SHUTDOWN PROCEDURES
1. CLOSE the
Manual Valves
by turning them to the full clockwise position.
CAUTION!
Excessive force closing or opening Manual Valves may
result in damage to the Manual Valves and/or Coupling Block.
2. With the purge air on, use the supplied
Grease Gun
(Pg.
40) to lubricate the
Mixing Chamber
through the
Grease
Fitting
until a fine mist of grease is sprayed from the gun
(Pg. 43 for Grease Gun Assembly Instructions). This action
will help prevent Isocyanate from crystallizing on the mixing
chamber which may cause damage to the internal parts.
NOTE!
The injection of grease supplied with the Gun
at the end of the day will minimize maintenance time
and can eliminate the need to remove the Mixing
Chamber each day to clean it. Use of grease with
high moisture content will not achieve the
desired results. PMC Grease is recommended.
Use of incorrect grease will cause blockage in
the mixing chamber.
3. Disconnect the air supply.
