DESCRIPTION
EK mobile electrical space heaters have been designed to
heat different kinds of locations: industrial, civil, warehouses,
building yards, public places. Air is taken from the environment
through a fan and heated by armour-plated resistances.
The fan and resistances are inside the machine and the air
comes in and out through appropriate grids. Space heaters are
made of steel sheets and provided with a double wall to
enhance machine efficiency and limit external walls
temperatures. They are provided with feet as
well, to be mounted before use. These offer optimum stability
to the machine provided it is placed on an horizontal solid
surface.
GENERAL ADVICE
Space heaters must be installed, set up and used in
accordance with current laws.
A few general guidelines should be observed:
• follow the instructions in this booklet very carefully;
• do not install the heater near showers, bathtubs or swimming
pools;
• do not place the heater immediately beneath a fixed wall
socket;
• the heater must be placed on a firm surface to avoid
overturning;
• inflammable materials must be kept at a safe distance from
theheater;
• the heater must not be covered;
• make sure the heater is always under surveillance and keep
childrenand animals away from it;
• after use make sure the disconnecting switch is off.
INSTALLATION INSTRUCTIONS
Warning
Use the four screws provided to fix the feet as shown in
the picture before using the heater.
Models WH 2must be connected to a 230V ~ grounded wall
socket, while models WH 5/9/15 are equipped with a CEE
plug to be connected to a 400V 3 ~ grounded electric mains.
Before any attempt to start the heater is made, check that your
electrical supply conforms to the data on the model plate.
Warning
Mains must be fitted with a thermo-magnetic differential
switch.
The unit plug must be linked to a socket with a mains
switch.
INSTRUCTIONS
THERMOSTAT 0-40 C°
Turn on the ON-OFF switch (a).
By setting the room thermostat to the desired temperature
level, the
heater will start and stop automatically. When the selected
temperature
level is reached, the fan only goes on for the time required
("POSTVENTILATION").
POWER SELECTOR
You can choose power delivery using the selector (b) as
follows:
TEMPERATURE-LIMIT THERMOSTAT
A temperature-limit thermostat will stop the power supply in
caseof overheating. If the thermostat releases, disconnect
fan's electricitysupply, wait until the fan has cooled down and
fix the problem causingthe overheating. In models EK3 A and
EK9 A press the RESET buttonon the heater cover to reset the
temperature-limit thermostat. In modelsEK15 A reset is carried
out at the back of the machine, next to theRESET label:
unscrew the protective hood and press the red button, replace
the hood to avoid compromising the heater insulation
protectionlevel.
POSTVENTILATION
When the room temperature reaches the value of the valve on
thethermostat, the heating stops and the fan goes on until the
resistanceshave cooled down.
TURNING OFF
To stop the appliance, turn the ON-OFF switch (a) to the "0"
position,the heating stops and the fan goes on until the
resistances havecooled down.

MAINTENANCE

Warning
Before carrying out any maintenance operation you must:
• Stop the heater;
• Turn off the disconnection switch on the electric
switchboard;
• Wait until the heater has cooled down.
