2 Installing the solar station
Installing the solar station on a wall
■Remove front insulation shell.
■The solar pump station forms a single unit with the wall bracket and rear insulation shell. Secure both components as a complete unit at the intended location, working the front and using anchors and screws suitable for the wall construction type.
Installing the relief valve
■The solar station is equipped with a solar safety relief valve which meets the relevant requirements.
■Fit the enclosed relief valve to the outlet of the return instruments above the pump using the 3/4" union nuts. A gasket is enclosed with the solar station for use when installing the relief valve.
■The enclosed discharge connection bracket should be fitted to the safety valve so that there is no risk of scalding should liquid escape. Follow local codes for drainage piping.
The following information should be noted:
■The safety valve must be easily accessible.
■No valves should be placed between relief valve and pump station. The relief valve should be piped to a suitable drain as close as possible to the pump station with no reducing couplings or other restrictions. The piping must be sloping away from the pump station at all times.
■Dirt traps or other constrictions are not permitted between the collectors (field) and safety valve.
Installation, wall bracket for expansion tank: (Lochinvar/TiSUN accessories)
■Fit the wall bracket for the expansion tank (if equipped) to the right of the solar station.
■Ensure that the corrugated stainless steel hose is long enough for the connection between the pump station and the expansion tank, not forgetting the expansion coupling.
Installation, connection lines to tank and collector
A) Piping
■Connect the lines between the solar pump station and tank.
■Connect supply and return lines to the collectors.
B) Clamp ring screw connections
■Refer to Section 3: Technology, installation and commissioning, on page 6.
