CASES MOVE ON CASTERS FOR EASIER INSTALLATION KATS cases are manufactured and shipped to stores with casters installed on the base frame to make the job of moving cases easier for everyone involved with the manufacturing, shipping and installation process. Casters not only speed up the process, but they also reduce the chance of damage from raising and lowering cases with ”J” bar to place them on dollies, skates or rollers. In most situations, one or two persons can move the case with ease.
LINE UP & TRIM OUT Now that cases have been positioned and leveled, you may proceed to trim-out case lineup. Trim parts have been designed to be applied easily with only a small number of fasteners required. Most external parts are adjustable to achieve almost invisible, snug-fitting joints and a high level of excellence in fit and finish.

4 5 CAULK CAULK 3 2 Remove Shipping Accessories From Case. Add Sealant. Remove anything from case that may interfere with case joining (eg. shipping braces). Run a bead of sealant around entire end before pushing cases tightly together. 8 1 Bolt Cases Together Using Bolt Holes Provided Push cases tightly together. Bolt cases together through the four holes provided. Tighten until all margins are equal; do not over tighten. 9 Add Sealant to Top Case Joint.
REFRIGERATION PIPING The expansion valve and other controls are located just under the top access hatch. Pull open the hatch and lift off the end evaporator cover on the left hand side to access the refrigeration controls. Refrigeration components and the coil outlet hole are located to provide the best access for installation and maintenance. As the diagrams below indicates, the coil outlet hole is positioned on top of the case on the rear, right hand side.
PLUMBING The kickplate is shipped loose with the case for field installation, therefore you should have open access to the drain line area. If the kickplate has been installed, you will find it very easy to remove. See instructions below, or the line-up and trim out section of this manual on page 7. The drain outlet is located front and center of the cases for convenient access. The drain outlet on the KRZH is molded out of ABS material.
ELECTRICAL HOOKUP Electrical hookups are made to a junction box located at the top, left of the case. For case-to-case wiring, run “greenfield”, or other conduit, between junction boxes. When connecting to the junction box on the bottom left side of the case, field wiring should exit the junction box from the right hand side, furthest away from case wiring, increasing room inside for wire connecting. 20 3/4 in [52.7 cm] ** 34 1/4 in [87.0 cm] 44 5/8 in [113.3 cm] 42 7/16 in [107.

DEFROST AND TEMP CONTROL This case is equipped with either Electric or Hot Gas defrost at the owners option. The sensor bulb and probe for electric defrost termination control is located on the top, center of the coil at the rear. The sensor bulb for temperature control is located on the right side of the evaporator behind the end cover, as shown in illustration 1 below. The discharge air probe is located behind a 3 1/2” plug button on the top flue panel also shown in illustration 1.
AIR FLOW AND PRODUCT LOADING Cases have been designed to provide maximum product capacity within the refrigerated air envelope. It is important that you do not overload the food product display so that it impinges on the air flow pattern. Overloading will cause malfunction and the loss of proper temperature levels, particularly when discharge and return air sections are covered. Please keep products within the load limit line shown on the diagram. DISCHARGE..............1 LOAD LIMIT...............
USE AND MAINTENANCE CASE CLEANING Case is designed to facilitate cleaning. There is no mechanical or electrical controls in the product area to hamper routine cleaning. All surfaces pitch to a deepdrawn drain trough that angles toward the front and center of case where the 2” waste outlet is located for easy access. The coil and fan plenum are located outside the product area to keep food fluids from entering, diminish downtime, and reduce shrink.
USE AND MAINTENANCE FANS 2 The evaporator fans are equipped with 25 watt fan motors, 1550 RPM’s, with a clockwise rotation when viewed from the shaft end. The fan blades are 8” in diameter and the blades are pitched to 31 degrees as indicated on the chart below. It is important that the blade pitch be maintained as specified. Do not attempt a field modification by altering the blades.
