Below is a checklist to make sure your liquid equipment is functional and ready to go for that first winter storm event.
Prewet & Anti-Ice System Checklist.
. Install any liquid system components that were removed from truck for summer
. Inspect all components for damage, especially spray nozzles
. Inspect inside of pump enclosures for standing liquid, corrosion
. Inspect and clean liquid quick disconnects
. Inspect inside of liquid tanks and flush with clean water as necessary
. Inspect and dielectric grease all electrical connections
. Partially fill tanks with water or prewet fluid
. Position all hand valves for normal operation
. Run pump manually to verify proper operation of pump and motor
. Operate diverter valve to verify operation (if applicable)
. Operate anti-ice lane valves to verify operation (if applicable)
. Adjust aim of spray nozzles if necessary
. Check calibration values in the spreader/liquid controller
. Check lovejoy coupler between hydraulic motor and prewet pump for excessive wear.
. Flow meters on prewet and anti ice systems must be clean and free of debris for proper operation
. Check operation of the pump pressure relief system. It is either a separate relief valve or it is built into the pump. A malfunctioning bypass system will cause damage to both the pump and the flow meter if the nozzles become plugged.
. After testing of any liquid system, drain all water and replace with anti freeze prior to usage.
