Dawning Talk-How to maintain the filter in the winter.
In order to ensure the normal use of your filter system in the next irrigation season, remind all users to maintain and maintain the filter.
1. Disc filter:
Clean each lamination group first (with acid washing if necessary, such as acetic acid, oxalic acid, etc., and rinse with water after acid washing), and then wipe the sealing ring in the plastic case with a dry cloth and put it back.
2. Sand filter:
A. Open the top cover of the filter tank, check the quantity of sand and gravel filter material, and compare it with the mark on the tank. If the quantity is insufficient, please make up in time to avoid affecting the filtering quality. If there is suspended solids on the sand filter material, please remove it.
B. Please add a pack of chlorine balls to each tank. After 30 minutes, start each tank to backflush twice for 120 seconds.
C. Unscrew the valve marked in the reference picture below, and drain the remaining water in the filter to prevent freezing damage and cracking.
