FAQ

How many windows and doors do I need to have open for my evaporative air conditioner to work effectively?

For an evaporative air conditioner to work effectively, some windows or outside doors must be open, or some other form of ventilation provided. This is to allow the hot air to escape outside of the building. The best approach is to open the windows or outside doors that are the furthest away from the air conditioning vents or ducts. In the rooms with air conditioning vents, try to have an exhaust area of open window (or door) that is about twice the size of the vent opening. Note: when it’s humid and the air is very moist, evaporation levels are lower. This means that the cooling effect is reduced. In some situations, it may help to switch the air conditioner to “ventilation” mode and run the fan on a high speed. If you have tried all of the above and still feel your air conditioner is not working effectively, your air conditioner may need to be serviced.

Can I have lots of doors and windows open?

You can fully open windows, outside door and verandas, but you may experience a reduction in the cooling effect if too much hot air is let in. For best results, partially open windows or outside doors that are the furthest away from the air conditioning vents or ducts. In the rooms with air conditioning vents, try to have an exhaust area of open window (or door) that is about twice the size of the vent opening. If there are very hot winds, you can reduce openings on the windward side of the house (where the wind is coming from) and increase the openings on the lee (opposite) side of the house.

I’m concerned about the security of having my windows or outside doors open, what should I do?

If you are concerned about your safety it may be a good idea to have security doors and windows installed. Security doors and windows that allow air to pass through, but prevent entry to the home are a great way to give you peace of mind and the best results from your air conditioner. An alternative to opening a window or outside door is to install security vents, or up ducts, that exhaust the air from the building.

Can I use bore water in my evaporative air conditioner?

There are many thousands of evaporative coolers working on bore water in Australia. However, high calcium content bore water will affect the Service life of the filter pads and the unit will also need to be maintained more regularly than units operating on good quality water. We recommend you contact us to discuss measures to extend the life of your filter pads.

Why do evaporative air conditioning units drain water every now and then?

This is normal for evaporative air conditioning units it means your water management or Watermiser system is working correctly. These systems are designed to monitor and control the quality of the water in the tank. So, it only drains water when the system really needs to. It does this by bleeding off water down through the drain, which is replaced with fresh water via water inlet float valve as the water level in the unit drops.

The frequency at which the water manager bleeds off is determined by the quality of the water in the tank. A probe in the tank measures the water salinity (impurities) and, when this rises above a set level, the unit will drain some water.

The frequency at which the water manager allows water to bleed off is dependent on:

1) The water supply quality;

2) The temperature of the day;

3) The humidity of the day;

4) The wind of the day;

5) The fan speed the unit is being run at;

and 6) The size of the unit.

Why do evaporative air conditioning units drain the water when it has not been used?

When evaporative air conditioning units have the “no seasonal maintenance” feature / “Watermiser” / drain system fitted, then it will drain all the water out of the unit after a preset period of time (refer to your Owner’s Manual for details or contact us for more information). If your evaporative air conditioning unit does not have the “no seasonal maintenance” feature you may need to have your air conditioner serviced.

When and how should I clean my evaporative air conditioning unit?

We recommend that cleaning be carried out at the end of the summer season and at least once per year. Remember to only use clean water, as it does not leave a residue or odour. If the cooler is operating under harsh conditions, it may require a maintenance check more frequently.

For evaporative air conditioning units with the “no seasonal maintenance” feature, you do not need annual or end of season cleaning. However, the air conditioner will still require routine maintenance checks on an every other year basis. If the cooler is operating under harsh conditions, it may require a maintenance check more frequently. Always use clean water when cleaning the cooler, to avoid odours.

WARNING: As your evaporative air conditioning unit is mounted on the roof, we suggest that any maintenance or checks be carried out by appropriately trained and qualified personnel. Climbing onto the roof can be hazardous and could result in injury to you and damage to your property. Contact us for more information about our servicing options.
