1. 45 FOR INSTALLING AND USING Solarfill 2 thermal filling set Solarfill 2 operating instructions Introduction The Intaeco Solarfill 2 is a solar thermal filling set designed to make the filling and flushing of aqueous glycol based systems easy Solarfill 2 features a robust trolley type design with swivel wheels allowing it to be easily manoeuvred into position in the plant room Key features Increased capacity 30 litre solar fluid tank with large lid for easy filling New 0 5 Hp pump Reduced noise level during operation Filling port with shut off ball valve and flexible connection hose Flushing de aeration port with shut off ball valve amp flexible hose Clear large capacity bowl filter replaces old Y strainer Pressure gauge High output filling pump with cast iron body and brass manifold Variable pressure regulator to set fill pressure Inlet for connection to an external tank Optional manual pump for pressurising without electrical power By employing the Solarfill 2 cleaning draining venting and filling of pipe systems is made much easier and can take place in a single operation It s also no longer necessary to work on the roof adjacent to the solar array and solar air vents on the roof can be omitted from the system design System debris can also be flushed out through the inbuilt strainer Instructions for use Filling method ball valve closed solar fluid in Pressure gauge2. air amp debris outy Bowl filter re ee AA AE Pp isolation valve Inlet when tank is not Filling pump used with isolation valve Solarfill 2 operating instructions Read before operating Solarfill 2 Never run the pump set unmanned Avoid running the pump without fluid Hot fluid returning from the collectors can pose a scalding risk Temperatures can exceed 60 C On sunny days cover the collectors or avoid filling the system during the hottest part of the day Ensure the flexible connection pipes are fitted to the correct connections on the pump set and system Only use on aqueous and aqueous glycol systems If required clean or flush the solar fluid tank with the strainer open Use bund trays and avoid operation with wet hands Filling and flushing These instructions should be used in conjunction with the instructions for the components contained within the solar thermal installation Before filling and flushing carry out system checks and ensure the solar expansion vessel has the correct gas charge 1 Securely fit the connection hoses to the solar thermal system Use the connections on the solar pump Station if installed 2 When using the integral tank use a funnel and a bund tray and carefully fill the integral tank When using IBC or external solar fluid containers or tanks dip the flexible inlet hose in the container 3 Depending on the source of the fluid either open the isolation valve below the integral t
