Page 9 INSTALLATION AND USER MANUAL 200TDHW 6. PLACING 200TDHW The place where the system will be installed should allow an easy access in order to make maintenance work or inspection. Beside these factors, it is important to take into account the following indications regards the installation site: The system has been designed and manufactured for it indoors utilization. In case the system has to be placed outdoors, it must be protected against the adverse weather conditions (direct solar radiation, rain, snow…) Try to place 200TDHW as near as possible of the panels’ installation, and also near to the buffer tank. Installer must install the supplied Silent blocks to avoid the transmission of vibration. 7. CONNECTION BETWEEN 200TDHW AND PANEL 7.1. Join refrigerant pipes Panels are supplied with two nuts for the inlet and outlet connection. The inlet to each panel is 1/4 inch diameter. The installer has to insert the nut into the copper pipe, flare the pipe and then use the nut to fit it. Repeat the procedure with the outlet connection using 3/ 8 inch copper pipe. Then, join the suction line that comes from the panel to the coolant inlet of 200TDHW, and the liquid line to the coolant outlet. The connections are threaded, if welding is needed, weld by oxyacetylene welding. IMPORTANT (Only when welding is needed): It is recommended to weld pipelines by oxyacetylene welding. Welding is a critical step in the installation and to do it well ensures that the system will run properly along its useful life. Only expert staff should make this step by using proper tools and high quality materials. 7.2. Nitrogen test and cleaning procedure In order to check the tightness, introduce nitrogen by using the pressure gauge already installed into load ports. V0REV1EN0218...
Page 10 INSTALLATION AND USER MANUAL 200TDHW CAUTION: Never exceed a nitrogen load greater than 10 bars. Use leaking detector fluid at every welding and even in panel’s connections to verify the absence of leaks. 7.3. Vacuum Connect the vacuum pipe to the pressure gauge to carry out a vacuum of the whole installation. 7.4. Coolant filling Open the load ports to fill the circuit with the refrigerant loaded into the system. 8. HIDRAULIC CONNECTION The hydraulic connections are shown in the following scheme: The installer must install the following components of the hydraulic circuit: Ball valves (1) V0REV1EN0218...
