temperatures rise above 45°F. This prema- turely discolors displayed meats and causes unnecessary meat department losses.
Radiant Heat Measurement
Place two accurate dial thermometers side by side in a case. Cover one of the thermometer stems with black friction tape. The tempera- ture difference is the approximate amount of radiant heat. A change in display lighting
or a reduction of high ceiling temperatures (over 80°F) could reduce the radiant heat in the case.
Display Practices
Encourage butchers to maintain all meat below the case load lines and to eliminate product voids. Case
screens could be covered in some instances to keep the refrigerated air over the display.
CAUTION
The quality damage done to meat products by high temperatures and/or contamination during delivery, cooler storage, cutting and wrapping cannot be repaired by placing the products into properly operating dis- play cases.

Ballast and Lighting Locations
All NSSD light ballasts are located either in the front raceway behind the lower front cladding, or in the rear raceway behind the rear rail cover. This includes remote ballasts for optional shelf lights. The canopy light(s) are under the canopy light channel in the top of the case. The optional shelf lights are mount- ed in separate light fixtures under the front of each shelf section.
In order to retain safety approval with Underwriters Laboratory and the Canadian Standards Association, the mounting of electrical components and interconnecting wires must not deviate from the following instructions. Only qualified personnel are authorized to install the accessory items. TYLER Refrigeration recommends you order all component parts from its Service Parts Department.
