Electrical Fuse Protection; Start-Up; Operation - AHT CB 196 Manuel D'utilisation

AHT Cooling Systems GmbH
• Material and property damage through deviations not
approved by AHT (voltage, direction or rotation, frequen-
cy) in the electrical grid of the operator.
► The manufacturer is not liable for damage to the
electrical equipment of the operator and consequential
damage caused by it.
• Material damage from incorrect electrical connection.
► Observe the correct direction of rotation (right rotating
field) of the voltage supply.
► Low voltage disconnects or appliance disconnections
are not permissible.

7.2. Electrical fuse protection

Each unit must be equipped with electrical fuse protection.
Technical data (see → Chapter 2.2).
Incorrect/inadequate electrical fuse protection.
Contact with live parts can lead to an electric
shock. Danger of fire from sparking or overloading.
► Ensure sufficient fuse protection.
► Never connect more than 1 unit to a circuit bre-
aker or alternatively a RCBO.
One of the following electrical fuse protections must be
used:
- Circuit breaker (MCB) in combination with a RCCB.
- Residual Circuit Breaker with Overload Protection
(RCBO)
Observe the respective applicable standards such as:
- VDE0100-410

8. Start-up

The unit may only be put into operation in the installation
room designated for that purpose and after checking for
completeness.
Damage to the electrical system and/or refrigerant
circuit.
Contact with live parts can lead to an electric
shock. Refrigerant can escape and cause an ex-
plosive gas/air mix. Danger of fire from sparking or
overloading.
► Do not put a damaged unit into operation.
► Do not connect damaged parts (such as power
cords) to the electric circuit.
► Damaged parts (like power cords) may only be
replaced by qualified specialists.
► Observe specific safety and warning information
for units with combustible refrigerants (see →
Chapter 1.6.2.1).
► Contact the maintenance service (see → Chap-
ter 10.4).
• Property damage from incorrect ambient conditions
► Adapt the unit to the ambient temperature before
starting it up.
► The ambient temperature must not be below 16°C.
Plug in both power plugs (unit connection and light/night
roller blind controller). After plugging in the power plug for
the unit connection, the refrigeration unit will start working
after a short delay of ca. 30 seconds.

9. Operation

Only trained operating personnel may operate the unit.
Damage to the electrical system and/or refrigerant
circuit during operation. Contact with live parts can
lead to an electric shock. Refrigerant can escape
and cause an explosive gas/air mix. Danger of fire
from sparking or overloading.
► 1. Disconnect the unit.
2. Secure the unit against being switched back on.
► Observe specific safety and warning information
for units with combustible refrigerants
(see → Chapter 1.6.2.1).
► Contact the maintenance service
(see → Chapter 10.4).
Breakage of stored glass containers. Cuts to the
hands and body.
► Use protective gloves to remove the splintered
glass and any products that may have been
damaged as a result.
► Carefully remove all glass splinters.
Leaking of liquids from damaged packaging.
Slipping hazard.
► Check for puddles forming in front of and under
the unit.
► Immediately remove any leaking liquids.
NOTICE
• Material damage from improper use!.
► Operate the unit in its position of use and in a stable
position (aligned horizontally).
► Only operate the unit on the adjustable feet provided
for that purpose.
► Check the unit regularly to make sure it is in perfect
condition. Damage must be repaired immediately.
• Property damage from improper use.
► Do not operate the unit above the climate class speci-
fied on the rating plate or alternatively on the supple-
mental stickers (see → Chapter 2.2.1 and 2.3).
► The ambient temperature must not be below 16°C.
► Check the inside temperature (see → Chapter 4.1).
► Stored products must be checked by the operator in
the event of a power cut (temperature check).
► Regularly check for foreign objects in the product
compartment. Improperly stored products must be
removed immediately.
► Remove food residue such as, for example, liquids and
packaging material residue (see → Chapter 10.1.1).
For special climatic conditions with high air humidity, con-
densate (defrosting water) may form on the interior of the
unit or on the air outlet openings on top. This condensate
should be removed for hygienic reasons.
