IMPORTANT SAFETY INFORMATION  
IMPORTANT! Read the following important safety information to avoid personal injury  
or death, and to avoid damage to the equipment or property.  
WARNINGS  
To avoid any injury or damage all electrical  
connections must be in accordance with  
local electrical codes and any other  
applicable codes. Connections should be  
made by a qualified, licensed electrician.  
Only light bulbs which meet or exceed NSF  
standards, specifically designed for food  
holding areas may be used. Breakage of light  
bulbs not specially coated could result in  
personal injury and/or food contamination.  
To avoid any injury or damage to the strip  
heater turn the power OFF at the disconnect  
switch/circuit breaker and allow to cool  
before performing any maintenance.  
Units equipped with a cord and plug supplied  
by Hatco must be plugged into a properly  
grounded electrical outlet of the correct  
voltage, size and plug configuration. If the  
plug and receptacle do not match, contact a  
qualified electrician to determine the proper  
voltage and size and install the proper  
electrical outlet.  
If service is required on this unit, contact  
your Authorized Hatco Service Agent, or  
contact the Hatco Service Department at 800-  
558-0607 or 414-671-6350; fax 800-690-2966  
or International fax 414-671-3976.  
For safe and proper operation, the unit must  
be located the correct distance from  
combustible walls and materials. If safe  
distances are not maintained, discoloration  
or combustion could occur. Refer to specific  
installation and mounting information in this  
manual for proper clearances.  
This product has no “user” serviceable parts.  
To avoid damage to the unit or injury  
to personnel, use only Authorized Hatco  
Service Agents and Genuine Hatco  
Replacement Parts when service is required.  
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. It  
is essential to use Hatco Replacement Parts  
when repairing Hatco equipment. Failure to  
use Hatco Replacement Parts may subject  
operators of the equipment to hazardous  
electrical voltage, resulting in electrical  
shock or burn.  
To prevent any injury or damage to the unit  
do not store or use gasoline or other  
flammable vapors or liquids in the vicinity of  
this or any other appliance.  
The unit is not waterproof. DO NOT submerge  
in water. Do not operate if it has been  
submerged in water.  
To prevent combustion or damage to  
materials do not install standard wattage strip  
heater (GR, GRA, GRN, GRAL Series) less  
than 10" (254 mm) above a non-metallic  
surface. Do not install high wattage strip  
heater (GRH, GRAH, GRNH, GRAHL Series)  
less than 13-1/2" (343 mm) above a non-  
metallic surface. Do not install dual strip  
heaters (GRA-XXD, GRAH-XXD, GRAL-XXD &  
GRAHL-XXD Series) above non-metallic  
surface. Install all non-dual strip heaters so  
there is a minimum distance of 3" (76 mm)  
from a non-metallic wall or adjacent surface.  
To avoid any injury or damage to the unit  
when using chains for installation, the chains  
must have sufficient strength and be  
securely fastened, or the unit could become  
loose or fall. Do not place anything on top of  
warmers supported by chains.

IMPORTANT SAFETY INFORMATION  
CAUTIONS  
NOTICE  
Standard and approved manufacturing oils  
will smoke up to 30 minutes during initial  
start-up. This is a temporary condition. To  
assure safe operation, operate unit without  
food product until smoke dissipates.  
Use only non-abrasive cleaners. Abrasive  
cleaners could scratch the finish of your  
unit, marring its appearance and making it  
susceptible to dirt accumulation.  
To prevent premature failure to components  
the Remote Control Box (RMB) must be  
installed outside the strip heater heat zone.  
Some exterior surfaces on the unit will get  
hot. Use caution when touching these areas  
to avoid injury.  
Heat damage to countertop material such as  
Corian® and similar products (other than  
stainless steel) is not covered under the  
Hatco warranty. Contact the manufacturer of  
the base material for temperature limits and  
application information before installing the  
unit.  
To prevent unit failure do not add a  
decorative soffit to hide a pass-through  
mounted Glo-Ray Strip Heater.  
Strip Heaters with incandescent lights that  
require a circuit breaker larger than 20 amps  
must have a separate circuit breaker for the  
incandescent lights that is 20 amps or less.  
To assure safe and proper operation refer to  
Installation Clearance Requirements listed in  
this manual.  
Installation of two or more single units with  
less than 3" (76 mm) between housings may  
result in premature failure of component  
parts.  
Unit is not moisture proof. Spacing of at least  
16" (406 mm) is required for all units mounted  
over a steam table.

a non-metallic surface. Do not install dual strip  
heaters (GRA-XXD, GRAH-XXD, GRAL-XXD &  
GRAHL-XXD Series) above non-metallic surface.  
Install all non-dual strip heaters so there is a  
minimum distance of 3" (76 mm) from a non-  
metallic wall or adjacent surface.  
CAUTION  
Installation of two or more single units with less  
than 3" (76 mm) between housings may result in  
premature failure of component parts.
