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 as well and lift the unit off the skid. If the unit is on casters it can be "rolled" off the skid.

ASM Series Service and Installation Manual

Installation

Location

Unit is designed to maintain 36°F - 40°F (2°C - 4°C) at 80°F (27°C) ambient room temperature in 55% or lower relative humidity.

Units represented in this manual are for indoor use only. Be sure the location chosen has a counter strong enough to support the total weight of the cabinet and contents. A fully loaded model may weigh as much as 1,500 pounds! Reinforce the counter as necessary to provide for maximum loading.

These units are installed by placing them into the counter from above. The counter cutout sizes are as follows:

36" Units - 35.13" x 25.50" (89cm x 65cm)

48" Units - 47.13" x 25.50" (120cm x 65cm)

60" Units - 59.13" x 25.50" (150cm x 65cm)

Two louvers are provided with each

Discharge Air

unit and must be installed in 17.00"

Louver

x 28.00" (43cm x 71cm) cutouts.

Cut-outs are to begin at 10.00"

(25cm) from the counter-top.

For the most efficient refrigeration,

be sure to provide good air

circulation inside and out. Don’t pack

the merchandiser so full that

cannot circulate. Avoid hot corners

Fresh Air In On

and locations near stoves and ovens.

Customer Side

Air movement in the room will adversely effect ASM refrigeration. Do not place the model near doors or air vents.

It is recommended that the unit be installed no closer than 1” from any wall. Do not install the unit near any combustible material or object affected by heat or moisture.

Failure to provide the proper air flow will void the warranty.

Plumbing

Standard models will have a 1/2" drain which will need to be run to an appropriate floor drain. The drain will be stubbed inside the machine compartment. All units have an optional electric condensate evaporator. If 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

CAUTION

provide a container or outlet for drainage.

Electrical connection

Refer to the amperage data on page 3, 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.

An ON/OFF switch is located on the remote control panel. Simply turn the switch to ON to begin operation. There is a second ON/ OFF switch on the remote control panel for the lights.

The power switch should be turned to OFF and the unit disconnected from the power source whenever performing service or maintenance functions.

ASM Series Service and Installation Manual

Operation

Located on the Remote Control Panel are two ON/OFF switches. One will turn ON/OFF the unit’s compressor. The lights are controlled by the other switch.

Delfield's Air Screen Merchandisers are designed to maintain an operational temperature of 36°F - 40°F (2°C - 4°C) at 80°F (27°C) ambient room temperature in 55% or lower relative humidity. Overloading the merchandiser, restricting the air flow, and continuous opening and closing of the doors will hinder the unit’s ability to maintain operational temperatures.

If humidity is above 55%, condensation on the glass will be present.

Proper airflow is critical to maintaining temperature. Do not interfere with the airflow by placing product over the air return openings. The Air Diffuser Pan Assembly must be properly in place at the bottom of the merchandising case, with the air return openings on the customer side. After cleaning or servicing the Front Deflector Glass, Honeycomb Diffuser and Airduct Plexiglas Panel must be replaced properly.

Sliding Door Removal And Reinstall

Sliding Door Removal

Open the door almost completely. Firmly grasp both sides of the door. Lift the door up and move it until it enters a notch and can be lifted higher. Tilt the bottom out without removing the top. Use the top to gently return the spring to the closed position. Remove the door from the top track.

Sliding Door Reinstall

There is a notch in the top inside corner of the door. Put the spring in the door's notch and move the spring to the open position. Put the top into the track and find the notch where the door can be lifted higher. Set bottom of the door into the track.

Night & Security Cover Operations

At the factory, the keys are taped to the display case. Pull the cover down, turn the key 90° to lock.
