[. . . ] . 1. 0 INTRODUCTION IMPORTANT: THIS APPLIANCE IS NOT INTENDED FOR THE USE BY PERSONS (INCLUDING CHILDREN) WITH REDUCED PHYSICAL, SENSORY OR MENTAL CAPABILITIES, OR LACK OF KNOWLEDGE AND EXPERIENCE, UNLESS THEY HAVE BEEN GIVEN SUPERVISION OR INSTRUCTION CONCERNING THE USE OF THE APPLIANCE BY A PERSON RESPONSIBLE FOR THEIR SAFETY. This unit, for use with the air to water heat pump system, is a purpose designed unvented water cylinder. The unit has a stainless steel inner vessel which ensures an excellent standard of corrosion resistance. The outer casing is a combination of resilient thermoplastic mouldings and plastic coated corrosion proofed steel sheet. The unit is supplied complete with all the necessary safety and control devices needed to allow connection to the cold water mains. [. . . ] Refer to the wiring details in the Hydro Unit Installation Manual. The supply cable to the cylinder heater must be routed through the right hand cable gland provided and the outer sheath of the cable firmly secured by tightening the cable gland. Connection must be to the terminal block marked `MAINS'. The recommended cable type is 2. 5mm2 3 core heat resistant sheathed. The thermal sensor connection cable must be routed through the left hand cable gland provided and the outer sheath of the cable firmly secured by tightening the cable gland. Connection must be to the terminal block marked `SENSOR'. The sensor cable should be 0. 75mm2 2 core and shield (ground) with a maximum current rating of 100mA. The cable shielding wire must be connected to the terminal marked on the sensor terminal block. Thermal control of the water cylinder is managed by the Heat Pump controls on the Hydro Unit. Refer to the Hydro Unit Installation Manual for details of how to set up the thermal control. The electrical supply from Hydro Unit to the cylinder heater incorporates an over temperature thermal cut-out that will switch off the heater in the event of a thermal control failure. Remove the Pressure Reducing Valve Cartridge by unscrewing from the housing. Pull the Reducing Valve cartridge from the housing to access the strainer mesh. Wash any particulate matter from the strainer under clean water. Re-assemble ensuring the seal is correctly fitted, DO NOT use any other type of sealant. Ensure the Pressure Reducing Valve Cartridge is fully tightened. 6. 4 DESCALING CYLINDER HEATER Before removing the cylinder heater the unit must be drained. Ensure the water and electrical supply and air to water heat pump are OFF before draining. Attach a hose pipe to the drain cock having sufficient length to take water to a suitable discharge point below the level of the unit. Open a hot tap close to the unit and open drain cock to drain unit. ISOLATE FROM MAINS BEFORE REMOVING TERMINAL COVER. Disconnect the link wires connecting the thermal cut-out to the cylinder heater. [. . . ] 8. 2 TEMPERATURE CONTROL The water storage temperature at the air to water heat pump water heater is set at the control panel of the Hydro Unit. This can be set to give temperatures in the range of 40°C to 75°C, 60°C is recommended. Refer to the Air to Water Owners Manual for details of how to adjust the temperature if necessary. The water cylinder is fitted with an over temperature thermal cut-out that will operate should the thermostatic control fail. [. . . ]
