Ansul 100/30 User Manual

To provide maximum assurance that the ANSUL system will
operate effectively and safely, maintenance must be per-
formed at six-month intervals, or sooner when indicated by
an inspection.
NOTICE
The nitrogen cylinder regulators must be tested
annually using Regulator Test Kit (Part No.

Test section, Page 12. To ensure that regula-
tors will operate properly during maintenance,
perform the regulator test before performing
maintenance procedures.
1. Note general appearance of the system and component parts,
checking for mechanical damage or corrosion.
2. Check nameplates for readability, corrosion, or looseness.
3. Read nitrogen cylinder gauge, note pressure, check ambient
temperature, and refer to Temperature Correction Chart on
Page 16. Replace cylinder if below minimum pressure.
NOTICE
If cylinder requires replacement, refer to
Re charge Section, steps 11 through 14.
4. Check dry chemical tank by completing the following steps:
Be careful when removing fill cap(s) as tank(s) may be pres-

• If fill cap vent starts relieving pressure while opening the fill
cap, stop and let all pressure vent before removing cap.
• If fill cap is difficult to remove, pressure must be relieved
from tank.
Refer to page 4, steps 1 - 5 to confirm tank pressure is
released. Attempting to remove fill cap when tank has pres-

c. Inspect threads in fill cap and on fill opening for nicks, burrs,
cross-threading, and rough or feathered edges. Clean and
coat fill cap threads lightly with a good grade of high heat-
resistant grease.
d. Make certain AFFF solution level is within 3 in. (76 mm)
from bottom of the fill opening.
