Section 1: Sacksafoam 1 Overview
Introduction
This manual provides helicopter operators with important information on the operation and maintenance of
the Sacksafoam I dispensing system for use with the Bambi bucket.
Please read this manual prior to flying the bucket, particularly the sections on installation, filling and dis-
pensing. If problems are experienced, please refer to the manual. Section 6
Troubleshooting
may be espe-
cially helpful.
For your own protection and for longer system life, always heed the instructions and warnings. Ignoring
them could result in damage to the Sacksafoam I, Bambi bucket, aircraft or personal injury.
The Sacksafoam I has a number of advanced features to enhance the efficiency of helicopter fire fighting:
•
The control box has a quartz digital timer to control delivery of an accurate percentage
of foam concentrate. The timer circuit has crowbar over-voltage protection and its own
circuit breaker. The system supports a mixer, if required.
•
The sack containing the foam concentrate mounts in the Bambi bucket. This eliminates
spillage and possible corrosion damage associated with carrying foam concentrate
inside the helicopter. An internal check valve stops water from flowing into the sack
and insures that foam is dispensed only while the injection pump is operating. Because
the foam in the sack displaces the water in the Bambi bucket, the total payload is always
constant.
•
An optional foam transfer pump for easily filling the Sacksafoam I is available from
SEI Industries. This portable pump greatly facilitates the filling of the Sacksafoam I
and is powered by 24 volts DC, either from the aircraft or from an auxiliary power
source.
•
The operation of the Sacksafoam I can be quickly mastered by users with no prior expe-
rience. Several dumps with foam will provide familiarity with the use of the system.
SEI offers complete parts supply and repair facilities for the Sacksafoam I. For maintenance and repair pur-
poses, parts diagrams and descriptions are provided in Section 9
Parts.
When ordering parts, please provide
the model and serial number of the sack (which are stamped into one of the fender washers at the bottom of
the sack).
Additional copies of this manual are also available from SEI Industries Ltd.
