REMKO RVD 351 DC - Manual (Page 17)

■ Make special preparations
regarding the oil return if the
outdoor component is located
above the indoor unit. (See sec-
tion "Oil return flow measures").
■ Add refrigerant if the basic
length of the refrigerant pipe
exceeds 5 metres.
The quantity of additional refrig-
erant is given in chapter "Add
refrigerant".
■ Only use the union nuts for the
refrigerant pipes included in
the delivery, and remove them
shortly before connecting the
refrigerant pipes.
■ Establish all electrical connections
in accordance with the relevant
DIN- and VDE standards.
■ See electrical connection diagram
Always properly insert electrical
cables into the electrical ter-
minals. Otherwise a fire could
result.
Wall openings
■ A wall opening of at least 70
mm diameter and 10 mm slope
from the inside to the outside
must be made for each indoor
unit.
■ We recommend that the inside
of the hole is padded or lined,
e.g. using a PVC tube, to pre-
vent the pipes being damaged.
■ After installation, the wall
opening should be closed off on
the building side with a suitable
sealant. Do not use materials
containing cement or lime!
Installation material
The indoor unit is fastened
using a wall bracket and 4 threaded
screws (provided by the customer).
The outdoor component is at-
tached with 4 screws and a wall
bracket to the wall or fixed by a
floor bracket to the ground.

Selection of the installation
location
Interior unit
The indoor unit is designed for
horizontal wall installation above
doors. However, it can also be
used on the upper wall area
(min. 1.75 m from upper edge of
floor).
Exterior unit
The outdoor component is de-
signed for horizontal base instal-
lation in outdoor areas. It should
be placed on level, flat and firm
ground. The unit should also
be secured to prevent toppling.
The outdoor component can be
set up outside as well as inside a
building. For external installation,
please observe the following notes
to protect the unit from weather
conditions.
Rain
The unit should be at least 10 cm
off the ground when mounted on
the roof or ground. A floor bracket
is optionally available.
Sun
The liquefier on the outdoor unit
radiates heat.
Exposure to direct sunlight will
further increase the temperature of
the fins and reduce the heat out-
put of the finned heat exchanger.
The outdoor unit should therefore
be installed as near as possible to
the north side of the building. If
necessary, take measures to pro-
vide sufficient shade (responsibility
of customer). One possible solu-
tion is to build a small roof. These
measures should not affect the
flow of warm outlet air.
Windbreak
Wind
Wind
If the unit is being installed in
windy areas, ensure that the warm
outlet air discharges in the main
wind direction. If this is not the
case it may be necessary to install
a windbreak (provided by the cus-
tomer). Ensure that the windbreak
does not adversely affect the air
intake to the unit.
