SAFETY CONSIDERATIONS
Installing, starting up, and servicing air- conditioning equipment can be hazardous due to system pressures, electrical components, and equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics should install, start-up, and service this equipment.
Untrained personnel can perform basic maintenance functions such as cleaning coils. All other operations should be performed by trained service personnel.
When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment.
Follow all safety codes. Wear safety glasses and work gloves. Keep quenching cloth and fire extinguisher nearby when brazing. Use care in handling, rigging, and setting bulky equipment.
Read these instructions thoroughly and follow all warnings or cautions included in literature and attached to the unit. Consult local building codes and current editions of the National Electrical Code ( NEC ) NFPA 70. In Canada, refer to current editions of the Canadian electrical code CSA 22.1.
!
Recognize safety information. This is the safety- alert symbol When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury. Understand these signal words: DANGER, WARNING, and CAUTION. These words are used with the safety- alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Before installing, modifying, or servicing system, main electrical disconnect switch must be in the OFF position. There may be more than 1 disconnect switch. Lock out and tag switch with a suitable warning label.
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
Do not bury more than 36 in. (914 mm) of refrigerant pipe in the ground. If any section of pipe is buried, there must be
.
a 6 in. (152 mm) vertical rise to the valve connections on the outdoor units. If more than the recommended length is buried, refrigerant may migrate to the cooler buried section during extended periods of system shutdown. This causes refrigerant slugging and could possibly damage the compressor at start- up.
WARNING
CAUTION
GENERAL
These instructions cover the inst allati on, start-up and servic i ng of the multi-zone outdoor unit connec t ed to up to nine indoor fan coil units . For approved combinations, please refer to the Product Data.

HIGH- WALL INDOOR UNIT INSTALLATION
INSTALL MOUNTING PLATE
For each fan coil:
1. Carefully remove the mounting plate, which is attached to the back of the indoor unit.
2. The mounting plate should be located horizontally and level on the wall.
3. If the wall is block, brick, concrete or similar material, drill .2” (5 mm) diamete r holes and insert anchors for t he appropriat e mounting screws.
4. Attach the mounting plate to the wall (see Fig. 2 and 3).
FOR EACH F AN COIL, DRILL HOLE IN WALL FOR INTERCONNECTING PIPING, DRAIN AND WIRING
Refrigerant Line Routing
The refrigerant lines may be routed in any of the four directions showninFig.24(a)and(b).
For maximum serviceability, it is recommended to have refrigerant line flare connections and the drain connection on the outside of the wall that the fan coil is mounted on.
If piping is going through the back:
1. Determine pipe hole position using the mounting plate as a template. Drill pipe hole diameter per chart below. The outside pipe hole is 1/2- in. (13 mm) min. lower than inside pipe hole, so it slants slightly downward (see Fig. 25). If piping is going to exit from the left rear, it is recommended to field-fabricate piping extensions to get the flare connections to the outside of the wall.

CAUTION
S Prior to the inst allation, make a good preparation for all piping
(refrigerant pipe, drain pipe) and wiring (wires of the wired controller, wires between the indoor and outdoor unit) of the indoor unit to make the further installation much easi er.
S If there is an opening in the ceiling, its better to reinforce it
to keep it flat and prevent it from vibrating. Consult the user and builder for more details.
S If the strength of the ceiling is not strong enough, a bea m
made of angle iron can be used and then sec ur e the unit on it.
S If the indoor unit is not installed in the air conditioning
area, please use sponge around the unit to prevent condensing. The thickness of the sponge depends on the actual installation environment.
HORIZONTAL CHECK OF THE INDOOR DUCTED UNIT

CAUTION
S The max. lengt h of the duct means the max. length of the air
supply duct plus the max. length of the ret urn air duct.
S The duct is either rectangular or round and connected with
the air inlet/outlet of the indoor unit. Among all air supply outlets, at least one should remain open. As for the round duct, it needs a transition duct of which the size should match with the air supply of the unit. After the fitting of the transition duct, it is best to keep the round duct 32ft (10m) away from the corresponding diffuser.

