Air Gap Requirements; Valve Drain Requirements - Whirlpool WHELJ1 Installation And Operation Manual

AIR GAP REQUIREMENTS

A drain is needed for Clean Rinse discharge water. A
floor drain, close to the Central Water Filtration
System, is preferred. A laundry tub, standpipe, etc.
are other drain options. Secure valve drain hose in
place. Leave an air gap of 1-1/2" between the end of
the hose and the drain. This gap is needed to prevent
backflow of sewer water into the Central Water
Filtration System . Do not put the end of the drain
hose into the drain.
The Commonwealth of Massachusetts plumbing
code 248-CMR shall be adhered to. A licensed
plumber shall be used for this installation.

VALVE DRAIN REQUIREMENTS

Using the flexible drain hose (included), measure and
cut to the length needed. Flexible drain hose is not
allowed in all localities (check your plumbing codes). If
local codes do not allow use of a flexible drain hose, a
rigid valve drain run must be used. Purchase a com-
pression fitting (1/4 NPT x 1/2 in. minimum tube) and
1/2" tubing from your local hardware store. Plumb a
rigid drain as needed (see Figure 4, below).
NOTE: Avoid drain hose runs longer that 30 feet.
Make the valve drain line as short and direct
as possible.
It is recommended that the Central Water Filtration
System be installed near a drain. However, if a drain
is not available, it is still possible to operate the
Central Water Filtration System in.a manual Clean
Rinse mode. See "Operating in Manual Clean Rinse
Mode" section. The automatic Clean Rinse function
must be disabled if the Central Water Filtration System
will not be connected to a drain.
