Material damage
due to incorrect electrical connection.
▶ Pay attention to the correct direction of rotation (right
rotary fi eld) of the voltage supply.
▶ Load shedding circuits or device disconnections are
not permitted.
7.2 Electrical fuse protection
Each appliance must be equipped with electrical fuse pro-
tection. Technical specifi cations see
➙
Chapter 2.2.
WArNiNG
Incorrect/insuffi cient fuse protection.
contact with any parts carrying live volt-
age can cause an electric shock. risk of
fi re due to sparks or overload.
▶ Be sure there is suffi cient fuse protection.
▶ Never connect more than one appliance to a
miniature circuit breaker (MCB) or a residual
current circuit breaker with overprotection
(RCBO).
One of the following circuit breakers must be used:
∙
A miniature circuit breaker (MCB) in combination with a
remote control circuit breaker (RCCB).
∙
A residual current circuit breaker with overcurrent pro-
tection (RCBO).
Observe the relevant applicable standards, for example:
∙
VDE0100-410
∙
NEC 70
8. commissioning
The commissioning of the appliance / appliance group and
the external unit must be carried out by specialist personnel
in consultation with the operator. This work must be carried
out in accordance with the VENTO GREEN MC FREEZE
system commissioning manual. This manual is provided to
specialist personnel.
The appliance may only be put into operation at the
intended installation space after checking for completeness.
WArNiNG
Danger due to the spread of leaked refriger-
ant in sewage drainage. the accumulation
of refrigerant can cause an explosive gas/
air mixture. Risk of fi re.
▶ Before commissioning and re-commissioning,
fi ll the drain with approximately 2 litres of water.
WArNiNG
Damage to the electrical system and/or the
refrigerant circuit. contact with any parts
carrying live voltage can cause an electric
shock. refrigerant can escape and cause
an explosive gas/air mixture. Risk of fi re
due to sparks or overload.
▶
Do not put a damaged appliance into operation.
▶
Do not connect damaged parts (for example
damaged network connection cables) to the
electric circuit.
▶ Only specialist personnel are permitted to
replace damaged parts (for example, net-
work connection cables).
▶ Observe the safety instructions and warn-
ings for appliances with fl ammable refriger-
ants (see
➙
Chapter 1.6.2.1).
▶ Contact maintenance services (see
➙
Chapter 10.4).
NOTICE
∙
Property damage
due to incorrect ambient conditions.
▶
Adapt the appliance to the ambient temperature
before commissioning.
▶
Do not operate the appliance above the conditions
specifi ed in the climate class (ambient temperature,
relative air humidity).
▶
The ambient temperature must never fall below
16°C (60.8°F).
∙
Material-and property damage
due to faulty commis-
sioning.
▶ Before applying the operating voltage,
-
the exhaust heat system must be operational.
-
the defrost water outlet (see➙ Chapter 7) must be
connected.
-
the protective fi lm must be removed from the
glass doors / side panels.
Removing the protective fi lm on the inner side of the
glass doors / side panels:
∙
Open the glass door all the way (opening angle of 90°).
∙
Carefully peel off the protective fi lm with both hands
(see
➙
Fig. 7).
NOTICE
Material damage
due to damage on the coating of glass
doors / glass elements.
▶ Do not use hard, pointed objects to remove the fi lm.
▶ Put the appliance into operation immediately
after all
protective fi lm has been completely removed.

-
No cleaning is required immediately after removing
the protective fi lm.
-
Close the glass door completely and put the appli-
ance into operation.
NOTICE
Material and property damage
due to open doors dur-
ing commissioning.
The internal temperature required for
proper operation is not reached.
▶ Close the doors completely before commissioning.
