SERIAL NUMBER LOCATION

On refrigeration, freezer and heated storage units, the serial tag is located inside the right most door (the only door on a one-door unit), near the top front corner of the right interior wall.

Always have the serial number of your unit available when calling for parts or service. A complete list of authorized Delfield parts depots is shown on the back cover of this manual.

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 view 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.

Meridian Series® Reach-Ins Service and Installation Manual

INSTALLATION REACH-INS AND PASS THROUGHS

Location

Units represented in this manual 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. Allow for a total load of approximately 600 pounds (273kg) per door section. Reinforce the floor if necessary to provide for maximum loading. For the most efficient operation, be sure to provide good air circulation inside and out.

Inside cabinet: Take care not to block air flow to the fans or heating elements and allow space along the front, back and sides.

Outside cabinet: Be sure that the unit has access to ample air; avoid hot corners and locations near stoves and ovens. Always provide a minimum of 12” (30.5 cm) of clearance above the unit that is open to the front.

If the doors need to be removed during installation, remove the door by lifting it up and easing it out of the hinge brackets.

Leveling

A level cabinet looks better and will perform better because the doors will line up with the door frames properly, and the cabinet will not be subject to unnecessary strain.

Stabilizing

It is very important that all legs are properly adjusted to keep the unit level, evenly distribute the weight and to make sure the unit will not rock, lean or be unstable.

Electrical connection

Refer to the amperage data on pages 3-7 or the serial tag data and 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 supply cord or permanent connection to the unit. The power must be turned off and disconnected whenever performing maintenance or repair functions.

Permanently connected units must be connected in accordance with NEC Article 422 Appliances. C-Disconnecting means. It is the responsibility of the end user to provide the disconnect means to satisfy the authority having jurisdiction.

Large cabinets should always be moved with extreme care and caution.
