1 General / Safety information
General information These installation and maintenance instructions only apply to WOLF CRL / CRL
evo max ventilation units. Authorised personnel should read these instructions
before any commissioning or maintenance work. Comply with the specications
in this document. Installation, commissioning and maintenance work must only
be carried out by trained personnel.
These instructions should be considered an integral part of the unit
supplied, and should always be easily accessible.
Failure to observe these installation and maintenance instructions voids any
WOLF GmbH warranty.
Reference symbols The following reference symbols are used in these instructions. This
important information concerns personal and operational safety as well
as operational reliability.
“Safety information" identies instructions that must be observed to
the letter, to prevent risks and injuries to individuals and damage to the
appliance.
Danger through 'live' electrical components.
Please note: Turn off the ON/OFF switch before removing the casing.
Never touch electrical components or contacts when the ON/OFF switch
is in the ON position. There is a danger of electrocution, resulting in a
risk to health or death.
The main terminals are 'live', even when the ON/OFF switch is in the OFF
position.
Note
Safety information In addition to installation and maintenance instructions, there are notes attached
"Please note" designates technical instructions which you must observe
to prevent the unit malfunctioning or being damaged.
to the unit in the form of labels. These must also be observed.
Only qualied and trained personnel may be appointed for the installation,
commissioning, maintenance and operation of the unit.
Only qualied electricians are permitted to work on the electrical system.
VDE regulations [or local regulations] and those of your local power supply
utility are applicable to electrical installation work.
Only operate the unit within its output range, which is stated in the technical
documentation supplied by WOLF.
Only operate the appliance if it is in perfect technical condition. Any faults or
damage that impact or might impact upon the safety or correct function of the
unit must be remedied immediately by qualied personnel.
Only replace faulty components and equipment with original WOLF spare parts.
Note
It may only be used for handling air. This air must not contain any harmful,
combustible, explosive, aggressive, corrosive or otherwise dangerous
substances, as these would be distributed throughout the duct system
or building, where they could cause a risk to the health of, or even kill
the occupants, animals or plants living there.

1 General / safety information
In accordance with DIN 1886, tools are required to open the unit. Wait for the
fan to reach standstill (2 minutes wait). When the doors are opened, negative
pressure may draw in loose objects, which could destroy the fan or even cause
a risk to life if items of clothing are drawn in.
Electrical connection Make the electrical connection in accordance with local regulations.
Once electrical connection work is complete, the installation must be subjected
to a safety test in accordance with VDE 0701-0702 and VDE 0700 part 500,
as otherwise there would be a risk of electric shock that could result in injury
or death.
Before working on the unit, shut it down via the isolator.
Even when the unit has been shut down, voltage will still be present at terminals
and connections of the EC fans. This means there is a risk of electric shock
that could result in injury or death.
Do not touch the EC fans for ve minutes after disconnecting the power across
all poles.
Intended use Wolf CRL / CRL evo max ventilation units are designed to heat and lter normal
air. Max. Max. air intake temperature: +40 °C. The use of these units in wet
rooms or rooms with explosive atmospheres is not permissible. Handling very
dusty or aggressive media is not permissible.
Any onsite modication or improper use of the unit is not permissible and WOLF
GmbH accepts no liability for any damage caused as a result.
Ventilation units intended for internal installation must be placed in rooms that
meet the requirements of VDI 2050 (VDI 2050, Requirements for technical
equipment rooms - Planning and execution).
Fire The unit does not present a direct risk of re.
The small numbers of seals tted inside the unit can burn away if subjected to
external inuences. Wear respiratory equipment if you ght a re. The usual
extinguishing agents such as water, extinguishing foam or extinguishing powder
can be used to extinguish res. As there are only a small number of ammable
seals, the level of pollutants that could be released in a re is minimal.
Warnings
Recommended temperatures The ventilation unit is designed for air intake temperatures between -20 °C
Other technical documents - Operating instructions WRS-K
Removal and disabling of safety and monitoring equipment is prohibited.
The system must only be operated if it is in perfect technical condition. Ensure
that any faults or damage that may impact on safety are rectied immediately.
and +40 °C. For safety reasons, the room temperature in technical equipment
rooms must not fall below 5 °C (risk of frost) or exceed 40 °C. The unit should
be operated in room conditions of between 22 °C and 28 °C at approx. 55 %
relative humidity.
