DISCHARGE PIPING (AFTER REGULATORS)
(Continued)
Installation of Water Tank Pressurization Piping
Water tank pressurization is accomplished using the
factory-set water pressure regulator attached to the high
pressure manifold.
1. Install piping from the water pressure regulator to the
water tank location as shown in Figure 10.
Note:
Piping should include a master shut-off valve, a
relief valve, and a manifold.
2. For each water tank, verify that the flow arrow on the
check valve at the tank pressurization inlet is pointing
towards the tank.
3. Connect each tank to the manifold using a flexible hose
(Part No. 72584) and adapter fitting (Part No. 25582).
Attach swivel adapter to the manifold. Attach flexible
hose to the water tank assembly. Connect flexible hose
to the swivel adapter on the manifold.
Note:
A maximum of four 50 gal (189 L) water tanks
can be pressurized with a single regulator. For systems
requiring more than one regulator, regulators must be
piped in parallel to a common water tank pressurization
manifold. For one water pressure regulator, use 3/8 in.
piping. For two water pressure regulators, use 1/2 in.
piping.

Installation of Water Discharge Piping
The water discharge piping connects the tanks to the atom-
izers according to the piping layout determined in the
design of the system.
1. Manifold the outlets of the tanks together using
selected discharge pipe size as determined in the
system calculations. See Figure 11.
2. Install water shut off valve to the outlet of the manifold.
Note:
For 3/4 in. pipe, use the 3/4 in. shut-off valve
(Part No. 435805). For pipe sizes greater than 3/4 in.,
use the 1 1/2 in. shut-off valve (Part No. 437341).
3. Install remaining pipe according to the piping layout
determined in the system design.
4. Using a compressed gas supply, blow-out the entire
water discharge piping assembly to remove any foreign
particles prior to connecting the atomizer.
5. Connect pipe to the atomizers using the 1/2 in. NPT
inlet connection on the atomizer.
