Tank to Collector Connections of Pipe Work: Connect the solar hot pipe (10) and the solar cold pipe (9)
to the solar collectors, using the
O’rings (11) provided.
Connect the solar hot pipe (10) (short pipe) supplied to the fitting adaptor connection on the right hand
end of the solar storage tank and to the top right connection of the solar collectors.
Connect the solar cold pipe (9) (long pipe) supplied, to the cold water connection on the left hand end of
the solar storage tank and to the bottom left connection of the solar collectors.
Refer also to the Water Connections End
– Exploded View diagram
on page 33 for the location and
position of the solar cold pipe (9) connection to the solar storage tank.
Where supplied, a thermosiphon restrictor valve (28) is to be fitted into the solar cold pipe (9B, 9C).

The shorter solar cold pipe (9B) connects to the solar storage tank. The longer solar cold pipe (9C)
connects to the solar collector.

Position the thermosiphon restrictor valve (28) between the two solar cold pipes, orientating the valve
with the marked arrow pointing toward the tank, and fit a flat silicone rubber washer (29) on either
side of the valve against the flared pipe ends.

Hand tighten the fittings on the solar cold pipes to secure the thermosiphon restrictor valve (28) in
position, then tighten with a spanner, half a turn only to prevent damage to the washers.
Refer to
“Coupling Cold and Hot Pipes to Collector – Screwed Fittings”
on page 41.
After connecting the tank to collector pipe work, check and tighten the nuts (15) on the collector
clamps (16) if required at the collector rail (6) to secure the solar collectors.
12.
Tank Clamps and Roof Straps: On a pitched roof installation, insert a roof strap (4) into a tank clamp (5)
and then loosely attach the tank clamp (5) to the rear foot of the tank base. Attach the upper part of the
tank clamp (5) and secure with the hex screw (14), washer (36) and nut (15) provided. There are two tank
clamps (5) per tank. Ensure the hex screw heads fit into the valley of the roof material profile.
Refer to
“Hooking Roof Strap to Tank Clamp”
and diagrams on page 39.
Note: AS/NZS 3500.4 states a minimum of three (3) screws 40 mm long be used per roof strap. Longer
screws or anchors may be required to achieve a 40 mm minimum embedment into rafters for a metal roof.
Additional screws or anchors may be required.
Tile Roof: Remove the tiles on the next row above the position of the storage tank to expose the rafters.
Once in position, fix the roof straps (4) directly to the rafters. Replace the tiles.
Metal Roof: Once in position, fix the roof straps (4) to the rafters, through the metal roofing material.
Note: Fixings must penetrate only through the high point in the roof material profile.
