7. Operating description

7.1. Load Display Case

Load the display case with pre-chilled product from the rear doors. You can place the goods on the

glass shelves and on the base decks. VIENNA Air Screen models have a deep well with height

adjustable base decks.

You can also use different Gastronorm containers with a choice of additionally divisional bars. This

offers you a wide range of ways to display your merchandise. Beverages, trays and GN containers

can be placed side by side in one refrigerated display case at same time!

The display case is designed to maintain the temperature of pre-chilled product.

This refrigerated unit is not a refrigerator, and consequently, if warm product is introduced,

there could be a considerable delay before the operating temperature falls to the normal

operating level.

7.2. Loading Restrictions

 It is important to leave adequate free space for the refrigerated air to circulate within the display

case.

 Products should be kept clear of the shaded areas, shown in the picture.

 A minimum clearance of 1 ½” should be maintained below the light fittings and air plenums.

 The air openings at the front and rear of the display case must never be blocked.

The presented goods are refrigerated with

cold air.

This air curtain is forced by fans which suck

the air via air louvers at the front (1) into the

Evaporator (2).

In this area below the base decks the air is

chilled and blown up through the air

plenums at the rear (3) into the display

case.

All these components are designed to have

an even distribution of chilled air in the

whole display case to guarantee constant

temperature.

The VIAS and VICD Displays come with a

deep well and are equipped with base

decks, which are adjustable in height.

Additionally you can use different Hotel

pans. Therefore additionally adapter bars

are available.

This offers you a wide range of application

presenting your goods.

8.3. Special cleaning hints

Cleaning of the interior and evaporator coil

 Take out the GN containers or base decks (1) and air plenums (2) and inner tray from the well.

First of all remove visible dirt inside the well (bottom) to avoid a blockage of the drain (5 und 6).

Open the cover from the evaporator unit (3). Entire s/s housing and evaporator coil can be rinsed

safety and easily with a hand spray (4). Fans in low voltage (24V) allow danger-free cleaning. Lift

up the evaporator unit and move the lock to the left (5 und 6) – now the evaporator is fixed and

allows easy access for cleaning corners and floor of the well (7).

Picture 4 Picture 5 Picture 6 Picture 7

 ATTENTION: Before cleaning the unit with water please check that the water can run off. If the

unit isn’t plumped to a floor drain, place an external bin below the drain to collect the wastewater.

 The evaporator and the interior have to be cleaned with lukewarm soap water. Always dry the

interior after cleaning. After cleaning lift the evaporator, remove the lock and drop the evaporator

back in its original position.

 Insert the inner tray, position the air plenums with the hanging tracks and drop in the base decks

or GN containers.

 Never clean the outside of the refrigerated well with a water hose or an abrasive sponge. Avoid

flowing water near these areas.

 All other surfaces can be cleaned with soft detergents or water.

Cleaning of condenser unit

Each self-contained refrigeration unit requires periodic cleaning of the condenser unit.

The condenser coil (looks like a radiator and is directly in front of the fan) requires periodic cleaning.

A dirty condenser is the main cause of refrigeration overheating, burnout and poor cooling levels.

Similar to the daily merchandise area cleaning, it is necessary to remove the static dust build up from

the condenser coils to ensure effective and trouble free operation.

The condenser should be thoroughly cleaned monthly (under extreme conditions clean more often)!

Important: Warranty void if this service is neglected or temperature controls interfered with.
