Description of the
equipment
The outdoor unit serves to output
the heat extracted by the indoor
unit from the room being cooled.
In heater operation, the heat taken
up by the outdoor unit can be
discharged by the indoor unit into
the room to be heated.
In both operating modes,
the output produced by the
compressor precisely matches
requirements, and thereby
regulates the nominal temperature
with minimal temperature
deviations. This "invertertechnology" enables power saving
over a conventional split-system
and also reduces noise emissions
to a particularly low level.
The outdoor unit can be installed
outdoor or in indoor areas,
providing certain requirements are
met. The indoor unit is designed
for installation high up on interior
walls. It is operated via an infrared
remote control.
The outdoor unit is comprised of
a circuit containing a compressor,
a liquefier with fin vaporisers, three
electronic expansion valves and
a liquefier fan. The outdoor unit is
combinable with REMKO indoor
units of series MXW in accordance
with the cooling output (see
chapter "Combinations").
The outdoor unit refrigerant circuit
is controlled by the regulator in
the indoor unit. In order to enable
operation of the device at low
outdoor temperatures, a thermal
condenser pressure regulator
serves as winter controller to
regulate the speed of the liquefier
fan.
Floor consoles, wall consoles and
refrigerant pipes are available as
accessories.
The equipment is shipped in sturdy
transport packaging. Immediately
check the equipment on delivery
and make a note of any damage or
missing parts on the delivery note.
Inform the forwarding agent and
contractual partner.
Warranty claims at a later date will
not be accepted.

Installation instructions for qualified personnel
Important information
prior to commissioning
NOTE
Label the refrigerant pipes
(injection and suction pipes)
as well as the associated
electrical control lines of each
interior unit with a letter.
Only connect the lines to their
associated connections.
■
Observe the manuals for the
indoor unit and outdoor unit
when installing the entire
system.
■
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 thermal
radiation reduces the unit
output.
■
Only open the stop valves
for the refrigerant pipes after
installation has been fully
completed.
■
Seal off open refrigerant pipes
with suitable caps or adhesive
strips to avoid the infiltration
of moisture and never kink or
compress the refrigerant pipes.
■
Avoid unnecessary bends. This
minimises the pressure loss
in the refrigerant pipes and
ensures that the compressor
oil can flow back without
obstruction.
■
Make special preparations
regarding the oil return if the
outdoor unit is located above
the indoor unit.
(see section Oil return
measures).
■
Add refrigerant if the basic
length of the refrigerant pipe
exceeds 5 metres.
For the quantity of additional
refrigerant, refer to 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 connections in
accordance with the relevant
DIN- and VDE standards.
■
See electrical connection
diagram Ensure the electrical
cables are properly connected
to the terminals, otherwise
there is a risk of fire.
CAUTION
Always pay attention to the
affiliation of the electrical and
refrigerant pipes!
The connections of the
individual circuits may not be
mixed up.
A mistake in this area can have
fatal consequences!
NOTE
Different refrigerant pipes are
required depending on the
cooling output of the indoor
unit.
Wall openings
■
The wall breakthrough must
have a diameter of min.
diameter of min. 70 mm and
a fall of 10 mm from inside to
outside for each indoor unit.
■
We recommend that the
inside of the hole is padded or
lined, e.g. using a PVC tube,
to prevent the pipes being
damaged.
(Page 11, figure 1).
■
After installation has been
completed, use a suitable
sealing compound to close
off the wall breakthrough
(responsibility of customer) .
Do not use materials containing
cement or lime!
Installation material
The outdoor unit is fastened with
4 screws and a wall bracket to the
wall or fixed by a floor bracket to
the ground.
NOTE
Only use fixing materials
which are suitable for the
given application.

Selection of the installation
location
The outdoor unit is designed for
horizontal free-standing use in
outdoor areas.
It should be placed on level,
flat and firm ground. The unit
should also be secured to prevent
toppling.
The outdoor unit can be installed
both inside and outside buildings.
In the case of outdoor installation,
please follow the instructions given
below to protect the unit against
the weather.
2 Windbreak
The unit should be at least 10 cm
off the ground when mounted on
the roof or ground.
An optional floor bracket is
available as an accessory.
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
output of the liquefier.
The outdoor unit should therefore
be installed as near as possible to
the north side of the building.
If necessary, take measures
to provide sufficient shade
(responsibility of customer). One
possible solution is to build a small
roof.
However, the discharging warm air
flow may not be affected by the
measures.
Wind
If the unit is being installed
in windy areas, ensure the air
discharges in the prevailing wind
direction. If this is not the case
it may be necessary to install
a windbreak (provided by the
customer) (Figure 2).
Ensure that the windbreak does
not adversely affect the air intake
to the unit.
The unit should be wall-mounted
in areas of heavy snowfall.
Installation should then be min.
20 cm above the expected level
of snow to prevent snow from
entering the outdoor unit (Fig 3).
An optional wall bracket is
available as an accessory.
Installation inside buildings
■
Ensure there is adequate heat
dissipation when placing the
outdoor unit in cellars, attics,
adjoining rooms or halls
(Figure 4).
■
Install an additional fan with
a rated flow comparative to
that of the outdoor unit being
installed in the room. This
is used in conjunction with
ventilation ducts to compensate
any pressure losses
(Figure 4).
■
Ensure a continuous and
unobstructed air flow from
outside, preferably using
sufficiently large air inlets
(Figure 4).
■
Comply with any regulations
and conditions affecting
the statics of the building.
If necessary, fit acoustic
installation.

4. To bend the copper tubing, use
the appropriate bending tool to
prevent kinks in the tubing.
5. Lay the refrigerant pipes from
the indoor unit to the outdoor
unit.
In doing so, ensure adequate
fastenings and and take
measures for the oil return!
6. Use the wall or floor brackets
to fit the outdoor unit against
structural parts approved to
support the static load.
Observe the installation
instructions for the brackets.
7. Ensure that structure-borne
sound is not transferred to parts
of the building.
Use vibration dampers to
reduce the effects of structureborne sound!
8. Remove the factory-fitted
protective caps and union nuts
on the stop valve connections.
These should be used during
installation.
9. Before flanging the refrigerant
pipes, ensure that the union nut
is fitted on the pipe.
10.Prepare the laid refrigerant
pipes.
(Page 12, figures 5+6)

Supplementary information
for Installation
■
When combining the outdoor
unit with indoor unit MXW
350, the connection of the
refrigerant pipes differs.
In this case, install the
expansion fittings to the
outdoor unit provided in the
outdoor unit's scope of delivery.
■
If the basic length of the
connection pipe exceeds
5 m, add refrigerant when
commissioning the system for
the first time.
(See chapter „Add
refrigerant“).

Tightness check
Once all the connections have
been established, the pressure
gauge station is attached as
follows to the Schrader valve (if
fitted):
red = small valve
= injection pressure
blue = large valve
= suction pressure.
Once connected, perform a
tightness test using dried nitrogen.
The tightness test involves
spraying a leak detection spray
onto the connections. If bubbles
are visible, the connections have
not been properly made.
Re-tighten the connection or
prepare a new flange.
If the tightness test is successfully
completed, depressurise the
refrigerant pipes and start
a vacuum pump with an absolute
final partial pressure of min.
10 mbar to remove the air in the
pipe. Any humidity present in the
pipes is also removed.
15
REMKO MVT
Electrical connection
CAUTION
A vacuum of min. 20 mbar
must be created!
The time required to generate
the vacuum is dependent on
the pipework volume of the
indoor unit and the length of the
refrigerant pipes. This always takes
at least 60 minutes.
Once any foreign gases and
humidity have been completely
extracted from the system, the
valves on the pressure gauge
station are closed and the valves
on the outdoor unit are opened
as described in the chapter on
"Commissioning".

a terminal box in the vicinity of
the outdoor unit.
We recommend that a main/
repair switch is used (Figure 9).
■
Voltage is supplied to the
indoor unit through the
connection cable between
the outdoor component and
outdoor unit.
■
Details concerning the electrical
protection of the system are
given in the technical data.
Observe the required
diameters!
■
If the outdoor unit is installed
on a roof, ensure it is protected
against lightning strikes.
■
Label the electrical control lines
and the associated refrigerant
pipes of each interior device
with the same letter (A to D).
■
Only connect the lines to their
associated connections as
labelled with the same letter.
Mixing up the assignment
of control lines and
refrigeration pipes can lead
to fatal consequences such as
compressor damage!
Proceed as follows to connect the
cable:
1. Remove the side panel next to
the terminals.
2. Select the cable cross-section
according to the relevant
standards.
3. Feed the cables through the
edge protection rings on the
fixed connection panel.
4. Insert the control lines into
the corresponding sockets. In
doing so, pay attention to the
alignment of the circuits.
5. If the supplied control lines
are too short, they can be
unclamped from the indoor unit
and extended by an electrician.
6. Support the cable in the strain
relief and re-assemble the unit.
NOTE
Additional sensor and control
lines may be required on some
indoor units.

