Ultra Heat GMV VRF Technical Service Manual PREFACE AND SAFTY PRECAUTIONS
5
Inadequate connection and fastening may generate heat and cause a fire.
Be sure the installation area does not deteriorate with age.
If the base collapses, the air conditioner could fall with it, causing property damage, product failure, or
personal injury.
Install and insulate the drain hose to ensure that water is drained away properly based on the
installation manual.
A bad connection may cause water leakage.
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 may not play with them. If children
play with a plastic bag which was not torn apart, they face the risk of suffocation.
Turn on the power at least 8 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.
Be very careful about product transportation.
Only one person should not carry the product if it weighs more than 44lbs (20kg).
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.
When transporting the outdoor unit, suspend it at the specified positions on the unit base. Also support
the outdoor unit at four points so that it cannot slip sideways.
Do not touch any of the refrigerant piping during and after operation.
It can cause a burn or frostbite.
Do not operate the air conditioner with the panels or guards removed.
Rotating, hot, or high-voltage parts can cause injuries.
Do not directly turn off the main power switch after stopping operation.
Wait at least 5 minutes before turning off the main power switch. Otherwise it may result in water
leakage or other problems.
Auto-addressing should be done in condition of connecting the power of all indoor and outdoor
units. Auto-addressing should also be done in case of changing the indoor unit PCB. Use a firm
stool or ladder when cleaning or maintaining the air conditioner.
Be careful and avoid personal injury.
Do not insert hands or other objects through the air inlet or outlet while the air conditioner is
plugged in.
There are sharp and moving parts that could cause personal injury.
