INTRODUCTION
Hatco Glo-Ray®Strip Heaters ensure maximum food
holding and minimize the risk of food-borne illness.
Optimum safety and quality is the result of food held
at the proper serving temperatures, using Glo-Ray’s
pre-focused heat patterns. The pre-focused heat
pattern prevents foods frombeing over-cooked in the
middle and cooling off around the edges by
concentratinghighertemperaturesto the outer edges
of holding surfaces where heat loss is the greatest.
Utilizing specially designed reflectors to direct the
heat from the element, Glo-Ray Strip Heaters safely
maintain peak serving temperatures longer without
cooking the food beyond the point of excellence.
Glo-Ray Strip Heaters are available from the factory
withor without shatter-resistantincandescentlightsto
illuminate the warming area. These bulbs have a
special coating that guards against injury and food
contamination in the event of breakage.
Glo-Ray Strip Heaters are a product of extensive
research and field testing. The materials used were
selectedformaximumdurability,attractive
appearance,and optimumperformance.Every unit is
inspected and tested thoroughly prior to shipment.
Additional information can be found by visiting our
web site at www.hatcocorp.com.

overhead surface with the use of “S” hooks. “S”
hook mounted units are available in 120V only and
are required to have a power cord and plug
connection.
NOTE: Unitsordered with the “S” hook option come
with two “S” hooks and two 6″ (152 mm)
pieces of connecting chain. Additional chain
(P/N 05.03.020.00) can be ordered from
Hatco for the overhead mounting system or
another option can be determined by a
qualified installer.
INSTALLATION
Figure 25. “S” Hook Mounting
For installation with chains, make sure the
chains have sufficient strength and are securely
fastened to both the unit and the mounting
location. Poorly installed chains may cause the
unit to loosen and fall. Do not place anything on
top of units installed with chains.
To ensure safe and proper operation, refer to the
Clearance Requirements listed in the Installation
section of this manual.
NOTE: The strength of the chain supplied by Hatco
is sufficient to hold the weight of the unit
securely only when mounted properly.
1. Prepare the overhead mounting system for the
“S” hooks. Make sure the system is secure and
is set up so the unit will be suspended at a level,
safe, and proper distance from walls, counter,
and food.
2. Loosen, but do not remove the screws securing
the hanger tabs on each end of the unit. Rotate
the tabs up, then tighten the screws securely.
3. Securely attach one of the 6″ (152 mm)
connecting chains between each pair of hanger
tabs.
4. Attach an “S” hook to the center of each
connecting chain.
5. Carefully lift the unit and attach the “S” hooks on
each end of the unit to the overhead mounting
system. Make sure the unit is level.
Sneeze Guard Installation (optional)
1. Remove the protective paper from the acrylic
surfaces.
2. Assemble each weld screw through the top of
the sneeze guard and through the support bar.
Loosely thread an acorn nut onto each of the
weld screws below the support bar.
3. Lift the sneeze guard assembly and carefully
slide each of the weld screws that are loosely
attached to the sneeze guard into the channel
on the unit (see Figure 27).
4. Align each end of the sneeze guard with the
ends of the unit and then tighten the acorn nuts
to secure the sneeze guard in position. Do not
over-tighten the acorn nuts.
