PERIODIC MAINTENANCE
All EDIC machines are engineered and built to require a minimum amount of maintenance. But like any machine it does require
some care to keep it in optimum working condition. Careful attention to these maintenance instructions will give you maximum
operating performance and will increase the life expectancy of your machine.
•
Solution Lines & Fitting: Flush the machine at least once a month with a solution of 3 parts water with 1 part white
vinegar in order to neutralize the alkaline residue left by the cleaning solution.
•
Quick Connect Couple: Spray with WD-40 or equivalent lubricant to prevent coupler from sticking.
•
Drain Valve: Apply light oil on gate seals. If machine has to be stored for a prolonged period, leave the gate valve
open.
•
Solution Pump: The same above procedure used on the solution line and fittings applies to the pump.
