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.
SL-PS Installation & Operation Manual
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.
