Heya Mark,
Fujitsu air cons are factory set at 18degs you cannot change it without going through all the controller programs. Normally air cons are serpose to run around the 20deg point, is the air con not running effectually or do you just really like it cold.

I could check with tech help and see if I can send you the derictions of changing the minimum set point but it will not be good in the long run for your unit

    Hey again Mark,
    Okay the air cons dont read the temp from the controller they read it from the return air at the unit. 18 is very cold and you should make sure that the unit is sized at the right size. If you give me the room size with the amount of windows and such i will make sure the unit is the right size.
    Do you have any type of thermostat in your house that you can read the supply air from the air con?
    If you can get me some air measurements I should be able tell if that air con is working, because 18 is very cold :P

    check the air temp comming out of the vents. If it is around 16 to 13 deg then the ac is working fine. It may be under sized. area of room x 150watts/ sqare mt eg. 9sm x 150= 1350w / 1000 = 1.3kw

Right above the 'CLOCK ADJUST' there is a small hole, you need to push a ballpoint pen or something into that hole, to allow you to set the clock using the - and + buttons next to it. Then press the pen into that hole again in order to finalize the time.

Just do not understand it at all! can you help with model ar-ry7?


An inverter uses 12 volt DC current and inverts it to 110 volt AC current.
Basically, it will take 12 volts from a car battery, and change it to 110 volt current , same as in your house. What part are you having problems with?

Cooler wont cool below 48 degrees.


Keep a thermometer handy. (adjust temperature control knob accordingly)
Periodically monitor temperatures inside your cooler. (adjust as necessary)
Keep the refrigerator door closed as much as possible to avoid temperature fluctuations

The temperature of the refrigerator compartment is
controlled by adjusting/setting the thermostat control
knob, located on the ceiling of the refrigerator
cabinet.
To start the refrigerator, and achieve maximum
cooling quickly;
• Turn the temperature control knob (using a coin
or screwdriver) clockwise to the furthest
(maximum) setting on the darker blue section of
the graduated control dial.
• Allow the refrigerator to run at this setting for 3~4
hours.
• When maximum cooling is achieved, turn back
the temperature control knob setting to the 2:00
o'clock position on the graduated blue control
dial.
• Correct cooling temperature is a key factor to
consider in storing and dispensing draught beer.
• Optimum temperature for serving draught beer is
between 34ºF ~ 38ºF.(1ºC ~ 3ºC)
• To maintain temperatures ranging between
34ºF ~ 38ºF.(1ºC ~ 3ºC) We recommend the
thermostat knob be positioned at the "2:00
o'clock" setting on the graduated blue control dial.
• To turn off the refrigerator, (no cooling) rotate the
control knob to the "0" position.

Low temp conditions


75k ohms resistor is lower than 0 degrees F in equivalent temperature may be compressor cannot operate because the maximum setting of thermostat. is from 17 to 18deg. C. You can use 11 to 12k ohms the temp. for this is about 23 to 24 deg. C. The resistor resistance is fixed so the compressor continue running without cut out. The only problem for this is the compressor, because the design of the compressor is for high temp. Continue running of compressor can produce icing in suction and evaporator coil and cause damage of compressor due to liquid slugging.