connect the vacuum pump via the
pressure gauge station to the valve
connections on the outdoor unit
(see chapter "Tightness check")
and create a vacuum.
Perform the following checks
prior to commissioning the
unit for the first time and after
any interventions affecting the
refrigerant circuit. Record the
results in the commissioning
report:
■
Check of all refrigerant pipes
and valves with leak detection
spray or soapy water for leaks
and for inadvertent mix up of
suction and injection pipe, with
the unit at a standstill.
■
Check of all refrigerant pipes
and insulation for damage.
Add refrigerant
CAUTION
Note that the employed
refrigerant is always filled in
liquid form!
CAUTION
Wear protective clothing when
handling refrigerant.
NOTE
Check the overheating to
determine the refrigerant fill
quantity.
The unit contains a basic quantity
of refrigerant.
In addition, an additional amount
of refrigerant must be added for
refrigerant pipe lengths exceeding
5 meters per circuit. Refer to the
following chart:
Commissioning
NOTE
Commissioning should only be
performed and documented by
specially trained personnel.
Observe the manuals for the
indoor unit and outdoor unit
when commissioning the
entire system.
The system can be commissioned
once all the components have
been connected and checked.
A functional check should be
performed to verify its correct
function and identify any unusual
operational behaviour prior to
handing it over to the operator.
This check is dependent on the
installed indoor unit.
The procedures are specified in the
manual for the indoor unit being
commissioned.
■
Check of all electrical
connections between indoor
unit and outdoor unit for
correct polarity.
■
Check that all fastenings,
mountings etc. are firm and at
the correct level.

CAUTION
Be sure to check the
association of the electrical
and refrigerant pipes before
commissioning!
The connections of the
individual circuits may not be
mixed up.
Mixing up the assignment of
control lines and refrigerant
pipes can lead to fatal
consequences (compressor
damage)!
Commissioning of the
individual circuits must be
carried out successively.
Function test and test run
Check the following points:
■
Leak tightness of refrigerant
pipes.
Functional test for cooling mode.
1. Remove the protective caps
from the valves.
2. Begin the commissioning
process by briefly opening the
stop valves on the outdoor
unit until the pressure gauge
indicates a pressure of approx.
2 bar.
3. Use leak detection spray or
suitable devices to check that
all the connections are tight. If
no leaks are found, fully open
the stop valves by turning them
anti-clockwise using a spanner.
If leaks were found, draw off
the refrigerant and rework
the defective connection. It
is imperative that the vacuum
creation and drying steps are
repeated!
8. Check the control system in the
indoor unit using the functions
described in the manual.
Timer, temperature settings and
all mode settings.
9.
Check the overheating,
outdoor, indoor, outlet and
vaporisation temperatures and
record the measured values in
the commissioning report.
10.
Remove the pressure gauge.
11.
Proceed as previously described
for all other refrigerant circuits.
NOTE
Check the individual operating
parameters with the help of
the display on the outdoor
unit as described on page
22 and note the value in the
commissioning protocol.
■
Compressor and fan running
smoothly.
■
In cooling mode, cold air should
be output by the indoor unit,
and warm air should be output
by the outdoor unit.
■
Functional test of the indoor
unit and all program sequences.
■
Check of the surface
temperature of the suction pipe
and determination of vaporiser
overheating.
To measure the temperature,
hold the thermometer to the
suction pipe and subtract the
boiling point temperature
reading on the pressure
gauge from the measured
temperature.
■
Record the measured
temperatures in the
commissioning report.
4. Switch off the main circuit
breaker or remove the fuse
(provided by the customer).
5. Set the target temperature
on the indoor unit using the
remote control. This should be
set to a value lower than the
room temperature.
6. Switch the indoor unit to
cooling mode.
NOTE
Due to the turn on delay, the
compressor will start up a few
minutes later.
7. Check the correct function
and settings of all regulation,
control and safety devices
during the test run.
Final tasks
■
Use the remote control to set
the target temperature to the
required value.
■
Re-fit all the dismantled parts.
■
Familiarize the operator with
the system.
