Receiving And Inspecting The Equipment
Even though most equipment is shipped crated, care should be taken during unloading so the equipment is not damaged while being moved into the building.
1.Visually inspect the exterior of the package and skid or container. Any damage should be noted and reported to the delivering carrier immediately.
2.If damaged, open and inspect the contents with the carrier.
3.In the event that the exterior is not damaged, yet upon opening, there is concealed damage to the equipment notify the carrier. Notification should be made verbally as well as in written form.
4.Request an inspection by the shipping company of the damaged equipment. This should be done within 10 days from receipt of the equipment.
5.Check the lower portion of the unit to be sure legs or casters are not bent.
6.Also open the compressor compartment housing and visually inspect the refrigeration package. Be sure lines are secure and base is still intact.
7.Freight carriers can supply the necessary damage forms upon request.
8.Retain all crating material until an inspection has been made or waived.
Uncrating the Equipment
First cut and remove the banding from around the crate. Remove the front of the crate material, use of some tools will be required. If the unit is on legs remove the top of the crate and lift the unit off the skid. If the unit is on casters it can be "rolled" off the skid.

Installation
Location
These units are intended for indoor use only. Be sure the location chosen has a floor strong enough to support the total weight of the cabinet and contents. A fully loaded 72” long model may weigh as much as 1200 pounds. Reinforce the floor as necessary to provide for maximum loading.
For the most efficient refrigeration, be sure to provide good air circulation inside and out.
Inside cabinet: Do not pack refrigerator so full that air cannot circulate.
Outside cabinet: Be sure that the unit has access to ample air. Avoid hot corners and locations near stoves and ovens.
It is recommended that the unit be installed no closer than 1” from any wall. PDL models also require 14” (36cm) clearance at the top and 6” (15cm) clearance at the bottom (casters).
Leveling
A level cabinet looks better and will perform better because the drain pan will drain properly, the doors will line up with the frames properly, and the cabinet will not be subject to undue strain.
Some models have casters for your convenience, for ease of cleaning underneath and for mobility. It is important that the unit be installed in a stable condition with the front casters locked before operating.
Plumbing
Self-contained models are standard with a condensate evaporator. If, for some reason, a unit does not have a condensate evaporator, or the evaporator fails, the unit’s drain must have an outlet to an appropriate drainage area or container.
Moisture collecting from improper drainage can create a slippery surface on the floor and a hazard to employees. It is the owner’s responsibility to provide
CAUTION a container or outlet for drainage.
Electrical connection
Refer to the amperage data, the serial tag, your local code or the National Electrical Code to be sure the unit is connected to the proper power source. A protected circuit of the correct voltage and amperage must be run for connection of the line cord, or permanent connection to the unit.
The power switch must be turned to OFF and the unit disconnected from the power source whenever performing service or maintenance functions.

18600 and CTP-NB Series Service and Installation Manual
Operation: 18600PTBM & PTL Series
Product should be loaded into the unit with care. Failure to heed these recommendations could result in damage to the interior of the cabinet or the blower coil.
This unit is equipped with two on/off switches located behind the louvered machine compartment panel. The unit’s compressor and all evaporator fans will begin operating when the main power switch is turned to the ON position. Temperature ranges for the base are 36°F to 40°F.
The switch labeled rail is for the raised rail. The rail switch is accessible through a 1.5” diameter hole in the louvered panel. Turning this switch to the ON position will activate the refrigeration for the rail. Temperature ranges for the raised rail are 33°F to 41°F.
Product located in the rail must be removed at the end of day. This allows you to turn the rail off at night to save energy and the rail will have time to defrost as needed.
A minimum of one hour of off time per day with the pans removed from the rail is required to properly defrost the rail.
The power must be turned to OFF and the unit disconnected from the power source whenever performing service or maintenance functions.
Never operate the unit without the louvered panel in place!
All R404A models have a high pressure limiting device. Under severe overloading conditions, or in the event of a condenser fan failure or a plugged or blocked condenser, this device may shut down the refrigeration system. This device will automatically reset, but determining the cause of the high pressure condition should be investigated by a qualified refrigeration technician.
Refrigerator Evaporator Fan Operation
When the refrigerator is initially powered up or immediately following a power outage the unit will begin cooling after a 3-6 minute delay. During normal operation the evaporator fan pulses independently of the compressor as dictated by the controller as follows:
1.During the cooling mode, compressor and evaporator fan run simultaneously.
2.During the compressor off mode, evaporator fan pulses three minutes on and three minutes off.
3.During an actual defrost event other than the off-cycle defrost, compressor stays off but the evaporator fan runs continuously.

18600 and CTP-NB Series Service and Installation Manual
Operation: 18600PDL Series
Product should be loaded into the unit with care. Failure to heed these recommendations could result in damage to the interior of the cabinet or the blower coil.
This unit is equipped with two on/off switches located behind the louvered machine compartment panel. The unit’s compressor and all evaporator fans will begin operating when the main power switch is turned to the ON position. Temperature ranges for the base are 36°F to 40°F (2°C to 4°C).
The switch labeled rail is for the raised rails. The rail switch is accessible through a 1.5” (3.8cm) diameter hole in the louvered panel. Turning this switch to the ON position will activate the refrigeration for the rails. Temperature ranges for the raised rails are 33°F to 41°F (0.5°C to 5°C).
Product located in the rails must be removed at the end of day. This allows you to turn the rails off at night to save energy and the rails will have time to defrost as needed.
A minimum of one hour of off time per day with the pans removed from the rails is required to properly defrost the rails.
The power must be turned to OFF and the unit disconnected from the power source whenever performing service or maintenance functions.
