START UP PROCEDURE
To Make Foam - Connect water supply. Attach the desired nozzle to
the Quick-Connect. Turn the Percentage Knob to the desired
percentage. Twist the Valve Handle to start water flow.
Attach inlet fire hose to the coupling on the inlet end of the PRO/pak. Larger hoses may be used with an adapter. For maximum
maneuverability, we recommend attaching 1" hose into the PRO/pak itself.
Unscrew the fill port lid by turning counterclockwise. Fill tank to bottom of fill port. Foam may seep out the vents if over filled. Close the
fill port lid by turning clockwise. Set the selector wheel on the lid to indicate type of foam in the tank.
6.1 HOSE CONNECTION
6.2 FILLING TANK
1. Select the appropriate nozzle from the molded compartments on the side of the PRO/pak tank.
2. The nozzle may be attached directly to the quick-connect fitting on the control block or to the end of the outlet hose which is then
attached to the control block. Align the marks on the quick-connect male fitting with the marks on the female fitting and push the two
pieces together. Twist the nozzle or hose one quarter turn to the right to latch the quick-connect fitting.
3. Longer hose is available. TFT part U-HS6, U-HS12 and U-HS25.
6.3 CONNECT DISCHARGE HOSE AND NOZZLE
The PRO/pak's eductor will not work if the backpressure from the outlet hose or nozzle is too high. The 25'
(7.5m) U-HS25 optional hose is the maximum length that will work with the PRO/pak. Adding additional
hose, or using other hose assemblies and nozzles, may cause the PRO/pak to not function properly.
There is no check valve in the PRO/pak eductor system. Do not install a shut off valve between the PRO/pak
and the nozzle. This can cause the foam tank to fill with water and dilute the foam concentrate.
CAUTION
CAUTION
Remove the nut on top of the percentage knob and lift the knob to select the proper foam concentrate type. Replace the knob nut. Turn
the knob to the desired concentrate percentage. The percentage knob may be turned to the OFF position for water only use. Be sure
to use the foam manufacturer's recommended concentrate ratio.
6.4 SETTING FOAM CONCENTRATION
Pressurize the hose line. Turn the flow control valve to start water flowing through the PRO/pak. Flow may be reduced by partially
closing the control valve.
6.5 CONTROLLING FLOW
Foam quality with the Medium Expansion Nozzle will depend upon the velocity of the foam solution exiting the nozzle. When pumping
high pressures to the PRO/pak it may be necessary to partially close the flow control valve to make good foam with the Medium
Expansion Nozzle. If the foam exiting the Medium Expansion Nozzle is not a coherent continuous stream, close the flow control valve
slightly until the foam becomes a coherent continuous rope-like stream.
