regulations.
GEFAHR
Units without their own cooling unit have to be installed exclusively by a specialised refrigeration rm.
Self-contained units are delivered with a 1.5 meter long power cord with an earthing contact plug as a standard feature. It is
connected to an AC power grid with a nominal AC voltage and frequency of 230 volts 50 Hz (country dependent with 115V 60Hz,
120V 60Hz, 220-240V 50-60Hz). The electrical supply line must be protected with a 16 A fuse (trip characteristic “C”).
If a plug connection is used for the mains connection, then the power outlet must be easily accessible to be able to disconnect the
unit from the power grid if need be (cleaning, maintenance work). If direct wiring is used, then a means of disconnecting the unit
from the power grid must be provided.

Check whether the unit has any transport damage and write down the damage that you discover on the transfer papers from the
freight forwarder as well as on your form. Have the damage conrmed.
Taking possession
Various dangers when disposing of refrigerants
Wear protective gloves and eye protection during the disposal of refrigerants (propane, R404A, R134A etc.). Working with
open ames is forbidden during the disposal of refrigerant. Dispose of the refrigerant properly and in an environmentally
compatible way.
Various dangers during the disposal of damaged parts/components
When disposing of damaged parts/components wear protective gloves. Dispose of damaged parts/
components properly and in an environmentally compatible way.
With self-contained units, the pipework is rmly connected to the refrigeration unit, and the refrigeration
circuit is lled with refrigerant. Display cases with expansion valves and as of a specic size have an inspec-
tion glass with a moisture indicator (for checking in case of
service). It is located beside the condenser.
Self-contained units
For services purposes, the refrigeration system including the stainless steel housing can be pulled out to the front.
Do not pull or damage the lines that are behind it!
Remote refrigeration units are designated for connection to an existing refrigeration plant provided by the customer. The copper
tubing is insulated and leads out downward through the foamed refrigerated well with convection cooling. The evaporator is equip-
ped with an expansion valve for the desired refrigerant and lled with dry nitrogen. Solenoid valves, lter dryers and possibly also
back pressure regulators must be installed by the customer. The specied evaporation temperatures as well as condensing tem-
peratures must be kept constant. Steam components must be avoided in front of the expansion valve.

2.4. ASSEMBLY AND INSTALLATION GUIDE
2.4.1. FIRST STEPS
To make damage that is caused during loading, transport and unloading traceable, all units are equipped with a socal-
led “Shockwatch® 2”. This tool makes it possible to determine at which point of the delivery chain a product is dama-
ged in order to clarify transport damage. Information on the ShockWatch® concept is stored in the QR code
(see Chapter 4.1).
NOTICE

Subject to technical modications | Valid from August 2019 19
All requirements placed on the installation site according to Chapter 1.8 must be followed in order to ensure ecient and safe
operation.
If the damage is only discovered after unpacking, then you are required to report it immediately in writing. It is advisable to notify your
supplier by phone in advance. You need the following to remove the transport packaging:
• at least two persons
• Tools:
- cordless screwdriver or Philips screwdriver for screw size 3.9x45 mm
- cutting tool (scissors or knife)
Setup
Your claim to compensation for the damage is lost if you do not report transport damage in good time.
(according to GTCs).
Avoid placing the unit near any equipment that produces a lot of steam. This can lead to heavy icing of the evaporator
and condensate on the glass and other performancereducing as well as unwanted adverse eects.
Correct installation and trouble-free operation is a requirement for putting the unit into operation. The installation must
comply with the local electrical, safety and hygiene regulations.
NOTICE

NOTICE
2.6. CONDENSATE DISPOSAL (CONDENSATE)
The condensate can be disposed of in a variety of ways (see table in Chapter 2.2).
Danger from leaking water from an open hot gas evaporation or improperly installed condensate tray
During the installation as well as operation of the unit, pay attention to a properly pushed-in condensate tray and comple-
tely closed hot gas evaporation. Manually lifting the units can lead to loosening of the locking mechanism of the hot gas
evaporation and hence to the condensate leaking out. This must be checked after the installation and before putting the
unit into daily operation. Wear safety gloves for the installation and inspection.
Units that are operated with remote refrigeration are equipped at the factory with odour traps (siphon) so that only the wastewater
connections or external condensate trays have to be installed in accordance with the local conditions. It must be ensured that was-
tewater cannot get back into the refrigeration point.
Via siphon directly into the sewer system
Self-contained units (model-dependent) are equipped with fully-automatic condensate evaporation.
Fully automatic condensate evaporation
Units with hot gas evaporation have a condensate tray. They may only be operated with the condensate tray pushed in
and completely closed.
NOTICE
WARNING
The wastewater installation may only be carried out by authorised specialists.
Electric condensate evaporation trays generate heat and moisture. To prevent damage to the condenser, they must be
installed at the greatest possible distance. The installation and assembly guide of the condensate tray can be found in
Chapter 4.1 under the QR code that is given there.
NOTICE

2.7. VENTILATION AND DISCHARGE
By default, the units are delivered with incoming air on the operator side and outgoing air on the customer side. We
recommend having the exhaust air outlet on the customer side (see variant 1). If an exhaust air outlet on the customer side
is not possible, then the exhaust air must be congured to be on the side or on the operator side (see variant 2). Make sure
that the exhaust air is not directly drawn back in, in order to ensure perfect operation.
Reduction of the cooling capacity or destruction from overheating of the refrigeration unit.
The air circulation openings of the refrigeration unit must not be blocked or obstructed! The airow must not be
interrupted or impaired. The ventilation grilles must have at least the 1.5-x cross-section of the condenser surface