INSTALLATION OF THE CONDENSATE PIPE
1. The condensate pipe should keep a inclination angle of 5 ~ 10”, to facilitate the drainage of the condensate water. And the joints of the condensate pipe should be insulated by the insulation material to prevent condensing (see Fig. 36).
Insulating Layer for the Condensate Pipe
5. Insert the drain hose into the drain hole and tighten it with clamps.
6. Wrap the clamps with large amount of sponge for thermal insulation.
7. The drain hose inside the room also should be insulated.
Clamp (accessory)
Sponge (accessory)
Clamp (accessory)
Pipe Lid
Fig. 36 - Thermal Insulation of the Condensate Pipe
2. There is a condens ate outlet on both the left and right sides of the unit. Once one i s confirmed for use, the other should be clogged by a rubber plug, bundle d by the binding wire and insulated by the insulation material to avoid water leakage.
3. The right outlet is defaulted to be clogged with a plug.
IMPORTANT: No water leakage is allowed on the joint of the condensate pipe.
DESIGN OF THE DRAIN PIPE
1. The drain pipe should always be kept an inclination angle (1/50~1/100) to avoid water from gathering.
2. During the connection of the drain pipe and devi ce, do not impose excessive forc e on the pipe on one side of the device. Additionally the pipe should be secured closely to the device.
3. The drain pipe can be the ordinary hard PVC pipe which can be purchased locally. During the connection, inset the end of the PVC pipe to the drain outlet, then tighten it with the drain hose and binding wire. Never connect the drain outlet and the drain hose with adhesive.
4. When the drain pipe is used for multiple devices, the public section of the pipe should be 4 in (100 mm) lower than the drain hole of each device and it is better to use the much thicker pipe for such a purpose.
INSTALLATION OF THE DRAIN PIPE
1. The diameter of the drain pipe should be larger than or equal to that of the refrigerant pipe (PVC pipe, outer
dimater: 1 in (25 mm), wall thickness
2. The drain pipe should be a short as possible and with at least a 1/100 degree of slope to avoid forming air pockets.
3. If the proper degree of slope of the drain pipe is not allowed, a lift pipe should be installed.
4. A distance of 3.28 ft~4.92 ft (1m~1.5 m) should be kept betwe en the hangers to avoid the drain hose from making a turn.
0.06 in (1.5 mm).

PRECAUTIONS FOR THE LIFT PIPE
The lift pipe install height should be less than 33 1/2 in (850 mm). We recommend setting an inclination angle 1~ 2
the drainage direction. If the lift pipe and the unit form a right angle, the height of the lift pipe must be less than 31 1/2 in (800 mm).

Piping Connections to Outdoor
Unit
IMPORTANT: Use refrigeration grade tubing ONLY. No other type of tubing may be used. Use of other types of tubing will void manufacturer’s warranty. Make sure there is enough piping to cover the required length between the outdoor and indoor unit. Only use piping suitable for high side pressure for both high side and low side connections.
Piping Guide:
S Do not open service valves or remove protective caps from
tubing ends until all the connections are made.
S Bend tubing with bending tools to avoid kinks and flat spots. S Keep the tubing free of dirt, sand, moisture, and other
contaminants to avoid damaging the refrigerant system.
S Avoid sags in the suction line to prevent the formation of oil traps.
Insulate each tube with minimum 3/8- in. (10 mm) wall thermal pipe insul ation. Inserting the tubing into the insulation before making the connections will save time and improve installation quality.
1. The unit is equipped with multiple pairs of service valves (Except sizes 48 and 56). Each pair is clearly marked (color and letter) to ide nt ify the indoor unit cir cuits. In the outdoor unit wiring area, each indoor unit interconnecting termina l block is marked (letter) the sam e as the corresponding pair of service valves. The indoor units must be piped and wired in matched sets (A to A; B to B, etc).
2. It is not required to use all of the available fan coil connections if the application does not require them at the current time. The system can be expanded at any time.
3. Conversion joints are supplied with the outdoor unit. They are required for certain fan coil combinations. These joints are to be connected to the outdoor unit as needed to match the line set size.
4. Cut tubing with tubing cutter.
5. Install correct size flare nut onto tubing and make flare connection.
6. Apply a small amount of refrigerant oil to the flare connection on the tubing.
7. Properly align tubing in with service valve (conversion joint).
8. Tighten flare nut and finish installation using two wrenches as shown in Fig. 72.
