Mitsubishi Electric CAHV-P500YA-HPB Instruction Manual page 3

Always replace a fuse with one with the
correct current rating.
The use of improperly rated fuses or a
substitution of fuses with steel or copper wire
may result in fire or explosion.
If any abnormality (e.g., burning smell) is
noticed, stop the operation, turn off the
power switch, and consult your dealer.
Continuing the operation may result in electric
shock, malfunctions, or fire.
CAUTION
To reduce the risk of fire or explosion, do not
place flammable materials or use flammable
sprays around the unit.
Do not operate the unit without panels and
safety guards properly installed.
To reduce the risk of injury, do not sit, stand,
or place objects on the unit.
The model of heat pump unit described in this
manual is not intended for use to preserve
food, animals, plants, precision instruments, or
art work.
Do not connect the makeup water pipe
directly to the potable water pipe. Use a
cistern tank between them.
Connecting these pipes directly may cause the
water in the unit to migrate into the potable
water and cause health problems.
To reduce the risk of adverse effects on plants
and animals, do not place them where they
are directly exposed to discharge air from the
unit.
Do not install the unit on or over things
that are vulnerable to water damage.
Condensation may drip from the unit.
To reduce the risk of injury, do not touch the
heat exchanger fins or sharp edges of
components with bare hands.
Properly install all required covers and
panels on the terminal box and control box
to keep moisture and dust out.
Dust accumulation and water may result in
electric shock, smoke, or fire.
Consult an authorized agency for the
proper disposal of the unit.
Refrigerant oil and refrigerant that may be left
in the unit pose a risk of fire, explosion, or
environmental pollution.
Do not release refrigerant into the
atmosphere. Collect and reuse the
refrigerant, or have it properly disposed of
by an authorized agency.
Refrigerant poses environmental hazards if
released into the air.
Do not place a container filled with water
on the unit.
If water spills on the unit, it may result in
shorting, current leakage, electric shock,
malfunction, smoke, or fire.
Always wear protective gears when
touching electrical components on the
unit.
Several minutes after the power is switched
off, residual voltage may still cause electric
shock.
To reduce the risk of injury, do not insert
fingers or foreign objects into air inlet/outlet
grills. If the unit is left on a damaged base, it
may fall and cause injury.
To reduce the risk of injury, wear protective
gear when working on the unit.
In areas where temperature drops to freezing,
use an anti-freeze circuit and leave the main
power turned on to prevent the water in the
water circuit from freezing and damaging the
unit or causing water leakage and resultant
damage to the furnishings.
