Choose a place solid enough to bear the weight and vibration of the unit, where the operation noise will not be amplified. 2. Choose a location where the hot air discharged from the unit, or the operation noise will not cause a nuisance to the neighbours of the user. 3. Avoid places near a bedroom and the like, so that the operation noise will cause no trouble. 4. There must be sufficient space for carrying the unit into and out of the site. 5. There must be sufficient space for air passage and no obstructions around the air inlet and the air outlet. 6. Locate the unit so that the noise and the discharged hot air will not annoy others. 7. The site must be free from the possibility of flammable gas leakage in a nearby place. 8. Install units, power cords and inter-unit cables at least 3m away from television and radio sets. This is to prevent interference to images and sounds. 9. Depending on radio wave conditions, electromagnetic interference can still occur even if installed more that 3m away. 10. In coastal areas or other places with salty atmosphere of sulphate gas, corrosion may shorten the life of the outdoor unit. 11. Since drain flows out of the outdoor unit, do not place anything under the unit which must be kept away from moisture. Selecting a location in cold climates WHEN OPERATING THE OUTDOOR UNIT IN A LOW OUTDOOR AMBIENT TEMPERATURE, BE SURE TO FOLLOW THE INSTRUCTIONS DESCRIBED BELOW. To prevent exposure to wind, install the outdoor unit with its suction side facing the wall. Never install the outdoor unit at a site where the suction side may be exposed directly to wind. To prevent exposure to wind, install a baffle plate on the air discharge side of the outdoor unit. In heavy snowfall areas it is very important to select an installation site where the snow will not affect the unit. If lateral snowfall is possible, make sure that the heat exchanger coil is not affected by the snow (if necessary, construct a lateral canopy). 13 Installation space Mounting the unit When installing the outdoor unit, please refer to "MCS Installation guidelines" to select an appropriate location. 1. Check the strength and level of the installation ground so that the unit will not cause any operating vibration or noise after installation. 2. Prepare 4 sets of M8 foundation bolts, nuts, and washers each. 3. Fix the unit securely by means of the foundation bolts in accordance with the foundation drawing. It is best to screw in the foundation bolts until their length remains 20mm above the foundation surface. 14 Water pipework Checking the water circuit The water circuits must be installed by a licensed technician and must comply with all current regulations. THE UNIT IS ONLY TO BE USED IN A CLOSED WATER SYSTEM. APPLICATION IN AN OPEN WATER CIRCUIT CAN LEAD TO EXCESSIVE CORROSION OF THE WATER PIPING. Before continuing the installation of the unit, check the following points: The maximum water pressure is 6 bar. Two isolation valves (not supplied) must be fitted to facilitate service and maintenance, please install one at each water inlet/outlet. Orientation of the integrated drain and fill valves is important for servicing. Drain taps must be provided at all low points of the system to permit complete drainage of the circuit during maintenance. Air vents must be provided at all high points of the system. The vents should be located at points which are easily accessible for servicing. Do the air purge during the installation. Take care that the components installed in the field piping can withstand the water pressure. Connecting the water circuit Water connections must be made in accordance with the diagram delivered with the unit, respecting the water inlet and outlet connections. BE CAREFUL NOT TO DEFORM THE UNIT PIPING BY USING EXCESSIVE FORCE WHEN CONNECTING THE PIPING. DEFORMATION OF THE PIPING CAN CAUSE THE UNIT TO MALFUNCTION. If air, moisture, or dust gets in the water circuit, problems may occur. Therefore, always consider the following when connecting the water circuit: Use clean pipes only. Hold the pipe end downwards when removing burrs. Cover the pipe end when inserting it through a wall so that no dust and dirt can enter. Use a good thread sealant for the sealing of the connections. The sealing must be able to withstand the pressures and temperatures of the system. When using non-brass metallic piping, make sure to insulate both materials from each other to prevent galvanic corrosion. Because brass is a soft material, use appropriate tooling for connecting the water circuit. Inappropriate tooling will cause damage to the pipes. THE UNIT IS ONLY TO BE USED IN A CLOSED WATER SYSTEM. APPLICATION IN AN OPEN WATER CIRCUIT CAN LEAD TO EXCESSIVE CORROSION OF THE WATER PIPING. NEVER USE ZN-COATED PARTS IN THE WATER CIRCUIT. EXCESSIVE CORROSION OF THESE PARTS MAY OCCUR AS COPPER PIPING IS USED IN THE INTERNAL WATER CIRCUIT OF THE UNIT. WHEN USING A 3-WAY VALVE OR A 2-WAY VALVE IN THE WATER CIRCUIT. THE RECOMMENDED MAXIMUM CHANGEOVER TIME OF THE VALVE SHOULD BE LESS THAN 60 SECONDS. 15 Charging water 1. Connect the water supply to a drain and fill valve. NOTE Water quality must be according to EN directive 98/83 EC. Piping insulation The complete water circuit, inclusive of all piping, must be insulated to prevent and reduction of the heating capacity. Field wiring WARNING A main switch or other means for disconnection, having a contact separation in all poles, must be incorporated in the fixed wiring in accordance with relevant local and national legislation. Switch `off' the power supply before making any connections. All field wiring and components must be installed by a qualified electrician and must comply with relevant European and national regulations. The field wiring must be carried out in accordance with the wiring diagram supplied with the unit and the instructions given below. Be sure to use a dedicated power supply. Never use a power supply shared by another appliance. Be sure to establish an earth. Do not earth the unit to a utility pipe, surge absorber, or telephone earth. Incomplete earth may cause electrical shock. Be sure to install an earth leakage protector. Failure to do so may cause electrical shock. Auxiliary switching Terminal 7 on the PCB via a contactor (not supplied) has the ability to switch an auxiliary electric heater. Use setting L5 from the Parameters list (Page 10) to specify at what ambient air temperature the electric heater operates, adjustable between 0 - 35 16 Pre-operation checks Checks before initial start-up SWITCH OFF THE POWER SUPPLY BEFORE MAKING ANY CONNECTIONS. After the installation of the unit, check the following before switching on the circuit breaker: 1.
