3. Installation
Warning! Electrical appliances may only be operated in damp rooms that are protected by residual
current circuit breakers (RCD).
Warning! Before initial commissioning, check that the planned location has such a connection.
Warning! When using multiple sockets or extension cables, make sure that the maximum current
carrying capacity is not exceeded. Cable drums must always be fully unrolled.
Warning! The installation site must be selected so that the unit cannot be sprayed with water or fall
into water under any circumstances.
Warning! Do not wrap the connection cable around the unit and never operate the unit with a
wrapped cable. Always plug heaters directly into a wall outlet/receptacle. Never use with an extensi
on
cord or relocatable power tap (outlet/power strip).
Please note! Lay the connection cable so that no one can trip over it, it cannot be crushed or come
into contact with hot objects

Please note! Only use extension cables that are compatible with the output and comply with the
valid safety regulations of the unit. Connect to properly grounded outlets only.
Please note! Make sure to disconnect the unit from the mains before and during Installation.
This heater is for use on 110VAC, 50/60Hz only.
Warning! Never try to operate the device using a different voltage.
The cord has a plug as shown at A in below figure. An adapter as shown at C is available for connecting
three-blade grounding-type plugs to two-slot receptacles. The green grounding lug extending from the
adapter must be connected to a permanent ground such as a properly grounded outlet box. The adapter
should not be used if a three-slot grounded receptacle is available.

3. Installation der Palma Twin - Manuell
Warning! This heater is hot when in use. To avoid burns, do not let bare skin touch hot surfaces. If
provided, use handles when moving this heater. Keep combustible materials, such as furniture, pillows,
bedding, papers, clothes, and curtains at least a 3 feet (0.9 m) from the front of the heater and keep them
away from the sides and rear (see figure below).
Warning! If possible, leave a free space of 1.5 metres in front of the outlet opening.
Insert the plug (2.0) of the Palma Twin (1.0) directly into the mains socket (5.0).
Warning! Never insert or remove the power plug with wet hands. When using a multiple socket or an
extension cable please ensure that the maximum current carrying capacity is not exceeded. Cable drums
must always be completely unrolled. Do not wrap the connection cable around the device and never operate
the device with wound cable. Never pull the power cord itself; only remove the plug from the socket holding
the grips on the mains plug.

4. Using the Palma Twin - Manual
4.1 General operation
The Palma Twin recirculating air heater is equipped with a thermostat switch and a selector switch. With the
selection switch, you can select one of 3 possible operating modes. These are "Recirculation", "750 W heat
output" and "1.5 kw heat output".
Modi of the Palma Twin - Manual
Unit not in operation
Circulating air without heating (circulation in continuous operation)
750W heating capacity (heating controlled by thermostat, recirculation in continuous
operation)
1.5kW heating capacity (heating controlled by thermostat, recirculation in continuous
operation)
Palma Twin Operating Instructions
US

4.2 Using the Palma Twin in recirculation mode
On the selection switch, select position "Recirculation" as the mode. In this mode, there is NO heating.
Manual: Plug the Palma Twin - Manual fan heater directly into the mains socket. The Palma Twin will now
run in continuous operation. During the summer months, you can achieve a reduction in the temperature in
the greenhouse by using the recirculation mode. In this operating mode, open the door or the skylight of your
greenhouse.
Please note! In this operating mode, the position of the thermostat switch is irrelevant. The greenhouse air
heated by the sun is constantly circulated in recirculation mode and in this way transported to the outside. At
the same time, this regulates the humidity in the greenhouse and promotes pollination of your plants.

4.3 Using the Palma Twin - Manual in "750W heating mode"
If you want to heat a room or a greenhouse, use one of the two operating modes for heating. The "750W
heating mode" is selected by setting the right selection switch to the symbol. You can now regulate
the temperature with the left-hand temperature switch. If you are using the Palma Twin without a digital
temperature display, you can use a thermometer to determine the temperature in the room. If the
temperature is too high or too low, you can adjust it by turning the left thermostat switch. When the
desired room temperature is reached, slowly turn the thermostat counterclockwise until the switch-off
point is reached. The switch-off point means that the heating heats up to this point (heating is indicated by
the red signal light). If the left switch is set below this switch-off point, the fan heater does not heat, even
though you may have set the fan heater to "heating" mode. The fan heater always heats the room as soon
as the room temperature falls below the set level (switch-off point). You can also hear the switch-off point
by a "click" or recognise it by the signal light (above the switch-off point, the signal light lights up, heating
is in progress. Below the switch-off point the signal light does not light up, the Palma is not heating). If
there are temperature discrepancies, you must adjust them slightly. Due to the bimetal thermostat's
measuring tolerance of ± 41°F, it may be necessary to check the set temperature with a thermometer and
readjust if necessary.
Please note! Unfortunately, it is not possible to attach a temperature scale to the thermostat switch,
as the behaviour of each greenhouse varies depending on size, insulation, fill level and location.
The illustration shows as an example: Palma Twin set to 750W heating on level 8.

4.4 Using the Palma Twin - Manual in "1.5kW heating mode"
If you want to heat a room or a greenhouse, use one of the two operating modes for heating. The "1.5kw
heating mode" is selected by setting the right-hand selection switch to the symbol. You can now
regulate the temperature with the left-hand temperature switch. If you are using the Palma Twin without a
digital temperature display, you can use a thermometer to determine the temperature in the room. If the
temperature is too high or too low, you can adjust it by turning the left thermostat switch. When the
desired room temperature is reached, slowly turn the thermostat counterclockwise until the switch-off
point is reached. The switch-off point means that the heating heats up to this point (heating is indicated by
the red signal light). If the left switch is set below this switch-off point, the fan heater does not heat, even
though you may have set the fan heater to "heating" mode. The fan heater always heats the room as
soon as the room temperature falls below the set level (switch-off point). You can also hear the switch-off
point by a "click" or recognise it by the signal light (above the switch-off point, the signal light lights up,
heating is in progress. Below the switch-off point the signal light does not light up, the Palma is not
heating). If there are temperature discrepancies, you must adjust them slightly. Due to the bimetal
thermostat's measuring tolerance of ± 41°F, it may be necessary to check the set temperature with a
thermometer and readjust if necessary.
Please note! Unfortunately, it is not possible to print a temperature scale on the thermostat switch,
as the behaviour of each greenhouse varies according to size, insulation, filling level and location.

4.6 Safety features
Temperature controlled circuit breaker: If the device overheats the temperature-controlled circuit
breaker will switch the device off temporarily. To switch the device back on, turn the heater off for
5 to 10 minutes to cool down
Another reason for the shutdown would be blockage of the intake or outlet opening.
In this case please remove the corresponding objects. It could also be an indication that
the ventilator has failed. In this case switch the heater (1) off, remove the plug (2) from the socket (5) and
contact an authorized specialist to arrange repair.
