IMPORTANT SAFETY INFORMATION

Read the following important safety information before using this equipment to avoid serious injury or death and to avoid damage to equipment or property.

WARNING

ELECTRIC SHOCK HAZARD:

• Plug unit into a properly grounded electrical receptacle of the correct voltage, size, and plug configuration. If plug and receptacle do not match, contact a qualified electrician to determine and install the proper voltage and size electrical receptacle.
• Turn OFF power switch, unplug power cord, and allow unit to cool before performing any cleaning, adjustments, or maintenance.
• DO NOT submerge or saturate with water. Unit is not waterproof. Do not operate if unit has been submerged or saturated with water.
• Unit is not weatherproof. Locate unit indoors where ambient air temperature is a minimum of 70°F (21°C).
• This unit is not “jet-proof” construction. Do not use jet-clean spray to clean this unit.
• Do not steam clean or use excessive water on unit.
• Do not pull unit by power cord.
• Discontinue use if power cord is frayed or worn.
• Do not attempt to repair or replace a damaged power cord. The cord must be replaced by Hatco, an Authorized Hatco Service Agent, or a person with similar qualifications.
• This unit must be serviced by qualified personnel only. Service by unqualified personnel may lead to electric shock or burn.
• Remote control enclosure must be mounted on vertical wall and installed in vertical position. Mounting remote control enclosure in horizontal position may result in collection of liquids and lead to electric shock.
• Use only Genuine Hatco Replacement Parts when service is required. Failure to use Genuine Hatco Replacement Parts will void all warranties and may subject operators of the equipment to hazardous electrical voltage, resulting in electrical shock or burn. Genuine Hatco Replacement Parts are specified to operate safely in the environments in which they are used. Some aftermarket or generic replacement parts do not have the characteristics that will allow them to operate safely in Hatco equipment.

FIRE HAZARD: Locate unit a minimum of 1″ (25 mm) from combustible walls and materials. If safe distances are not maintained, discoloration or combustion could occur.
Make sure food product has been heated to the proper food-safe temperature before placing on the unit. Failure to heat food product properly may result in serious health risks. This unit is for holding preheated food product only.
Make sure all operators have been instructed on the safe and proper use of the unit.
This unit is not intended for use by children or persons with reduced physical, sensory, or mental capabilities. Ensure proper supervision of children and keep them away from the unit.

WARNING

This unit has no “user-serviceable” parts. If service is required on this unit, contact an Authorized Hatco Service Agent or contact the Hatco Service Department at 800-558-0607 or 414-671-6350.

CAUTION

BURN HAZARD: Some exterior surfaces on unit will get hot. Use caution when touching these areas.

• Locate unit at proper counter height in an area that is convenient for use. The location should be level to prevent unit or its contents from falling accidentally and strong enough to support the weight of unit and contents.
• Do not operate built-in models without control box mounted properly as described in installation instructions.
• Do not operate unit without installing supplied legs.
• The National Sanitation Foundation (NSF) requires that units over 36″ (914 mm) in width or weighing more than 80 lbs. (36 kg) either be sealed to or raised above installation surface. If unit cannot be sealed at the point of use, 4″ (102 mm) legs are included to allow for proper cleaning access below unit.

NOTICE

• Unit is designed and recommended for use in or on metallic countertops. Damage to any countertop material is not covered under the Hatco warranty. For other surfaces, verify with manufacturer that material is suitable for prolonged temperatures up to 200°F (93°C).
• Do not modify wiring or cut thermostat capillary on control enclosure to increase remote mounting distance. Cutting thermostat capillary will cause unit to overheat and may damage unit as well as surrounding countertop.
• Do not use excessive force when tightening mounting screws on built-in units. This may damage unit and/or countertop.
• Do not lay unit on the side with the control panel. Damage to unit could occur.
• Use non-abrasive cleaners and cloths only. Abrasive cleaners and cloths could scratch the finish of the unit, marring its appearance and making it susceptible to soil accumulation.
• Install remote mounted control enclosure outside of heat zone. Locating control enclosure inside heat zone will cause control(s) to overheat, malfunction, and fail.
• Do not slide pans across hardcoat surface, use rough-bottomed pans, or drop anything on hardcoat surface. Scratching may occur. Damage to hardcoat surface caused by misuse is not covered under warranty.
• Do not locate unit in area with excessive air movement around unit. Avoid areas that may be subject to active air movements or currents (i.e., near exhaust fans/hoods, air conditioning ducts, and exterior doors).

