I N S TA L L AT I O N I N S T R U C T I O N S FOR DCI SPLIT WALL MOUNTED AIR CONDITIONER 1 LOCATION OF OUTDOOR UNIT Select the location considering the following: OUTDOOR UNIT 1. The location must allow easy servicing and provide good air circulation as shown in fig 4. 2. The unit may be suspended from a wall by a bracket (Optional) or located in a free standing position on the floor (preferably slightly elevated). 3.

2 ELECTRICAL CONNECTION BETWEEN OUTDOOR AND INDOOR UNIT ELECTRICAL REQUIREMENTS Electrical wiring and connections should be made by qualified electricians and in accordance with local electrical codes and regulation. The air conditioner units must be grounded. The air conditioner units must be connected to an adequate power outlet from a separate branch circuit protected by a time delay circuit breaker, as specified on unit's nameplate. Voltage should not vary beyond 10% of the rated voltage.
3 INSTALLATION/SERVICE TOOLS (ONLY FOR R410A PRODUCT) CAUTION New Refrigerant Air Conditioner Installation THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE LAYER. R410A refrigerant is apt to be affected by impurities such as water, oxidizing membrane, and oils because the working pressure of R410A refrigerant is approx. 1.6 times of refrigerant R22. Accompanied with the adoption of the new refrigerant, the refrigeration machine oil has also been changed.
4 REFRIGERANT TUBING Tightening torques of unions and valve caps: CONNECT THE INDOOR TO THE OUTDOOR UNIT The indoor unit contains a small quantity of nitrogen. Do not unscrew the nuts from the unit until you are ready to connect the tubing. The outdoor unit is supplied with sufficient refrigerant charge (R410A). Refer to outdoor unit nameplate. Fig 9 NOTE: Use refrigeration R410A type copper tubing only. 2. Use tubing diameter that corresponds to the tubing diameter of the indoor and outdoor units.
5 FEATURES SETUP Display Board 5.1. Display Board general description The display board serves as interface between the installer/technician to the A/C unit. -Scroll ( "Up" & "Down" ) - used to scroll between options (up and down) Up Esc Select -Select - used to select an option. Down -Escape ( "Esc" ) - Will go up one level in the menu Ribbon Connector 5.2.
5.2.2. Forced mode operation If an IDU is defined as a priority unit, the operational mode (Cool/Heat) will be defined according to the priority unit request. If no unit is selected (as the default value) the first unit turned on determines the unit mode. Setup the Forced Mode dry contact to the required mode as per the following: Open-Cool Shorted-Heat Cool open Heat - shorted When "Forced Mode" dry contact is shorted, the unit will be forced to heat mode. 5.3.
5.3.3. Power Shedding Open-Normal operation Shorted Power Shedding When "Power Shedding" dry contact is shorted, the unit will limit its maximum power consumption. 5.4. Features (Output) 5.4.1. Alarm The Alarm ('Output') Dry contact is used to indicate a problem or any malfunction of the system. An internal relay is used to close an external circuit which may include an external power supply. The external circuit should include some kind of a load (lightening bulb, LED, etc.).
6 INSTALLATION TEST MISWIRING CHECK For proper system operation, each communication cable has to be connected to the corresponding indoor unit, following the refrigerant tubes. This means that the communication lines Ca, Cb, Cc, and Cd has to be connected to the indoor units A, B, C, and D respectively. To serve this purpose the system is designed to have the "Installation Test Mode". When this mode is set, the unit verifies whether the correct connections were made or not. Notes: O 1.
7 FINAL TASKS 1. Check all valve caps and ensure that they had tightened properly. Close the valve cover. 2. Fill gaps on the wall between hole sides and tubing with sealer. 3. Attach wiring and tubing to the wall with clamps where necessary. 4. Operate the unit for no less than 5 minutes at heating or cooling mode. 5. Explain filter removal, cleaning and installation. 6. Operate the air conditioner together with the customer and explain all functions. 7.
