REMEDY
7.0 TROUBLE-SHOOTING
9.0 SPECIFICATIONS
Turn the percentage knob to the OFF position. Use the hose, or hose and
straight stream nozzle, to rinse off the PRO/pak. Reset percentage knob to
proper percentage when finished.
For years of service, periodically inspect your PRO/pak. Make sure the hose
and three nozzles are in place. Look for debris in the bottom of the tank and
flush if necessary.
If the PRO/pak is often used for different foam concentrates, it may be helpful
to install a drain to aid in emptying the tank. Drill and tap the left front ear of the
tank and install a ¼" NPT Pipe plug. Plastic or Brass preferred.
