Frequently Asked Questions - Paradigm LCQ 250 Braemar

How do I switch between Automatic and Manual modes?

Press the AUTO button on the wall control until 'Auto' or 'Man' appears on the display.

What does 'Pre-Cool Cycle' mean?

When starting the cooler after a long idle, the display flashes 'Pre Cool Cycle'. This means the water pump is saturating the cooling pads for a few minutes before the fan turns on, ensuring only cool air enters your home.

How do I set a timed automatic start?

With the cooler off, press the TIMER button. 'Starting in' appears. Use ▲/▼ to set hours (up to 24). Press TIMER again to confirm. The cooler will start after that delay.

Why is my cooler not cooling enough?

Possible causes: dry pads (check water supply), insufficient exhaust openings (ensure at least 2.0 m² open to outdoors), or high ambient humidity. Increase fan speed or switch to Cool mode.

How do I drain the cooler manually?

With the wall control off, press and hold ▲ and ▼ simultaneously for 1 second. The display shows 'dr' confirming the drain operation has started.

What maintenance is required at the end of summer?

Turn off power and water. Remove pad frames, clean tank and pump filter (if no auto drain). Check pads and replace if worn. For auto drain models, no manual draining needed but still inspect.

What should I do if the wall control flashes 'Service'?

Ensure water supply is on and drain pipe is not blocked. Turn off the wall control and note the number displayed. Quote this number to your service agent. Contact Warranty Service at 1300 650 644.

Can I use the cooler without cooling (ventilation only)?

Yes. In Manual mode, press the COOL button until 'Vent' appears on the display. The fan will circulate fresh uncooled air.

How often should I replace the cooling pads?

Pads should be inspected before each summer season. Replace them if they are damaged, clogged, or deteriorated. Typically every 1-3 years depending on usage and water quality.

What exhaust opening size is required for my LCQ 250?

The manual specifies a minimum total exhaust opening of 2.0 m² for model LCB250 (equivalent to LCQ 250). An average door is about 1.5 m², so you may need additional windows or vents.

INTRODUCTION INTRODUCTION

Congratulations on choosing a new Braemar cooler for your home.

Your cooler is built from the highest quality materials and engineered to provide many years of economical, trouble free cooling.

Please take a few minutes to read these instructions so you have a full understanding of how to operate your cooler. Your installer should demonstrate the features and procedures set out in these instructions. The installer should also provide you with a Model and Serial number, which can be filled out on the last page.

Keep these instructions in a safe place for future reference.

EFFECTIVE COOLING

To provide efficient cooling or ventilation the building must have sufficient exhaust openings to outdoors in the form of doors, windows or other vents. To assist air circulation, open windows or doors that are furthest from the outlet vent in each room. In every room that has an outlet vent, provide an exhaust opening about 2 or 2.5 times the vent size of the room. Where the design of the building prevents adequate exhaust, consideration should be given to the provision of mechanical extraction such as an exhaust fan.

Total minimum openings for the whole building are demonstrated by the following table:

Cooler Model	Exhaust Opening
LCB250	2.0m2
LCB350	2.5m2
LCB450	3.0m2
LCB550	4.0m2

Please note that an average size door is 1.5m² .

The POWER button turns the cooler on and off.

There are two modes of operation to choose from, Automatic mode or Manual mode. When the cooler is turned on, it will start in the mode of operation it was in when last turned off.

If your cooler has not been operated for a while, then when you start it, "Pre Cool Cycle" may sometimes flash on the display as shown. This indicates that the water pump will operate to saturate the cooling pads for a few minutes before the fan is turned on. This is to ensure that when the fan starts, only cool air enters your home.

You can experiment with the settings on your wall control. This is the best way to get the most from your cooler.

DRAIN VARAMAND ALVERANATE BLOOD SYSTEMTIVE BLEED SYSTEM

This cooler comes with an automatic drain valve or an alternative simplified bleed system.

AUTOMATIC DRAIN VALVE

If the drain valve was installed instead of the alternative bleed system then your cooler will automatically drain during operation when the water salinity becomes too high. This ensures the water is always fresh and helps maintain your cooler in good condition to ensure optimum cooling performance. The frequency of the automatic drain may have been adjusted by your installer.

When the cooler is turned off for 72 hours, the drain valve will open automatically and empty water from the cooler. When the cooler is turned on again, fan operation will delay for a few minutes while the tank refills and the cooling pads are saturated again.

At any time when the wall control is OFF, you can drain the cooler by pressing and holding ▲ and ▼ for 1 second. The display will show "dr" to confirm the operation has activated.

ALTERNATIVE BLEED SYSTEM

During operation, the bleed system will drain small amounts of water. This ensures fresh water is continually added to dilute salt accumulation in the water caused through evaporation. This helps keep the cooler in good condition and ensure optimum performance.

The bleed rate will depend on local operating conditions and will be set by the installer.

Draining water from your cooler at the end of the summer season is not required if your cooler is fitted with an automatic drain valve. However, it is a requirement to check the cooler, it's operation, the pump, drain valve, solenoid and fan motor after the first year, then every two (2) years as routine maintenance. If the alternative bleed system is installed then maintenance should be conducted before and after every summer season as outlined below.

WARNING: We recommend maintenance is carried out by an authorised service agent. Climbing onto the roof is hazardous and can result in personal injury or property damage. Failure to carry out maintenance will affect your warranty coverage.
