1. General notes
GB
1.1 Extract from the conditions of guarantee
No guarantee is assumed for damage resulting from
improper use, improper assembly or operation by the
buyer or other parties, natural wear, improper or negligent
handling, or chemical/electro chemical influence, insofar as
this is not our fault, or resulting from in attention to the
assembly, operating and maintenance instructions,
improper alterations or maintenance done by the buyer or
third parties, or as a result of use of parts supplied by other
manufacturers.
1.2 Requirements for installation area / Intended use
For economical operation of the refrigeration unit, the
ambient temperature should be between +5°C to +25°C.
The room must be well ventilated to remove heat
generated. Direct heat radiation on the refrigeration unit
must be avoided. Heating the room must also be avoided,
otherwise the comsumption of electrical power will
increase.
lf installed outdoors, a roof must be provided.
lf ambient temperature is below 10°C an oil heating is to be
installed. Viessmann can supply this as an optional
accessory.
The refrigeration unit is designed to provide free access in
regard to suction and release of air. lf air ducts are required,
these must be designed and installed by a cooling
specialist company.
There must be enough space in front of the suction and air
release vents of the refrigeration unit to guarantee proper
ventilation:
- at least 250 mm in front of all suction and air release
vents
Do not install units in plants where there is a danger
of fire.
According to DIN VDE 0100-482 (VDE 0100 Part 482):
1997-08 these are rooms or places in rooms or out doors
where there is a danger that, depending on the local and
plant conditions, esily flammable materials in dangerous
quantities could be close enough to the electrical
equipment such that higher temperatures or electrical
sparks could cause fire. These could be: work or drying
areas, storerooms, or parts of room, as well as such areas
outdoors, e.g. paper, wood, textile or wood working plants,
hay, straw, jute, and flax storing areas.
- According to BGR 500, chapter 2.35 or local regulations
for operation and maintenance. (qualified staff)
1.3 Transport
Because of the oil in the condenser, the refrigeration
unit may only be transported in a standing position. lf
the unit is to be transported further, only the original
packing may be used.
1.4 Supplied condition
The refrigeration unit is delivered ready for operation,
with wire and plug, packed in a carton.
1.5 Unpacking and handling
- Prior to and during unpacking of the refrigeration
unit, visual inspection must be carried out to check
if any damage occurred during transportation.
- Please inspect for loose parts, dents, scratches,
visible loss of oil, etc.
- During handling, the unit should be gripped only
on the housing or on the frame.
- Prior to disposing of the packing, it should be
inspected for presence of loose parts.
- To process any claims, we require an exact
description of the problem (with picture), as well as
the designation and serial number of the unit.
- To prevent damaging of the unit, it may only be
transported and stored in the position of use. Non
compliance will cause loss of guarantee protection.
General notice (liability): the details of this technical documents serve for description. Consents regarding the availability of certain features or
regarding a certain purpose always require a special written agreement.

1.6 Cleaning and maintenance of the refrigeration unit
During cleaning the refrigeration unit and the coldroom
should be cut off from the power supply.
Remove the plug from the power supply during such
work and secure against the plug being reinserted, or
switch off the power supply at source and secure
against switching on.
- The cooling unit should be inspected periodically after
beginning operation and, if necessary, cleaned.
Depending on requirements, the intervals between
inspection and cleaning have to be determined.The
cleaning intervals depend on the condition of the
surroundings.
- The condenser and evaporator can be cleaned with a
soft brush, compressed air or, in case of oil residues,
with a high pressure cleaner. Do not use any sharp or
pointed objects. The fins should not be bent or
damaged during cleaning.
By courtesy of intensive contamination with solvents or
outgasing synthetics natural discolorations can appear
on the SilverProtec surface. These are unproblematicly
removable with common purifiers based on oxygen or
with bleaching agents with a reaction time conforming
to the gravity of discoloration. The purifiers Vanish
Oxiaction from Hoffmanns or Sil OXIperfect from Henkel
perform well. Both products are available in trade. For
the cleaning of vertical areas on which the sprayed
purifier would slide down without a reaction time, we
recommend to spray the purifier on a cleaning rag and
then press it slightly on the discoloured spot so that the
rag doesn‘t slip off. Remove the rag after the reaction
time and wipe the treated spot again.
Pay attention to the product information!

in a Viessmann coldroom
2.1 Assembly of the condenser unit
The condenser unit is assembled outside of the coldroom.
The length of the electric cable on the evaporation unit is
15 m, including plug. This is also the maximum distance
between condenser and evaporator.
The minimum distance to the ceiling must be 250 mm to
guarantee proper ventilation
Attention!
This minimum distance must be checked prior to
assembly of the evaporator!
GB
Attention!
The assembly and installation of a split unit must be
done by an approved specialist!
Release the locking screws on the front panel (4).
Remove front panel.
Anchor the evaporation unit on the drill holes provides at
the back of the unit on the wall using the anchoring
material provided.
