Check the flexible tubing for wear. Look for cracking, side splits or other signs of material fatigue. Dam-
aged tubing must be replaced immediately. When tubing is replaced, the pump should be calibrated.
Replacement tubing kits are available through the MID-TECH dealer.
5.7.3 SEASONAL
Replace the flexible tubing before application season begins each year. Calibrate the pump at the start of
each season.
5.7.4 PERIODIC
Check calibration whenever it is suspected the system accuracy has deteriorated, or anytime tubing is
changed.
5.8 OTHER INJECTION PUMPS

At the end of the day, disconnect the pump from the MID-TECH TANK (or turn OFF the valve at the outlet
of the chemical tank), connect the pump to fresh water and flush according to the chemical
manufacturer's directions.
BE CAREFUL THAT WATER OR SEDIMENT IS NOT TRAPPED IN THE INJECTION PUMP, PARTICU-
LARLY IN COLD WEATHER, AS DAMAGE TO THE MECHANISM MAY OCCUR.
5.8.1 SEASONAL:
Calibrate the pump at the start of each season.
5.8.2 PERIODIC:
