Duct preparation 7.1
Notes
● Only use folded spiral-seams ducts that
match the nominal diameter. Ø 250 to
Ø 630 ducts are approved, depending on
the unit type.
● Connect the ducting to the Quickbox using
flexible cuffs, e.g. Maico EL.., in order to
prevent the transmission of vibrations
to the duct system.
● Install an air filter, e.g. Maico TFE, if ope-
rating the unit in a dusty environment.
 Insulate the channels (diffusion resistant)
from outside as far as the ventilation unit,
in order to avoid the build up of conden-
sation on the outside of the exhaust air
channel.
 The duct insulation must be completed
according to the recognized rules of
technology.
 Mask the joints well and decouple the wall
and roof outlets with strips of insulation.
 Insulate the supply and exhaust air ducts
outside the thermal building envelope if the
ducts pass through a cold area.
Prepare condensation drainage 7.2
(only ESQ.. K and DSQ.. K units)
Any condensation that occurs in the
Quickbox must be fed off through a
correctly-fitted condensation run-off.
Drain hoses and siphon must be
made available by the customer.
Recommendation: Use a comercially
available ½" ball-siphon.

Installation
Unit installation 8.1
As far as possible, install the
Quickbox such that there is no
transfer of vibrations to the duct
system, e.g. by using Maico EL..
flexible cuffs and vibration dampers.
Depending on the installation position,
the Quickbox is used for air extraction
or ventilation. See information sign on
the housing.
ESQ.. und DSQ..-Standard unit
 Unlock and remove side panel [3]. If re-
quired, also remove side panels [2] and [4].
 Insert the side panels into the housing in
accordance with the installation situation
and screw down.
Make sure that there is free access
to side panel [3].

Screw the unit securely to the ceiling, wall,
floor or bracket. Make sure you have
available amply dimensioned mounting
material.
 Install suitable folded spiral-seams duct.
Make sure that the ducting is not
twisted when you fit it.
ESQ.. K and DSQ.. K unit
Make sure that there is free access to
side panel [8].
 Carefully tip the unit on its side. Ensure
