Before Starting The Test Run; Before Getting Started; Before Getting Installed (Moved)-Electrical Work - Mitsubishi Electric TRANE TPVFYP012AM141 Series Installation Manual

3.3. Before getting started

Caution:
• Do not install the unit where combustible gas may leak.
− If the gas leaks and accumulates around the unit, an
explosion may result.
• Do not use the air conditioner in special environments.
− Oil, steam, sulfuric smoke, etc. can significantly reduce the
performance of the air conditioner or damage its parts
• When installing the unit in a hospital, communication
station, or similar place, provide sufficient protection
against noise.
− The inverter equipment, private power generator, high-
frequency medical equipment, or radio communication
equipment may cause the air conditioner to operate
erroneously, or fail to operate. On the other hand, the air
conditioner may affect such equipment by creating noise
that disturbs medical treatment of image broadcasting.
• Do not install the unit on a structure that may cause
leakage.
− When the room humidity exceeds 80% or when the drain
pipe is clogged, condensation may drip from the indoor
unit. Perform collective drainage work together with the
outdoor unit, as required.
• When the ambient dew point temperature exceeds
75 °F (24 °C), dew condensation may occur on the unit
surface. Perform appropriate treatment to avoid dew
condensation.
3.4. Before getting installed (moved)-electrical
work
Caution:
• Ground the unit.
− Do not connect the ground wire to gas or water pipes,
lightning rods, or telephone ground lines. Improper
grounding may result in electric shock.
• Install the power cable so that tension is not applied to
the cable.
− Tension may cause the cable to break and generate heat
and cause a fire.
• Install a leak circuit breaker as required.
− If a leak circuit breaker is not installed, electric shock may
result.
• Use power line cables of sufficient current carrying
capacity and rating.
− Cables that are too small may leak, generate heat, and
cause a fire.
• Use only a circuit breaker and fuse of the specified
capacity.
− A fuse or circuit breaker of a larger capacity or a steel or
copper wire may result in a general unit failure or fire.
• Do not wash the air conditioner units.
− Washing them may cause an electric shock.
• Be careful that the installation base is not damaged by
long use.
− If the damage is left uncorrected, the unit may fall and
cause personal injury or property damage.

• Install the drain piping according to this Installation
Manual to ensure proper drainage. Wrap thermal
insulation around the pipes to prevent condensation.
−
Improper drain piping may cause water leakage and damage
to furniture and other possessions.
• Be very careful about product transportation.
− If the product weighs more than 20 kg [44 lb], then more than
one person should carry the product.
− Some products use PP bands for packaging. Do not use any
PP bands for a means of transportation; it is dangerous.
.
− Do not touch the heat exchanger fins. Doing so may cut your
fingers.
• Safely dispose of the packing materials.
− Packing materials, such as nails and other metal or wooden
parts, may cause stabs or other injuries.
− Tear apart and throw away plastic packaging bags so
that children will not play with them. If children play with a
plastic bag which was not torn apart, they face the risk of
suffocation.

3.5. Before starting the test run

Caution:
• Turn on the power at least 12 hours before starting
operation.
− Starting operation immediately after turning on the main
power switch can result in severe damage to internal parts.
Keep the power switch turned on during the operational
season.
• Do not touch the switches with wet fingers.
− Touching a switch with wet fingers can cause electric shock.
Do not touch the refrigerant pipes during and immediately
•
after operation.
− During and immediately after operation, the refrigerant pipes
may be hot or 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 operate the air conditioner with the panels and
guards removed.
− Rotating, hot, or high-voltage parts can cause injuries.
• 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.
