Safety Precautions - Trane CXAJ series Installation, Operation And Maintenance Manual

Safety Precautions

In order to avoid electrical shock or fire, and other
injuries that may be caused, the following rules should
be kept in mind and strictly adhered to:
• The unit power supply and the electric heating power
supply must be equipped with an electric leakage
protection device, and must be connected to the
grounding wire; otherwise, injury or even death and
other accidents may occur if unprotected.
• The specification of the power wire shall meet the
requirements, otherwise there may be accidents
related to circuit safety.
• Please use a fuse appropriate for the current intensity.
• Do not use any temporary substitute, such as a piece
of wire, which not only may damage the unit itself,
but also may cause fire.
Ok!
• In order not to exceed the capacity of the power
meter and the protector, please do not simultaneously
switch on the electric heating for the air conditioner
and the electric heating for the water tank. The use of
all types of electrical appliances shall be coordinated.
• Please connect the wires in strict accordance with the
wiring diagrams in this manual. Improper wiring or
artificial change of wiring will result in unit failure and
damage, or endanger personal safety.
• The condensate water from the indoor and outdoor
units must be drained according to the requirements.
Improper drainage of the condensate water may lead
to adverse consequences.

Using a piece of wire
may cause fire.
• Never sit on the direct air duct at any time. Sitting on
the direct air duct is not conducive to your health and
safety.
• In order to prevent the relief valve failure due to
calcification, fouling and blockage, the user should
check the valve at least once every month. If the local
water quality is poor, the check interval should be
shortened appropriately. Please promptly replace
the relief valve with a new valve with reliable quality
if blockage, corrosion, manual operation failure or
damage to manual pressure relief handle is found.
• A heating device or other heat source shall not
be arranged under or near the air conditioner. The
machine body may be deformed by heating.
• Objects, such as sticks, sands or gravels, shall be
avoided from entering the air inlet grid or air outlet
grid. Fans running at high speed are very dangerous,
and children should be kept away from them.
• Never block or cover the air inlet grid or air outlet
grid. If such case happens, it may reduce the
performance and affect the normal operation
capacity.
• Whenever you operate the machine, make sure the
air filter net is installed correctly. Otherwise, dirt
may enter the internal running position and cause
damage.
• When cleaning the machine, do not sprinkle water
directly on the machine, which may lead to electric
shock.
• Before maintenance, make sure the unit is powered
off to prevent electric shock.
• When the unit is not used for a long period, you
should cut off the power supply and drain the water
from the water tank. After the water is drained, do
remember to close the drain valve. If the water tank
is under frozen conditions for a long time, it may be
damaged.
