3 Design and function

3.1 Unit description

The indoor unit on the split-design combined room

air conditioners 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 to be mounted high up on the

wall, in an indoor area. It is operated by an infrared

remote control.

The indoor unit consists of a fin evaporator, evapo-

rator fan, controller and condensate tray. The

indoor unit can be combined with REMKO outdoor

units from the series MVT 602-1402 DC that pro-

vide sufficient cooling capacity. The outdoor unit is

controlled by the regulation of the indoor unit.

Condensate pumps are available as accessories.

units.

4 Operation

4.1 General notes

The indoor unit is easily operated using the

standard infrared remote control. The indoor unit

beeps to acknowledge the correct transmission of

data. If it is not possible to program the indoor unit

with the remote control, then it can also be man-

ually operated.

Manual mode

The indoor unit can also be switched on manually

if the infrared remote control is lost/defective.

Manual operation is intended for emergency oper-

ation and is not suitable for basic unit operation.

Please replace the remote control. The key for

manual activation is located below the housing

cover on the right side.

The following settings apply for manual operation:

Pressing once: Automatic mode,

Pressing twice: Cooling mode,

Pressing three times: Unit OFF

Infrared remote control

The infrared remote control sends the programmed

settings a distance of up to 6 m to the receiver of

the indoor unit. Data will only be received correctly

if the remote control is pointed at the receiver and

no objects are obstructing the transmission path.

wo AAA batteries must be inserted into the

remote control in preparation. To do so, remove

the flap from the battery compartment and insert

the batteries the correct way around (see mark-

ings). Removing the batteries causes all stored

data to be lost. The remote control will then access

the default settings, which you are free to cus-

tomise at any time.

max. 6 m

Fig. 4: Maximum distance

Alarms are indicated by a code (see chapter

roubleshooting and customer service).

NOTICE!

Immediately replace flat batteries with a new

set, otherwise there is a risk of leakage. It is

recommended that the batteries are removed if

the equipment is shut down for longer periods.

Help save on energy consumption in stand-by

mode! If the device, system or component is not

in use, we recommend disconnecting the power

supply

. Components with a safety function is

excluded from our recommendation!

SLEEP function

The sleep function saves energy while you sleep.

This function is activated by pressing the key on

the remote control. Press the key before going to

sleep. In cooling mode, the unit automatically

increases the set room temperature by 1 °C after 1

hour

. After one more hour, the room temperature is

increased by an additional 1 °C. In heating mode,

the room temperature is decreased within the first

two hours of operation by 2°C. After 7 hours of unit

operation, the unit switches off automatically in

cooling and heating mode.

This function is not available in the modes recircu-

lation and dehumidification!

5 Installation instructions for qualified personnel

5.1 Important notes prior to instal-

lation

Observe the operating manuals for the indoor unit

and the outdoor unit when installing the entire

system.

n T

ransport the unit in its original packaging as

close as possible to the installation location.

You avoid transport damage by doing so.

n Check the contents of the packaging for com-

pleteness and check the unit for visible trans-

port damage. Report any damage immediately

to your contractual partner and the shipping

company.

n Lift the unit on the corners and not on the

refrigerant or condensate drainage connec-

tions.

n The refrigerant piping (injection and suction

pipe), valves and connections must be insu-

lated against vapour density. If necessary also

insulate the condensate drainage line.

n Select an installation location which allows air

to freely flow through the air inlet and outlet

(see section "Minimum clearances").

n Do not install the unit in the immediate vicinity

of devices which generate intensive thermal

radiation. Installation in the vicinity of thermal

radiation reduces the unit output.

n Install the refrigerant piping from the indoor unit

to the outdoor unit.

n Seal off open refrigerant piping with suitable

caps or adhesive strips to prevent the infiltra-

tion of moisture and never kink or compress

the refrigerant piping.

n Only use the union nuts supplied with the

refrigerant piping. These should only be

removed shortly before connecting the refrig-

erant piping.

n Carry out all electrical wiring in accordance

with applicable DIN and VDE standards.

n Ensure the electrical cables are properly con-

nected to the terminals. Otherwise there is a

risk of fire.

5.2 Installation materials

The indoor unit is attached to the wall by a wall

bracket and 4 screws (to be provided by the cus-

tomer).

5.3

Selection of installation loca-

tion

The indoor unit is designed for horizontal wall

installation above doors. However, it can also be

used in the upper wall area (min. 1.75 m above the

floor).

5.4 Minimum clearances

Observe the minimum clearances to allow access for maintenance and repair work and facilitate optimum air

distribution.

5.5 Connection variants for the indoor unit

The following connection variants can be used for the refrigerant, condensate and control lines.

Fig. 19: Connection variant (view from the rear)

A: Infeed of the refrigerant piping at the wall, left

B: Infeed of the refrigerant piping through the wall,

left

C: Outlet through the wall, right

D: Outlet at the wall, right (the refrigerant piping

must be bent through 180 degrees for this)

5.6 Connection of the indoor unit when the refrigerant piping is installed

under the plaster

If the customer routes the refrigerant piping to the unit underneath the plaster, observe the following note.

The principal connection options can be found in the "Connection variants for the indoor unit" and "W

all

bracket" chapters.

If the refrigerant piping is routed underneath the plaster, ensure that the customer-fitted refrigerant piping

does not protrude from the wall at a 90° angle. As a result of the required bending radius, the unit would then

be very difficult to connect or would possibly be impossible to fasten to the wall mount.

For this reason, route the customer-fitted refrigerant piping with as flat an angle as possible (<30°) out of the

wall, from the left and into the unit. This enables direct connection of the refrigerant piping (see Fig. 20).

NOTICE!

The flare connection should be implemented in the unit in the case of under-plaster installations. A

detachable connection below the level of the plaster is not generally permitted!
