9. Clamps and Fixing Collector (Bottom): Ensure the
solar collectors are well seated and centred in the
collector mounting rail.
Collector Rail: Clamp the solar collectors (two clamps
per collector) to the collector mounting rail, using the
clamps and hex screws, washers and nuts provided.
Position the collector clamp over the hole in the
collector rail with the top lip of the clamp over the
collector trim.
Insert the hex screw through the hole in the collector
clamp and collector rail, place the washer and nut on
the screw and screw the nut until it seats firmly against
the lip of the collector rail, applying medium pressure
with a spanner to tighten.
Tank Flashing, Tank to Collector Spacers:
10.
Tile Roof: If used, fit the tank flashing sheet under
the top of the solar collectors and extend up the
roof to the top of the solar storage tank location. Lift
the roof tiles immediately above the solar storage
tank location and secure the flashing sheet to the
roofing members. Ensure the flashing sheet makes
the section of roof under the tank waterproof.
Metal and Tile Roof: Locate the Tank to Collector
spacers (8) against and under the top end of the
solar collectors (one per collector for a two collector
system). These should be located 200 mm from
the sides of the collector for a one collector system
or 200 mm from the ends of the tank for a two
collector system, and on the top of the tile or metal
roof profile.
Solar Frame Installation: Ensure the solar collectors are well seated and centred in the tank / collector rail.
Solar Storage Tank Positioning: Using a lifting device, lift the tank onto the roof. Position the solar
11.
storage tank in place above the solar collectors, locating central to the solar collectors before sliding it
down onto the Tank to Collector spacers or tank / collector rail if the installation is on a solar frame. Centre
the solar storage tank before commencing interconnecting pipe installations.
12. TRV or OTP System
Thermosiphon Restrictor Valve (TRV) is to be fitted
to an 52L system, assemble the cold pipe with the
TRV thermostat element pointing towards the tank
as per marking. If an Over Temperature Protection
(OTP) fitted to an 52H system, refer to the
installation instructions supplied with that systems
parts kit for additional information of the installation
of the over temperature protection components.
Tank to Collector Connections of Pipe Work:
13.
52L direct system: Fit a union body R 3/4 M x G 3/4
M with its internal cone profile facing out, into the
tank socket inlet on the left hand end of the solar
storage tank and one into the tank socket return
connection on the right hand end of the solar
storage tank.
Fit an adaptor union M33 M x G3/4 F and O'ring,
one into collector cold inlet at the bottom left hand
side of the first collector and another into the hot
outlet at the top right hand side of the second or
third collector.
Connection: If a
