REMOVAL OF PAD FRAMES

To remove a pad frame, insert a flat screw driver tip into the slot as shown and lever until disengagement occurs. Take hold of the pad frame and pull it towards you until the internal side clips disengage. Pivot the pad frame outwards and lift up. Take care not to damage the pad. Repeat these steps for the remaining pad frames. (Fig. B)

PRE-ASSEMBLY INSPECTION

!

Check that the correct cooler has been supplied. The cooler should have the following parts:-

(Check the parts are inside the cooler by removing a cooling pad frame.)

UNPACKING THE COOLER

Cut and remove the shrink wrap from around the cooler. Using 2 people, carefully lift the cooler up and away from it’s skid (Fig 1).

1

REMOVING PAD FRAMES

Firstly remove the corner clips, which are located above the top louvre and third louvre from the bottom on all corner joins. The clips will require a screw driver to aid removal.

Each frame is clipped into the cooler and is removed by use of a medium sized screwdriver. Insert the screwdriver into the small slots at the top of the frame and lever upwards until the clips disengage. The frame is now free to be lifted out of the cooler cabinet (Fig.2).

2

REPLACING PAD FRAMES

Ensure the pad frame is the correct way up by checking that the louvres face upwards. Fit the frame in at the bottom along the edge of the pan and rotate it in at the top. Take care not to damage the Chillcel as the frame approaches the plastic water spreader under the top panel. Then two sharp hits by hand should locate the frame into its correct location under the top panel. Replace the pad frame clips at the corners

COOLER LOCATION

Check the proposed cooler location first, to ensure it is structurally capable of supporting the weight of the cooler. Polymer coolers are lightweight but they require adequate support. The largest cooler in the

EXH range is about 185 lbs (84 Kgs).

Always locate the cooler where there is a plentiful supply of clean fresh air, and not in a recess or close to the ground where the air may be dusty or polluted.

Keep the cooler away from heater flues, exhaust vents (especially kitchens) and sources of ignition.

Avoid dangerous situations.

Allow for adequate, SAFE access around the cooler for maintenance, especially for pad cleaning, water connections, electrical connections, drain connections.

It is mandatory that water cannot enter the building as a result of poor sealing

(caulking or flashing) of the various penetrations into the building (ducts, necks, water pipes, electrical conduits).

The cooler must be mounted at least

10ft (preferably 15ft) away from the closest element of any TV antenna.

Make sure the cooler is not between the antenna and the transmission tower that is providing the television signal to the home. Ensure that all antenna cables are at least 10ft from the cooler.

NOTE!

It is recommended that a strip of foam or sealant is applied to the upper flange on the roof jack before securing the cooler to provide an airtight seal.

Ensure that the top of the roof jack is level, then check the lip of the pan for level when the cooler is in position on the roof jack. (Fig. 5)

5

RAISING COOLER TO IT’S

FINAL LOCATION

HANDLE WITH CARE. DO NOT DROP.

For lifting or pulling the cooler, always apply the ropes around the full cabinet or the fan housing and NEVER tie them to any of the four corner posts.

3

MOUNTING THE AIR

COOLER.

Handling and installing the cooler is always much easier if you remove the pad frames first.

WARNING!

Take care when moving the cooler that nothing is allowed to penetrate into the discharge opening (such as the end of a ladder), as damage may occur to the internal cooler components. If a ladder is used as a slide for the cooler to be pulled onto a roof or platform, we strongly recommend the cooler be turned upside-down first. Protect the lid from scratching.

International - Never drain the water directly on to the roof (This applies to all types of control/drain systems).

Assemble drain valve as shown (Fig

15).

Make sure that the o-ring is fitted before placing the drain valve into the hole. Screw the nut up tightly by hand underneath the cooler. Do not over-tighten. Now connect the cable

(Fig 15, item B) to the electronic module.

The drain adaptor allows the attachment of a ¾" drain hose to run water to a waste point. Attach it to the drain valve fitting underneath the pan by using the drain nut. (Fig. 16)

OPERATING ADJUSTMENTS

Water level

:

The water level in the cooler is important. Adjust the level at the float valve inside the cooler. Rotate the large plastic float CCW or CW to change the level. CW will lower the level; CCW will raise the level. (Fig.

17)

NEVER ADJUST THE WATER

LEVEL WITH THE COOLER

RUNNING

because the residual water in the pads and pipes will cause the water to over flow when it runs back into the pan.

Water level should be about ¼" above the float valve support shelf.

(Fig. 18)

after making connections and clamping the conduit cable.

Ensure that all electrical connections are tight. Loose connections will cause overheating that may lead to machine damage or fire.

Replace all covers on completion of the work, using only the screws supplied.

Do not tamper with factory wiring.

Before leaving the job, a trained, licensed technician must check that the cooler is operating correctly.

ELECTRICAL INSTALLATION

The cooler requires a split phase 240V,

60Hz power supply.

In the termination box connect:

- Phase 1 to the black wire

- Phase 2 to the red wire

- Earth to the green wire

The electronic module is factory sealed; do not attempt to open it; there are no field serviceable parts inside

The electronic module contains plug receptacles for fan motor, water pump, and other optional features if used.

This cooler contains an electronic module with main power supply termination box separated and connected via a cable and plug assembly.

The main power termination box is provided to facilitate easy wiring connections. Cable glands are provided for ½" ID conduit. (Fig. 19)

Running the Wall Control Cable

Plug the Wall Control cable to point Fig

22 “M” on the electronic controller. Run the cable to the roof space and then to the controller via the mains power cable entry point and plug to the rear of the

Wall Control.

