Fea tur es eatur tures • Easy Installation - The wall mounted fan coil unit is easily installed because of its compact size, slimness and light weight. - Slim and short outdoor unit can be easily installed even in a narrow balcony and passageway and yet have a stable profile. • Space Saving - No space is required on either floor or ceiling. This newly developed super slim design for wall mounting maximizes floor space usage and enhances ceiling appearance where ceilings are low.

Saf ety Pr ecaution Bef or e Installa tion Safety Precaution Befor ore Installation Before operating, please read the following “Safety Precautions” carefully. To prevent injury to the user or other people and properties damage, the following instructions must be followed. ! Incorrect operation due to ignoring of instruction will cause harm or damage, the seriousness is classified by the following indications. Warning: This sign indicates the possibility of causing death or serious injury.
Symbol (with white background) denotes item that is PROHIBITED from doing. Symbol (with black background) denotes item that is COMPULSORY to be carried out. ! Caution Please confirm the following important points when installation • Grounding is necessary It may cause electrical shock if grounding is not perfect. • Do not install the unit where leakage of flammable gas may occur In case of gas leaks and accumulates at the surrounding of the unit, it may cause fire ignition.
Special Pr ecautions F or R407C Precautions For Special Precautions When Dealing With Refrigerant R407C Unit 1) What is new refrigerant R407C? R407C is a zeotropic refrigerant mixture which has Zero Ozone Depletion Potential (ODP = 0) and thus conformed to the Montreal Protocol regulation. It requires Polyol-ester oil (POE) oil for its compressor’s lubricant. Its refrigerant capacity and performance are about the same as the refrigerant R22.
b) Ensure that the compressor is not expose to open air for more than the recommended time specified by its manufacturer (typically less than 10 minutes). Removed the seal-plugs only when the compressor is about to be brazed. c) The system should be thoroughly vacuumed to 1.0 Pa (-700mmHg) or lower. This vacuuming level is more stringent than R22 system so as to ensure no incompressible gas and moisture in the system.
Installa tion Installation Installation Diagram 72
CAUTION: Before installing the unit, ensure that the power supply matches the power requirement of the air conditioner. 1) Selection Of Location And Space (A) INDOOR UNIT Install the fan coil (indoor) unit at a location with the following requirements · Location is suitable for wiring, piping and drainage. · No obstruction of air flow into and out of unit where cooler air can be evenly distributed.(See fig. 1) · Ensure that air discharge is not short circuited with air intake.
(B) Outdoor Unit As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve maximum cooling capacity, the location selected for outdoor unit should fulfill the following requirements : • Install the condensing (outdoor) unit in away such that hot air distributed by the outdoor condensing unit cannot be drawn in again (as in the case of short circuit of hot discharge air). Allow sufficient space for maintenance around the unit.
Condensed Water Disposal Of Outdoor Unit (Heatpmp Unit Only) • There are 2 holes on the base of outdoor unit for condensed water to flow out. Insert the drain elbow to one of the holes. • To install the drain elbow, first insert one portion of the hook to the base (portion A), then pull the drain elbow in the direction shown by the arrow while inserting the other portion to the base. After installation, check to ensure that the drain elbow clings to base firmly.
2) Drillings Holes And Mounting Installation Plate CAUTION: i) Please check the unit weight for each model. Always ensure that the wall is sufficiently strong to withstand the weight. If not, it is necessary to reinforce the wall with plate, beams or pillars. ii) The unit cannot be directly fixed onto the wall or the likes. In all cases, the installation plate provided MUST be used. • Paste the installation plan provided on the desired location on the wall and mark the holes location accordingly.
3) Indoor Unit Preparation • The refrigerant piping can be routed to the unit in 5 direction, by using the cut outs in the unit casing. (See fig. 1) • Carefully bend the pipes to the required position to align with the hole. For right hand and rear side draw out, hold the bottom of the piping and fix direction before shaping it to the desired position (See fig. 2). The condensation drain hose should be taped to the pipes with vinyl tape. The electrical cable can also be taped to the pipes.
