2.0 INTRODUCTION

DESCRIPTION

The model EPXN-3 steamer comes equipped with a standard 9 kW heating block that can be
reduced to 6 kW on single phase supplies. Model EPXN-5 steamer comes equipped with a
standard 15 kW heating block that can be reduced to 10 kW on single phase supplies.

Your new steamer has been designed and manufactured to meet the toughest industry
standards. The best possible workmanship and materials along with laboratory tests have been
utilized in its design.

Proper installation, care and maintenance will give you years of reliable, trouble free operation.

The EPXN-3 and EPXN-5 are electric fired pressureless steam cookers. The cooking
compartments are equipped with a three-piece door with inner gasket plate isolated from the
exterior surface. Door latch operates by slam action for positive sealing of the door. Operating
controls are displayed on a front-mounted panel and include indicator lights for ready and
cooking modes, a timer to set cook times and an illuminated rocker mode selection switch for
TIMED COOKING, OFF and CONSTANT STEAM.

BASIC FUNCTIONING

The cooker is ready for operation when the READY light comes on.

At the end of the set interval, timer contacts switch to shut off the cooking operation and sounds
a signal buzzer and will maintain a safe food holding temperature at or above 150EF. The
buzzer is silenced by returning the timer dial to the OFF position. The READY light will be
illuminated.

3.0 INSTALLATION

UNPACKING

Immediately after unpacking the steamer, check for possible shipping damage. If the steamer
is found to be damaged after unpacking, save the packaging materials and contact the carrier
within 15 days of delivery. File a claim regardless of extent of damage.

We cannot assume responsibility for damage or loss incurred in transit.

Prior to installation, verify that the electrical service agrees with the specifications on the
machine data plate which is located on the left side panel.

LOCATING

Allow space for vent and electrical connection. Minimum clearances for proper air circulation is
2" on the sides and 6" on the back. Allow adequate access for servicing.

LEVELLING

Using a spirit level, adjust the feet to level the unit, front to back and side to side. The unit must
be level for proper operation. Warranty will be void for improper installation.

ELECTRICAL CONNECTIONS

WARNING: The unit must be electrically grounded and comply with
local codes, or in the absence of local codes with the national
electrical code ANSI/NFPA to latest edition. Canadian installation
must comply with CSA Standard (C22.2 No. 109-M1981 General
Requirements Canadian Electrical Code, Part II 109-M1981) for
commercial cooking appliances.

WARNING: Disconnect electrical power supply and place a tag at
the disconnect switch to indicate that you are working on circuit.

Use copper wire suitable for at least 200E Fahrenheit (90E Celsius).
The steamer must be grounded. The wiring diagram is located on
the right side panel as you face the unit.

Make electrical connection through the 1-1/8" (29 mm) diameter hole provided using 3/4" (19
mm) trade size conduit. Refer to the wiring diagram located inside the right side panel. Use
90EC minimum insulated wire.

3.0 INSTALLATION (Continued)

PLUMBING CONNECTIONS

No plumbing connections are required as steamer is filled manually.

DRAIN CONNECTIONS

No drain connection is required.

WATER CONDITION

For best results Crown recommends that the water supply meet the following specification:

Hardness: Less than 2 grains or 35 ppm.
Total Dissolved Solids (TDS): Less than 60 ppm.
PH Factor: 7.0 to 7.5

This degree of hardness can easily be obtained with the use of a properly maintained water
softener.

VENT HOOD

Some local codes may require the steamer to be located under an exhaust hood. It is
recommended that this steamer be located under an exhaust hood to remove excess steam
during cooking operations.

Information on the construction and installation of ventilating hood may be obtained from the
standard for “Vapor Removal for Cooking Equipment”, NFPA No. 96 (Latest Edition).

WARNING: For an appliance equipped with casters, the installation
shall be made with an adequate flexible electrical conduit; adequate
means must be provided to limit the movement of the appliance
without depending on or transmitting stress to the electrical
conduit; the location where restraining means may be attached is to
the rear of the stand, below power supply connection.
