• Install the unit where the ceiling is horizontal and enough to bear the weight of the indoor unit.
• Install the unit where the air inlet and outlet are not baffled and are the least affected by external air.
• Install the unit where the supply airflow can be sent to all parts of the room.
• Install the unit where it is easy to lead out the connective pipe and the drain pipe.
• Install the unit where connotative heat is emitted from a heat source directly.

CAUTION

• Installing the equipment in any of the following places may lead to faults of the equipment (if that is inevitable, consult the supplier):
• The site contains mineral oils such as cutting lubricant.
• Seaside where the air contains much salt.
• Hot spring areas where corrosive gases exist, e.g., sulphide gas.
• Factories where the supply voltage fluctuates seriously. Inside a car or cabin.
• A place like the kitchen where oil permeates.
• A place where strong electromagnetic waves exist.
• A place where flammable gases or materials exist.
• A place where acid or alkali gases evaporate.
• Other special environments.

Precautions before installation

• Decide the correct way of conveying the equipment.
• Try to transport this equipment with the original package.
• If the air conditioner needs to be installed on a metal part of the building, electric insulation must be performed, and the installation must meet the relevant technical standards of electric devices.
• Before installing the unit, be sure to confirm with the user whether there are wires, water pipes, air pipes and so on in the wall or ground of the installation site to avoid accidents due to damage.

Installing the fan coil units
Confirm the dimensions of the indoor unit against the following figure.

• Install Φ10 pendant bolts (4 bolts)
• The intervals of the pendant bolts are shown in the following figure.
• Use the Φ10 pendant bolts.
• The treatment of the ceiling varies between buildings. For detailed measures, negotiate with the construction and fit-out staff.
• Scope of dismantling the ceiling…Please keep the ceiling horizontal. Reinforce the beams and girders of the ceiling lest vibration of the ceiling.
• Cut off the beams and girders of the ceiling.
• Reinforce the cut-off part, beams and girders of the ceiling.
• After the main body is suspended, work on the pipes and wires in the ceiling. Decide the lead-out direction of the pipes after selecting the installation site. Especially, in a circumstance where a ceiling is available, extend the refrigerant pipe, drain pipe, indoor/outdoor connection wires and wire controller lines to the connection position before suspending the unit.

The procedure of installing the pendant bolts.

• Based on the unit structure, please set the screw pitch according to the size of the following figures: Wooden structure

• Put rectangular sticks across the beams, and set pendant bolts.

• Old concrete roughcast
  Use embedded bolts and embedded pulling plugs.

• Steel beam and girder structure
  Set and use supportive angle steel.

• New concrete roughcast
  Set it with embedded bushes or embedded bolts.

Suspending the indoor unit
Use tools such as pulleys to hoist the indoor unit to the pendant bolt.
Use tools such as gradienter to settle the indoor unit horizontally. Lack of horizontality may cause water leak.

Connect the duct
The duct length is determined according to the external static pressure.

Before out from factory, the scupper adopts the pipe thread.

NOTE

• Be sure to perform heat insulation for the drain pipe of the indoor unit. Otherwise, condensate will occur. The joint of the indoor unit should also undergo heat insulation treatment.
• When performing the pipes connection, use the rigid PVC binder, and make sure that no leak exists.
• Same as the joint of the indoor unit. Be careful not to apply force at the pipe side of the indoor unit.
• The downward gradient of the drain pipe should be higher than (1/100), without bend in the middle.
• The total length of the drain pipe when pulled out traversely shall not exceed 20m, when the pipe is over long, a prop stand must be installed prevent winging.
• The centralized pipes should be distributed against the figure shown on the right side.

Drain test

• Before the test, ensure that the drain pipes are smooth and the adapters are sealed.
• Newly built rooms should undergo the drain test before the ceiling is laid.

WIRING

CAUTION

• The air conditioner should use a separate power supply with a rated voltage.
• The external power supply to the air conditioner should have ground wiring, which is linked to the ground wiring of the indoor and outdoor unit.
• The wiring work should be done by qualified persons according to the circuit drawing.
• An all-pole disconnection switch having a contact separation of at least 3mm in all poles should be connected in fixed wiring. The appliance shall be installed by national wiring regulations.
• Be sure to locate the power wiring and the signal wring well to avoid cross-disturbance.
