1.
Ensure that all electrical connections are OFF, secure, and not exposed to elements or potential
leaks.
2.
If start up is during the day please ensure the collectors are covered so as not to introduce cold
water into a hot collector. This could flash to steam cause scalding and damage to the system.
3.
Open pressure relief valve to vent the storage tank to atmosphere.
4.
Open the mains water line and begin filling the tank/collectors.
5.
Once water starts coming out of pressure relief valve close valve and pressurise system.
6.
Check each of the connections for leaks.
7.
Remove covering from solar collectors.
8.
Set mixing valve to desired temperature.
9.
Turn electrical element on and set to desired temperature. (EL models only)
10.
Ensure pressure relief valve is closed and is piped to a safe location as it may operate in over
temperature conditions causing hot water to be expelled and high pressure.
5.1.1
Expected Temperatures
During normal operation, the system will experience temperature on the inlet and outlet approximately:
-
Inlet temperatures to the collector avg 55°- 60°C (130°-140°F)
-
Outlet temperatures to the storage tank avg 75° - 80° (165° - 175°F)
5.2
Maintenance
5.2.1
Solar Collector Cleaning
The solar collectors do not require any maintenance; however, annual checks of the glass and
connections should be made to ensure there are no leaks, cracks etc. At this time, the glass can be
cleaned with a mild detergent if needed.
5.2.1
Hardware
It is recommended that all hardware is checked and tightened annually and/or after any sever weather.
5.2.2
Scale prevention in solar collectors
The solar collectors need to be flushed out using descaling solution once a year to ensure performance
and reliability. This is due to the fact that potable water is being heated directly in the collector and the
presence of CaCO3 (Calcium Carbonate) which precipitates out of water at temperatures above 50°C
(122°F) and can reduce heat transfer, lower flow rates and cause system failure if not treated. Failure to
follow these recommendations will void manufacturer warranty.
1.
Isolate tank and shut off mains water.
2.
Turn off electric connection to the system if applicable.
3.
Cover the collectors to prevent heating descaling solution.
4.
Remove the inlet and outlet connections to the collector using crescent wrench.
5.
Using a descaling solution or other chemical for removing CaCO3 connect a hose to the inlet and
outlet connections.
6.
Using a small circulating pump circulate descaling solution through the collectors for minimum
30 mins.
