INSTALLATION
• Please read all instructions and precautions before installing and using
your GRO-475B/GRO-475M.
• For standard, under-sink installation on 3/8" (9.52 mm) steel, brass, or
copper cold water line.
• When selecting a mounting location of the system and tank, take into
consideration the length of tubing required for connections between existing
plumbing and system components. Some installation sites may require
more tubing than provided in the kit.
• Numbered diagrams correspond with numbered steps.
1. Installing the Water Supply Adapter
The supply adapter fits 1/2"-14 NPS supply threads or
3/8" x 3/8" compression. If local codes permit, it may be used to connect the
system to the cold water supply line. If local codes do not permit the use of the
supply adapter, alternate connectors can be obtained from your local supplier.
Directions:
(A) Turn off cold water supply line. If cold water line does not have a shut-off
valve under the sink, you should install one.
(B) Turn on the cold water faucet and allow all water to drain from line.
(C) Disconnect riser cold water supply valve.
(D) Ensure the sealing gasket is fully seated into the feed adapter valve female
thread.
(E) Install feed adapter valve onto supply valve as desired. The feed adapter valve
may be installed at the bottom of the supply hose or the top of the cold water
line. Hand tighten only.
(F) Connect the riser to the feed adapter valve.
NOTE: Be careful not to cross-thread.
The 1/4" red drain tubing includes a
WARNING:
