1.General/safetyinformation
Generalinformation These installation and maintenance instructions only apply to WOLF CRL
ventilation units. Authorised personnel should read these instructions before
any commissioning or maintenance work. Observe the instructions given 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 symbols are used in these instructions. This important
informationconcernspersonalaswellasoperationalsafety.
"Safetyinformation"isasetofinstructionswhichyoumustfollowexactly,
topreventrisksorinjuriestoindividuals,anddamagetotheunit.

topreventtheunitmalfunctioningoratngdamaged.
Please
note
Only qualied and trained personnel may be appointed for the installation,
commissioning, maintenance and operation of the unit.
Only qualied 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 unit when it is in perfect technical condition. Any faults or
damage which impact or might impact upon the safety or correct function of
the unit must be remedied immediately by qualied personnel.
Only replace faulty components and equipment with original WOLF spare parts.
Theunit 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.
Please
note
Safetyinformation In addition to installation and maintenance instructions, there are notes attached
to the unit in the form of labels. These must also be observed.

1.General/safetyinformation
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 inuences. 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.
Recommendedtemperatures The ventilation unit is designed for air intake temperatures between -20 °C
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.

- MicroMax 370W TWHE control unit operating instructions
- Wiring diagram
- WRS-K conguration wizard
- Commissioning report / Parameter list
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 ventilation units are designed to heat and lter normal air. 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 on-site modication 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).
According to DIN 1886, tools must be used to open the unit. Wait for the fan to
reach standstill (2 minutes). 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.
Removal and disabling of safety and monitoring equipment is prohibited.
Only operate the system in perfect technical condition. Ensure that any faults
or damage that may impact on safety are rectied immediately.

11.Delivery/handling
Delivery CRL ventilation units are supplied in packaging that protects them from dirt
and damage. Upon receipt of the goods, check the unit for possible transport
damage. If there is any damage or even a suspicion of damage, the recipient
must indicate this on the consignment note and have it countersigned by the
haulier. The recipient of the goods must notify WOLF of the relevant facts
without delay.
Dispose of the transport packaging in accordance with local regulations.
Storage Only store the ventilation unit in dry rooms at an ambient temperature
between -25 °C and +55 °C. If it is stored for a long time, ensure
that all apertures are sealed against air and water ingress.

11.Delivery/handling
The CRL internal devices in the sizes 3500/ 4800/ 6200/ 9000 can be dismantled
into three parts to make them easier to carry in. (narrow stairwells, lifts, etc.)
The unit sections are connected with hexagon bolts at unit connectors with
captive nuts. Electriclines and control cables canbe disconnected andconnected
again quite simply by means of plug-in connections in the control unit casing.

Generalhandlinginformation Units are supplied fully assembled and fully wired.
Only transport units in their installation position.
Never tilt the unit when transporting it through doorways or in narrow stairwells
(lifts).
Failure to observe these instructions can damage internal components

When lifting the CRL-A external units with the aid of eyebolts, use lifting ropes
that provide a minimum eyebolt distance L. Keep ropes at the same length.

Assemblingunitsections Before assembling the individual unit sections, ensure that they are
pushedtogethercompletely.
The assembly of cube components can be simplied by using lashing straps.
Position unit sections next to each other and pull them together with lashing
straps. Then screw the components together via the unit connectors. In order
to ensure a secure threaded connection, screw the hexagon bolts manually
into the captive nuts during assembly. Only then should they be tightened, for
example, with an electric screwdriver.
Subsequently, route the wiring harnesses back to the control unit and plug them
in (observe the cable designations).
Remove damper
xing screws
Undo the unit connector bolts with an SW13 spanner to dismantle the unit.
Remove lters before dismantling in order to reach the rear unit connectors.
It may be necessary to remove the dampers in order to gain better access to
the rear unit connectors in this area.

Before dismantling the unit, disconnect the wiring harnesses from the control
unit.
- Remove control unit cover
- Undo cable plug-in connections (Fig. 1)
- Pull wiring harnesses into the slant of the thermal wheel heat exchanger
(Fig. 2)
- Pull wiring harnesses left and right into the external parts (Fig. 3)
