Installation Notes:

��

• Counter-mounted equipment

shall be designed to be sealed

to the counter, table, raised

base, or shelf.

• Each oven deck requires a

separate electrical connection.

��

• Garland recommends a

separate 30 amp circuit be

provided for each oven.

��

• Customer must provide a

1/4" NPT water connection

capable of 20 psig (minimum),

to 100 psig (maximum).•

Garland recommends the

following minimum water

conditions:

60 ppm coral dissolved solids,

20 ppm alkalinity, 13 ppm

silica, 30 ppm chloride, pH

factor greater than 7.5.

��

• Customer must provide a ﬂoor

drain or similar device.

• It is the responsibility of the

purchaser to install and

maintain the water sup-

ply to

��

the moisture+ oven.

Failure to provide satis-

��

factory water quality to

operate the oven properly

can cause damage to inte-

gral components and void

the warranty.

��

is oven must be

��

installed to comply with

applicable federal, state,

or local plumbing codes.

panel/body side section.

Installation of the wiring must be made in accordance

with local codes, and the National Electrical Code,

ASNI/NFPA 70-1990, or in Canada, the Canadian

Electrical Code in regards to:

Electrical Connection

Before attempting the electrical connection, the rating

plate should be checked to conﬁrm that the oven’s

electrical characteristics and the electrical supply are

compatible. e plate is located on the inside surface of

the control panel/body side.

1. Switch panel size

2. Overload protection

3. Wire type

mineral deposits.

It is recommended that your supply water not exceed

any of the following parameters: 60 PPM total dissolved

solids; 20 ppm alkalinity; 13 ppm silica; 30 ppm chloride;

PH factor of 7.5.

Consult a local water treatment specialist for

recommendations regarding your water supply system

and its use with this oven. e use of highly mineralized,

(‘hard’), water could negatively aﬀect the quality of

products prepared using the oven. e potability of

supply water does not guarantee its suitability for use

with the moisture+.

Water supply connection to the moisture+ is made via

a 1/4” NPTF ﬁtting at the rear of the oven. e 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.

e moisture+ water delivery system includes a water

pressure regulator that has been pre-set to operate at 10

psi. e 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.

Drain

Your moisture+ oven has a gravity drain in the left rear

corner of the oven cavity. e 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.

Avoid using ﬂexible hose that could sag or kink, allowing

before beginning the cleaning procedure.

Tools: Digital thermometer with probe; oven mitt.

See also, Temperature Calibration on page 12.

2. Wipe exposed cleanable surfaces when cool with

a mild detergent and hot water. Stubborn residue

spots may be removed with a lightweight non-

metallic scouring pad. Dry thoroughly with a clean

cloth.

1. Clamp the probe in the center of the middle rack.

2. Pass the probe wire out of the oven between the

door and the door seal and close the door.

CLEANING AND MAINTENANCE

Oven Cleaning

Motor Care

• e motor in this convection oven is maintenance

Interior

free since it is constructed with self-lubricating

sealed ball bearings. It is designed to provide durable

service when treated with ordinary care. ere are a

few suggestions to follow on the care of the motor:

• NOTE: Disconnect the oven from the power supply

before cleaning or servicing.

• Establish a regular cleaning schedule. Any spills

should be wiped oﬀ immediately.

• When the motor is operating, it cools itself

internally by air entering at the rear of the motor

case, provided proper clearance has been allowed.

Tools: Supplied spray hose; brush; cloth

• NOTE: e spray hose connection is located behind

the front control panel. When cleaning the oven

interior, attach the supplied hose to the water connector

behind the control panel.

• Since the blower wheel is in the oven cavity, it is

at the same temperature as the oven. If the motor

is stopped while the oven is hot, the heat from the

blower wheel is conducted down the shaft and

into the armature of the motor. is action could

shorten the life of the motor.

1. e oven should be allowed to cool suﬃciently

before beginning the cleaning procedure.

2. Remove the racks, rack guides, and the baﬄe. Wipe

each with a clean, damp cloth.

• It is recommended that at the end of a bake or

roasting period, when the oven will be idle for any

period of time or before shutting down completely,

the door be left open slightly and the “ON/OFF”

button pressed to put the oven into Auto Cool

Down. Once the internal temperature of the oven

falls below 150°F (66°C), the fan will stop running

and the display will show “OFF”. is feature

protects the oven motor from pre-mature failure.

Optimal cool down will be achieved with the door

open slightly.

3. Using the supplied spray hose, spray the inside of

the oven lightly to remove any deposits.

4. Wipe the interior with a clean damp cloth to remove

any remaining deposits and spots.

5. Brush the wheel as needed to remove any grease

and/or particles.

6. Carefully wipe the blower wheel and temperature

probe with a clean damp cloth.

7. Replace the baﬄe, rack guides, and racks. Return

the spray hose to its storage compartment.
