Safety instructions

Please read these operating and maintenance instructions through carefully and also pass them on to other

people who are entrusted with handling and using this cabinet. Check the cabinet for transport damage immediately after delivery.

The cabinet may only be used in the position in which it is to be operated (level, horizontal with the opening to the

top). (Please observe the instructions for set up.)

The cabinet is used for the storage of foods that have already been chilled or frozen. Therefore any other use is

not considered as use as intended. Freezers may only be operated with the lid on.

The cabinet starts to work as soon as the operating voltage is switched on. Observe the ratings on the rating plate

and the relevant local regulations for electrical safety before you connect the cabinet to the power supply.

In all effective refrigeration condensation water is precipitated or the moisture held in the air is frozen onto

refrigerated surfaces. The operator must therefore defrost the cabinet regularly.

Do not heat the cabinet over 70°C (158°F). Do not expose the cabinet to direct sunlight and do not use any

heaters or sharp objects when defrosting. Do not spray high pressure cleaners or steam jet cleaners into the

machine space. Sharp objects can scratch and as a consequence break the glass lid (single pane safety glass).

Work on the electrical system and the refrigeration system may only be undertaken by qualified engineers. Before

unscrewing the machine space cover, the mains plug must be disconnected.

ATTENTION: Cabinets with interior lights have 2 mains cables. Before working on the electrical installation and

the refrigeration system, both mains plugs must be disconnected.

In order to maintain good food quality, it is recommended that frozen foods are only put into the freezers in the

period from 8:00 to 20:00

When disposing of the cabinet, please check your obligations according to the national WEEE regulations and take

the cabinet to the local WEEE disposal service. Please ensure that the pipes are not damaged (do not drill into the

cabinet). The operating staff must be instructed by the market manager.

People (including children) who are not able to use this unit safely because of their physical, sensory or mental faculties, inexpe-

rience or lack of knowledge should only do so under the supervision or instructions of an accountable person. Children in particular

should be supervised to ensure that they do not play with the unit. 12 No canisters containing ammable gas propellants may be stored in the unit. No objects such as bottles etc. may be placed on top of the cooler. The unit must be regularly inspected and foreign bodies removed from the goods display area.

Only thin film advertising stickers can be used. Do not fix thick, insulating materials on the outer walls. Avoid draughts and greater heat absorption at the installation site. Do not place cabinets in front of heaters and under air outlets. Do not point spotlights into the cabinets. Avoid lighting with light bulbs as much as possible. Fluorescent lights give off less heat!

Any heat radiation into the storage cabinet leads to increased operating costs and can influence the

cabinet's performance. ATTENTION: Do not expose cabinet to direct sunlight. The cabinet must not be heated over 70°C (158°F).

6 Connecting to the electrical supply

The cabinet is a plug-in compact cabinet.

The power cable (white) is 175 m. long. With cabinets with an internal light the lighting cable (black or light grey, depending on the country) is 120 cm. long. Both cables are located at the back right of the cabinet and are marked when they are delivered (mains cable - lighting cable). Protect with 16 A (surge-proof) fuse. (See technical data on the rating plate.) The supply cable should have a minimum cross- section of 2.5 mm 2 . 3-pole cables MUST be used. 5- pole cables must not be used. The use of extension cables or multiway adaptors should be avoided if possible. If this is unavoidable, make sure that the cables you use have a minimum cross-section of 2.5 mm 2 Cabinets should only be connected to shockproof sockets with earth contact and their own mains circuit. No more than

2 cabinets should ever be connected to a circuit.

With cabinets with additional flex for interior lighting only a maximum of 8 light flexes may be connected to a fuse. AHT recommends using a cable channel on the floor with sockets built into it or on top. The cable channel used must not be any higher than from the floor to the lower edge of the rear ventilation grid of the cabinet. Any other fixtures or superstructures (e.g. shelves with longitudinal supports above) that obstruct the dissipation of heat between the cabinets must be avoided. Should fittings between the cabinets be necessary anyway, written approval must be obtained from AHT for the relevant design. The sensor connection on the back of the cabinet must only be connected to a safety extra low voltage connection (SELV).

ATTENTION: Mains voltage and mains frequency

must match the ratings given on the cabinet's rating plate. Work on electrical systems may only be undertaken by qualified electricians. The relevant local safety regulations must be observed.

6.1 Internal lighting

Lighting is already incorporated into the cabinets with AHT cabinets with an internal light. An additional light socket must be available for each chest. No more than 8 internal lights may be connected to one electrical circuit. This information must be taken as a suggestion. The electrical supply company regulations and VDE regulations for the relevant region must be noted and observed. Electrical work must only be carried out by a qualified professional. When using light fixtures these may sometimes be connected to each other using the sockets that are already integrated. In this case you will normally only need 1 - 2 additional sockets for the lighting. With the LAK model no more than 12 light fittings can be connected to 1 fuse, with the LAL model no more than 18 light fittings and with the LA-A model no more than 8 light fittings. No other consumer loads may be connected to these sockets.

ATTENTION: You must ensure that no AHT cabinets

are connected to the lighting circuit. The connection cable for the lighting is marked with a sticker and is either black or grey (depending on the country). It is very sensible to mark the light sockets clearly to prevent them being confused with the cabinet connector plug (light grey cable). Otherwise there is the risk that the cabinets will be switched off when the supermarket lights are switched off.

6.2 Power supply details

An FI circuit breaker is provided to install AHT cabinets in the supermarket when the electrical installation is done. No more than 2 cabinets must be connected to a safety device like this. One safety device for each cabinet is preferable. 2 cabinets can be supplied for each safety device with a combination of a fuse and circuit breaker (LS/ FI circuit breaker).

AHT strongly recommends using an LS/FI

combination with C characteristic, 10A rated current and 30mA release current, type G surge protection for each cabinet. Should this suggestion not be acceptable, the following maximum specifications must be used: Fuse

A safety fuse with a

16A fuse with C characteristic

must be provided for AHT cabinets.

No more than 2 cabinets are permitted on 1 fuse.

However, in order to achieve the highest possible operational safety, we suggest that each chest has its own fuse.

FI circuit breakers

It is strongly recommended that you use FI circuit breakers. You must ensure that the type G circuit breaker used is be surge-protected. We suggest that the circuit breaker has the following capacity:

ATTENTION:

If the mains cable or light ex

15 A) characteristic C fuse is to be provided.

Rated current Release current

40A 30mA no more than 2 cabinets to 1 FI

A separate safety fuse is appropriate for the lighting for

AHT cabinets.

Load dropping switches or cabinet cut off switches are not permitted because malfunctions could occur as a result. Should these safety guidelines not be observed claims under the guarantee and/or for damages will not be entertained.

7 Using the cabinet for the first time

and function Before being used for the first time (after installation - see section 5) the cabinet should have a minimum temperature of +16°C (60.8°F), otherwise the cabinet must be adjusted to normal room temperature.

ATTENTION: When the operating voltage is switched

on (plug in mains plug - see section 6) the cooling unit starts to work straightaway. After operating for roughly 1 to 2 hours the desired interior temperature is reached (see section 9 - Recommended storage temperatures). The pre-chilled chilled food can be put in.

ATTENTION: Do not stand on or put

loads on the glass lid. The glass lids are not intended as aids for reachingquotesdbs_dbs12.pdfusesText_18
