RECHARGE (Continued)
6.
CAUTION
Do not flush pipe with only water or other non-approved
material, as this could cause internal corrosion, leading to
possible improper discharge.
Piping system must be flushed to remove any wet chemical
residue. To prepare the system for flushing:
a. Pour the complete contents of one 32-oz. bottle of ANSUL
Flushing Concentrate (Part No. 79656) into an empty
R-102 agent tank. One complete bottle is used for either
size tank, the 1.5 gallon or the 3 gallon.
b. Fill the tank approximately half full with warm, clean water.
Agitate the tank for a few seconds and then add more
warm water to bring the fill level to within approximately
1 in. (25 mm) from the bottom of the fill opening.
c. Install adaptor/tube assembly and tighten.
7. To perform the flushing procedure, either secure heavy-duty
plastic bags to each nozzle (See Figure 7-2) or remove
each nozzle tip and strainer and attach plastic tubing. See
Figure 7-3.
If using plastic bags, secure bags and proceed to Step 9.
If using plastic tubing, proceed to Step 8.

8. If using the plastic tubing option, utilize 1/2 in. (13 mm) OD
plastic tubing with wall thickness not to exceed 0.062 in.
(1.5 mm), and make certain it can withstand the pressures
of at least 90 psi (6.2 bar) expelled during the flushing and
blowdown procedures.
Also required is a container with some means of securing
tubing to it such as a five-gallon plastic pail and cover that
snaps onto the pail.
To prepare the plastic tubing:
a. Cut as many tubing lengths as required, making them
long enough to reach the container from each nozzle
outlet.
b. Using the nozzle tip end, slide a length of 1/2 in. (13 mm)
plastic tubing over the rib on the nozzle tip and secure
with a 1/2 in. (13 mm) adjustable hose clamp. See Figure
7-4.
c. In the pail cover, drill the number of holes required, large
enough to insert 1/2 in. NPT fittings, with one additional
hole that can be used for venting.
d. Secure 1/2 in. compression fitting/threaded adaptors to
the pail cover, using 1/2 in. conduit nuts. See Figure 7-4.
