RACK ASSEMBLY
NOTE:
Items in this section refer to Figure 4.
CAUTION:
Maximum load for the Rack System is
750 lbs. (340 kg). This system is designed
for indoor use only.
NOTE:
Each UVBB-1 housing assembly can process up to
15 gpm (57 L/min). Up to four assemblies may be
installed on the Rack System. Four housing
assemblies may be plumbed in parallel (See Figure 6)
to obtain a maximum flow of 60 gpm (227 L/min).
NOTE:
Each attachment point requires a Bolt (Item 8), two
Flat Washers (Item 7), and a Nut (Item 6).
1. Attach the Feet (Item 1) to the bottom of each
Leg (Item 2).
NOTE:
Snug, but do not tighten the bolts and nuts connecting
the legs and top to the Corner Braces (Item 4) until
assembly has been squared.
2. Attach two corner braces to the upper end of each leg.
3. Attach the Leg Brace (Item 3) to the back of each leg.
4. Attach the Top (Item 5) to the corner braces.
5. Square top to the legs. Tighten all 16 nuts securing corner
braces.
INSTALL UV SYSTEM TO RACK
NOTE:
Items in this section refer to Figure 5
NOTE:
Figures 5 and 6 provide examples of configurations
that may be applied to your
PURA
system. These
configurations are not intended as a representation of
a specific system to be installed.
1. Determine location for installation of the Rack System with
housing assemblies. Three requirements for
consideration are: access to cold water line, access to
power, and proper inlet/outlet connection for each housing
assembly.
NOTE:
Each UV control module has its own cord.
A power strip may be required if multiple UV
control modules are installed on Rack System.
2. Install the Rack System. Unit may be attached to surface
or left freestanding.
3. Secure each Mounting Adapter Plate (Item 11) and
UV head to Rack System with Lag Bolts (Item 10) and
Flat Washers (Item 9).
NOTE:
To install a system in “SERIES” as shown
in Figure 5, connect all heads together with
nipples prior to installing heads on Rack System.
4. Plumb heads for specific configuration using proper fittings
and thread sealing tape.
NOTE:
See Page 6 for UVBB Assembly and Activation
Procedures to complete installation.
