Prewet & Anti-Ice System Checklist.

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.

  1. Its like you read my mind! You seem to know so much about this, like you wrote the book in it or something.
    I think that you could do with some pics to drive the message home a little bit,
    but instead of that, this is magnificent blog.
    An excellent read. I will definitely be back.
