•
Fit the Solar hot water outlet connector to the Solar Tank,
using thread tape,
(Point H).
•
Connect the DuoValve (P/N DUO00A) and the water Pressure Limiting Valve (P/N PLV00A) together,
ensuring that the arrows on the valves are towards tank (point C),
using thread tape.
Run a length of
15mm pipe from the Pressure Limiting Valve to the tank. Connect a 15mm pipe from the cold water in (point G) to the
Tempering Valve (Point T), Connect the Solar recycle (point P) on the tank to the solar pump inlet Shut off Ball Valve (Point D).
Run a length of 15mm pipe from the DuoValve (Point C) and connect back to the ‘mains cold water in’ connection.
•
Connect the Solar Collectors together using the connectors supplied.
Use thread tape on the solar collector threaded connections
and grease on the Conetite mating surfaces
(Points M and or N).
Use two spanners to prevent twisting the manifold
.
•
Run a length of 15mm pipe and connect from the Check Valve (Solar Pump outlet connection – point W)
to the Solar Collector inlet connector (Point L). (
use two spanners to prevent twisting the manifold when tightening the
20mm-15mm adapter to the collector
).
•
Run a length of 15mm pipe and connect from the Solar Collector outlet assembly (Point K) to the Solar input on the Solar Hot
•
Water tank (Point G).
•
Electric Boost
– Connect the tank solar hot water fitting (SHW001 – Point F) to the Tempering Valve (Point R).
•
Gas Boost
- Connect the solar hot water fitting (SHW001 - Point F) to the tank and run a 20mm pipe to the Water Inlet connection
on the Gas Booster.
•
Gas Boost -
Connect from the Hot Water outlet on the Gas Booster with 15mm pipe to the Tempering Valve (Point R)
•
Fit the Lower tank temperature sensor receptacle (part of P/N BSR00A) into Point U).
•
Fit the Upper tank temperature sensor receptacle (part of P/N BSR00A) into (Point V).
•
Connect a cold water feed (from point G) to the Tempering Valve (Point T).
•
From the ‘outlet’ connection – (tempered water) of the Tempering Valve (Point S) run a 15mm copper pipe to the Hot water taps.
•
Place the 2 tank sensor probes into their respective temperature sensor receptacles (Points U and V on the tank)
•
Fit the Solar collector probe into (Point K on the Solar Collector) and run the sensor cable back to the Solar controller and plug in.
•
Silicone seal around the sensor cables, only at the entry point to the temperature receptacles.
•
(Note that there is an optional facility to utilise an internal relay within the solar controller to limit the boost element
times to between 11pm and 6am. The boost element must be wired in series through these normally open contacts to
interrupt the Active/Phase wire that powers the element. Please see HWC1 in the Solar Controller Documentation,
available as a download from the Suntrap Website).
• Secure any loose cables with cable ties.
• For all
Gas Boosted Heater system installations – Please see diagram in Section 4, and notes in Section 10
Gas connection must be carried by a qualified tradesperson – refer to the Gas Boost heater manufacturers instructions.
•
Set the Gas Boost temperature to 70 degrees centigrade.
• Check all fittings and tighten as necessary.
13. Completing the Installation (cont)
• Ensure that the DuoValve (Point C) is closed (on the mains water-in pipe)
• Turn on the main water supply.
• Check for water leaks along this mains ‘cold water in’ pipe.
• Turn on the nearest hot water tap fed from the Solar tank (this assists with the removal of air from the system
during initial fill.
• Open the DuoValve (Point C) on the Mains water-in pipe to allow water to enter the Solar tank.
•
Open the purge valve on the Solar Return Inlet connection to the tank (point G) (
very important to
prevent an air lock on initial fill
).
Warning – the water expelled from point G can be very hot and
precautions must be taken. This is best carried out when the Solar Collectors are cool.
• While filling the Solar Tank with water - hold open the 850kpa Pressure and Temperature valve
(Point J) – this also assists with the removal of air during initial fill.
• Also while filling the Solar Tank with water - watch for water to be expelled at the purge valve on the Solar
Return Inlet connection to the Tank point (point G) (water will have now partially filled the on-roof solar
collectors and pipes) –air will ‘hiss’ until water is expelled). When only water flows, close the purge valve.
• When water is expelled from the P and T Relief valve (Point J), let the valve close.
• Allow water to continue to enter the Solar Tank. Water will begin to come out of the hot water tap
previously left open. When there is a steady flow of water, turn off all hot taps. Check for any water leaks.
• Plug the solar pump into the ‘Pump’ socket on the cable which comes from the underside of the Solar Control Unit.
• Plug the Solar Control Unit into a suitable electricity supply, and switch on the Solar Control Unit. The power
light should illuminate. Open the purge valve (Point G). Press
and hold
the PUMP button on the Solar Controller until
the PUMP light flashes and the pump should start. Run the pump for 10 minutes to ensure that all the air is excluded
from the solar collectors. Close the purge valve. Remove the purge valve key (or the removable handle) to a safe place.
• Press the PUMP button on the Solar controller to turn the pump off.
•
Set the Flow Control Valve (Point W) to 1.2 ltr/min.
• Ensure that Silicone seal is around the tank sensor cables but only at the entry point to the temperature receptacle
(for easy sensor removal if necessary).
• When the Solar Collector water temperature sensor (on the roof) detects that the water temperature is 8 degrees
centigrade or more above the tank water temperature, the solar pump will run until the water temperature difference is
5 degrees centigrade. The pump will also run to ensure that a minimum water temperature of 4 degrees centigrade is
maintained within the solar collectors to prevent freezing. The ‘PUMP’ light will illuminate when the pump is running.
• Check for any leaks and take corrective action.
• On electric boost systems switch on the boost electrical supply.
• Look forward to a very efficient and cost effective hot water delivery system, powered by the sun.
