Do not touch the heat exchanger fins.
These fins are sharp and could result in cutting injuries.
Do not place items which might be damaged by moisture
under the indoor unit.
Condensation may form if the humidity is above 80%, the
drain outlet is blocked or the filter is polluted.
After a long use, check the unit stand and fitting for
damage.
If damaged, the unit may fall and result in injury.
To avoid oxygen deficiency, ventilate the room
sufficiently if equipment with burner is used together
with the heat pump.
Arrange the drain hose to ensure smooth drainage.
Incomplete drainage may cause wetting of the building,
furniture etc.
Never touch the internal parts of the controller.
Do not remove the front panel. Some parts inside are
dangerous to touch, and a machine trouble may happen.
The function of text run circulate as fowlling.
Never expose little children, plants or animals directly to
the air flow.
Adverse influence to little children, animals and plants may
result.
Do not allow a child to mount on the outdoor unit or
avoid placing any object on it.
Falling or tumbling may result in injury.
Do not operate the heat pump when using a room
fumigation - type insecticide.
Failure to observe could cause the chemicals to become
deposited in the unit, which could endanger the health of
those who are hypersensitive to chemicals.
Do not place appliances which produce open fire in
places exposed to the air flow from the unit or under the
indoor unit.
It may cause incomplete combuston or deformation of the unit
due to the heat.
Do not install the heat pump at any place where
flammable gas may leak out.
If the gas leaks out and stays around the heat pump, a fire
may break out.
The appliance is not intended for use by young children
or infirm persons without supervision.
Young children should be supervised to ensure that they
do not play with the appliance
.
The outdoor unit window-shades should be periodic
cleaning in case of being jammed.
This window-shapes is heat dissipation outlet of components,
if being jammed will cause the components shorten their
service life spans because of overheated for a long time.
The temperature of refrigerant circuit will be high, please
keep the interconnection cable away from the copper
tube.
2. PARTS NAMES
