The indoor unit on the split-design
combined room air conditioning
units serves to extract heat from
the indoor room being cooled. The
outdoor unit then expels this heat
to the outside.
If combined heating/cooling units
are operated as heaters, the heat
absorbed by the outdoor unit can
be discharged by the indoor unit
into the room being heated.
The unit is designed for installation
high up on indoor walls. Operation takes place using an infrared
remote control.
The indoor unit consists of a fin
vaporiser, vaporiser fan, controller
and condensation pan. The indoor
unit can be combined with REMKO outdoor units of series MVT
600/900/950/1050 DC with sufficient cooling output. The outdoor
component is controlled via the
controller of the indoor unit.
Condensation pumps
are available as an accessory.

In cooling mode, the air in the room is cooled down to the set nominal
temperature. The desired room temperature is set with the ▲/▼buttons in
1 °C increments. If the room temperature is 1 °C above the selected nominal
temperature, the indoor unit starts to cool the air in the room. The inverter
controller checks the difference between the adjusted nominal temperature
and the actual room temperature. If there is a large difference, the cooling
output is very high. If the difference is smaller, a lower cooling output is
produced. This serves to maintain extremely even air discharge temperature
and room temperature.
If the adjusted room temperature is lower than approx. 2 °C, then the control system turns the cooling function off. To protect the compressor, the
controller only turns the cooling on again after a waiting period of 3 minutes.

In dehumidifying mode, the room temperature is set to 24 °C. Due to the
low temperature of the refrigerant, the dew point of the air on the vaporiser
is lower. The excess moisture in the air is condensed by the vaporiser, the
room is dehumidified. The fan speed should be set to automatic in order to
achieve a maximum level of dehumidification. The fan speed is automatically adapted to the given circumstances.

! CAUTION
Heating mode has priority!
If an indoor unit switches over
to heating mode, then cooling
is switched off for the other
indoor devices in cooling mode.
Cooling is not possible during
heating mode.
In heating mode, you can heat the room in spring or autumn. The desired
room temperature is set with the ▲/▼ buttons in 1 °C increments. If the
room temperature is 1 °C below the selected target temperature, the indoor
unit starts to heat the air in the room. The inverter controller checks the
difference between the adjusted nominal temperature and the actual room
temperature.
If there is a large difference, a higher cooling output is produced.
If there is a small difference, a lower cooling output is produced.
This serves to maintain the air discharge temperature and the room temperature.
If the adjusted room temperature is still exceeded by approx. 2 °C, then
the control system turns the heating function off. To protect the compressor, the controller only turns the heater on again after a waiting period of 3
minutes.
In heating mode, the indoor unit fan motor is switched on after a delay, in
order to prevent the discharge of cold air.
The fins on the outdoor unit could ice up at low outdoor temperatures.
Regular reversal of the cooling circuit results in a defrosting action.
The display shows "H1" during the defrosting period.

Installation instructions for qualified personnel
Important notes prior to
installation
For installation of the entire system, observe the operating instructions of the indoor unit and the
outdoor unit.
■
Transport the unit in its original
packaging as close as possible
to the installation location.
This avoids transportation damage.
■
Check the contents of the
packaging for completeness
and check the unit for visible
transport damage.
Immediately notify any deficiencies to the contractual
partner and forwarding agent.
■
Lift the unit at the corners and
not by the refrigerant or condensation connections.
■
The refrigerant pipes (injection and suction pipe), valves
and connections to make them
tight against vapour diffusion.
If necessary, also insulate the
condensation line.
■
Select an installation location
which allows air to freely flow
through the inlet and outlet (see
section "Minimum clearances")
■
Do not install the unit in the
immediate vicinity of devices
with intensive thermal radiation. Installation near sources of
thermal radiation reduces the
output of the unit.
■
Install the refrigerant pipes from
the indoor unit to the outdoor
unit.
■
Seal off open refrigerant lines
with suitable caps or adhesive
strips to avoid the infiltration
of moisture and never kink or
compress the refrigerant pipes.
■
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.
■
Always ensure electrical cables
are properly connected to the
terminals, otherwise there is
a risk of fire.
■
Service openings should be provided in the suspended ceiling
to allow maintenance access to
the control box.
Installation material
The indoor unit is fastened using
a wall brace and 4 bolts (provided
by the customer).
In order to complete the installation, use the supplied installation
material. Appropriate dowels, trapezoidal sheet metal supports, steel
profiles, fixing clips for refrigerant
and condensation pipes (as well as
laying ducts) and connection fittings for condensation pipes must
also be provided.
Minimum clearances
Observe the minimum clearances to
allow access for maintenance,
repair work and for
optimum air distribution.

