MULTI SPLIT SYSTEM DCI INSTALLATION INSTRUCTIONS 2009
Getting started... ATTENTION 1. Selection of the units location. Select a location which is rigid and strong enough to support or hold the unit and select a location for easy maintenance. 2. Do not release refrigerant during piping work for installation, reinstallation and during repairing a refrigeration parts. Take care of the liquid refrigerant, it may cause frostbite. 3. Installation work. It may need two people to carry out the installation work. 4.
w’INSTALLATION / SERVICE TOOLING FOR R410A Changes Gauge manifold As the working pressure is high, it is impossible to measure the working pressure using conventional gauges. In order to prevent any other refrigerant from being charged, the port diameters have been changed. Charge hose In order to increase pressure resisting strength, hose materials and port sizes have been changed (to 1/2 UNF 20 threads per inch). When purchasing a charge hose, be sure to confirm the port size.
GENERAL PRECAUTION Always use the support of a large radius cylinder for banding the tubes, using pipe bending tools Tighten electrical circuits cables Tighten electrical circuits cables Do not leave nuts of gas tubes uncovered Avoid pipes bending and keep pipes as short as possible. 5 Do not untie gas tubes after installation Making of install a water trap (Siphon) Do not out of the window will prevent bad odors and assure proper drainage.

PIPES CONNECTION CUTTING AND FLARRING THE PIPES 1. Please use the pipe cutter for cutting the pipes. 2. Remove all burrs by using reamer. Gas leakage might happen If burrs are not removed! Turn pipes edge down to avoid metal powder from entering down the pipes. 3. To cut Surface damaged Uneven thickness Coppet pipe Reamer After inserting the flare nut into the cooper pipes, please make a flare. 0.0-0.5mm Bar Inclined Cracked Coppet pipe PIPE INSULATION 1. 2.
PIPES CONNECTION UNIT A Liquid Flare nut – ¼” I Suction Flare nut – 3/8” I (9.53Imm) UNIT B Liquid Flare nut – ¼” I Suction Flare nut – 3/8” I (9.53Imm) UNIT C Liquid Flare nut – ¼” I Suction Flare nut – 3/8” I (9.53Imm) UNIT D Liquid Flare nut – ¼” I Suction Flare nut – 1/2” I (12.7Imm) UNIT E Liquid Flare nut – ¼” I Suction Flare nut – 1/2” I (12.7Imm) For large indoor units of 5.0(18); 6.0(21); 7.0(24) kW – Always use the lower connection points “Unit D” and “Unit E”.
ELECTRICAL CONNECTIONS 1. Electrical wiring and connections should be made by qualified electricians in accordance with local electrical codes and regulation. The air conditioner units must be grounded. 2. 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. 3. Voltage should not vary beyond ± 10% of the rated voltage. 4.
FEATURES SETUP Display Board general description The display board serves as interface between the installer/technician and the A/C unit. Up Buttons description: Up & Down - used to scroll between options (up and down) Esc Select Select - used to select an option Escape - Will go up one level in the menu Down THERMAL MODE SETTING If an indoor unit is defined as the priority unit, the operational mode (Cool/Heat) will be than defined according to this unit.
Feature set up with dry contacts (Input) The input dry contacts are used for controlling an external circuitry which may include a switch or a relay should be used for closing the internal circuit to indicate that some change is required. A wire of up to 1.5mm2 is recommended to be used.
Open – Alarm Signal Shorted – Normal Operation When “Alarm” dry contact is open, alarm output will be activated when there is any ODU fault or protection. Alarm output will turn off as soon as the fault is cleared. Output specifications: Voltage – Max 24VAC/DC Current – Max 3.0Amp 2 A wire of up to 1.5mm is recommended to be used. ACCESSORIES set up BASE HEATER (BH) Base Heater is a heating element designed to melt any ice that is accumulated on the outdoor unit base during heating operation.
INSTALLATION TEST 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, Cd and Ce has to be connected to the indoor units A, B, C, D and E respectively. To serve this purpose the system is designed to have “installation Test Mode”. When this mode is set, the unit verifies whether the correct connections were made or not. Notes: 1.
b. Entering by scrolling the menu (any time) Mode (CL/Ht/Sb) Enter the test by scrolling down to installation test (It) 1. Press the “Down” button until “It” is shown on the display. Installation Test (It) 2. Press “Select”. 3. Scroll down until the display shows “bgn”. 4. Press “Select”. Esc 1. Scroll Down Diagnostics (diA) 2. Select Up Technician Test (tt) Select Down Set Up (StP) 3.
CHECK LIST BEFORE OPERATION CHECK THE DRAINAGE EVALUATION OF THE PERFORMANCE Pour water into the drain tray-styrofoam. Operate the unit at cooling mode and high fan speed for fifteen Ensure that water flows out from drain hose of the indoor unit. minutes or more Measure the temperature of the intake and discharge air. Ensure the difference between the intake temperature and the discharge is more than 8°C.