Sub-circuit wiring must be rated at cooler rated amperes or higher, and must be protected by a suitable fuse or circuit breaker. Sub-circuit cables are to be double insulated all the way into the main power termination box.

WARNING!

When retro-fitting the cooler to an existing installation always turn off the electrical power at the source of the wiring.

DO NOT

TAKE RISKS!

Turn off and tape over the circuit breaker or remove the fuses and keep them with you until the job is complete. Set cooler, isolator switch, wall switch, motor and pump to "off".

Be sure to tell other occupants of the building what you are doing.

WARNING!

Check to be sure that the voltage rating of the cooler matches your electrical system voltage.

The electrical installation must be carried out by a licensed and qualified electrician.

INSTALLING THE MAIN

POWER CABLES

The point of entry into the cabinet of the cooler is by knockouts in the pan.

Seal the gap between the conduit and knock-out hole with silicone sealant

INSTALLING THE RECEIVER

Note: The following section describes installation of the receiver, which requires positioning of the receiver external to the cooler, inside the attic or below the ceiling. The supplied receiver lead is 16’ (5.0m) long, sufficient to reach into the attic or below the ceiling, from the cooler electronic module.

Other Options for Mounting

Receiver

The standard installation arrangement will satisfy the majority of applications.

However you may find difficult cases as follows:

Signal Problems

For signal problems in houses with a metal roof, position the receiver as close as possible to the metal roof with the antenna pointing directly away from the roof (Fig 26).

Flat Roof Installation

Where the installation is on a building with a flat roof and the attic space is less than 4’ (1.2 metres) deep, alternative mounting locations may need to be found for the receiver.

For example, install the receiver below the ceiling in the top of a nearby cupboard.

Do not wrap any excess receiver cable around the receiver. Do not extend the receiver cable.

(remote control)

ILL239-D

Aim to secure the receiver away from the ductwork, but as near as possible to the location of the remote control.

LOCATING THE REMOTE

CONTROL

The remote control should be placed approximately 5 feet (1.5 metres) above the floor, in the most used room in the home. This will give the optimum temperature sensing and operating position for the user.

For installations where the roof is framed in steel, position the receiver between the metal joists keeping the antenna as far away from metal joists as possible and directing the antenna perpendicular (right angle) to the joists will give the best results.

Placement is critical for correct functioning of the thermostat

(incorporated in the remote control).

The following points must be taken into consideration:

• Avoid direct sunlight exposure.

• Avoid mounting on external walls.

• Avoid mounting the remote control near heat sources such as stoves and televisions.

For most installations, mounting the receiver to the roof rafter as shown

(Fig 26) will provide satisfactory performance.

Important:

The orientation and position of the receiver may affect the receiver's performance. Other factors that may also influence performance are:

(1)...........Shielding from metal in the attic lying between the receiver and

Remote Control. This may include

Sisalation/sarking (foil sheets), and ductwork.

(2)...........Reflections from metal around the receiver.

SENSOR

Remote Control

(3)...........Interference from nearby transmitters (e.g. mobile phone, AM radio, Television, RF security systems).

SETTING THE ADDRESS

CODE

The Breezair electronics module will automatically recognize the remote control connection, provided the address code has been correctly set.

This is simply achieved by fitting the batteries into the remote control

within 4 minutes after turning on the main power at the electronics module.

The screen will stay blank for 5 seconds then display “Id” for 1 second. The communication address code will take a few seconds to set, then the remote control can be turned on. (Fig. 28)

If communication cannot be achieved, the power to the cooler will need to be turned off, and the batteries need to be removed from the remote control. Wait until the screen goes completely blank, then repeat the above procedure.

COMMISSIONING USING THE

REMOTE CONTROL

Take the remote control to the roof and control the Cooler from there. This will save you a lot of time.

The "Red (bottom) LED" indicates the status of the WaterManager measurement circuit and will function as follows:

Power up the cooler using the on / off switch on the Electronics Module. Test motor and pump operation. Look at the front of the Module where 2 light emitting diodes (LEDs) are situated

(Fig. 22 I & J). The top LED is

“tricolour” and can glow green, red or amber. The bottom LED is red only. If the top LED (Fig. 22, item I) is double flashing green, everything is OK, this is normal operation.

The following information allows quick diagnosis at start up -

The "Tricolour (top) LED" acts as a general diagnostic indicator, and will function as follows:

1 Flash

indicates

....WaterManager is operating and the measured salinity is below the set point.

2 Flashes

indicates

....WaterManager is operating and the measured salinity is above the set point.

3 Flashes

indicates

....The Salinity Control Method = Drain every 65 minutes.

4 Flashes

indicates

....Incorrect Salinity Control Method selected.

• Green double flash every 2 seconds indicates the control is running normally.

If it does not glow at all, then there is either no power to the Electronics

Module (check isolating switch, circuit breaker, plug and socket connections), or a failure has occurred.

Continuously On

indicates:

The probes are open circuit, or measured salinity is less than 20us/cm

(the water is very pure, ie has very little salt content).

DIP SWITCHES

There are 2 rows of DIP switches located under the battery cover on the remote control.

• Amber for 1 second ( remote controls only) indicates that the

Electronics Module has received a command at an incorrect ID address.

WARNING: Do not alter DIP switches 1 to 8 on top row and 7

& 8 on bottom row as the cooler will cease to work.