General

Use the following procedures to install the GRS, GRSB, and GRSBF units.

WARNING

FIRE HAZARD: Locate unit a minimum of 1″ (25 mm) from combustible walls and materials. If safe distances are not maintained, discoloration or combustion could occur.

CAUTION

• Locate unit at proper counter height in an area that is convenient for use. The location should be level to prevent unit or its contents from falling accidentally and strong enough to support the weight of unit and contents.
• Do not operate built-in models without control box mounted properly as described in the installation instructions.
• Do not operate unit without installing supplied legs.
• The National Sanitation Foundation (NSF) requires that units over 36″ (914 mm) in width or weighing more than 80 lbs. (36 kg) either be sealed to or raised above the installation surface. If unit cannot be sealed at the point of use, 4″ (102 mm) legs are included to allow for proper cleaning access below unit.

NOTICE

Do not operate unit prior to installing legs. Damage to unit could occur.

GRS Models

1. Remove the unit from the carton and place it upside down on the cardboard.
   NOTE: To prevent delay in obtaining warranty coverage, complete online warranty registration. See the
   I MPORTANT OWNER INFORMATION section for details.

2. Install the 1″ (25 mm) legs to the unit.

   • Thread a foot stud into the hole at each corner on the bottom of the unit. Tighten securely, but do not overtighten.
   • Slip a rubber foot over each foot stud.
     NOTE: If 4″ (102 mm) legs are required, refer to the OPTIONS AND ACCESSORIES section in this manual for installation instructions.
     NOTE : If the unit will be installed on a wire shelf, refer to the OPTIONS AND ACCESSORIES section in this manual for installation instructions.

3. Turn unit upright, and place unit in the desired location.

   • Locate the unit in an area where the ambient air temperature is constant and a minimum of 70° F (21° C). Avoid areas that may be subject to active air movements or currents (i.e., near exterior doors, exhaust fans/hoods, air conditioning ducts, etc…).
   • Make sure the unit is at the proper counter height in an area convenient for use.
   • Make sure the countertop is level and strong enough to support the weight of the unit and food product.
   • Make sure all the feet on the bottom of the unit are positioned securely on the countertop.

INSTALLATION

GRSB and GRSBF Models

1. Remove the unit from the carton and place it upside down on the cardboard.
   NOTE: To prevent delay in obtaining warranty coverage, complete online warranty registration. See the IMPORTANT OWNER INFORMATION section for details .

2. Remove and save the bracket screws from the underside of the unit.
   NOTE: The control box may be moved to the most convenient  location on the underside of the unit. For semi-remote installations, leave the control box in place until the unit is placed into the countertop.
   NOTICE: Unit is designed and recommended for use in or on metallic countertops. Damage to any countertop material is not covered under the Hatco warranty. For other surfaces, verify with manufacturer that material is suitable for prolonged temperatures up to 200°F (93°C).

3. Prepare countertop opening. Refer to the appropriate “Countertop Cutout” chart on the following pages for recommended countertop cutout dimensions.

4. Apply a bead of NSF-approved sealant between the countertop material and the mounting flange on the unit. The sealant must be rated for use at a minimum temperature of 250°F (121°C).

5. Place the unit into the countertop opening.

6. Assemble the Z-brackets to the underside of the unit using the four bracket screws removed earlier in this procedure (refer to the illustrations on the following pages).
   NOTE: Units 60″ (1524 mm) or longer require two additional Z-brackets to be installed midway along the front and rear of the unit.

7. Adjust the mounting screws on the Z-brackets until the top flange lies flat on the countertop.
   NOTICE: Do not use excessive force when tightening mounting screws on built-in units. This may damage unit and/or countertop.

8. Remove any excess sealant.

9. If desired or necessary, the control box can be mounted in a semi-remote location.

   • Remove the control box from the bottom of the unit.
   • If necessary, remove the end brackets from the control box, rotate/reposition, and re-secure to the control box.
   • The control box can be panel, surface, under counter, or recess mounted.
   • The distance the control box can be mounted from the unit is determined by the 36″ (914 mm) conduit. Do not pull the conduit tight to increase the mounting distance. The conduit should have some slack after the control box is mounted.
     NOTICE: Do not modify wiring or cut thermostat capillary on control enclosure to increase-remote mounting distance. Cutting thermostat capillary will cause unit to overheat and may damage unit as well as surrounding countertop.

10. Once all components are secured, proceed to the OPERATION section.
    NOTE: A 6′ (1829 mm) cord is supplied with this unit; any excess cord should be routed neatly so it does not hang down.
