INSTALLATION PROCEDURES

Carpentry Procedures

Case Pull-Up Locations

The N5D, N5DH, N5DL and N5DSC models
have four pull-ups at each end of the case.
Pull-ups A, B, C and D are located as shown
and should be install-ed and tightened starting
with A and finishing with D.

See “General-UL/NSF I&S Manual” for line­up assembly instructions.

Electrical Procedures

Electrical Considerations

CA

UTION

Make sure all electrical connections at com­ponents and terminal blocks are tight.

NOTE

Since the lower front cladding is shipped
loose, the wiring has immediate access.

Case Fan Circuit

This circuit is to be supplied by an uninter­rupted, protected 120V circuit. The case fan
circuit is not cycled during defrost on any of
these models.

Fluorescent Lamp Circuit

N5D/N5DH/N5DL/N5DSC case lighting is
supplied by 800MA HO horizontal lights. It is
controlled by a light switch in each case. The
standard lighting is 1-row of high output
800MA canopy lights.
N5D/N5DH/N5DL/N5DSC also offers up to 4
rows of T-8 shelf lights with remote electronic
ballasts.

Self-Contained Circuit

LNDSC cases are self-contained units.
Information pertaining to self-contained units
should be obtained directly from TYLER
Refrigeration.

Defrost Information

See “General-UL/NSF I&S Manual” for
operational descriptions for Off Time
defrost control.

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 7
thru 12 will cover the N5D, N5DH, N5DL and
N5DSC case circuits and the lighting
circuits.
