Check the contents of the accessories supplied with your air conditioner as shown below:

• Air conditioners covered in this manual are designed for installation on an RV’s roof.

• Installation of this air conditioner must be in accordance with NFPA 1192 and NFPA 70.

• For proper installation, there must be a 14 3/8″ x 14 3/8″ (+/-1/4″) square opening in the roof and ceiling of the RV.

• There must be 2-6″ of space between the RV ceiling and the roof to accommodate our air division baffle.

• Air conditioners covered in this manual are designed to fit over preexisting roof vent openings.

• If a roof vent opening isn’t available, use the following guidelines:

  • Unit is to be installed centered side-to-side on the RV roof.

  • Unit is to be installed on a section of roof which is level with respect to the RV roof if parked on a flat, level surface.

  • Roof at the point of install can have a maximum tilt angle of 15° toward the front or rear of the RV.

Standard Height Models (GRC/GRH) TOP-DOWN VIEW

• 14-3/8 in width.

• Air inlet: 3/8 ± 1 1/2 in from front of unit, 4-7/8 ± 1 1/2 in from side, 14 ± 1 1/2 in from 3 sides (max).

• Air outlet: 3/8 in ± 1/4 from front of unit, 3-5/8 ± 1 1/2 in from side, 2 in max from rear, 1 in max from top and bottom.

Low Profile Models (PLCS/PLHS) TOP-DOWN VIEW

• 14-3/8 in width.

• Air inlet: 3/8 ± 1 1/2 in from front of unit, 5 in ± 1 1/2 in from side, 4 ± 1 1/2 in from side, 2 in max from rear.

• Air outlet: 3/8 in ± 1/4 from front of unit, 3-5/8 ± 1 1/2 in from side, 2 in max from rear, 1 in max from top and bottom.

1. Unscrew and remove roof vent from RV.

2. Seal all holes and seams with a weather resistant sealant.

3. Measure the width and length of the vent opening. If the opening doesn’t comply with the requirements from section A, it must be resized.

If a preexisting opening will not be used, a new opening will be cut through both the roof and ceiling of the RV.

1. This opening MUST be between structural roof members.

2. Do NOT cut structural roof members to create opening for this air conditioner. Doing so may cause damage to RV and air conditioner.

3. Do NOT create a low spot on the RV roof. Water can pool and may leak through the opening.

The square opening must be boxed with framing at least 3/4″ thick to withstand the load from the compression bolts.

Be sure to provide an access hole for RV wiring toward the front of the 14 3/8″ x 14 3/8″ opening.

Roof and RV structure at point of install must be strong enough to support air conditioner without any deflection. If in doubt, please contact your RV manufacturer. Deflection will allow water to pool at the air conditioner’s gasket, and may cause a leak.

These models require a 115V, 60-Hz protected with either a 15-amp or 20-amp time-delay fuse or circuit breaker (see table 1 on page 4).

Use a minimum of sheathed, 12 AWG copper wire with ground.

Be sure that 16″ of supply wire is passed through the framing. This ensures enough wire is available for an easy connection in the junction box.

LIFTING HAZARD. Ensure proper lifting methods and controls are used when lifting unit to the RV roof. Failure to do so can result in injury.

1. Remove unit from packaging and dispose of packaging.

2. Do not slide the unit on its mounting gasket. Damage to gasket can cause a leak. Using two people, lift the unit and place it over the prepared opening. The front of the unit must face the RV’s direction of travel. Damage to condenser fan and coil will occur if this instruction is not followed.

It is important that these installation instructions are read and understood before installation and use.

Failure to securely install the unit to the RV before moving the RV may result in personal injury or death.

Do not operate the unit or recreational vehicle until the unit is fully secured on roof.

3. Bring the ceiling assembly with all provided mounting hardware into the RV. If you are using an indoor assembly, all work on the exterior of the RV is now complete.

1. If your roof has two individual openings as shown in Section A, Figure 7, proceed to step 1A. Otherwise, proceed to step 1B.

