Fabricate system manifold:
The following components have been provided for the system
manifold fabrication: bypass valve(s) with
1
-
1/4”
socket adapters, solenoid valves with
1
-
1/4”
socket adapters,
1
-
1/4”
tees with sample ports, and
1
-
1/4”
check valves. Following
Illustration 2a piping diagram for single systems, or Illustration 2b for duplex systems, con-
struct system manifold using 1 ¼
”
Schedule 40 PVC pipe
.
Note:
IT IS CRITICAL TO NOT REDUCE ANY MANIFOLD PIPING BELOW 1 ¼
”.
ANY MANIFOLD PIPE SIZE REDUCTION WILL AFFECT SYSTEM PERFOR-
MANCE.
3.
Connect drain line(s) to unit(s).
Remove barbed drain line fitting(s) from parts bag. Apply
Teflon thread seal tape to threads and turn into the female threaded opening on the back side
of control valve(s) and run to a nearby drain (individual drain lines must be run for duplex
units, and these lines must not be tied together). Be sure not to submerse drain line ends into
drain, as a 1 ½
”
minimum air gap must be maintained to prevent potential backflow hazard.
Firmly secure at drain, while maintaining a minimum 1 ½
”
air gap.
4.
Connect control valve(s) to electrical power source.
Connect power cord(s) to a separate
120V, 15 amp ground fault interrupt (GFI) outlet.
