3 1 Important information/safety regulations The cooling module must be installed by authorised installation engineers and the installation must follow the applicable local rules and regulations as well as these installation instructions. This apparatus is not intended for persons (including chil- with reduced physical, sensory or psychological capac- dren) ity, or who do not have knowledge or experience, unless supervised or they have received instructions on how the apparatus functions from a safety qualified person. Children are not permitted to play with the apparatus. Installation must be carried out in accordance with applicable local rules and regulations. NOTE! To prevent leaks ensure that there are no stresses in the connecting pipes! NOTE! It is important that the heating and brine circuits are completely bled after installation. NOTE! leed valves must be installed where necessary. 1.1 Electrical connection Electrical installation may only be carried out by an authorized electrician and must follow applicable local and national regulations. Electrical current! The terminal blocks are live and can be highly dangerous due to the risk of electric shock. The power supply must be isolated before electrical installation is started. The cooling module is connected internally at the factory. 1.2 Commissioning The installation may only be commissioned if the heating system, water heater and brine system have been filled and bled. Otherwise the circulation pumps can be damaged. 2 rea of use The passive/active cooling module, DCM-P, can be used for cooling requirements greater than what can be obtained through only passive cooling (free cooling). For cooling requirements at max. 20 kw. The cooling modules make it possible to retain either passive or passive/active cooling from the rock groundwater collectors. The distribution system for this can be the radiator system (fan convectors) or under floor heating systems. Cooling starts when the outside temperature exceeds the set value for heat stop. 3 For the installer 3.1 Installation The cooling module must be mounted hanging vertically on a wall. The central distance for mounting holes is 530 mm. 530 mm Electrical installation is carried out according to the wiring diagrams found on page Pipe installation is carried out according to the system diagrams found on page Function during cooling operation Stage 1. Passive cooling In order for the heat pump to start passive cooling, the following conditions must be fulfilled: 1. The outside temperature is higher than the setting for heat stop. 2. Room temperature exceeds the desired temperature by the same amount of degrees that the room factor is set to. 3. The above requirements must be met within 5 minutes. The heat pump s internal brine pump starts and circulates the coolant via the cooling module to the bore hole. In the cooling module, the set temperature is shunted out to the cooling system Stage 2. Passive/active cooling (this function are only available on the passive/active module) In order for the heat pump to start passive cooling, the following conditions must be fulfilled: 1. ll conditions for passive cooling must be fulfilled. 2. Room temperature exceeds the desired temperature by twice the room factor. 3. The above requirements must be met for 1 minute. 4. If the in coolant temperature exceeds the desired temperature to the cooling system during passive cooling, active cooling is force connected after 120 seconds The heat pump s compressor starts and the shift valves for active cooling operation are reset. In the first instance, the excess heat is used, which is produced in the heat pump s condenser for hot water heating. When the hot water is heated, the excess heat is shifted down to the bore hole. This provides more favourable operation for the heat pump at the same time as a high cooling effect and good efficiency is achieved. 3
