MAINTENANCE
1. The main fuse of the ROSCO MODEL 1700 smoke machine is located on the circuit card
inside the machine. NOTE: Be sure to check the specifications when replacing any fuses.
WARNING: DISCONNECT THE ROSCO MODEL 1700 FROM POWER BEFORE
CHECKING OR REPLACING THE FUSE. FAILURE TO DO SO COULD BE
HAZARDOUS AND RESULT IN AN ELECTRICAL SHOCK.
2. After every operation, the siphon hose should be removed from the external reservoir. The
machine should be turned on and fog produced. When there is no more fog coming out of the
machine, the machine should be immediately turned off.
3. After every operation, only after the machine has cooled, it should be wiped with a clean
damp cloth or paper towel. This practice prevents the build up of dirt and dust which may
enter the machine and damage sensitive internal components. Do not use solvents for
cleaning. Soap and water are effective.
4. Before and after the machine is stored for an extended period, the machine should be
properly cleaned. The best method for cleaning is using distilled or de-ionized water. To flush
the machine, turn it on and, when ready to use, put the fluid pick-up tube into a container of
distilled or de-ionized water. Run the water through the machine and flush for three minutes.
The tube should be removed from the water and the machine run until nothing comes out of
the nozzle. The machine should be immediately turned off.
5. During use, operation of all switches and indicator lights should be monitored. Lights that
blink or flicker when they should be on or off, for example, are an indication of problems in
the machine's circuitry.
FOG DISTRIBUTION
The fog distribution in an enclosed area depends on air flow and temperature. Natural air
movement, air conditioning and other ventilation systems will affect movement of the fog.
Test under realistic conditions before using. If a space must be filled very quickly, move the
machine up and down and side to side. To conduct fog to particular areas, use a hose adaptor
and ducting hose (see OPTIONAL ACCESSORIES). Make sure that there is an air space of
2-3 inches between the nozzle and any ducting hose. Do not use ducting hose smaller than 4
inch diameter. The ROSCO MODEL 1700 works properly only in a horizontal position. Do
not tilt the machine during operation.
