Cleaning Preparation
WARN NG
PRESSURIZED FLUID HAZARD
This equipment stays pressurized until pressure
is relieved manually. To help prevent serious
injury from moving parts, or from pressurized fluid,
such as skin injection, splashing in the eyes or on
skin, follow the Pressure Relief Procedure in your
system manual when you stop pumping and efore
you clean, check, or service the equipment.
PERSONAL PRO EC IVE EQUIPMEN
Wear appropriate protective equipment when
in the work area to help prevent serious injury,
including eye injury, hearing loss, or inhalation of
toxic fumes.
This procedure involves thoroughly disassem ling
and cleaning the individual parts in the pump lower.
Prior to performing these procedures:
1. Flush the pump and relieve pressure as
descri ed in the system manuals.
2. Disconnect all hoses.
3. Remove the pump from the system.
Notes:
• Be sure to follow your national and state sanitary
standard codes and local regulations.
• Use appropriate cleaning and disinfecting agents,
at intervals appropriate for product processed.
• Follow cleaning product manufacturer’s
instructions.
Cleaning the Air Motor
