STEP 2
Loosen a tube fitting or cover plug at the main valve to allow air to
vent during start-up (See Image 5 and 6).
STEP 3
Pressure the line, opening the upstream isolation valve slowly
(Labeled #1 in Figure 2). Air is vented through the loosened fitting.
Tighten the fitting when liquid begins to vent.
STEP 4
Slowly open downstream isolation valve to establish flow through
the system (Labeled #2 in Figure 2).
