SAFETY INSTRUCTIONS

This manual has safety information and instructions to help users eliminate or reduce the risk of accidents and injuries.

RECOGNIZE SAFETY INFORMATION

This is the safety-alert symbol. When you see this symbol in this manual, be alert to the potential for personal injury .

Follow recommended precautions and safe operating instructions.

UNDERSTAND SIGNAL WORDS

GENERAL INFORMATION

A. Product features or specifications as described or illus-

trated are subject to change without notice.

B. This Air Conditioner Is Designed For:

1. Installation on a recreational vehicle during the time the vehicle is manufactured.

2. Mounting on the roof of a recreational vehicle.

3. Roof construction with rafters/joists on minimum of 16 inch centers.

4. Minimum of 2.00 inches and maximum of 5.50 inches distance between roof to ceiling of recreational vehicle. Alternate installation methods will allow forroofs more than 5.50 inches thick.

C. The ability of the air conditioner to maintain the desired

inside temperature depends on the heat gain of the RV. Some preventative measures taken by the occupants of the RV can reduce the heat gain and improve the performance of the air conditioner. During extremely high outdoor temperatures, the heat gain of the vehicle may be reduced by:

1. Parking the RV in a shaded area

2. Using window shades (blinds and/or curtains)

3. Keeping windows and doors shut or minimizing us age

4. Avoiding the use of heat producing appliances

A signal word , WARNING OR CAUTION is used with the safety-alert symbol. They give the level of risk for potential injury .

WARNING

indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury .

CAUTION

indicates a potentially hazardous situation which, if not avoided may result in minor or moderate injury .

CAUTION

used without the safety alert symbol indicates, a potentially hazardous situation which, if not avoided may result in property damage.

Read and follow all safety information and instructions.

Operation on High Fan/Cooling mode will give optimum or maximum efficiency in high humidity or high outside temperatures.

Starting the air conditioner early in the morning and giving it a "head start" on the expected high outdoor ambient will greatly improve its ability to maintain the desired indoor temperature.

For a more permanent solution to high heat gain, accessories like A&E outdoor patio and window awnings will reduce heat gain by removing the direct sun. They also add a nice area to enjoy company during the cool of the evening.

D. Condensation

Note: The manufacturer of this air conditioner will not be

responsible for damage caused by condensed moisture on ceilings or other surfaces. Air contains moisture and this moisture tends to condense on cold surfaces. When air enters the RV, condensed moisture may appear on the ceiling, windows, metal parts, etc. The air conditioner removes this moisture from the air during normal operation. Keeping doors and windows closed when this air conditioner is in operation will minimize condensed moisture on cold surfaces.

When sizing the generator, the total power usage of your recreational vehicle must be considered. Keep in mind generators lose power at high altitudes

an dfrom lack of maintenance.

* For wire length over 24 ft., consult the National Electric Code for proper sizing.

** Dometic Corporation gives GENERAL guidelines for generator requirements. These guidelines come from experiences people have had in actual applications.

*** CIRCUIT PROTECTION: Time Delay Fuse or HACR Circuit Breakers Required.

INSTALLATION INSTRUCTIONS

A. Precautions

Improper installation may damage equipment, could endanger life, cause serious injury and/ or property damage.

1. Read Installation and Operating Instructions carefully before attempting to start your air conditioner installation.

2. Dometic Corporation will not be liable for any damages or injury incurred due to failure in following these instructions.

3. Installation must comply with the National Electrical Code ANSI/NFPA-70 and CSA Standard C22.1 (latest edition and any State or Local Codes or regulations.

4. DO NOT add any devices or accessories to this air conditioner except those specifically authorized by Dometic.

5. This equipment must be serviced by qualified personnel and some states require these people to be licensed.

b. For two unit installations: Install one Air Condi-

tioner 1/3 and one Air Conditioner 2/3’s from front of RV and centered from side to side.

FIG. 2

2/3L

1/3L

It is preferred that the air conditioner be installed on a relatively flat and level roof section measured with the RV parked on a level surface.

Note: A 8° slant to either side, or front to back, is acceptable for all units.

3. After Location Has Been Selected: a. Check for obstructions in the area where air

conditioner will be installed. See FIG. 4.

b. The roof must be designed to support 130

pounds when the RV is in motion. Normally a 200 lb. static load design will meet this requirement.

B. Choosing Proper Location For The Air

Conditioner

This air conditioner is specifically designed for installation on the roof of a recreational vehicle (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;

• Geographical location where the RV will be used;

• Personal comfort level required.

1. Normal Location-The air conditioner is designed to fit over an existing roof vent opening.

FIG. 1

2. Other Locations-When no roof vent is available or another location is desired, the following is recom-

mended: a. For one unit installation: The air conditioner

should be mounted slightly forward of center (front to back) and centered from side to side.

It is the responsibility of the installer of this air conditioner system to ensure structural integrity of the RV roof. Never create a low spot on the roof where water will collect. Water standing around the air conditioner may leak into the interior causing damage to the product and the RV.

c. Check inside the RV for return air kit obstruc-

tions (i.e. door openings, room dividers, curtains, ceiling fixtures, etc.) See FIG. 3 & 4.

C. Roof Preparation

1. Opening Requirements - Before preparing the ceiling opening, the type of system options must be decided upon. Read all of the following instructions before beginning the installation. If a roof vent opening will not be used a 14-1/4" x 141/4" (±1/8") opening must be cut through the roof and ceiling of the RV. This opening must be located between the roof reinforcing members.

There may be electrical wiring between the roof and the ceiling. Disconnect 120 volt AC power cord and the positive (+) 12 volt DC terminal at the supply battery. Failure to follow this instruction may create a shock hazard causing death or severe personal injury.

The 14-1/4" x 14-1/4" (±1/8") opening is part of the return air system of the Air Conditioner and must be finished in accordance with NFPA Standard 501C Section 2.7.2.

2. Roof Vent Removal a. Unscrew and remove the roof vent. b. Remove all caulking compound around open-

ing.

c. Seal all screw holes and seams where the roof

gasket is located. Use a good grade of all weather sealant. See FIG. 5.

FIG. 5

d. If the opening exceeds 14-3/8" x 14-3/8", it will

be necessary to re-size the opening to 14-1/4" x 14-1/4" (±1/8").

e. If the opening is less than 14-1/8" x 14-1/8", it

must be enlarged.

3. New Opening- (Installation Other Than Vent Opening) a. Mark a 14-1/4" x 14-1/4" (±1/8") square on the

roof and carefully cut the opening.

b. Using the roof opening as a guide, cut the

matching hole in the ceiling.

c. The opening created must be framed to provide

adequate support and prevent air from being drawn from the roof cavity. Lumber 3/4" or more in thickness must be used. Remember to provide an entrance hole for power supplies, furnace wiring and a seven-conductor cable, 18 to 22 AWG is to be used for analog thermostat

connections.
