The GranuFlo I Dissolution Unit is designed for ease of use and trouble-free operation. However, a minimal
amount of preventive maintenance is required in order to maintain the GranuFlo I Dissolution Unit in good
working condition and minimize the possibility of a system malfunction.
The recommended program for proper care of the GranuFlo I Dissolution Unit consists of four basic steps.
They are: (8.1) Regular visual inspection, (8.2) Cleaning, (8.3) Sodium Hypochlorite (Bleach) Disinfection, and
(8.4) Filter Maintenance.

I
NSPECTION
Visually inspect the GranuFlo I Dissolution Unit prior to mixing a batch. The Operator should look for
any defects which may inhibit the safe or proper operation of the Unit. Items such as damaged
hydraulic hoses or fittings, damaged electrical cables or connections, loose, missing or damaged
hardware, or process contamination should be corrected prior to the use of the GranuFlo I Dissolution
Unit.
Should the power cord or plug become cracked, frayed, or otherwise damaged, it should be replaced
immediately. Tag Unit “OUT of SERVICE” until repaired. Always remove the power cord from the power
source before attempting to service this device. Never unplug the Unit by pulling on the power cord.
8.2 C
LEANING
Clean the exterior surface of the GranuFlo I Dissolution Unit thoroughly after each batch of concentrate
is mixed. If necessary, a mild detergent solution may be used to clean the exterior surface. Care should
be taken not to contaminate the system interior. Wipe all spills immediately. Avoid spillage at the
control panel to minimize the possibility of electrical malfunction.
