SAFETY & PRECAUTIONS
INSTALLATION INSTRUCTIONS
6.
Remove the caps on the bottom valves using an adjustable wrench. Using a 5 mm Allen key, place key
inside of the bottom and turn counter-clockwise slowly until you reach a stop. Open valves in order as
per figure 7.2. Then screw the cap back on the top of the valve and tighten to ensure a proper seal.
Repeat the same procedure for the rest of the zones.
WARNING
NOTE:
The conical ring on the valve has a sealing function with the sealing seat in the caps. Take
precaution not to damage the cone and keep it free of dirt and other debris.
7.
After steps 1-6, double check that all connections are properly sealed using leak detection spray or
soap suds. If bubbles form, the system has a leak, and the screw connectors must be tightened again
using an open-ended wrench. (Refer to Step 11 on page 31 on Checking for Leaks)
NOTE:
• If the system is installed using the quick connect method there is no need to pull a vacuum.
• If the system is installed using flare fittings then a vacuum should be pulled.
24
Failure to properly open the valves before operation will cause damage
to the unit and will void your warranty.
