  • Page 7: Dismantling The Air Cooler

    DISMANTLING THE AIR COOLER The air cooler is designed to be partially dismantled in order to reduce the weight for installation. COOLING PAD FRAME REMOVAL To remove the Cooling Pad Frame, first disengage the top clips of the pad frame using a screw driver as shown.

  • Page 8: Removing The Transition

    DISMANTLING THE AIR COOLER REMOVING THE VENTURI/FAN IMPORTANT! Ensure the motor plug has been removed from the control box before removing the venturi (see page 9 for removal of plug). With both arms hold each side of the Venturi/fan assembly. Press the large clips at each side and lift the Venturi/fan assembly upwards and carry it out of the cabinet.

  • Page 9: Installing The Transition

    INSTALLING THE TRANSITION The air cooler is designed to be fixed to the first section of the duct without any additional frame for support. Therefore make sure the duct is fixed to the building using a strong method. The duct size must be 550 x 550mm. The top edge must be strong without any flange .
  • Page 10 INSTALLING THE TRANSITION Use a spirit level in both directions to get the Transition level. Screw it to the duct using the eight (8) screws provided. There are eight (8) V-notch locations for the screws. See diagram. Now break off both clips on the Transition that retain the Weatherseal.
  • Page 11 INSTALLING ELECTRIC CABLES Disconnect the Electronics Module from the Water Tank by removing the screw under the isolation switch. See diagram. The switch cannot function with this screw removed. The installation kit supplied contains your power cable with ends ready to terminate and a wall control cable.

  • Page 12: Water Connections

    WATER CONNECTIONS You have the choice of installing the Drain Valve and water management system supplied, or not. If not, you need to install the Bleed Funnel alternative. See later note DRAIN VALVE ALTERNATIVE The function of the drain valve is to reduce the salts and minerals in the air cooler.
  • Page 13 WATER CONNECTIONS If you have installed the drain valve , then fit the float valve and solenoid valve to the air cooler as shown. Make sure all washers and o-rings are fitted correctly. Do not over-tighten plastic threads!! Make sure the Float Valve is centrally positioned and is free to move up and down.
  • Page 14 WATER CONNECTIONS Connect the solenoid cable (supplied in the kit) to the Solenoid Valve. Route the cable through the hole in the Transition. See diagram. The other end will be connected later. IMPORTANT: Make sure the cable does not interfere with the Weatherseal and that it will not be crushed by the Venturi/fan assembly.
  • Page 15 WATER CONNECTIONS BLEED FUNNEL ALTERNATIVE The bleed funnel is a simplified alternative to the drain valve. It also provides overflow and drain features. Assemble the bleed funnel to the Water Tank as shown. Make sure the o-rings are fitted correctly. Screw the nut tight by hand!! Attach the Drain adaptor under the...
  • Page 16 WATER CONNECTIONS After fitting the Bleed Funnel, then fit the Float Valve as shown complete with the Extension tube and 3/4” to 1/2” adaptor. See diagram. Make sure that all washers and o-rings are fitted correctly. Do not over-tighten plastic threads !! Make sure the float on the Float Valve is centrally positioned and is free to move up and down.

    ELECTRICAL CONNECTION Now the Electronics Module must be re- fitted. First take the wall control cable and the Solenoid Valve cable (if installed) that are loose in the Water Tank and route them out from the Electronics Module location, as shown.The cables must rest in the special channel provided.
  • Page 18 ELECTRICAL CONNECTION Lift the flexible cover on the Electronics Module. You will see some plug points. Connect the wall control cable to its correct plug point. If the drain valve, water sensor and solenoid valve are fitted then connect those cables also. Route the drain valve cable as shown before connecting it.

    INSTALLING THE FAN ASSEMBLY Carry the Venturi/Fan assembly to the air cooler and fit it back in place. It will only fit one way. Check that the two (2)clips are properly engaged.

  • Page 20: Installing The Wall Control

    INSTALLING THE WALL CONTROL WALL CONTROL LOCATION Install the Wall Control station about 1.5 metres above the floor in the place where you want the temperature to be controlled from. When selecting a position for the Wall Control station avoid the following locations: •...
  • Page 21 INSTALLING THE WALL CONTROL PLASTER BOARD OR BRICK WALL To mount the wall control on a plaster board or brick wall, use the template provided and drill the 16mm hole for the wall control cable and the (5mm Plasterboard or 6mm Brick) holes for the mounting plugs.
  • Page 22 INSTALLING THE WALL CONTROL Pull the wall control cable through the large hole and wall plate, remove the protective tape and plug the cable into the wall control. Feed the excess cable back into the hole and slide the wall control over the protruding bracket tabs.

  • Page 23: Set Up For Bleed Funnel

    PROGRAMMING THE WALL CONTROL To enter the programming mode, the procedure must be started within four (4) minutes of power being applied to the wall control. If this time has elapsed then turn off power to the air cooler for a minimum of 6 seconds before starting the following procedure.
  • Page 24 PROGRAMMING THE WALL CONTROL DRAIN RATE ADJUSTMENT If you installed the drain valve then the water will drain when the sensor detects that the water salinity is too high. Alternatively and if necessary, the air cooler can be set to replace some water after a set time of cooling operation with the following procedure.
