Ⅱ Before using the solar air conditioner, please read the Safety Information to avoid damage to the solar air

conditioner or other issues as a result of incorrect operation.

Ⅲ Please turn off the power to the solar air conditioner when not in use.

Ⅳ The correct installation and use will ensure the best performance from your solar air conditioner. Please

read the

Operating Instructions

before installation, maintenance and use.

Ⅴ The

Specifications

of your solar air conditioner and the

Operating Instructions

are subject to change

without notice.

Ⅵ The product is manufactured to International Standard Q/320581FSC001-2006

The Performance Characteristics of Solar Air Conditioners

 The Koolsola product uses solar thermal energy to improve the operation of the condenser thus

reducing the amount of electrical energy required for operation

 Once stability is reached, the compressor is only required infrequently. Service life is therefore

extended.

 The condenser is 10dBA quieter than conventional. The fan head uses an advanced off-center blade

fan and foam air duct. This results in higher performance and lower noise.

 The reverse cycle function enables economical heating on cold days  The design is elegant and graceful while practical.

It uses microprocessor control. The operation is convenient and simple. The solar air conditioner is also

provided with an automatic detection display system. You will feel comfortable and socially responsible with

our solar air conditioner.

1. There may be differences between the temperature set by the remote control (The air

conditioner will stop working when the room reaches this temperature) and that measured by the air conditioner. You can regulate the temperature you want by using the remote control.

2. The ability of the air-conditioner to reach the set temperature depends on the ambient

conditions in the room.

3. The displayed temperature on the remote controller is the set temperature.

4. The indoor fan has three speeds: high, low and breeze (breeze is set by the system

microcomputer automatically).

5. The remote controller should be aimed at the receiving window of the indoor fan unit which

will

send out a “beep” sound when the signal is received.

2. Preparations before Operation

2-1 Usage of Batteries

1. Remove the back cover of the remote control by sliding in the direction of the arrow.

2. Fi t two AAA size 1.5V batteries check the polarity.

3. Replace the back cover.

2-2 Operation of the Remote Controller

Aim the controller at the signal receiving window of the indoor unit. There should be nothing between the remote controller and the signal receiving window. Avoid violent bumping. Avoid direct sunshine, heater and other heat resources. The remote controller should be kept clean and dry. Please use two AAA size 1.5V batteries with same brand. The batteries should be taken out if the unit isn’t used for a long period of time. Install two ne w batteries if the figures aren’t displayed clearly on the

LCD of the remote controller or the signal strength is low.

Always replace both batteries.

3. Operation Settings

Maintenance

Methods

Clean the remote controller Clean the intake vent grille

Use damp cloth with cold or warm water under 40 degrees. Rub the unit gently.

Rub it with soft cloth

Wash it gently with sponge and then dry. If it is very dirty, use diluted detergent

solution.

9 | P a g e

Clean the air filter (Recommended once every two weeks)

1. Hold the two ends of the

grille and pull it up-forward, then draw out the air filters downward gently (Do not shake them, or the dust will be released).

2. Use vacuum cleaner or water to clean. Dry them in shade after they have been washed.

3. Hold the two ends of the inlet grille, install the air filters according to the diagram, then shut the inlet grille.

Inlet grille

Air filter net

Raise it then pull it out downward

Raise it and install it into the

groove

When the machine is not used for a long period of time:

Run it to dry the inside of the machine.

Take out the batteries of the remote controller.

Switch off the power.

Operation Guide

In cooling mode, the temperature difference between indoor and outdoor should be within 5 degrees, for healthy living. Try to prevent outdoor heat coming in (Close the doors and windows and pull drapes) The air filters shouldn’t be blocked up, or they will lower the cooling efficiency. Adjust the vertical and horizontal air direction for greatest comfort. Do not let the cold air blow directly onto your body for a long period. Raise the fan speed for greater cooling efficiency. In heating operation, ensure the humidity of the room is monitored, or you will feel dry and uncomfortable.

Trouble

Shooting

Before calling a serviceman, please check the following:

Symptom

Possible reason

The air conditioner does not work

The electrical plug is not in the socket. The remote controller is not working. The voltage is too low (Brown out). The electricity was turned back on immediately after being cut off. The voltage is irregular during stormy weather, please pull out

the plug, restart the unit in 3 minutes.

The compressor stops working

In the drying operation, it works for 10 minutes, then stops for

5 minutes, repeats in cycles.

The room temperature has reached the temperarure set by

the remote controller.

In heating operation the unit die not produce warm air

The compressor is at delay stage (To protect the compressor,

there are several minutes delay for every start).

It has the ability to prevent cold air from blowing out,

please wait

for a moment after the compressor starts.

In defrost mode, hot air will be blown out automatically during

defrosting operation.

The efficiency of cooling or heating is low

The air filters are too dirty. The intake vent or outlet vent is blocked. In heating operation, the ambient temperature is too low. Repeatedly heat and defrost.

Attention: The dirt between the fins of the outdoor heat exchanger should be cleaned regularly (cut off the power supply before cleaning, be careful not to damage the cooling fins.)

Noise

Sounds like water flow?

-It is the sound of the circulation of refrigerant.

Sounds like air is condensed to leak out?

-In heating operation, at the beginning or end of defrosting, this is the sound of the back-flow refrigerant.

Abnormality of the remote controller display

The power of the batteries has run out. The batteries are inserted incorrectly. Take out the batteries and insert them again.

Cold water leaks from the air conditioner

Condensation will occur in the ai r outlet due to the temperature

difference.
