INTRODUCTION

Hello and congratulations on

® purchasing a Braemar Ducted

Cooler for your home.

®

Braemar coolers have been designed to provide quiet, reliable and cool comfort.

Please take a few moments to read these operating instructions, so that the most can be gained from this investment.

®

Braemar coolers are fitted with a

Wall Mounted Control. Please refer to the relevant section in this manual for instructions on how to operate the system. Also, please be aware of the components and features that are fitted to your particular cooler.

Effective Cooling

To provide efficient cooling or ventilation the building must have sufficient exhaust openings to the outside of the building. To assist air flow, open windows and doors that are farthest from the outlet vent in each room. In these rooms, provide an exhaust opening about 2 times the vent size of the room.

At Seeley International we

® manufacture Braemar evaporative coolers from the highest quality materials, and we have designed the product to provide many years of economical, trouble free cooling.

Where the design of the building prevents adequate exhaust, consideration should be given to the provision of mechanical extractions, such as an exhaust fan.

Important Notes!

In areas where temperatures can cause water supply pipes to freeze, a drain down facility should be provided during the installation. This drain down facility must be activated prior to freezing conditions, to avoid possible damage to the cooler components.

Keep these instructions in a safe place for future reference.

The appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning the use of the appliance by a person responsible for their safety.

Power Outages

If the power in your home is interrupted the cooler will retain its current settings.

That is, it will stop for the time the power is off but resume operation when the power comes back on again.

Health Regulations

In some states, regulations require that evaporative air coolers be serviced at specific intervals.

WALL CONTROL FUNCTIONS

Two Speed and Variable Speed Units.

Your evaporative air conditioner has control switches to provide for the benefits of fresh air ventilation and cooling at high and low air flows.

There are two types of control switches available:

Two Speed (Fig. 1) and Variable Speed (Fig. 2).

Your control panel offers independent control for the fan and cooling functions.

To Start the Air Conditioner

(1) Switch the COOL control on.

(2) Turn on the AIR (fan) control and using the SPEED switch (HI/LO switch or Variable knob), select the fan speed you require.

ILL768-A

When ventilation only is required (air flow with no cooling) turn the COOL switch off, and select the fan speed to provide the air flow you require.

To Stop the Air Conditioner

Switch the COOL control off, then switch the AIR control off.

Using Your Air Cooler

Evaporative air coolers provide very effective cooling by drawing outside air through filter pads saturated with water.

This water washes the air and cools it by the process of evaporation. There are a number of operating techniques and circumstances of which you should be aware to get the best performance from your evaporative air cooler.

To provide effective cooling or ventilation, the air cooler must be operated with sufficient openings to exhaust the air. For example: windows, doors or ducts. The location of the opening(s) will determine the pattern of cool air flow. The following are the minimum opening sizes required in square metres:

UNIT

EA90

EA120

EA 150

0.4

0.6

0.8

In light wind conditions more cooling can be obtained by opening additional windows and doors. In windy conditions close openings facing the wind.

Generally, openings opposite the supply vents are best. Some experimentation will soon show the arrangement most suited to your requirements. For a multiple outlet system, this is generally 1 (one) window opened 100 to 150 mm per outlet.

For a short time, when operating with new filter pads, you may detect an odour like

"wet timber”. This is the filter material becoming conditioned to use.

In many areas the water supply is quite hard. When this water is evaporated through the filter pads, the hardness is deposited as a scale on the pad. To reduce this scale build-up and to retain efficient filter pads a small amount of water is bled from the system.

The continuous drain of small amounts of water ensures that fresh water is added to dilute any build-up of scale or salts. The bleed rate for your air conditioner will depend on local operating conditions and will be adjusted during installation.

MAINTENANCE

To ensure that your air cooler continues to provide reliable service for many years, it requires some routine maintenance. There are two forms of maintenance:

(1) Pre and post season maintenance, and

(2) Routine preventative maintenance.

!

If water flow appears low, there may be a problem with foreign material clogging the pump or pump strainer. To correct, remove pump, dismantle base, clean and reassemble.

Pre-season Maintenance

!

!

Turn off the water supply.

Turn off the power supply.

!

!

