INSTALLING THE WATER SUPPLY
MODEL MO24RF WITH OPTIONAL ICE-MAKER KIT
An optional ice-maker kit (part number S42418151) is avail
-
able for model MO24RF which includes all of the necessary
parts for installation. The kit can be obtained from Marvel
customer service by calling 800-223-3900.
Water Supply
Observe and follow all local building codes when installing
this appliance.
Use
1
⁄
4
" copper tubing for your water supply which is avail-
able at any local hardware or plumbing supply store. Bend
the
1
⁄
4
" copper tubing to suit your installation being sure not
to kink the tubing. Purchase enough copper tubing length
and coil it behind the unit to form a "service loop" which will
allow the appliance to be pulled out from the installation for
servicing or cleaning. Connect the copper tubing to the "top
side" of a cold water pipe to prevent the ice-maker from
plugging with sediment.
A shutoff valve is recommended on the water supply line to
ease servicing the appliance.
NOTE: A SELF-PIERCING
TYPE VALVE IS NOT RECOMMENDED
as they are prone
to clogging with sediment which will create pressure drop
reducing the water supply to the unit.
Connect the copper tubing water supply to the brass union
with the compression nut fitting provided. (See Figure 7).
Water pressure must be at a minimum of 20 psi for proper
operation and a maximum of 120 psi.
Make certain all water connections are watertight after in-
stallation. Form the tubing so that it will not vibrate against
the cabinet body or kink when your appliance is set in posi-
tion.
