Installation and Operations Manual
Use original accessories and the stated components for the
installation. Install the unit in a location with good support.
Unsuitable installation locations can cause the unit to fall and
cause material damage and personal injury. Installation without
sufficient support can also cause vibrations and noise. Ensure
that the unit is stable when installed, so that it can withstand
earthquakes or strong winds.
The electrical installation must be carried out by a qualified
electrician and the system must be connected as a separate
circuit.
Power supply with insufficient capacity and incorrect function
can cause electrical shocks and fire. Use the wire size sufficient
for the MCA (Minimum Circuit Ampacity) per the electrical data
tables for the electrical connection, tighten the cables securely
in the terminal blocks and support the wiring correctly to
prevent overloading the terminal blocks. Loose connections or
cable mountings can cause abnormal heat production or fire.
Care
Carry out the electrical installation with care. Do not connect
the ground lead to gas lines, water lines, lightning conductors,
or telephone line ground leads. Incorrect grounding can cause
unit faults such as electrical shock due to short-circuiting. Use
disconnect switches with sufficient breaker capacity. Wiring
must be routed to prevent damage by metal edges or trapped by
panels.
Do not install the indoor or outdoor unit near locations where
leakage of combustible gases can occur. Do not install the
unit where corrosive gas or combustible gas or liquids can
accumulate or be handled. The Indoor Module is not waterproof
and must be installed indoors.
Do not install and use the system close to equipment that
generates electromagnetic fields or high frequency harmonics.
Equipment such as inverters, standby generators, medical high
frequency equipment and telecommunications equipment can
affect the unit and cause malfunctions and breakdowns. The
unit can also affect medical equipment and telecommunications
equipment, so that it functions incorrectly or not at all.
Insulate the unit’s connection pipes so that the ambient air
moisture does not condense on them. Insufficient insulation can
cause condensation, which can lead to moisture damage on the
roof, floor, furniture, and valuable personal property.
Follow all Local and Federal safety procedures when handling
or setting of the equipment:
•
Properly dispose of all packaging materials.
•
Touching any control buttons with wet hands can cause
electric shocks.
•
Do not shut down the power supply until at least 5 minutes
of operation to prevent water leakage or breakdowns.
•
Only R-410A refrigerants can be used and charging must be
done in a liquid form.
•
Do not touch any buttons with wet hands. This can cause
electric shocks.
•
Do not touch any refrigerant pipes with your hands when
the system is in operation.
•
During operation, the pipes become extremely hot or
extremely cold, depending on the method of operation. This
can cause burn injuries or frost injuries.
•
Do not shut off the power supply immediately after
operation has started.
•
Do not use other refrigerants than R-410A.
•
When filling refrigerant, the refrigerant must always leave
the container in liquid form.
Do not install the outdoor unit in the following locations:
•
Locations Where potential leakage of combustible gas’ can
occur.
•
Locations where carbon fiber, metal powder or other
powder like substances could enter the air.
•
Locations where chemical substances could affect the
unit (for example, sulfide gas, chlorine, acid, or alkaline
substances can occur).
•
Locations near vented appliances including, driers, HRV’s,
ERV’s, furnaces, boilers, fireplaces, any fossil fuel appliances
or moisture producing equipment.
•
Locations with direct exposure to oil mist or steam.
•
Locations near vehicle exhaust.
•
Locations where machines that generate high frequency
harmonics are used.
•
Locations where cosmetic or special sprays are often used
•
Locations that can be subjected to direct salty atmospheres.
•
Locations where large amounts of snow may accumulate.
A snow stand should be used to elevate the unit above the
typical snow line. A snow hood may be required to protect
the top of the unit.
•
Locations where the system is exposed to chimney smoke.
•
Locations where animals or pets may be fenced in.
Delivery and Handling
Unit must be transported and stored vertically.
Notes:
•
Ensure that the heat pump cannot fall over during transport.
•
Ensure that the heat pump cannot be damaged during
transportation.
⚠
WARNING
⚠
INSTALL THE SYSTEM IN ACCORDANCE WITH THIS
INSTALLATION MANUAL. IMPROPER INSTALLATION
CAN CAUSE LINES TO BURST, PERSONAL INJURY,
WATER LEAKS, REFRIGERANT LEAKS, ELECTRICAL
SHOCK, AND FIRE.
⚠
WARNING
⚠
DISCONNECT THE POWER SUPPLY IN THE EVENT OF
A SERVICE OR INSPECTION. FAILURE TO DISCONNECT
POWER SUPPLY RISKS ELECTRICAL SHOCK AND
DAMAGE DUE TO THE ROTATING FAN. DO NOT RUN
THE UNIT WITH PANELS REMOVED. TOUCHING
ROTATING EQUIPMENT, HOT SURFACES OR HIGH
VOLTAGE PARTS CAN CAUSE PERSONAL INJURY,
BURNS, OR ELECTRICAL SHOCK.
⚠
CAUTION
⚠
IF THE CONDENSATE DRAIN WILL BE CONNECTED
TO PIPING, DO NOT USE A TRAP. IF PIPED, HEAT
TAPE MUST BE INSTALLED TO AVOID FREEZING
AND BURSTING OF THE PIPING. PIPING FROM THE
CONDENSATE DRAIN IS NOT REQUIRED BUT MUST BE
CONSIDERED IF CONDENSATE RUN-OFF WILL CAUSE
DAMAGE TO THE FOUNDATION, LANDSCAPING, OR
OTHER STRUCTURES THAT MAY BE AFFECTED BY
CONDENSATE RUN-OFF.