Remove the filter pad frames. Insert a screwdriver into the slots at the bottom of the pad frames and lever upwards. Pull the bottom of the pad frames away, then lower the frames out of the cabinet (Fig. 3).

Turn off the isolating switch.

!

Hose both sides of the filter pads

CAREFULLY

(do not use excess water pressure as this may create "holes" in the pad material)

. Ensure that the woodwool pad material is evenly distributed, especially make sure that there are no gaps or holes at the TOP of the

PADS.

!

!

Check and, if necessary, clean the water spreaders located inside the roof above the filter pads.

Drain the water from the unit by removing the overflow or overflow bleed funnel.

!

!

!

!

Check pulleys for wear and correct alignment.

Check V belt for wear.

Thoroughly clean and dry the bottom of the water tank.

Replace filter pad frames. Ensure they are the correct way up.

Post-season Maintenance

!

Turn off the power supply to the cooler.

!

Remove pad frames

!

Turn off the isolating switch inside the cooler.

!

Remove pad frames. Clean them by hosing them with clean water, but do not use excess pressure because you might create holes in the pad media.

!

!

!

Remove and clean the special water

"spreaders" located under each edge of the top panel. Do not disconnect from water hose. When replacing them, check underneath to see that the spreaders are correctly located in the notches under the top panel.

Drain all the water form the cooler by removing the overflow or overflow bleed funnel.

Do NOT put it back until next season. Do not lose the O-ring seal.

Disconnect the water supply pipe from the tank. Make sure no water is left in the float valve.

!

!

!

Clean the bottom tank thoroughly.

Replace pads frames.

Cover the cooler for winter if desired.

MAINTENANCE

Routine Preventative Maintenance:

All units can benefit from routine preventative maintenance. This may be required more frequently if you are operating under harsh conditions, in adverse environmental situations, in very dusty areas or running for long hours.

WARNING

As your cooler is mounted on the roof, we suggest that any maintenance or checks be carried out by an authorised

Braemar dealer or service agent.

Climbing onto the roof can be hazardous and could result in injury to you and damage to your property.

We require that the following components and the operation thereof, be checked after the first year, then every 2 years as routine maintenance.

(1)...... Belt drive.

(2)...... Pump.

(3)...... Fan motor operation and current.

(4)...... Float valve.

Failure to carry out regular maintenance will affect your warranty coverage.

Check Your Local Regulations:

In some areas and for some commercial installations local regulations have specific requirements for the maintenance of evaporative air conditioning systems.

Generally these involve regular cleaning and maintenance at (3) monthly intervals or more frequently if necessary.

TROUBLESHOOTING GUIDE

It will not take long for you to get to know the features of your air conditioner, but in case you encounter difficulties here are a few hints to help keep you cool:

PROBLEM

Inadequate cooling.

POSSIBLE CAUSE

Dry pads, or lack of water while air conditioner operating.

SUGGESTED REMEDY

Check that the tap is turned on. Check pump and pump strainer. Check water distribution systems. Ensure pump (COOL) is turned on.

Insufficient air discharge openings to allow air to exhaust from areas being cooled.

Pads shrunk away from the top corners (woodwool pads only).

Adjust door/window opening.

Tease the woodwool out evenly or replace pads.

Air restriction in ductwork.

No air flow.

Clogged or dirty filter pads.

Call Dealer to investigate and rectify.

Clean or replace pads.

Circuit breaker tripped or unit fuse blown.

Replace the fuse specific to that unit.(See Braemar

Installation Manual).

Broken fan V belt Replace V belt.

Air flow, but not cool.

Electrical fault.

Insufficient water reaching filter pads.

Pump failure.

Call Service (see Rear cover).

Ensure water supply to unit is turned on.

Clean pump filter.

Call Service to repair.

Fan stops and then restarts.

Motor overload.

Continuous overflow of water.

Float valve adjustment.

Incorrect bleed rate.

The fan motor is fitted with an automatic thermal overload protector which will be reset when the motor cools down. If the motor stops and starts continuously, it should be investigated for a fault by a qualified

Technician.

Adjust float valve.

Adjust bleed rate. Included on each bleed tray are plastic plugs with matching holes. With all plugs inserted, bleed rate is maximum. If you decide that the amount of bleed is too much, remove the plug/s from the bleed tray one at a time until the desired amount is achieved.
