„
Do not touch the refrigerant pipes during and immediately after operation.
During and immediately after operation, the refrigerant pipes are may be hot and may be cold,
depending on the condition of the refrigerant flowing through the refrigerant piping, compressor,
and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the
refrigerant pipes.
„
Do not turn off the power immediately after stopping operation.
Always wait at least five minutes before turning off the power.
Otherwise, water leakage and trouble may occur.
„
Do not use a charging cylinder.
Using a charging cylinder may cause the refrigerant to deteriorate.
Note:
„
Install the indoor and outdoor units, power supply wiring and connecting wires at least
3.5ft. away from televisions or radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 3.5ft. may not be sufficient enough to eliminate
the noise.)
„
This unit is a class A product.
In a domestic environment this product may cause radio interference in which case the user
may be required to take adequate measures.
„
Dismantling of the unit, treatment of the refrigerant, oil and eventual other parts, should
be done in accordance with the relevant local and national regulations.
„
Do not use the following tools that are used with conventional refrigerants. (Gauge
manifold, charge hose, gas leak detector, reverse flow check valve, refrigerant charge
base, vacuum gauge, refrigerant recovery equipment.)
If the conventional refrigerant and refrigerator oil are mixed in the R410A, the refrigerant may
deteriorated.
„
Never perform outdoor unit piping connection work when it is raining.
CAUTION The refrigerant R410A requires strict cautions for keeping the system clean, dry and tight.
A.Clean and dry
Foreign materials (including mineral oils such as SUNISO oil or moisture) should be prevented from
getting mixed into the system.
B.Tight
R410A does not contain any chlorine, does not destroy the ozone layer, and does not reduce the
earth's protection against harmful ultraviolet radiation.
R410A can contribute slightly to the greenhouse effect if it is released. Therefore we should take
special attention to check the tightness of the installation.
Read the chapter "Refrigerant piping" carefully and follow these procedures correctly.
CAUTION Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid
state. (If the refrigerant is charged in a state of gas, its composition changes and the system will not
work properly.)
The indoor unit is for R410A. See the catalog for indoor unit models which can be connected.
(Normal operation is not possible when connected to other units.)
