8 SHURFLO WATER BOOST MODULAR FILTRATION SYSTEM INSTALLATION AND OPERATION GUIDE
SYSTEM STARTUP AND OPERATIONS CONTINUED
Filter Replacement and System Maintenance
It is recommended to install new filter cartridges as part of the routine preventive maintenance service or on the event that
there is inadequate water outlet supply (see list below) to the dispense system.
Inadequate water outlet supply to the dispense system is revealed by one or more of the following symptoms:
• Excessive noise from carbonator pump during cycle.
• Excessive cycle time to refill carbonator tank.
• Insufficient water flow rate from non-carbonated dispense valve.
• Low dynamic water outlet pressure from WBMF system.
The first three conditions above are apparent by simple observation of the fountain system while in operation.
The last condition is revealed following the procedure below.
Dynamic Water Outlet Pressure Check Procedure
1. Allow water boost pump to cycle off.
2. Adjust red needle on filtered water pressure gauge to the
low-pressure side of the black needle.
The WBMF system must now be put under dynamic water
demand for accurate reading of the gauge.
3. Disconnect QCD fitting on one(1) BIB carbonated
brand syrup.
4. Activate one (1) dispense valves of disconnected syrup
brand at each dispenser being supplied by the water
boost modular system simultaneously until carbonator
cycles. Allow carbonator to cycle off.
5. Check pressure reading of red needle on pressure gauge.
6. Replacement of the filters is recommended if the red needle
has fallen into the midrange of the colored wedge area.
Note: Bypass sump caps are located on the bottom of each sump and can be temporarily installed on system in place of
filters if replacement cartridges are not available.
Filter Replacement and Preventive Maintenance Procedure
1. Disconnect all power supplies to the carbonators being
fed by the system being serviced.
2. Disconnect power supply to the water boost pump.
3. Turn the inlet and outlet globe-valves to the off position.
City water supply should be left in the on position to main
water supply to icemaker.
4. Uncoil purge valve tubing and put into bucket or drain.
5. Turn the purge valve to the open position until all water is
purged from accumulator tank and system.
6. Turn the purge valve to the off position.
7. Rotate each filter stainless steel sump assembly ¼ turn
counterclockwise by hand only to release from filter head.
8. Remove and discard used filter cartridge.
9. Remove existing (filter cartridge) installation decal from
stainless steel sump.
Check model number of
new filter cartridges with
cartridge being replaced for
correct application match. Installation Decal
10. Remove installation decals from the new filter cartridges
being installed.
11. Record installation date on decals and apply to stainless
steel sump housings.
12. Insert new filter cartridges into stainless steel sump
(check for puck at the bottom of stainless steel sump before
inserting cartridge).
13. Insert filter sump assembly into filter head by aligning
tabs and then rotating filter sump assembly ¼ turn
clockwise to secure into proper position.
Pre charge and safety relief should be checked for proper
pressure and operation before restarting the system.
14. Locate Schrader valve on end of accumulator tank remov-
ing Schrader valve cap and check tank for proper pre
charge pressure adding additional pressure if necessary
using air only or nitrogen.
Pre charge of 50 psi is
recommended for carbonated
beverage applications.
Do not pre charge the
accumulator tank with CO2.
15. Open and close pressure relief safety checking for
proper functioning.
16. Position the purge valve vent line into a bucket or drain.
17. Turn the inlet globe-valve to the ON position. Leave the
outlet globe-valve in the OFF position.
18. Reconnect power supply to the water boost pump.
