INSTALLATION INSTRUCTIONS – CLOSED CIRCUIT SERIES

!
!

WARNING: THE TANKS AND COLLECTORS ARE HEAVY. IMPROPER LIFTING TECHNIQUES COULD
RESULT IN PERSONAL INJURY DURING INSTALLATION. IT IS THE INSTALLER‟S RESPONSIBILITY TO
USE ONLY APPROVED LIFTING AND SAFETY DEVICES AND TECHNIQUES WHEN LIFTING COLLECTORS
AND TANKS ON ROOFS.
WARNING: DO NOT REMOVE THE SOLAR COLLECTOR PACKAGING COMPLETELY PRIOR TO THE
INSTALLATION AS THE SOLAR COLLECTOR SURFACE CAN BECOME VERY HOT. THIS WILL ASSIST IN
PREVENTING POTENTIAL PERSONAL INJURY AND ALSO PREVENT PREMATURE HEATING OF THE
HARTGARD SOLUTION PRIOR TO COMPLETION OF THE COMMISSIONING PROCESS. REMOVE ONLY
SUFFICIENT PACKAGING MATERIAL TO ENABLE THE INSTALLATION OF THE SOLAR COLLECTORS.

Select the location of the storage tank. The front mounting foot of the tank should be positioned directly over a tile batten.
Remove several tiles to expose the rafters and this batten.
Measure down 2050 mm (1270 mm for 301 & 221 Closed Circuit System) from the centre of the batten to determine the
location of the collector rail (refer to drawings, Page 51), mark this location. Remove several roofing tiles from this
location to expose the rafters. If more than two solar collectors are installed, locate the additional collector rail from the
parts kit adjacent to the first collector rail and join together using the drive cleat supplied in the parts kit.
Note: The collector / tank straps are to be fitted to the collector rail(s) before fixing the straps to the rafters.
Determine which slots in the collector rail(s) will be used for the collector straps. Hook two collector straps to the first
bottom collector rail and one collector strap to each additional single collector rail (short) (if used). Refer to “Hooking
Collector / Tank Strap to Collector Rail” on page 51 and Detail A on page 51.
Line up the straps with the rafters. After positioning the rail level, raise the left hand side 12 mm for each collector fitted
(i.e. 12 mm for a single collector system, 24 mm for a two collector system, 36 mm for a three collectors etc) and fix the
straps to the rafters. Replace the tiles.
Move back up to where the storage tank is to be positioned. 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. Place the flashing over this row of tiles and
tuck the top of the flashing under the row above.
Now using a lifting device, lift the collectors onto the roof and place them carefully into the collector rail. Remove the red
transit plugs from the collector sockets.
Join the collectors together using the collector connector assemblies (Part No. 33-7121). On systems that use conetite
fittings, ensure the fittings are fully inserted into the sockets before tightening the nuts. Only medium spanner pressure will
be required. The conetite fittings should be used only once. If for any reason, assemblies with conetite fittings need to be
removed, replace them completely with new assemblies.
Fit the fill assembly (Part No. 33-7134) and the collector bung assembly (Part No. 33-7135) into the bottom left and top
right hand corners (respectively) of the left and right hand collectors (respectively) using medium spanner pressure.
Centralise the collectors on the rail, and lock the collectors to the rail with the collector clamps (2 per collector) and
tighten, using the nuts and bolts provided.
For roof installations, slide the tank-to-collector spacers (Part No. 33-7144) over the top of the collectors. These should be
located 200 mm from the outer edge of the collectors, and on a high spot of the tiles (or profile for metal roofs).
Now using a lifting device, lift the tank onto the roof. Place the tank onto an aluminium flashing (if used) and locate the
tank central to the collectors before sliding it down onto the spacers.
Secure the tank to the roof rafters in a similar manner to that for the collectors, using the tank straps (Part No. 20-4600) and
the aluminium clamps (Part No. 33-0872). Loosely attach the tank clamps to the rear foot of the tank base, and clip in and
bolt the tank straps. Refer to “Hooking Collector / Tank Strap to Tank Clamp” and drawings on page 52. Ensure the bolt
heads fit into the valley of the tile.
Remove the yellow instruction label from the cold pipe. Fit the cold pipe first at the right hand side of the tank and insert
the other end of the pipe to the lower collector s
