OPERATION
If you have carefully followed the steps in this manual, you now have an efficient, professional looking eco-
Spark
®
solar pool heating system. This chapter deals with the final checks before you let water into the
system, high pressure testing of the system, and turning the system on and off.
BEFORE LETTING WATER INTO THE SYSTEM
1
.
Allow the cemented/welded fittings adequate time to dry and cool according to the
manufacturer’s instructions.
2.
Verify that the check valves, control valves and vacuum breaker are installed properly.
3.
Verify that all PPC connectors are tightly fastened.
4.
Verify that all lag bolts are secured and that adequate sealant has been used to prevent any
roof leaks where they are attached.
5.
Make sure that the system drains down automatically when the pump is shut off, or that
manual drain valves have been installed and closed.
6.
Verify that all pipe runs are properly supported.
7.
Pressure test the system as described in the next section
.
HIGH PRESSURE TESTING
High pressure testing the eco-Spark
®
system is essential!
1.
Allow ample time for all joints to dry or cool completely.
2.
Unscrew the vacuum breaker and replace it with the pressure testing assembly.
3.
Connect one end of a hose to the water supply and the other end to the pressure testing
assembly.
4.
Turn on the water supply and wait for the pressure to reach 4–5 bar (60-70 psi).
5.
Check all joints for leaks.
6.
If there are leaks:
a.
Open the ball valve on the return line to relieve the pressure.
b.
Repair leaks.
c.
Repeat the pressure testing procedure as needed.
7.
When pressure testing is complete re-install the vacuum breaker.
