Pre-Assembled Rhino - Installation Manual
Appendix 15: Operating and Check out Procedures
The system should now be installed,
and pressure checked. Before switching the system on, it’s a good idea to
do one final visual inspection. Inspecting down and across the entire system, check that:
•
The fittings and fixtures are primed and cemented properly
•
All valves are installed correctly and in the right positions
•
The system is properly secured to the roof in a manner that will still allow for thermal expansion and
contraction of all components in the linear and lateral directions.
•
Screws and bolts are secure, and penetrations sealed
•
Roof Mounts installed and bolted correctly
•
All pipework has been properly secured and supported
•
For tiled roofs, all Fixing Tracks should be re-positioned evenly to correspond with the front edge of
the appropriate tile to avoid the panel from rubbing against the roof surface.
•
No part of the panel is rubbing against the roof surface or any obstacle. If it is, it may cause damage to
the roof and/or panels
•
The system will automatically drain or that it is installed with manual drain valves
•
The Automatic Controller (if installed) has been tested
•
System appears neat, tidy and of high quality
Appendix 16: Pressure Testing the System
Commissioning the system is one of the most important steps for any solar installation. Performed correctly,
commissioning should highlight any faults within the system prior to hand over. To pressure test the system:
Step 1:
Allow 24 hours for all PVC Cements/adhesives to set prior to commissioning the system. This
time can be used to clean the job site.
Step 2:
Prime the pump by filling the lint pot with water, once filled start the pump via the manual
mode on the Digital controller.
Step 3:
Once primed, air should purge from the system and back to the pool via the pool return
outlet for only a short period of time.
Step 4:
After a minute or two, inspect the pools return outlet. If bubbles continue to flow endlessly,
it may be an indication that air is entering the system via the VacRel
®
.
Step 5:
Once the bubbles reliably stop, check the TufGauge
®
Pressure Gauge is reading between 50
and 100 kPa (7 and 14.5 PSI).
Step 6:
Check the system and panels for leaks. The suggested method is to inspect the roofs surface
for water dribbling towards the gutters. By following the dribbles up the roof, you will
generally find the source of the leak. Repair and re-test as necessary.
Step 7:
Once you are satisfied that the system is running properly, switch it off and listen to the
VacRel
®
. Air should be entering the system through the VacRel
®
and water should be draining
back to the pool.
