INSTALLATION INSTRUCTIONS AIRCOMMAND IBIS

ROOFTOP AIRCONDITIONER

Suitability:

The IBIS caravan rooftop aircondioner is suitable for installation on caravans

and motorhomes provided the roof structure is suitable and the installed position

allows for reasonable air circulation within the van.

A central installed position is recommended to allow for even air distribution

throughout the van. In difficult positions the airdistribution plenum may be set at right

angles to the fore/aft direction of the van

Fig 1

The installed weight of a unit is 46 KG and the roof structure must be strong enough

to carry this load. If in doubt always use an “H” frame to spread the load out to the

walls. See Figs. 1 & 2 for details.

\ INSTALLATION INSTRUCTIONS AIRCOMMAND IBIS ROOFTOP AIRCONDITIONER Suitability: The IBIS caravan rooftop aircondioner is suitable for installation on caravans and motorhomes provided the roof structure is suitable and the installed position allows for reasonable air circulation within the van. A central installed position is recommended to allow for even air distribution throughout the van.

Fig 2 The unit must not be installed more than 5 degrees out of level fore / aft. The 240 V 50Hz power supply must be protected with a 15 Amp circuit breaker. Installation: The unit requires a 356mm square hole (14” x 14” ). This hole must be boxed up all around and be structurally integral with the transverse roof members. The boxing up must isolate the airconditioner return air from the ceiling space. See Fig.
PAGE 3
Before installing the unit over the square hole, clean the roof around the hole to remove any grease etc. See Fig 4. Fig 4 Take the sealing gasket and strip off the backing to expose the self adhesive side. Lay the gasket over the hole and press down firmly. Apply silicone sealant around the outside edge of the gasket, and now the aircondioner is ready for installation over the hole. See fig .

Bolting down: NB: The maximum length of threaded rod allowable to be screwed into the unit is 60mm. The standard rods supplied are 100mm x 5/16” BSW. If the ceiling thickness is such that more than 60 mm will enter the unit, then the threaded rods must be shortened or replaced with a shorter type. Using an overlength rod may damage the evaporator assy within the unit. Installing the 4 clamp bars: See Figs 6 &7 Firstly engage the 4 threaded rods into the moulded in nuts in the base of the unit.

Fig 7 Connection of power supply: See Fig. 8 The power cable can now be connected via the terminal block located on the underside of unit.

Measure the distance from the fan discharge tube, after the unit is clamped down to the ceiling. This is dimension “A” Add 15mm which is the overlap distance of the extension duct over the fan tube. Extension duct length is therefore A + 15 mm = “D” Cut the extension duct to this length. See Fig 9 Fig 9 Fit the circular duct to the fan discharge tube engaging the notch over the fan cable.
PAGE 7
Now the duct can be engaged with the extension duct and pushed up firmly against the ceiling. NB the extension duct should fit snuggly into the foam seal at the base of the duct spigot. Note that there are two sets of holes provided in the duct to secure it to the ceiling. Select the holes that will pick up the timber framing around the hole. Using the screws provided, screw the duct to the ceiling ensuring that the duct faces fore and aft accurately.

Fig 14 Now fit facia to duct and screw the 4 securing screws up into the duct. Figs 12 , 13 & 14. Remove the return airfilters and drive fixing screws into the ceiling to ensure the facia fits snuggly against the ceiling. See fig 15 Fig 15 Refit filters.

Fig 16 Commissioning of the unit: (see also instructions to operate controls) Turn on the circuit breaker to energise unit. The unit may be controlled either with the swing down panel or the remote control. With the swing down panel: Unclip the swing down panel . (use a table knife or similar) See fig 17. Fig 17 Press “ON” pad.

Set temperature a few degrees below room temperature. Note: The digital readout = actual room temp. Press down or up arrow the readout will blink out the set point and then return to room temp. The fan will start immediately and the compressor will start after a 3 minute delay. Check unit runs OK and cools. OPERATING INSTRUCTIONS Turn the unit on by pressing the ON /OFF button once Press the MODE button to cycle through options Cool, Dry, Heat , and Fan.
PAGE 12
After the delay, the compressor will start. Usually the fan will stop and will not re energize until the heat exchanger has warmed and then the fan will start to blow warm air. The DRY mode is used when the room temperature is close to comfortable but you wish to dehumidify. Press MODE button to highlight DRY. Set the temperature to desired setpoint. NB: The fan speed is locked in LOW. The compressor will cycle on and off at approximate intervals of 6 minutes to extract moisture from the air.

OPERATION USING THE REMOTE HANDPIECE: Be sure to point the signal transmitter at the main control on the plenum. All functions are available as per the main control.
