Site Selection and Preparation Prior to installation of a Domestic Solar Hot Water System Local Building Codes, Zoning Ordinances, Subdivision covenants and any other special regulations pertaining to the site should be consulted. To find out what’s needed for local compliance, contact the following: Your local jurisdiction’s zoning and building enforcement divisions • Briefly describe your intended construction, asking for other relevant ordinances/codes that might be in effect.
Site Selection and Preparation SYSTEM INSTALLATION AREA The location of the Solar Controller, pumping system and storage tanks can be planned in the same location as your current water heating system. The Dimplex Solar Hot Water System will require an area, in the same area as your current water heating system, which will allow for the 24” (61cm) diameter Solar Storage Tank with approximately 6” (15.2cm) diameter additional clearance, to enable easy access to monitor the system.
Site Selection and Preparation board or a “mounting wall”. For the double wall system installation the wall area required is approximately 4’ x 4’ (122 cm x 122 cm). For the single wall system installation the wall area required is approximately 2’ x 4’ (61 cm x 122 cm). CAUTION: Protection against auto-ignition of combustibles: Combustible materials used in soar equipment and adjacent structures shall not be exposed to an elevated temperature that could cause ignition.

Commissioning ! NOTE: The cold water supply line to the Solar Storage tank should be insulated with R-4.2, 1” (2.5cm) thick, for a minimum distance of 5’ (1.5m) or to the wall if it is less than 5’ (1.5m). 2. Install an isolation valve on the outlet of the Solar Storage Tank and add a Tee connection to the existing piping into the existing water heating system. 3. Install an Anti-Scalding valve on the outlet of the backup water heating systems before distribution throughout the house.
Operation arning: If the outdoor temperaW ture is expected to drop below the rated temperature range of the heat transfer liquid, drain the heat transfer liquid out of the system until the threat is no longer present. Solar Collectors There is no specific operator action required. Piping There is no specific operator action required. Pumping Station - Solar Loop-A arning: CHECK THAT ALL VALVES ARE W ORIENTED IN THE APPROPRIATE DIRECTION BEFORE STARTING THESE INSTRUCTIONS. see figures 18 & 19.
Operation ists. ! NOTE: If there is some air accumulated, open the air separator long enough to release the air. Then run the system for a little while and open it again to ensure that all of the air has been removed. • Temperature Gauges The system is equipped with two temperature gauges to monitor the temperature of the fluid travelling to and from the Solar Collector Panels.
Operation HXA Expansion Tank There is no specific operator action required. Figure 22 Solar Storage Tank Main Menu The Solar Storage Tank is equipped with a pressure relief valve. The activation pressure of the pressure relief valve is 29 psi (2 bar). Although the valve is set for 29 psi (2 bar) as the pressure release, the normal operation of the unit will be 14.5 psi (1 bar).
Operation Information Menu The Information Menu is the main menu for automatic regulation of Solar Hot Water System. It indicates current system values, the current system condition, any error messages and the number of operating hours. The table below indicates the readings in the Information Menu and whether they can be reset to assist in monitoring the system. Using the and buttons will allow the user to toggle through the displayed values. Indication Reset Description E.g.
Operation Description Solar Storage tank: Maximum Permissible temperature Indication Value range Default e.g. Settings 59-185°F 149°F max. 149°F (15-85°C) (65°C) Solar Storage tank: switch-on difference dT max 13°F 5-72 °F (3-40°C) 13 °F (7°C) Solar Storage tank: switch-off difference dT min. 5°F 4-30 °F (2-17°C) 5 °F (3°C) min. 100 30%-100% 100% Set the minimum pump capacity using the RPM control 100% = RPM control off To change the values: • Toggle through to the setting to be changed.
Operation set maximum temperature and the Solar Collector temperature exceeds the Solar Collector Protection setting (Line 1) the pumping stations will be switched on and will continue to run until the Solar Collector Temperature is 18°F (8°C) below the set maximum tank temperature. In this case, the Solar Storage Tank is charged up to 250°F (121°C) regardless of the set maximum temperature.
Maintenance Warning: Always completely disconnect the device from the power supply before performing maintenance or electrical work. The Solar Hot Water System should be monitored on at least a monthly basis, by checking system pressures, flows and temperatures to ensure that they are within normal operating range. These ranges can be found in the Operation Section of the manual and the Warranty Sheet.
Maintenance Sheets for pH range of solution. If the pH is outside of the range the solution should be replaced. ! NOTE: It is suggested that you change the distilled water at the same time that you change the Polypropylene Glycol, if equipped with a HXA Pumping Station. See Decommissioning Section for Polypropylene Glycol removal from system.
Maintenance arning: The water in both of the tanks is hot W enough that it could scald. 4. Close the Household Water isolation valve. 5. Turn on a hot water faucet to relieve pressure from the system. 6. Turn on another faucet, to allow air into the system. 7. Open the drain valve at the bottom of the Solar Storage Tank and drain approximately 2 gallons (7.5 liters) of water from the tank, so that when the rods are removed water does not splash out of the hole. 8. Unthread the Anode rod from top of tank.
Decommissioning arning: Always completely disconnect the W device from the power supply before performing maintenance or electrical work. Warning: The decommissioning must be carried out by a trained, qualified person and must be recorded in writing. The technical documentation must be kept with the equipment. The following instructions can be used for replacing Fluids, fixing failed components or disassembling the system.
Decommissioning Loop and HXA, or associated piping can be performed. 14. To empty the Solar Storage Tank, open the pressure relief valve on the top of the unit. 15. Open the drain valve at the bottom of the Solar Storage Tank and empty tank. 16. All of the sections of the Solar Hot Water System can now be disassembled.
