SYSTEM OPERATION
SYSTEM OPERATION OVERVIEW
The Force
®
Evo injection system utilizes replaceable chemical boxes housed within the Force
®
Evo cabinet on a
rack system. No chemical tank to refill or rinse between operations.
When the injection system is empty, disconnect and remove the empty boxes from the cabinet racks and replace
with prefilled boxes.
NOTE: Prior to operating the system after installation, it is recommended to flush the injection lines with RV
anti-freeze to rinse out any manufacturing or installation debris and to check plumbing connections
for leaks. Refer to the Flushing the Force® Evo System section on page 13 for details on flushing and
rinsing the injection or carrier system.
During this cleaning procedure, set the 3-way valve to by-pass the point of injection to prevent debris
from plugging the check valves and in-line mixer. Return the 3-way valve to the inject position after
clean-out is completed.
FLUSHING THE FORCE
®
EVO SYSTEM
PROCEDURE TO FLUSH THE INJECTION SYSTEM
IMPORTANT: When working with pesticides and other ag chemicals, personal protective gear must be worn. refer to the
chemical manufacturer’s label for required personal protective equipment. Decontaminate all equipment
before making repairs or storing the implement.
It is normally acceptable to leave chemical that has not reached the point of injection in the injection lines for a
short period. As long as the chemical is not mixed and the injection system remains sealed, the chemical should
remain soluble and flow when the field operation resumes within a couple of days.
If the implement will be stored for part of the season, the injection system must be flushed and rinsed thoroughly.
When storing the implement, it is recommended to winterize the injection pump and chemical lines to help ensure
chemical residues do not damage the injection pump. Refer to the Winterizing the Force® Evo Injection System
section on page 17 for details on winterizing the Force
®
Evo injection system.
NOTE: It is also recommended to flush the injection system prior to the initial operation to rinse out
manufacturing or installation debris.
To flush the injection system:
1. Disconnect and remove the chemical boxes from the cabinet racks. Properly store or dispose of chemical
containers according to the chemical manufacturer’s recommended procedures.
