---

What is the startup procedure for all models?

1. Plug the unit into a properly grounded electrical receptacle of the correct voltage, size, and plug configuration. See the SPECIFICATIONS section for details.

---

How do I start up GRCD and GRHD (Non-Humidified) Models?

1. Move the Power I/O (on/off) switch on the base to the I (on) position.
2. Turn the BASE HEAT CONTROL to the desired temperature setting.
3. Turn the TOP HEAT CONTROL and the CENTER HEAT CONTROL (dual units only) to the desired temperature setting.

On dual-shelf models, the TOP HEAT and CENTER HEAT indicator lights will illuminate when controls are in the “on” position.

---

What should I do after starting up the GRCD and GRHD models?

Allow the unit 30 minutes to reach operating temperature.

---

How do I start up GRCDH and GRHDH (Humidified) Models?

1. Remove the reservoir cover from the water reservoir (two covers on GRHDH-4P and -4PD models).
2. Fill the water reservoir with softened or distilled water. Each reservoir has a 2 quart (1.9 liter) capacity.
3. Move the Power I/O (on/off) switch to the I (on) position.
   • If the red Low Water indicator is on, press the red Reset Button located to the left of the indicator light.

The reservoir capacity permits uninterrupted operation for approximately 4 hours, depending on the settings and how frequently the door is opened. When the red LOW WATER indicator is lit, add water to the reservoir and press the red Reset Button.

4. Rotate the HUMIDITY CONTROL to the desired position.
   • The HUMIDITY ON Indicator (green) will light up to show that humidity is on. The LOW WATER indicator (red) will light when the water reservoir is empty.
   • The unit can be run without humidity by turning the HUMIDITY CONTROL to the O (off) position.
5. Re-install the reservoir cover.
6. Turn the BASE HEAT CONTROL to the desired temperature setting.
7. Turn the TOP HEAT CONTROL and the CENTER HEAT CONTROL (dual units only) to the desired temperature setting.

On dual shelf models, the TOP HEAT and CENTER HEAT indicator lights will illuminate when controls are in the ON position.

---

What should I do after starting up the GRCDH and GRHDH models?

Allow the unit 30 minutes to reach operating temperature.

---

What should I know about temperature and humidity settings?

Temperature and humidity settings may vary depending upon product make-up and consistency.

---

What is the shutdown procedure for all models?

1. Move the Power I/O (on/off) switch on the base to the O (off) position.

---

What is the general maintenance procedure?

Hatco® Glo-Ray Heated Display Cases are designed for maximum durability and performance, with minimum maintenance.

---

What are the safety precautions for maintenance?

• Turn OFF power switch, unplug power cord, and allow the unit to cool before performing any cleaning, adjustments, or maintenance.
• DO NOT submerge or saturate with water. The unit is not waterproof. Do not operate if the unit has been submerged or saturated with water.
• Do not steam clean or use excessive water on the unit.
• This unit is not “jet-proof” construction. Do not use jet-clean spray to clean this unit.
• This unit must be serviced by qualified personnel only. Service by unqualified personnel may lead to electric shock or burn.
• Do not clean the unit when it is energized or hot.
• 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.

---

What should I do if service is required on the unit?

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 414-671-6350.

---

What is the recommended procedure for daily cleaning?

To preserve the finish of the unit as well as maintain performance, it is recommended that the unit be cleaned daily. 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.

1. Turn off the unit, unplug the power cord, and allow the unit to cool.

2. Wipe down all exterior and interior surfaces. A non-abrasive cleaner may be used for difficult stains. Hard to reach areas should be cleaned using a small brush and mild soap.

   • Make sure to clean the interior of the unit thoroughly.
   • Rear doors can be removed by sliding each door to the center then lifting up and tilting out of the bottom channel.
   • Clean the glass front, side, and rear panels using ordinary glass cleaner and a damp, soft cloth or paper towel.

3. Empty and clean the water reservoir using a damp cloth (humidified units only).

4. Wipe dry the entire unit with a clean, non-abrasive cloth.

---

What are the instructions for removing lime and mineral deposits from humidified models?

Use the following procedure for periodic cleaning and deliming of the water reservoir on humidified models. Use of distilled water in the water reservoir of humidified units is recommended to preserve the life of electrical and mechanical components. If non-distilled water is used, the reservoir will require periodic cleaning and deliming. Unit failure due to lime or mineral deposits is not covered under warranty.

The lime and mineral content of the water used for daily operation will determine how often the deliming procedure must be performed.

Perform this procedure when the unit will not be used for a period of time, such as the end of the day.

1. Move the Power I/O (on/off) switch to the O (off) position and unplug the power cord. Allow the unit to cool.
2. Remove the water reservoir cover and water reservoir. Empty the water reservoir.
3. Reinstall the water reservoir.
4. Fill the water reservoir with a mixture of 75% water and 25% white vinegar. Do not use flavored vinegar.
5. Plug in and turn on the unit. Allow the unit to run for 30 minutes.
6. Move the Power I/O (on/off) switch to the O (off) position and unplug the power cord. Allow the unit to cool.
7. Empty the deliming mixture from the water reservoir.
8. Continue to fill and rinse the water reservoir with clean water until the reservoir is clean.
9. Install the water reservoir into the unit and fill the reservoir as usual for daily operation.
10. Install the water reservoir cover.

What type of light bulbs should I use for replacement?

Use only light bulbs that meet or exceed NSF standards and are specifically designed for food holding areas.

---

What should I do if a light bulb breaks?

Breakage of light bulbs not specially coated could result in personal injury and/or food contamination.

---

What is the procedure for replacing display light bulbs?

The display lights are incandescent light bulbs that illuminate the warming area. Each bulb has a special coating to guard against injury and food contamination in the event of breakage.

1. Turn off the unit, unplug the power cord, and allow the unit to cool.
2. Unscrew the light bulb from the unit and replace it with a new, specially-coated incandescent light bulb.

Hatco shatter-resistant light bulbs meet NSF standards for food holding and display areas. For 120, 120/208, and 120/240 V applications, use Hatco P/N 02.30.265.00. For 220 or 240 V applications, use Hatco P/N 02.30.266.00.
