Page 2: Manual Structure
Part I. Introduction, Installation, and Operation This is the I&O manual for the LD1C1A spot merchandiser and is part of the family of Kysor/Warren (KW) merchandisers. Its purpose is to assist the user in the installation and operation of these merchandisers.
Page 3 NOTE: Installation and service instructions for the condensing unit are not part of this manual. The LD1C1A-5 and LD1C1A-10 are installed individually in an area approximately 3-1/2 feet x 6 feet or 3-1/2 feet x 11 feet respectively. Adjustable glide feet are provided on each merchandiser for leveling the merchandiser. Swivel plate mount casters with brakes are optional in lieu of glide feet.
Page 4 Installation and Operation Manual 2.1. Components Electrical All field installed wiring must comply with the NATIONAL ELECTRICAL CODE AND LOCAL ELECTRICAL CODES. The merchandiser is provided with power cord(s) that have a male plug that is shipped loose for installation in the store. There is/are also matching female receptacle(s) that are shipped loose. To gain access to the inside of the electrical control panel, remove the control panel cover.

The defrost cycle is terminated either by a temperature sensor connected to the electronic controller or failsafe time returning the merchandiser into refrigeration mode. A defrost heater safety limit thermostat (Klixon) is wired in series with the defrost heater that opens if the temperature exceeds 70°F.

Installation and Operation Manual CAUTIONS: DO NOT FLUSH THE MERCHANDISER WITH WATER. This merchandiser is not connected to a drain system and has a defrost water evaporating pan with only a limited volume capacity. The merchandiser should have at least 18” clearance from any wall or other obstruction in order to operate properly. NOTE: Do not stack anything in front of the intake or exhaust louvers that may block airflow on the merchandiser.
Page 9 Self-Contained Spot Merchandiser Installation of Power Cord to Exit the Base-End Panel of the Merchandiser Install the cordgrip into the hole in the base end panel of the merchandiser. Route the power cord through the cordgrip installed in the base end panel and into the control panel through the hole located in the bottom right hand side of the control panel. Do not tighten the cordgrip until the power cord wire conductors have been connected into the circuit breaker and terminal board.
