Page 11: Temperature Sensor
4.1.3 Temperature sensor Temperature sensor measures the water temperature in the hot water tank to control the entire system. 4.1.4 Corrosion protection In addition, the top part shell of the hot water heater is corrosion resistant (it is made of stainless steel) and the hot water tank is enamelled and also contains magnesium anode which needs to be checked regularly, as recommended by the installer or service technician. -
Page 12: Location
4.2 LOCATION When placing the appliance to the installation site, keep in mind possible future service calls. To avoid having to leave too much space behind the tank, the magnesium anode is disposed on the front side of the hot water storage tank. -
Page 13: Installing Air Intake/Exhaust
4.3 INSTALLING AIR INTAKE/EXHAUST Since AQUA HP absorbs heat during operation, it is good to route cooled air (intake/exhaust) to unheated spaces. The appliance will cool the room in which it is located and if it is installed in heated rooms, cooled air should be routed to other rooms or outside. 4.3.1 Installation without air piping The AQUA HP appliance should be installed in a location that is not too heated and can be used for dehumidification and cooling these areas (e.g. -
Page 14: Installation With Air Piping
4.3.2 Installation with air piping If you use piping for airflow into spaces that do not require heating, you can: Use the outside air Using outdoor air, the unit can be placed either in heated or unheated room. Use air from an adjacent room The unit can also be placed in a heated room, but airflow should be directed to an unheated room. - Page 15 Use air from an adjacent room and outside air To supply air to the appliance, branched pipe can be used. In summer, you can use hot air from the outside and in winter you can use the air from the unheated area. UNHEATED AREA HEATED OR UNHEATED Min 50 m...
