4.
Check fluid pressure gauges to ensure proper
pressure balance. If imbalanced, reduce pres-
sure of higher component by slightly turning
Recirc/Spray valve for that component toward
Recirc, until gauges show balanced pressures.
The pressure imbalance alarm (Status Code 1)
is inactive for 10 sec after entering spray pres-
sure mode, to allow time to balance pressures.
Watch gauges for 10 sec to be sure pressure
.
holds on both sides and pumps are not mov-
ing.

On impingement guns, never open fluid mani-
fold valves or trigger gun if pressures are
imbalanced.
