label on the air conditioner saying no excessive charging.
(4) The following tools will be used: 1) Liquid-level gauge; 2) Screwdriver; 3)
Electric driven rotary hammer; 4) Drill; 5) Pipe expander; 6) Torque wrench; 7)
Open-end wrench; 8) Pipe cutter; 9) Leak detector; 10) Vacuum pump; 11)

3.1.2 Selection of Installation Location
WARNING
①. If the outdoor unit will be exposed in strong wind, it must be securely located,
otherwise it may fall down.
②. Install the air conditioner at a place where the inclination is less than 5°.
③. Do not install the unit at a place with direct sunlight.
④. Do not install the unit at a place with leakage of inflammable gas.
Selection of Installation Location for Indoor Unit (Select a location
pursuant to the following condition).
(1) Air inlet and outlet of the indoor unit should be away from obstacles to make
sure the unit’s air flow can reach the entire room. Do not install the unit in a
kitchen or a laundry.
(2) Install the unit in a room without naked flame, fire source or the risk of getting
the refrigerant on fire.
(3) Select a location that can withstand 4 times the unit weight without increasing
operating noise and vibration.
(4) The installation location must be level.
(5) The indoor piping length and wiring length should be within the allowable
range.
(6) Select a place that can easily drain condensate and connect to the drain
system of the air conditioner.
(7) If hoisting screw bolts are to be used, check whether the installation location is
safe enough. If not safe, reinforce the location before installation.
DC Inverter U-match Series Cassette Type Unit
10
(8) Indoor unit, power cord, connecting wires and communication cords should be
at least 1m from television and radio. This is to prevent image interference or
noise (Even at a distance of 1m, a very strong electric wave may still generate
noise).
Selection of Installation Location for Outdoor Unit (Select a location
pursuant to the following condition).
(1) Noise and air flow produced by the outdoor unit will not disturb the neighbors.
(2) Select a location that is safe and away from animals and plants. If not, please
add safety fences to protect the unit.
(3) Install at a place with good ventilation. Make sure the outdoor unit stays at a
well-ventilated place with no obstacles nearby that may obstruct the air inlet
and outlet.
(4) The installation location should be able to withstand the weight and vibration of
outdoor unit and allow the installation to be carried out safely.
(5) Avoid installing at a place with leakage of inflammable gas, oil smoke or
corrosive gas.
(6) Keep it away from strong wind because strong wind will affect the outdoor fan
and lead to insufficient air flow volume and thus affecting the unit’s
performance.
(7) Install the outdoor unit at a place that is convenient for it to be connected to the
indoor unit.
(8) Away from any object that may get the air conditioner generating noise.
(9) Install the outdoor unit at a place where condensate can be easily drained.
3.1.3 Unit Dimension
WARNING
①. Install the indoor unit in a location which can withstand a load of at least five
times the weight of the main unit and which will not amplify sound or vibration.
②. If the installation location is not strong enough, the indoor unit may fall and
cause injuries.
③. If the job is done with the panel frame only, there is a risk that the unit will
come loose. Please take care.

3.2 Unit Installation
3.2.1 Indoor Unit Installation
In order to make the front panel cover 20mm of the ceiling, the distance
between the ceiling and the unit should be 35mm or less. If the distance between
the ceiling and the unit is above 35mm, add some ceiling material to shorten the
distance. See the following diagram.
Ceiling material
≤35mm ≤35mm
3.2.1.1 Hoisting the Main Body Unit
NOTICE
Please tightly screw up the nuts and bolts to prevent the air conditioner from falling.
(1) Installing the Suspension Bolts.
1) Using the installation template, drill holes for bolts (four holes).
2) Install the bolts to the ceiling at a place strong enough to hang the unit.
Mark the bolt positions from the installation template. With a concrete drill,
drill for 12.7 mm (1/2") diameter holes.
3) Insert the anchor bolts into the drilled holes, and drive the pins completely
into the anchor bolts with a hammer.