Selection of the installation
location
The indoor unit is designed for
horizontal mounting in suspended
ceilings with Euroraster dimensions. It can also be installed in
other types of suspended ceilings
with different dimensions.
Take into account the installation
height of the equipment.
Installation
NOTE
Installation may only be performed by authorised specialists.
Unit installation
The unit is mounted on four threaded rods with the cover face down.
Take into account the ceiling grid
and any other installations.
1. Use the dimensions of the ceiling cassette to mark the fixing
points for the threaded rods on
structural parts approved to support the static load, and above
the suspended ceiling.
19
Page 20
REMKO MXD
2. Fit the indoor unit onto the
threaded rods and use the
lower nuts to level the unit
(Figure 5).
3. Ensure a clearance of 35 mm
from the ceiling. Connect the
refrigerant pipes, electrical
cables and condensation pipe
to the indoor unit as described
below.
4. Check that the unit is level.
5. The final task is to tighten the
counternuts and attach the
cover.
5 Hooking in the unit
Structural component
Connecting the
refrigerant lines
The refrigerant lines on the MXD
200-520 should be connected by
the customer to the centre of the
long side.
It may be necessary to fit a reducing or extending adapter to the
indoor units. These fittings are
included with the indoor unit as an
accessory kit. Once installed, the
connections should be sealed to
prevent vapour diffusion.
! CAUTION
The units are factory filled with
dry nitrogen to check for leaks.
The pressurised nitrogen is
released when the union nuts
are loosened.
■
If the level of the condensation
pipe on the unit is above that of
the outlet, route the pipe vertically upwards (max. see P. 21)
and then with a fall to the drain.
■
Lead the condensation line
freely to the run-off line. If the
condensation runs directly into
a sewer pipe, fit a trap to prevent
any unpleasant odours.
■
When operating the unit at
outdoor temperatures below
4 °C, ensure the condensation
pipe is laid to protect it against
frost.
If necessary, fit supplementary
pipe heating.
■
Once the pipe has been
laid, check the condensation
drains off and
permanently seal it.

Condensate drain
If the temperature falls below the
dew point, condensation will form
on the cooling fins during cooling
mode.
A collection tray together with
a condensation pump and float
switch are fitted as standard below
the cooling fins. Should the float
switch trip a protective shutdown
due to inadequate removal of the
condensation, the pump will switch
on immediately and run on for approx. three minutes.
■
The condensation pipe should
have a fall of min. 2 %. This is the
responsibility of the customer.
If necessary, fit vapour diffusion
proof insulation.

The unit's scope of delivery includes
a five metre long, four-core control
line for connecting the indoor unit
to the outdoor unit. The control line
to the outdoor unit contains a data
cable which makes communication
between the indoor unit and the
outdoor unit possible. This is used
for controlling cooling and heating output and for forwarding fault
indications to the indoor unit.
If the length is insufficient, you can
extend these control lines on the
indoor unit.
■
We recommend to install a main
/ repair switch on the building
near the indoor unit.
■
The terminal blocks for making
the connections are located at
the rear of the unit. When the
unit is installed, measurements
can be made from the front by
removing the cover.
