Foam Concentrate Injection Hose
Connect a hose from the foam pump inject port to the inlet of the check
valve injector fitting. (See Figure 3-20: “Injection and Bypass Hose Connec-
tions.”)
Figure 3-20: Injection and Bypass Hose Connections
The hose and fittings from the INJECT port to the check valve injector fitting
should have a minimum 1/2” (13 mm) inside diameter and be rated at 500
PSI (34 BAR) working pressure (Aeroquip 2580-10 or equal).
Bypass Hose Connection
A bypass port is provided on the discharge side of the ADT, or a 1/4 turn
bypass valve is mounted on the discharge of the foam pump when the ADT
option is not installed. (See Figure 3-21: “Bypass Valve Assembly,” on page
73.)
The bypass handle must be accessible by the pump operator during normal
operations. (See Figure 3-20: “Injection and Bypass Hose Connections.”)
The bypass is a 3-way directional valve. Determine which port is the
INJECT port and which port is the BYPASS. (See Figure 3-21: “Bypass
Valve Assembly,” on page 73.)
Bypass hose connections are 1/2” (13mm). Hose fittings compatible with all
foam concentrates must be provided. The hose from the BYPASS port is
plumbed to the atmosphere and should not receive HIGH pressure.