   1A. You will need to install accessory RGRFG1A foam gasket to prevent the inlet and outlet airflows from mixing. Tilt your unit up and peel the adhesive release liner from the back of the RGRFG1A foam gasket. Adhere the gasket to the bottom of the unit’s base pan between the air inlet and outlet openings.

   1B. Tilt your unit up and position your baffle such that it separates inlet and outlet airflow without interfering with the ductwork in your roof opening. Then, set your unit back down, maintaining the positioning referenced in Section A.

2. Remove the outdoor shroud by unscrewing the 4 screws around the perimeter of the unit and place it off to the side.

3. Remove the EPP Evaporator cover and store it with the shroud cover. Pull the 115VAC and the 12VDC power supply cords as well as the thermostat wiring from the RV roof opening through the ovular air inlet opening at the front of the air conditioner’s base-pan.

4. Identify the indented areas in the lower piece of the evaporator EPP Cover. These 4 locations are where you will drive your lag bolts to secure the air conditioner to the RV’s roof.

5. If you are mounting into a wooden frame, use lag bolts rated for wood and torque to 35+/- 5 in-lbs. If you are mounting into an aluminum frame, use lag bolts rated for metal and torque to 35 +/- 5 in-lbs.

6. See the Control Use & Care Manual for connecting power, thermistors, and a thermostat to your control.

Features and appearance will vary.

Controls:

1. Power Off: The air conditioner is off in this position.

2. Air Conditioning Modes: In these positions, the compressor and fans will run to provide cold air. The three modes correspond to low, medium, and high fan speeds.

3. Fan Only Modes: In these modes, the fans will run to circulate air in the RV. The three modes correspond to low, medium, and high fan speeds.

4. Temperature Selection: This knob determines the room set point temperature. Turn this knob to increase or decrease how cold the air conditioner will make the room.

To prevent circuit breaker from tripping, wait a minimum of 3 minutes between turning the compressor off and then back on (i.e. wait 3 minutes before moving the dial from position 1A to 1B back to 1A or moving from position 2A to 2B back to 2A (pictured above)

• When you turn off the air conditioner, wait at least 3 minutes before turning it back on. This prevents the compressor from overloading. This 3 minute delay also applies when switching from cool mode to fan and back.

• Do not operate your air conditioner in the Cool mode when the outside temperature is below 60°F (15° C). The inside evaporator coil may freeze up, and the air conditioner will not operate properly.

Use the lever to open or close vent on face of control panel.

Open or close 4 side ports to adjust airflow from the air conditioner.

When your air conditioner is operating normally, you may hear sounds such as:

• Droplets of water hitting the condenser, causing a pinging or clicking sound. The water droplets help cool the condenser.

• Air movement from the fan.

• Clicks from the control cycling

• A hum or pulsating noise caused by the compressor cycling on and off.

Turn the air conditioner off and disconnect power from the air conditioner before cleaning.

To clean, use water and a mild detergent. Do not use bleach or abrasives.

The air filter should be checked every 2 weeks and cleaned if necessary.

DO NOT operate the air conditioner without a filter because dirt and lint will clog it and reduce performance.

Cleaning the Air Filter:

1. Turn off the air conditioner.

2. Remove the air filter cover per the following figures to gain access to the filter.

3. Use a vacuum cleaner to clean air filter. If the air filter is very dirty, wash it in warm water with a mild detergent. Do not wash the air filter in the dishwasher or use any chemical cleaners. Air dry the air filter completely before replacing to ensure maximum efficiency.

4. Reassemble the air filter to the grill.

5. Carefully reassemble the grill and filter assembly to the main panel.

6. Turn on the air conditioner.

RPREN and RPRED assemblies use a merv 6 filter which should be periodically checked and maintained to be debris free.

Your air conditioner needs annual maintenance to help ensure steady, top performance throughout the year.

Call your local authorized dealer to schedule an annual checkup. The expense of an annual inspection is your responsibility.
