Product code plate affixed to the individual unit reflects the specifications of the individual unit. Page 8 Premier Heat Pumps – Water Heater and Chiller Manual 3 - Installation 3-1 Locating the Unit It is important to install the hot water heat pump in accordance with the following instructions. Water and electrical connections must be carried out by a suitably qualified tradesman or installer • The appliance must be installed outside. • The appliance must be mounted on its anti-vibratory studs, positioned on a substantial platform (concrete or steel pad). The platform must have sufficient height to prevent water entering the bottom of the unit and also allow the condensate to drain freely from the connection at the bottom of the unit • Vegetation and other obstacles must be kept clear of the unit, in accordance with the minimum distances detailed below • The unit should be positioned so that the exhaust does not blow towards windows or doorways. • There must be a minimum clear distance above the unit of 1.5m • The stability bracket on the back of unit must be securely fixed to a post or wall so as to position the unit vertically and prevent any movement of the unit. • Connect the drain pipe to the condensate outlet and direct it away from the unit. Caution • Do not install the appliance in an area where dirt, mud, mown grass or other foreign objects could affect airflow around the unit causing damage or operational issues. • Shelter the unit from prevailing winds • Shelter the unit from falls of snow or heavy rain fall • Prevent children from playing on or around the unit Page 9 Premier Heat Pumps – Water Heater and Chiller Manual 3-2 Water connections Please refer to the diagram below: 1) Connect the hot water in pipe (hot water supply pipe) to the outlet port on the hot water cylinder. Pay attention to heat preservation and ensure appropriate thermal insulation of the pipe work. It is important that the unused hot water outlet port be properly capped. The plastic transport caps are not suitable for this function. 2) Install a water filter (where necessary) and one-way valve in the tap water ( inlet water pipe) and then connect the tap water pipe (inlet water pipe) to the inlet port on the tank. 3) Fill the tank with water. Open the tap water (inlet water) in-valve allowing the tank to fill with water; Meanwhile, open the hot water out-valve, until the water spills over from the hot water out valve. Once this happens the tank is full of water. Close the tap water (inlet water) in-valve, check and ensure that there is no leakage in the system. Re open all valves. Attention: Be sure the tank is full of water before it is switched on. Warning: The inlet and outlet plastic caps are for transport only. Any unused inlet or outlet ports must be blanked off properly using compliant metal pipe caps. Page 10 Premier Heat Pumps – Water Heater and Chiller Manual 3-3 Electrical Connections CAUTION: before connecting the appliance, make sure that the supply power line is disconnected from the network. General Power Supply Characteristics • Neutral mode TT and TN.S; the circuit of the heat pump must be connected to the earth circuit Connections • The electric installation must be carried out by a qualified professional or electrician • The power supply of the heat pump must come from an independent circuit and have the appropriate circuit protection. • The controller must be installed on an indoor wall in an easily accessible area. Electrical Protection • Circuit breaker curves D or standard fuse protection Am, gauged with 16A • Differential protection of 30mA Connection to an Electrical Plug • The heat pump comes packaged with an electric cable and plug. • The plug must be safe, protected from rain and water and the condition checked regularly Before starting the heat pump hot water cylinder, it is important to fully read this manual and understand the operation and the settings. Page 11 Premier Heat Pumps – Water Heater and Chiller Manual 3-4 How the reversible heat pump operates By using the free energy contained in the ambient air, the heat pump enables the heating of the water in a very economical way. Your heat pump is a heat machine that can transfer the heat from a low temperature area (ambient air) to a higher temperature area. How the pump operates in heating mode: The heat of the air is absorbed by the cold, liquid refrigerant, through the evaporator (radiator with wings), the refrigerant is vaporised. Then the compressor increases the pressure and the temperature, and sends it into the condenser (exchanger) where it loses its heat by transferring it to the water. The refrigerant then returns to the liquid state, it loses its pressure and cools again, flowing into the pressure reducer before returning to the evaporator for a new cycle. Operating cooling mode or defrosting mode: A 4 way valve enables a reverse cycle of the refrigerant; this fluid liquid is vaporized in the exchanger (the evaporator) by takin...
