NOTE

The termination klixon for gas defrost is located at the bypass check valve at the left end of the evaporator coil.

Most klixons are located on the right end of the evaporator coil. The diagram shows the location for each defrost type that uses a klixon.

CAUTION

If electronic sensors are used in place of the klixons, the sensors must be located in the same location as the klixons for that defrost type. Any other locations will effect the refrigeration efficiency of the case.

PROTECTION

120V circuits should be protected by 15 or 20 Amp devices per the requirements noted on the cabinet nameplate or the National Electrical Code, Canadian Electrical Code - Part 1, Section 28. 208V defrost circuits employ No. 12 AWG field wire leads for field connections. On remote cases intended for end to end line-ups, bonding for ground may rely upon the pull-up bolts.

The following wiring diagrams on pages 8 thru 11 will cover the NSSD case circuits including all defrost and lighting wiring circuits.
