Step 1:
Close all valves. slowly open Valve No. 4 to relieve pressure. Open Valve No. 6 to drain.
Step 2:
Open Valve No.'s 3, 5, 8, 9 and 11. Observe liquid level in sight gauge.
Step 3:
Add concentrate via fill cup to required level.*
Step 4:
Close all valves and proceed to "shell Water Refill Procedure." Drain sight gauge.

14.0 MAiNTENANCE PROCEDuRES
The bladder proportioning system you have purchased has three (3) main components: a carbon steel AsME pressure
tank, Buna-N® bladder, and a ratio controller. This simple design requires no outside source of energy, other than water,
to proportion foam concentrate.
Despite this basic design, routine inspections, tests, and maintenance should be performed to verify the unit is full and
in operating condition. This routine should extend to all the components which make up the fire extinguishing system
to verify that all are in working order.
Testing and maintenance of these components is covered in Chapters 6 and 7 of NFPA 11, 16 & 25.
14.1 RECOMMENDATiONS FOR MAiNTENANCE AND iNSPECTiONS
1. The designated inspector should be a responsible and experienced person with a basic knowledge of fire-
equipment and the specific fire protection system.
2. Initial test data information is important for reference points.
3. Proper personnel should be notified of shut down for service. This includes, but is not limited to, area work-
ers, alarm company, underwriters, etc.
4. Before working on a CCs tank or any sprinkler riser components, close the manual concentrate valve (No. 1)
and the water pressure valve (No. 2). Be aware that the CCs tank may still be under pressure.
5. Check the general appearance, including name plates and decals, for readability.
6. Inspect for corrosion, leaks, or mechanical damage. Repair and/or repaint where necessary.
7. Verify the concentrate level. Follow the procedure for "Concentrate Level Check" on page 15. If the concen-
trate is lower than recommended, refer to the Refilling Instructions on page 16.
While water is draining from the tank, observe for presence of foam concentrate. A small amount of foam is
not uncommon. Large amounts of foam or pure concentrate can be a sign that further inspection or mainte-
nance is required. Contact Viking for further instructions.
8. Collect a sample of foam concentrate according to the guidelines per Dyne Technologies.
9. Examine all auxiliary equipment in accordance with the manufacturer's instructions; check the electric or
hydraulic isolation valves for operation.
FILL ONLY TO RATED CAPACITY!
NOTE: DRAIN THE sIGHT GAUGE FOLLOWING A LEVEL CHECk.
