WATER CONNECTIONS
It is the responsibility of the purchaser to install and maintain
the water supply to the m oven . Failure to provide
satisfactory water quality to operate the oven properly
can cause damage to integral components and void your
warranty .
This oven must be installed to comply with the applicable
federal, state, or local plumbing codes .
Water supply connection to the m is made via a
1/8” NPTF fitting at the rear of the oven . The ability to move
the oven for service and cleaning may be a consideration
when choosing the type of connection and supply line to be
attached at this fitting .
The m water delivery system includes a water
pressure regulator that has been pre-set to operate at 20 psi .
The water supply must maintain at least 20 psi and a flow rate
of three gallons per minute for proper operation of the oven’s
moisture injection system .
Water Quality Requirements
Garland recommends that the supply water be filtered before
it enters the oven’s water delivery system . This will extend the
life of the oven and its water delivery system components by
minimizing particles in typical tap water sources that cause
scaling and build-up of mineral deposits .
The recommended minimum water quality standards,
whether treated or pre-treated, and based on 10 hours of use
per day, and daily cleaning ./descaleing are as follows:
Total dissolved solids – less than 60 parts per million, total
alkalinity – less than 20 parts per million, silica – less than 13
parts per million, chlorine – less than 30 parts per million and
a pH Factor greater than 7 .5 .
Consult a local water treatment specialist for an on-site
water analysis for recommendations concerning feed water
treatment (if required), in order to remove or reduce harmful
concentrations of minerals . The use of highly mineralized
water will cause more frequent cleaning and reduce
operating efficiency . The fact that a water supply is potable is
not proof that it will be suitable for moisture mode operation .
Component failure/service related to poor water quality will
not be covered under warranty .
Spray/Flex Hose W/Quick Disconnect
Your m oven may be equipped with the optional
spray/flex hose assembly . The spray/flex hose assembly is
intended to assist in cleaning the oven . The water pressure
and velocity may vary, depending on the pressure and
velocity of the water supply connected to the oven .
Drain
Your m oven has a gravity drain in the right rear
corner of the oven cavity . The drain pipe that exits the rear
of the oven must be directed downward toward the floor,
and should run directly to an open floor drain . Garland
provides an 1-1/2” male pipe adapter for connecting your
drain lines . Avoid using flexible hose that could sag or kink,
allowing water to accumulate . The drain must be vented . This
connection must be at least 1-1/2” (38 .1 mm) in diameter and
configured in accordance with local codes .
