Installation & Service Manual

TLM, TLF, TLD

c.Push the Up or Down Button until the desired setpoint is displayed. (TLM = 22°F, TLF = 33°F or TLD = 22°F)

d.Push the Menu Button.

8.To adjust the differential:

a.Push the Menu Button. “SP” will flash on the LCD display.

b.Push the Down Button until “DIF” is shown on the LCD display.

c.Push the Menu Button one more time and a differential number will be displayed.

d.Push the Up or Down Button until the desired differential setting is

displayed. (TLM = 4°F, TLF = 1°F or TLD = 4°F)

d. Push the Menu Button.

With the cooling mode selected, the differential is ABOVE the setpoint. The relay will be energized and the LED indicator will illuminate when the temperature reaches the differential setting. When the temperature drops to the setpoint, the relay and LED indicator will de-energize and refrigeration will stop.

The settings above are specific to TYLER service cases. Other applications will require different setpoints and differentials.

Electrical Procedures

Electrical Considerations

CAUTION

Make sure all electrical connections at components and terminal blocks are tight. This prevents burning of electrical termi- nals and/or premature component failure.

NOTE

The ballast box is located at the lower left rear corner of the case. It houses ballasts and terminal blocks.

Case Fan Circuit (TLD only)

This circuit is to be supplied by an uninterrupted, protected 120V circuit. The case fan circuit is not cycled on this case.

Ambient Fan Circuit

All TL cases have an ambient fan circuit. This circuit is supplied by an uninterrupted, protect- ed 120V circuit. The ambient fan circuit is not cycled.

Fluorescent Lamp Circuit

TL case lighting is supplied by T-8 electronic ballast lights. It is controlled by a light switch in each case. The standard lighting is 1-row of horizontal canopy lights.

Anti-Sweat Circuit

All anti-sweat heaters are wired directly to the main power supply so they can operate at all times.

Defrost Information

See “General (UL/NSF) I&S Manual” for operational descriptions for each type of defrosy control.

ELECTRICIAN NOTE - OVERCURRENT

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 wiring diagrams on pages 14 thru 21 will cover all TLM, TLF and TLD case circuits.
