INSTALLATION

BUILDING CODES AND STANDARDS

The steamer must be installed in accordance with the following building codes: USA: National Electric Code, ANSI/NFPA-70, state and local codes. Canada: Canadian Electric Code, CSA C22.2 and local codes.

UNPACKING

This steamer was inspected before shipment from the factory. The shipping company accepts full responsibility for safe delivery. Immediately after unpacking, check the steamer for possible shipping damage. If damage is identified, saving the packaging material and contact the shipping carrier within 15 days.

LOCATION AND PLACEMENT

To insure maximum benefit of your warranty; location, placement and leveling are critical. The AccuTemp Steam ‘N’ Hold steamer is designed for installation on either a commercial kitchen countertop or an AccuTemp Steam ‘N’ Hold stand. Your Steam ‘N’ Hold steamer is equipped with vents to allow the proper ventilation of air through the electrical compartments. On current S6 & S3 Steam ‘N’ Hold models, the vents are located on the bottom and rear panels. To ensure these vents work properly, a minimum 4 inch (102 mm) clearance from these vents must be allocated. It is also recommended that the Steam ‘N’ Hold not be placed under other wet equipment or locations.

Note:

rear face and left side panels. A minimum spacing of 6 inches (152 mm) to the left side access panel is required between heat sources such as, but not limited too, a range, griddle or fryer. A minimum spacing of 3 inches (76 mm) to the rear face, between any object such as a wall, barrier or other piece of equipment, must be allocated as well.

LEVELING

The steamer must be installed in a level condition. An out-of-level condition may cause improper operation and possible damage. Damage caused by improper leveling is not covered by warranty. Use a spirit level, resting on the top steamer cabinet surface, to ensure it is level front-to-back and left-to-right. If this is a counter-top installation, be sure to install a rubber foot tip

provided with your steamer onto the foot adjuster of each of the steamer leg as shown. This will keep the steamer from sliding on the counter-top under normal

use. Once the rubber foot tips have been installed, rotate the foot adjusters up or down as needed to level the steamer.

For S6 models with a serial number lower than 22627, vents are located on the

WARNING

When using a stand that is equipped with casters, the floor surface must be level and flat. Failure to do so can result in a “tipping” situation that could result in serious injury.

ELECTRICAL SUPPLY

The AccuTemp Steam ‘N’ Hold steamer has been designed, manufactured and tested to meet or exceed the Underwriters Laboratories safety standards. To ensure safety is maintained in your installation, it is important that the following paragraphs are understood before attempting to apply power to your Steam ‘N’ Hold. If there is any doubt as to whether your supply receptacle is of the correct voltage, amperage, or is properly grounded, consult a qualified electrician or serviceman.

POWER REQUIREMENTS

AC power requirements are listed on the data plate located on the left side access panel on all steamers. Steamers should never be connected to a circuit operating at more than 150 VAC to ground and should always be connected to an individual branch circuit. Make sure the voltage at the supply receptacle is within ±10% of the voltage listed on the steamer’s data plate. Connection to any other voltage may permanently damage your Steam ‘N’ Hold or cause premature component failure. Damage of this type is not covered under the product warranty. Each Steam ‘N’ Hold steamer comes equipped with a connected 6 foot power cord and plug, rated for the power requirements of each steamer. Damage caused by removal or modification of factory standard plug is not covered by product warranty.

GROUNDING

To reduce the risk of serious shock or death in the event of an electrical short circuit, this appliance must be grounded. The Steam ‘N’ Hold steamer is equipped with a cord having a grounding wire and plug, which must be plugged into a receptacle that is properly installed and grounded. Under no circumstance should the grounding plug be cut or bent to fit a receptacle other than the one specified.

DRAIN CONNECTION

While there are no AccuTemp-supplied drain components, some customers may desire to construct a drain connection. Any drain connections must include an air gap between the steamer and the drain to avoid creating a back siphon effect into the steamer cooking compartment.

HOOD VENTILATION

Some local building codes may require the steamer to be located under an exhaust hood. Please check local building code requirements before completing installation of the steamer.

INITIAL START-UP

!

INTRODUCTION

The AccuTemp Steam ‘N’ Hold steamer takes the time-proven method of cooking with steam and adds the advantage of control. This is accomplished by reducing the internal atmospheric pressure of the Steam ‘N’ Hold cooking chamber, thereby lowering the temperature at which the water begins to boil. This allows the operator to control the temperature of the steam for cooking. Controlling the steam temperature gives the operator the ability to cook the food to the desired temperature without over-cooking, resulting in a more tender, juicier, nutritious product and with less shrinkage than was previously possible. Once the cooking time expires, the steamer automatically enters the “Hold” mode. In this mode, the thermostat regulates the internal temperature, but vacuum is released, returning the cooking chamber to normal atmospheric pressure. At this time, steam is no longer generated and the cooking chamber is held at the desired temperature at a relative humidity of 100%. This eliminates food from drying out by suppressing the evaporation of the products’ natural moisture. As a result, most food products can be held in a ready-to-serve state for several hours after cooking, with no appreciable loss in taste, appearance or consistency.

DAILY PREPARATION FOR USE

Preparing the Steam ‘N’ Hold for use each day requires very little time and effort: simply fill the steamer with water and preheat.

