2. Safety instructions
Always follow the safety instructions in this chapter when
installing, using or performing maintenance on this air
heater:
2.1. Installation
CAUTION! This air heater must be installed and
maintained by an authorized, qualified and competent
installer, using calibrated equipment.
NOTICE This air heater must be installed and maintained
in accordance with this manual, national and local building
regulations and local health and safety regulations.
2.1.1. Protection against dust
CAUTION! Cover the air heater while spreading sawdust
on the floor. This prevents large amounts of dust from
accumulating on the heater.
CAUTION! The air heater can be used in a dusty
environment (e.g. a poultry shed) if they are cleaned and
maintained more frequently.
2.1.2. Temperature
CAUTION! Do not install the heater in places where the
temperature can rise above 40°C. Higher temperatures
cause the internal components to degrade much faster.
2.1.3. Corrosive vapours
WARNING! Do not install the air heater in areas that
contain any corrosive or explosive vapours. Corrosive
vapours (e.g. containing Chlorine) that are sucked into the
air intake will cause corrosion of the heat exchanger and a
leakage of condensate and flue gas. This is also the case
for the room thermostat.
2.2. Use
CAUTION! Make sure the area around the air heater is
dry when performing maintenance on the air heater.
CAUTION! Always close the doors and inspection hatches
of the air heater, except when adjusting and checking the
appliance.
2.2.1. Maximum CO2concentrations
This air heater uses oxygen from the surrounding air for
the combustion process. CO2is formed and emitted as a
result. Too much CO2in the air may be harmful to people,
animals and crops.
DANGER! Never allow the CO2concentration to rise
above the values shown in the table below!
Maximum CO2concentration
Poultry shed 0.3% 3,000 ppm
Greenhouse 1% 10,000 ppm
DANGER! This air heater may emit carbon monoxide
(CO) when the oxygen level in the surrounding air is too
low. Carbon monoxide is extremely dangerous. Ensure
sucient ventilation to prevent this from happening.
WARNING! The minimal ventilation requirements for a
room in which this air heater is installed is 1000 m3/h for
each 100 kW of installed power.
2.3. Maintenance & Cleaning
Frequent maintenance and cleaning of the air heater is
necessary to ensure safe and proper operation. Failure
to do so could lead to damage to the heater or its
surroundings and void the warranty.
CAUTION! Air heaters installed in a dusty and/or wet
environment must be maintained and cleaned more
frequently.
CAUTION! Air heaters installed in poultry sheds must be
maintained and cleaned after every cycle.
CAUTION! Always have a service technician inspect
and maintain the heater every year for reliable and safe
operation.
2.3.1. Protection from water (IP class)
WARNING! Never use water when cleaning electrical
parts.
This air heater is protected against splash water and has
an IPX4D classification.
WARNING! Do not use a pressure washer to clean parts
that contain electronics, such as the electric motor or the
machine cover.
