GENERAL INFORMATION

PURPOSE
This Cave Wave Air Command air conditioning unit is designed for installation on the roof of a recreational vehicle, trailer, or a truck to provide cooling for your vehicle.

• The roof must be capable of supporting the weight of the unit which is 75lbs.
• The absolute minimum thickness of the roof must not be less than 1 inch (25mm).
• The maximum thickness of the roof must not exceed 5 inches (125mm).
• Trimming of the duct work and/or bolts may be necessary depending on the roof thickness.

It is important that the unit is installed properly and according to the recommended guidelines.

ENSURING EFFECTIVE OPERATION
The effectiveness of the air conditioner is dependent on several factors e.g. size and heat load of the vehicle. When a Cave Wave unit is installed, Cave Wave assumes that thevehicle is well insulated with 1 inch (25mm) foam minimum in all walls and roof, that the windows are of moderate size (preferably double glazed) and the roof vents are airtight when closed.

Other methods of reducing heat load include:

• Closing all doors, hatches, windows and blinds
• Turning off appliances that might increase the heat load
• Ensuring the vehicle is parked in a shaded position. In periods of extremely high temperature, it’s recommended to start the air conditioner earlier in the morning to greatly improve its ability to cope with the expected high heat load.

CONDENSATION
In areas of high humidity, the humid air within the RV will cause “sweating” or condensation in parts of the unit as the humid warm air contacts the colder air discharge system. If this occurs please ensure the following:

• Closingall doors, hatches, windows and blinds to limit theingress of warm humid air.
• Increase the Fan Speed to increase airflow and reduce the condensation.

Main Components
The unit comprises various components including the air distribution box, roof unit, and more. Ensure proper positioning and clearance as specified in the manual.

Ensuring Effective Operation
To ensure optimal performance, factors like vehicle insulation, window types, and heat load need to be considered. Proper insulation and minimizing heat load will enhance the air conditioner’s efficiency.

Condensation Management
In high humidity areas, condensation may occur. To reduce this, ensure proper ventilation by closing doors and increasing fan speed to enhance airflow and minimize condensation.

Unit Installation
Follow the detailed instructions provided in the manual for installing the Cave Wave air conditioner on the roof of your recreational vehicle, trailer, or truck. Pay attention to roof thickness, weight support, and necessary trimming of duct work and bolts. Before beginning, mark out the position of the unit considering the following important re- quirements:

• The air conditioner should be situated as ascentrally as possible on the vehicle, to ensure even air distribution.
• The front of the unit MUST face the direction of travel; failure to follow this instruction will result in damage to the condenser fans.
• When considering the installation position remember to check for clearance around the plenum inside the vehicle.
• Avoid an installation position where a bulkhead, cupboard or light fitting could interfere with the discharge air flow from the plenum.

CAUTION

• Contact Cave Wave if your installation differs significantly.

ASSESS ROOF STRENGTH

• The roof members MUST be strong enough to support the weight of the unit 75 lbs without any roof deflection that will cause”pooling” of water around the unit. Contact your RV manufacturer to confirm the max load theroof is able to handle. If in any doubt considerthe use of an external “H” frame.
• If the roof does not have an existing hole one must be cut.
• Contact your RV manufacturer for the best method to cut through the roof.
• The square hole in the roof (14″ x 14″) MUST be boxed up with the gasket to provide a structure strong enough to withstand the compression of the installation bolts. This is also to ensure that air is not drawn from the roof cavity (Fig 3 & 4).
• Longitudinals MUST be fixed securely to the transverse roof members to transfer load (see Fig 3).

WARNING
There may be electrical wiring located between the roof and ceiling. Ensure that power is properly disconnected at the supply (mains and/or battery). Failure to do so may result in personal injury or death

TIP: Always use crawl boards across the roof to avoid damage

POSITION UNIT ON ROOF

• Remove the air conditioner from the carton.
• Position the unit over the gasket so that the corners of the square hole in the RV roof line up with the corners of the square hole underneath the air conditioner.

TIP: Have one person inside the RV looking through the hole while the other is on the roof adjusting the position of the unit.

CUT FROM THE ROOF

• If the roof does not have an existing hole one must be cut.

To layout locations measure from references that are identifiable from both inside and outside. Use the gasket as a template to find a location between the crossbeams.

NOTICE: Crossbeams may not shown on the outside of the rooftop.

