Use & Care - Nova Kool 6200 Series Installation Instructions Manual

7 Use and care
While your Nova Kool unit is quite simple, the following will assist you getting the best
performance of your unit.
• Remove the drip tray at the top of unit. Tests have shown up to a 5 degrees Celsius
higher temperature in your fridge cavity if you leave it in.
• Do not let ice build-up on your evaporator. This can give erratic performance and can
cause the compressor to cut-out when it should be running and visa-versa.
• Check door seals regularly. If you have a faulty door seal, or the door is not sealing
properly, then ice build-up on your evaporator will occur much more quickly.
• Clean your fridge only using warm water with baking soda. DO NOT USE ANY OTHER
CLEANING PRODUCT. It can cause your lining to go brittle or discolour.
• Plan ahead. Turn your unit on several days prior to travelling to let the unit come
down to temperature. The units are not a domestic fridge, where you put kilos of
room temperature food into the fridge to cool it down. Remember the more food
you put in there at ambient temperatures, the more power it will use and the longer
it will take to bring all your warm food down to temperature.
Temperature Control Device - Mechanical thermostat.
The mechanical thermostat is a "contact" type, and you will see it attached to the
evaporator. These are like the original type of temperature controllers used for years in the
first types of fridges.
There is a large dial with a mark, and an indicator point on the body it is mounted in, to
provide a reference to the 7 numbers on the dial.
The numbers reference 1 as being the warmest set point, and 7 being the coldest. If you
wind it around to 0, this will tell the unit to "turn off". Turning it around to 7 will tell the
unit to just keep running.
The position will effectively tell the unit to stop at a certain temperature that the
evaporator will get to, not the air temperature of the cavity. If it is a very hot day, and the
fridge is not keeping things as cool as you would like when compared to a normal
temperature day, turning the thermostat to higher positions will not help. The compressor
will already be running all the time. Once ambient temperatures get over about 38 degrees
Celsius, you can expect this to happen.
The challenge with mechanical thermostats is variables. There are some very expensive
ones available, but they suffer the same issue. There are variances with the position, as to
what temperature you will receive.
Some fridges will run at 1 degree Celsius in the fridge at position 3, while an identical unit
right beside it will require position 4.5 to achieve the same.