Caution Before filling the cooking chamber with water, ensure that the drain valve on the front of the Steam ‘N’ Hold is in the closed position. Ensure that a full size steam table pan or a 1/1 gastronome pan with a minimum depth of 4 inches, has been positioned on the pan rail brackets under the steamer.

At the beginning of each day, open the door of the Steam ‘N’ Hold and pour 3 gallons (11 liters) of ordinary tap water into the bottom of the cooking chamber. (Although the mineral content of the water is not that important, the Steam ‘N’ Hold should always be drained and cleaned at the end of each day to prevent food or mineral buildup.)

INITIAL START-UP (cont.)

!

Daily water usage will depend on several factors: cooking temperature, the products being cooked and the length of time the door is open. In most cases, 3 gallons (11 liters) of water will last several hours or more. However, the level of the water should be checked periodically to avoid running low and or out. If the Steam ‘N’ Hold does run out of water, the “Low Water” warning indicator light and buzzer will turn on. Should this occur, simply turn the Steam ‘N’ Hold off, refill it with water and restart the unit. If the shutdown occurred during cooking, the cycle will resume at the point it stopped. However, a time adjustment may be necessary, depending on the temperature of the water the steamer was re-filled with.

CAUTION

Do not use the low water warning indicator light and buzzer as substitutes for checking the water level in the cooking chamber periodically. Failure to properly maintain the water level may result in improperly cooked product and over time may result in a premature service issue that may not be covered under warranty.

AUTO-FILL MODELS

The Steamer must be connected to the facility water supply via an appliance hose, preferably a stainless steel braided hose with a ¾” garden hose type connection, from a water spigot or from a nearby sink faucet.

First time fill (the Steamer water reservoir is empty of water):

1. With the water supply turned on, press the “ON” button. The Steamer will power up with the pump operating.

2. Both water valves will be turned on.

3. A relay will bypass the low water level sensing to allow for first time filling of the reservoir.

4. The thermostat will be turned off for the first fill to prevent damage to the heater elements.

5. Water will rise to the low level probe and reset the low level circuit of the water control board.

6. The water will continue to rise until it contacts the High Level Probe.

7. A five second delay is initiated when the water touches the High-level probe to allow for wave action in side the water reservoir.

lower than desired amount of water to be injected in the reservoir by tripping the control too soon if there were no sequence to ignore the wave action inside the reservoir.

8. When the five seconds has been satisfied the water level control board shuts off the water level control relay and the by pass relay.

9. The heater is turned on and normal operation begins.

WARRANTY

LIMITED WARRANTY

One Year – Parts and Labor

U.S. & Canada Only

AccuTemp Products, Inc. (AccuTemp) warrants that your AccuTemp equipment will be free of defects in material and workmanship under normal use for a period of twelve (12) months from installation or fifteen (15) months from date of shipment from AccuTemp, whichever date first occurs (the Warranty Period). Registration of AccuTemp equipment is required at the time of installation. Damage to AccuTemp equipment that occurs during shipment must be reported to the carrier, and is not covered under this warranty. The reporting of any damage during shipment is the sole responsibility of the commercial purchaser/user of such AccuTemp equipment.

AccuTemp provides an active service department, which should be contacted and advised of service issues, regardless of the warranty period. During the warranty period, AccuTemp agrees to repair or replace, at its option, F.O.B. factory, any part which proves to be defective due to defects in material or workmanship, provided the equipment has not been altered in any way and has been properly installed, maintained, and operated in accordance with the instructions in the AccuTemp Owners Manual. During the warranty period, AccuTemp also agrees to pay for any factory authorized equipment service agency (within the continental United States and Canada) for reasonable labor required to repair or replace, at our option, F.O.B. factory, any part which proves to be defective due to defects in materials or workmanship, provided the service agency has received advance approval from AccuTemp factory service to perform the repair or replacement. This warranty includes travel time not to exceed two hours and mileage not to exceed 50 miles (100 miles round trip), but does not include post start-up assistance or training, tightening of loose fittings or external electrical connections, minor adjustments, maintenance, or cleaning. AccuTemp will not reimburse the expense of labor required to replace parts after the expiration of the warranty period.

Proper installation is the responsibility of the dealer, owner-user, or installing contractor and is not covered by this warranty. Improper installation can affect your warranty. Installation is the responsibility of the Dealer, Owner/User or the Installation Contractor. See the Installation section of the Owners Manual. While AccuTemp products are built to comply with applicable standards for manufacturers, including Underwriters Laboratories (UL) and National Sanitation Foundation (NSF), it is the responsibility of the owner and the installer to comply with any applicable local codes that may exist.

AccuTemp makes no other warranties or guarantees, whether expressed or implied, including any warranties of performance, merchantability, or fitness for any particular purpose. AccuTemp’s liability on any claim of any kind, including negligence, with respect to the goods and services covered hereunder, shall in no case exceed the price of the goods and services, or parts thereof, which gives rise to the claim. In no event shall AccuTemp be liable for special, incidental, or consequential damages, or damages in the nature of penalties.

This constitutes the entire warranty, which supersedes and excludes all other warranties, whether written, oral, or implied.
