 TM 9-2320-279-10-3
Operation Under Usual Conditions (Cont)
PANEL).
a. Foam System Activation.
WARNING
Before operating foam system, personnel must
familiarize themselves with all procedures and
instructions regarding water pump, discharge devices,
and foam making devices. Failure to understand and
follow any instructions could result in personal injury
and/or damage to equipment.
Open and close all valves slowly during any
procedure. Sudden changes in pressure may cause
equipment to react faster than personnel can be
alerted. Make sure surrounding personnel are aware
of changes being made to settings on equipment.
Failure to comply may result in injury or death to
personnel and damage to equipment.
CAUTION
When in foam mode, never open TANK FILL and
RE-CIRCULATION LINE valve control. This will cause
foam agent to enter water tank. If recirculation is needed
to keep pump cool, open PUMP COOLER valve.
NOTE
Foam system operation from pump operators panel
requires system pressure of at least 125-250 psi
(862 - 1,724 kPa) for proper proportion.
