Verify all portions of the refrigeration sys- tem are operational. Re-start associated compressors that were turned off in steps above. Repeat this Maintenance Procedure for each float switch that has a liquid make- up system without a drain valve configu- ration, starting with Task # 1 “Preparing for Float Switch Testing.” If this is the last float switch to be tested today, cleanup your work area. Secure your equipment and prepare to document your work. Continue to Task # 3 “Documenting Float Switch Testing.”
