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

ISUAL
NSPECTION
Visually inspect the Dry Acid 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 Dry Acid 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 the repair is made. 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 Fresenius Medical Care Dry Acid 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. All spills should be
wiped off immediately. Spillage at the control panel should be avoided in order to minimize the
possibility of electrical malfunction.

1. To start the disinfection process, power OFF the Dry Acid Dissolution Unit, remove the Filter Housing and
discard the Filter Element. Place the residual fluid from the Filter housing in the Residual Solution Bucket.
Reinstall Filter Housing, but do not insert a Filter at this time. Connect the Transfer Nozzle to the end of
the Dissolution Unit's Transfer Hose and make sure the valve on the Transfer Nozzle is in the CLOSED
position. In addition, loosen the top Access Lid, but leave it in place. Ensure you have the appropriate
personal protective equipment donned.
