Cooling The illustration only shows one sample setting. Always adjust the setting to
the current conditions.
• Press switch (1) down
• Turn the switch (5) as far as it will go, to Cold
• Turn switch (3) to the required level
• Set the air distribution with switch (4) – open
the air vents if necessary
• If switch (2) is set to recirculated air, cooling
will be quicker. However, no oxygen will be
supplied
Drying the air You can dry the air in the crane cab.
Here however, no heating or only a small amount will be produced.
• Press switch (1) down
• Turn the switch (5) as far as it will go, to
Warm
• Turn switch (3) to the required level
• Adjust the setting for fresh air/recirculated
air to the current conditions (humidity and
temperature of the outer air) using switch (2)
• Set the air distribution with switch (4) – open
the air vents if necessary
When drying, the air conditioning system and the heating system work
against each other. After drying, switch off the device that you do not
require.
