1.5 Safety-conscious working
The safety notes contained in this manual, the
existing national regulations concerning accident
prevention as well as any internal company
working, operating and safety regulations must be
observed.
1.6 Safety instructions for the oper-
ator
The operational safety of the units and compo-
nents is only assured providing they are used as
intended and in a fully assembled state.
nThe units and components may only be set up,
installed and maintained by qualified per-
sonnel.
nThe existing regulations concerning accident
prevention must be adhered to.
nDo not operate units or components with
obvious defects or signs of damage.
nContact with equipment parts or components
can lead to injuries.
nEnsure that electrical energy does not pose a
risk.
nRegulations of the VDE and the local energy
supply company must be adhered to.
NOTICE!

NOTICE!
Material damage due to mineral oils!
Mineral oil products permanently damage
EPDM seal elements; the sealing properties
may therefore be lost. We do not take responsi-
bility or provide warranty replacements for
damage caused by seals that are damaged in
this way.
–It is essential that you prevent EPDM from
coming into contact with mineral oil sub-
stances.
–Use a lubricant that is free of mineral oil and
has a silicone or polyalkylene basis, such
as Unisilkon L250L and Syntheso Glep 1
made by Klüber, or a silicon spray.
1.7 Safety notes for installation and
inspection tasks
nThe operator must ensure that all inspection
and installation work is carried out by author-
ised and qualified personnel who have thor-
oughly read the operating manual.
nWork on the noise protection hood may only
ever be carried out when the system is sta-
tionary.
nAppropriate hazard prevention measures must
be taken to prevent risks to people when per-
forming installation, repair, maintenance or
cleaning work on the units.
nThe setup, connection and operation of the
units and its components must be undertaken
in accordance with the usage and operating
conditions stipulated in this manual and comply
with all applicable regional regulations.
nRegional regulations and laws as well as the
Water Ecology Act must be observed.
nThe units and components must be kept at an
adequate distance from flammable, explosive,
combustible, abrasive and dirty areas or
atmospheres.

2.4 Fire classification
Fire behaviour of building materials and com-
ponents (DIN 4102-1)
In DIN 4102-01, differentiation is made between
non-combustible (A1, A2) and combustible (B1,
B2, B3) building materials. This concerns the ver-
tical flame treatment of the test specimens. In addi-
tion to the fire speed, a fire shaft test (flue gas tem-
perature) is also conducted for the B1
classification.
EPP is classified among the combustible building
materials, which can be sub-categorised as fol-
lows:

3 Product description
The noise protection hood is suitable for use in
regions with high requirements for low noise emis-
sions. The EPP housing, the specially-developed
air intake and air outlet openings reduce noise sig-
nificantly, which also enables installation in resi-
dential areas. The complete encapsulation protects
the heat pump against the effects of weather such
as hail, UV radiation and snow, as well as against
external damage or vandalism. The simple layout
thanks to the modular construction ensures easy
installation and fast access to the unit.
Features/equipment:
nSimple installation thanks to the modular con-
struction; suitable for use in conjunction with
REMKO WKF 70,120, 180 and 180 DUO heat
pump outdoor units.
nBlack or silver and black housing colour
nSound power level reduction of up to 15 dB(A)
A proper installation surface for stability with the
option to affix the sound protection hood and pro-
tection against plant growth from below must be
guaranteed.
The customer must provide suitable options for
frost-proof removal of the condensate that accu-
mulates.

heating mode.
A condensate tray should be installed on the
underside of the unit to drain any condensate.
nThe condensate drainage line must be pro-
vided by the customer and have an incline of at
least 2%. If necessary, fit vapour-diffusion-
proof insulation.
nWhen operating the unit at outside tempera-
tures below 4 °C, ensure the condensate
drainage line is laid to protect it against frost.
The lower part of the housing and condensate
tray is also to be kept frost free in order to
ensure permanent draining of the condensate.
If necessary, fit a pipe heater.
nFollowing installation, check that the conden-
sate run off is unobstructed and ensure that the
line is durably leak tight.
Safe drainage in the event of leakages
The REMKO oil separator OA 2.2 fulfils the fol-
lowing list of requirements from regional regula-
tions and laws.
NOTICE!
Local regulations or environmental laws, for
example the German Water Resource Law
(WHG), can require suitable precautions to pro-
tect against uncontrolled draining in case of
leakage to provide for safe disposal of escaping
refrigerator oil or hazardous media.
NOTICE!
With the connection of an external drain line to
the oil separator, it must be kept frost-free.

In order to assemble the noise protection hood,
proceed as follows:
1. Install the outdoor unit with the relevant floor
consoles and the condensate catch pan as
described in the relevant installation manual
for the heat pump/air conditioning unit.
REMKO recommends using the REMKO BK
600 plus floor consoles for installation. If the
noise protection hood is retrofitted to an out-
door unit that is already installed, the floor
consoles such as the REMKO BK 1000 plus
must be installed at right angles to the out-
door unit as described in point 3. Minimum
distance to the floor = 20 cm!
Fig. 6
2. The noise protection hood must be installed
on a base that is defined as suitable
according to the dimensions. It can be
installed on a foundation that is manufac-
tured separately or on ground that is pre-
pared for the installation (see the drawings in
Ä Chapter 4 ‘Setting up the outdoor unit and
the noise protection hood’ on page 17 and
11). Start with the bottom aluminium frame
when installing. Ensure that the aluminium
frame is connected securely to the base (e.g.
using anchor bolts, ground anchors or fixed
screw connections) so that the entire noise
protection hood is attached securely.
Fig. 7
3. Place the installation frame (
Ä ‘Components
on the noise protection hood’ on page 19,
item 7 ) over the heat pump's outdoor unit
and arrange the frame so that it has an even
gap all around the unit. Check whether the
relevant holes to attach the noise protection
hood enable it to be attached securely. As
there are several options for this, there are
no installation materials included with the
SWK noise protection hood for attaching.
These attachments must be provided by the
customer.

4. If the refrigerant piping is laid visibly from the
rear for installation on the outdoor unit
(Fig. 9), the frame must be installed below
the piping. If the refrigerant piping is installed
on the outdoor unit from the bottom and is
not in the vicinity of the ring elements on the
noise protection hood, you can continue
installation without an opening. If this is the
case, continue installation as described in
point 7.
