CAUTION
Safety glasses should be worn during transfer operations
of ANSULEX Low pH Liquid Fire Suppressant. Avoid
contact with skin or eyes. In case of contact, flush immedi-
ately with water for 15 minutes. If irritation persists, contact
a physician. Do not take internally. If taken internally do
not induce vomiting. Dilute with water or milk and contact
a physician.
Pour the liquid agent from the tank into a clean, plastic
container, and flush tank with clear water.
10. At this point, each liquid agent tank, including the 1/4 in.
gas hose assembly, must be HYDROSTATICALLY
TESTED to 330 psi (26.6 bar). Refer to “Hydrostatic Test
Instructions,” F-7602, for test adaptors and instructions.
NOTICE
DO NOT hydrostatically test a red painted
mild steel agent storage tank. Instead,
replace the tank with a new stainless
steel tank shipping assembly (3 Gallon
(Part No. 429862) or 1.5 Gallon (Part No.
429864)).
11. Verify date stamped on cartridge. The cartridge must also
be hydrotested at intervals not greater than 12 years.
(European cartridges are not refillable, therefore cannot be
hydrotested and refilled. They must be discarded).
12. If cartridge date indicates the need for hydrotesting, the
cartridge must be bled down through normal AUTOMAN
release operation, returned to Tyco Fire Protection Products
for credit (or hydrotested by properly trained personnel at
authorized cartridge refilling stations), and replaced with a
charged, replacement cartridge.
NOTICE
Cartridge bleed down can be used to
verify pneumatic accessories operation.
13. If system contains an Agent Distribution Hose and
Restraining Cable Assembly, a hydrostatic test is required
at 220 psi (15.2 bar) for hose assembly.
14. The regulator must be flow tested at 12 year intervals.
Check the date code stamped on the regulator body to
determine if the regulator(s) requires the 12 year testing
(see data code table). If regulator does not require testing,
proceed to step 12. Flow test the regulator(s) per the follow-
ing table:
