USE GUIDE

AIR CONDITIONER SIZING

The ability of an air conditioner to cool a vehicle or maintain a desired temperature is dependent on the heat gain of the vehicle.

• Physical size of vehicle
• Window area
• Quality and amount of insulation
• Exposure to sunlight
• Number of people inside the vehicle
• Outside temperature

As a general rule, discharge air will be 15 – 20°F or 8 – 12°C cooler than the air entering the unit. For example, if the air entering the air conditioner is 80° F or 27° C. (return air), the supply air (dis-charge air) into the vehicle will be 60 – 65° F or 15 – 19 °C. As long as this temperature difference is 15 – 20 °F, or 8-12 °C is being maintained, the unit is operating properly. Again, give careful consideration to the vehicle heat gain variables. During extreme outdoor tem-peratures, the heat gain of the vehicle may be reduced by:As a general rule, discharge air will be 15 – 20°F or 8 – 12°C cooler than the air entering the unit. For example, if the air entering the air conditioner is 80° F or 27° C. (return air), the supply air (dis-charge air) into the vehicle will be 60 – 65° F or 15 – 19 °C. As long as this temperature difference is 15 – 20 °F, or 8-12 °C is being maintained, the unit is operating properly. Again, give careful consideration to the vehicle heat gain variables. During extreme outdoor tem-peratures, the heat gain of the vehicle may be reduced by:

• Parking the vehicle in a shaded area
• Keeping windows and doors closed
• Avoiding the use of heat producing appliances
• Using window shades (blinds and/or curtains)

For a more permanent solution to high heat gain situations, additional vehicle insulation, window awnings and/or window glass tinting should be considered.

CHOOSING PLACEMENT

This unit is specifically designed for installation on the roof of an RV. When determining your cooling requirements, the following should be considered:

• Size of RV
• Window area (increases heat gain).
• Amount of insulation in walls and roof.
• Personal comfort level required.

Maintain structural integrity, otherwise damage to product and/or RV could occur. The roof must be designed to support 130 pounds when RV is in motion. Normally a 200 lb. static load design will meet this requirement.

DIMENSIONS

REFRIGERANT

FILLING REFRIGERANT

NOTE: All Nomadic Air Conditioners shipped via land from manufacturer are pro-filled with the cor-rect refridgerant. This section only pertains to shipments delivered by air (internationally), or if the unit has had a leak and been repaired. Filling refridgerant should always be done by a professional

1.  Connect the manifold pressure gauge set to compressor inlet and outlet hoses.
2.  Connect the vacuum pump to the pressure gauge.
   • Power on and vacuum unit.
   • Attention: The time is not less than 45 minutes. The pressure ≤-0.1MPa.
   • Turn off the vacuum pump..
   • The pressure maintaining time is 5 minutes.
   • During this period, you should observe the pressure gauge.
   • If pressure goes up = air leakage.
3. In case of leakage:
   • Fill the system with nitrogen to 2 MPa and keep pressure,
   • Brush the tubes and connections with soap water to locate the leakage.
4. Please correct it and then repeat step one.

RUN TRIAL PRIOR TO INSTALL

1. Remove the vacuum pump.
2. Connect the refrigerant cylinder and fill the refrigerant from high pressure end.
3.  Pressure shall be between 0.5~0.8 MPa (within the limits of pressure gauge).
4. Turn off the refrigerant cylinder.
5. Power on and start the system.
6. The voltage should meet the requirements.
7. Check the compressor, evaporator, and condenser.
   • Change of pressure gauge.
   • Open the refrigerant cylinder.
8. Fill the refrigerant from the compressor inlet (low pressure end).
   • Watch the sight glass and the pressure gauge.
   • Pressure gauge:
   • High pressure:1.6~2.4MPa
   • Low pressure:0.1~0.3MPa
   • Refrigerant charge:550-600g

Sight glass: It is on top of the reservoir. In process of filling, the bubbles will decrease. When bub-bles subside, you should stop filling.

INSTALL

CUTTING THE OPENING

• Begin by marking your 14×14 rooftop opening from inside the vehicle, this way you can make sure that there are no electrical or other encumbrances in the way.
• Make sure the planned opening is centered on all 4 sides. This gives the best results for an easy installation.

TIP: USE A SHARPIE TO MARK YOUR 14X14 SQUARE INSIDE THE VEHICLE

• Using a 1/8-inch drill bit, drill each corner of your markings from inside your rig through the roof upwards. This will make it easier to mark your 14×14 opening from underside of your roof to the outside of your roof.
• Connect the dots you just drilled into your roof to make a perfect 14×14. Cut on the line.

TIP: MAKE YOUR CONNECTING LINES ONTO PAINTERS TAPE TO HELP WITH VISIBILITY. MEASURE TWICE TO ENSURE A 14X14 SQUARE.

PLACING THE UNIT ON ROOF

• Once the opening has been cut, use a file to smooth out the rough edges. Rough edges are not recommended for a waterproof seal.
• Clean surface with an oil repellent, such as Isopropyl alcohol diluted to 10%-15%, or other degreasers.
• Remove the Nomadic Cooling 3M 14×14 waterproof gasket from the box.
• Apply the 3M sticky side DOWN onto your vehicles roof, around the cut opening.
• Add a waterproof sealant around the edges of the 14×14 gasket. Use as much as needed. You can never waterproof too much for rooftop electronics.
• Place unit on roof over 14×14 gasket. Center the unit over the roof measuring side to side until the unit is centered on all four sides.

CAUTION DO NOT PUNCTURE / TEAR GASKET WITH MOUNTING BOLTS.

• Take the 4 mounting bolts provide and screw them into the threaded inserts off the base plate of the unit. Screw the bolts hand tight.
• From inside the vehicle, use the 2 long metal support mounting brackets and align them around the 4 bolts to attach the unit to the roof.
• NOTE: Modify your orientation of the mounting brackets (horizontal/vertical) to fit your spe-cific application.
• Use the mounting hardware provided, tighten bolts x4.
• Do not over-tighten mounting nuts. Bolts will rotate if over torqued.

CAUTION OVER TIGHTENING WILL BREAK BOLT FROM BASE PAN.

INSTALL

PLACING THE UNIT ON ROOF

• When securing unit to the vehicle increased compression of the gasket will level the unit against the roof. Use gasket tension to control A/C units’ distance from roof surface.

AIR CONDITIONER SHOULD BE RESTING ON THE GASKET, NOT THE VEHICLE.

CAUTION

OVER COMPRESSION OF THE UNIT TO THE ROOF MAY CAUSE FAN TO RUB AGAINST THE FAN HOUSING. INSURE BLADES ROTATE FREELY PRIOR TO STARTING THE AC UNIT.

WIRING & CONNECTING UNIT

• Make sure to use appropriately sized wiring (2 AWG) and fuse/breaker before connecting power to unit.
• We recommend a Blue Sea 187 Breaker between your power source and the A/C Unit.
• Nomadic Cooling 2000 – Blue Sea 187 100A
• Nomadic Cooling 3000 – Blue Sea 187 125A
• Use included copper butt connectors and attach to
  • DC power cables. Crimp both ends of the
  • DC- to-DC butt connectors onto the positive and negative wires.
• 18. Attach control panel wiring harness.
• Attach thermostat wires to control panel wiring harness. Black to black, white to white.
• NOTE: white wire is always to the left of the black wire. Be careful to not break these wires.
• Once unit is installed, test all connections between the power source and the unit for excessive heat during normal operations.

Congratulations! You’ve installed your Nomadic Cooling AC Unit!