• Under the roof, use the gasket as a template to mark the inner edge of the gasket to draw a 14″ x14″ square, and drill four indicator holes in each corner of the square.
• On top of the roof, use the holes as a guide to line up the gasket, and trace around the edge again. Use tape to mark, and follow the trace lines cut through the ceiling.
• Tossed the cutout and used a hand file to deburr the edges.
• Spray paint on the perimeter to seal up the exposed metal and side.

NOTICE: Stay well clear of tanks, fuel lines, and wiring.

NOTICE: Be careful cutting the top. The steel is thin and unbraced enough that the blade will try and pull it to flex or bend.

TIP: Always use crawl boards across the roof to avoid damage

• Clean the mating surface, lay down thick adhesive sealant, and then place the gasket on the top and position it correctly around the hole.

NOTE: Laid down sealant carefully, and selected goop that is non-reactive to the metal roof.

CAUTION
The unit weights approximately 75lbs. Ensure a two person lift or use a mechanical hoist to avoid the risk of injury.

• DO NOT slide the unit on the roof, this may damage the gasket and result in leaks.
• Grab the bottom two sides of the unit to lift it, and place it over.
• Four M8 mounting holes on the chassis underneath the air conditioner will line up with- the corners of the square roof hole.

ATTACH ADAPTER TO UNIT

• Screw adapter to the underside of unit with the 4 screws provided (this step can also be done before the unit is positioned on the roof but be careful not to damage it while fitting)

WARNING
Ensure that power is properly disconnected at the supply (mains and/or battery). Failure to do so may result in damage to the unit and personal injury or death.

CONNECT ELECTRICAL SUPPLY
Installation must conform to local wiring codes and regulations or, in the absence of local codes, the Standard on Recreational Vehicles, NFPA 1192. and National Electrical Code NFPA 70.

ASSEMBLE DUCT

• Thread a hold down bar onto the M8 bolt and push the bolt almost all the way into the hole in each corner of the brace.
• Leave a gap between the hold down bar and the recess in the plastic brace. This will allow for easier engagement with the four corresponding threaded holes in the unit.
• Turn the assembly over and add the extension duct to the top of the assembly if needed.
• Avoid tearing or ripping the duct apart.

CAUTION
When attaching the duct to the unit take care to ensure it forms a tight, unbroken seal that doesn’t allow discharge air to escape.

ATTACH DUCT TO UNIT

• Raise the brace assembly and slip the extension duct over the outside diameter of the adapter underneath the rooftop unit.
• Engage and tighten the four M8 bolts with the threaded inserts in the rooftop unit.
• Recommended tightening torque of the bolts is 7 N.m (5.2 lb-ft). As a rough guide the bolts should be tightened so that the unit compressesthe roof seal gasket to approximately half its height.
• As the bolts are tightened ensure that the hold down bars slot into their recesses in thebrace.

CAUTION
When attaching the duct to the unit take care to ensure it forms a tight, unbroken seal that doesn’t allow discharge air to escape.

ATTACH PLENUM COVER -Secure the
main plenum cover to the duct assembly with the 6 screws provided (see picture).TIP: It is important that these screws are not over-tightened otherwise the plenum may crack.

• Place the air filters by sliding them into the plenum until they click into place
• Attach control panel, place the panel by pushing them into the air filters until they click into place
• Your installation is now complete.

MAINTENANCE

PLENUM FILTERS
The plenum filters are the only parts that require routine maintenance. They must be cleaned periodically to ensure that they do not become clogged with dust and other particles and are not covered by Warranty. The state of the filters can be ascertained from its appearance; the filters are translucent, and if they appear clogged, then they should be cleaned. Generally, the filters can be cleaned sufficiently by tapping them together to shake loose the dust and particles trapped inside. If a more thorough cleaning is required, then the filters can be washed out using warm, soapy water. Care must be taken to avoid ripping the fabric. The filters should be cleaned every two weeks or more when in use. Prolonged use, higher concentrations of airborne particles, and various other factors may result in the filters needing to be cleaned more often.  Replacement filters can be ordered directly from Cave Wave.

MOUNTING BOLTS
Cave Wave suggests that the hold-down bolts are initially checked for tightness within the first three months of installation and thereafter every 12 months if the vehicle is in constant use.

WARNING
Airborne particles can pose a health risk, particularly to young children and the elderly. Ensure that filters are cleaned in a safe and well-ventilated area.