5) Water Drainage Piping The indoor drain pipe must be downward gradient for smooth drainage. Avoid situation as shown in figure below. 6) Wiring Electrical Connection • Wiring regulation on wire diameters differ from country to country. Please refer to your LOCAL ELECTRICAL CODES for field wiring rules. Be sure that installation comply with such rules and regulations.
7) Installation Of Separate Orifice Kit At Outdoor i) Outdoor Unit Installation Space Is Wide Enough STEP 2 ORIFICE PIPE STEP 1 Steps: a) Directly connect the “Female” nut of orifice pipe to the liquid pipe. b) Flare the liquid pipe and connect it to the “Male” joint of the orifice pipe.
ii) Outdoor Installation Space Is Limited Step 4 Orifice Pipe Step 3 Step 2 If the orifice pipe cannot be connected directly to the liquid valve due to limitation space, it can be connected between the liquid pipes. Step 1 Steps : a) Flare the liquid pipe and connect it to the liquid valve. b) Braze an addition “Male” joint to the liquid pipe. Liquid Pipe Buzzer c) Connect the “Female” nut of the orifice pipe to the “Male” joint.
8) Refrigerant Piping Maximum Pipe Length And Maximum Number Of Bends Always choose the shortest path for refrigerant piping and follow the recommendations as tabulated below: MODEL DATA Max. Length (m) Max. Elevation (m) Max.

LED Indicator Lights The table below shows the LED indicator light for air conditioner unit under normal operation and fault condition. The LED indicator lights are located at the right bottom of the air conditioner unit.
Heatpump unit : LED Indicator Lights Display Cooling mode (Green) Dry mode (Orange) Sleep mode (Red) Heat / Fan mode (Red/ Green) The heat pump units is equipped with an “auto” mode, whereby the unit will provide reasonable room temperature by switching the unit automatically to either “cool” mode or “heat” mode, according to the temperature setting set by the user.
Special Function (A) 3 Hot System (Heating cycle) a) Hot start At the beginning of heating operation (cold start, after defrosting or thermostat resumes operation) the indoor fan operation is controlled in accordance with the temperature of the indoor heat exchanger to send warm air from the start. b) Hot keep After thermostat cut out, the indoor fan operation is controlled in accordance with the indoor heat exchanger temperature to utilize the extra heat and preserve indoor comfort.
c) Hot spurt During cold start, the set temperature of controller is increased by 2°C to stabilize the room temperature quickly. After the first stop of compressor or 30 minutes following the start of operation, the temperature setting will be restored to the original value. (B) Cold Blast (Cooling cycle) During cold start, the set temperature of controller is decreased by 20°C to stabilize the room temperature quickly.
(D) Overload Protection In Cooling Operation When outdoor and indoor air temperature raise beyond the operation limit, or when the outdoor coil choked with dirt, the M.C. controller detects abnormal increase in condensing temperature. It will stop the operation to prevent compressor burn out. (E) Frost Prevention And Filter Check In order to prevent the freezing of indoor coil, the controller will operate as follow.
Ser vicing And Maintenance Servicing CAUTION: After installing or servicing the unit, please ensure that the front panel is secured by the 1 hook underneath the front panel. The unit is designed to give a long life operation with minimum maintenance required. However, it should be regularly checked and the following items should be given due attention. Components Maintenance Procedure Recommended Schedule Air filter 1.
Pre-Start Up Maintenance (After Extended Shutdown) - Inspect thoroughly and clean indoor and outdoor units. Clean or replace air filters. Clean condensate drain line. Clean clogged indoor and outdoor coils. Check fan imbalance before operation. Tighten all wiring connections and panels. Check for refrigerant leakage. The design of the MLC outdoor series allows servicing to be carried out readily and easily. The removal of the top side, front and back panel make almost every part accessible.
