machine by inserting the included power plug into a 115V/60Hz outlet.
A 12 VDC connection is also connected from the vehicle’s battery to supply power to the unit’s PCB. Use the yellow wire next to the AC power cord to connect to the vehicle battery to facillitate power to the heat pump system’s command control module.
Before switching on, ensure that the electrical supply and the extension used are capable of withstanding the power input required by the system (see technical data and/or nameplate).
e installation process is now complete. For any troubleshooting steps, please see Page 22.
