Inspection of the refrigeration installation
■
Replaced electrical components must be suitable for the application and comply with
the specifications provided by the manufacturer. Replace any defective components with
original spare parts only.
■ Replace components according to the recommendations issued by the company of
Kospel. Contact Kospel technical service if necessary.
Carry out the following checks:
■
Check the operation of the ventilation. Ventilation openings must not be blocked or
obstructed.
■
If a system with hydraulic decoupling is used, check the secondary circuit for the
refrigerant.
■
Inscriptions and symbols must be clearly visible and legible. Replace any illegible
inscriptions or symbols.
■
Refrigerant lines or components must be fitted in such a way that they do not come into
contact with corrosive substances.
Exception: refrigerant lines are made of a corrosion-resistant material or are reliably protected
against corrosion.

Inspection of electric components
■
When carrying out maintenance and repair work on eclectic parts, safety checks must
be carried out: see below.
■
If a safety-critical fault occurs, do not connect the installation until the fault has been
rectified. If it is not possible to rectify the fault immediately, a suitable interim solution
for the operation of the installation must be found if possible. Notify the user of the
installation
Carry out the following safety checks:
■
Discharging of capacitors: ensure that no sparks are generated during the discharge
process.
■
When filling or draining the refrigerant, as well as when flushing the refrigeration circuit,
do not place any electrical parts or live wires near the device.
■
Check the earthing connection.
8
Repairs to sealed casings
■
During work on sealed components, the device must be powered off before the sealed
cover is removed.
■
To warn of a potentially hazardous situation, a permanently operating refrigerant detector
should be placed at critical locations.
■
Particular care must be taken when working on electrical parts so as not to modify
the casing in a way that weakens its protective effect. This applies to a damage to
cables, the creation of too many connectors on one connection terminal, the creation
of connectors that do not meet the manufacturer’s requirements, damage to seals and
incorrect installation of cable feed-throughs.
■ Ensure that the unit is installed correctly.
■
Check that the seals are properly installed. Thereby, check that the seals reliably protect the
device against the penetration of a flammable atmosphere. Replace any damaged hoses.
! Attention
Silicone as a sealing agent may affect the performance of a leak detection devices. Do not
use silicone as a sealing agent.
■ Spare parts must comply with the manufacturer’s guidelines.
■
Work on components that are suitable for flammable atmospheres: these components
do not need to be powered off.
9
Repairs to parts that operate in a combustible atmosphere:
■ Unless it can be established that the permissible voltage and current values will not be
exceeded, no capacitive or inductive loads must be connected to the device.
■ Only those components that meet the requirements for operation in a flammable
atmosphere may be connected to voltage in a flammable atmosphere.
■ Use only original spare parts or parts approved by the Kospel company. In the event of
a leak, all other parts may ignite the refrigerant.
10
Wiring
■
Check that the wiring is not exposed to wear, corrosion, stretching, vibration or any adverse
environmental conditions and that it is not located near sharp edges.
■
When inspecting, also consider the effects of ageing and the effects of continuous vibration
on the compressors and fans.
