4. Electrical connections
Before starting installation ensure that the
WARNING!
electrical circuit you are working on has been shut off.
The appliance must be earthed!
4.1 230Vac supply
The installation must comply with all applicable local and/
or national standards i.e. NEN 1010.
There should be a suitable electrical circuit with a main
fuse. There is an electrical diagram further on in this guide.
The power supply is 230Vac (50 Hz) with earth.
The fan must to be equipped with a 230Volt isolation
switch or power plug. This switch should disconnect phase
and neutral (not earth) and have a 3mm contact opening
at least. Switches or power plugs must be accessible at all
times. For power supply, the fan has been provided with a
3-pole power plug (female). The installer should connect
a 3-wire mains cable and a power plug to it.
4.2 Connection options
4.2.1 Connection without speed control
The SD fan is provided with a 230 Volt thermostat (unless
requested otherwise).
Once the installer has connected the unit to the mains
electrical supply (see paragraph 4.2) it is ready for use.
The fitted thermostat should be set to the temperature at
which the fan is required to be switched on (typically 4 to
7
C above ambient set-point). Read paragraph 5.1 for a
O
correct temperature setting.
4.2.2 Connection with speed control.
When the user wishes to control the fan speed, a 5-stage
switch can be added to the installation. This switch can
transform the current to the fan motor in stages.
Function: The 5-stage speed control is connected to the
power supply of the SD fan. Depending upon the chosen
stage, the fan will run fast or slowly.
Before installation also consult the manual for the 5 stage
switch. See chapter 11, diagram 2.
5. Setting, operation and maintenance
WARNING!
Before starting maintenance make sure that
the electrical circuit you are working on has been isolat-
ed.
The appliance must be earthed.
5.1 Setting the thermostat
Set the thermostat of the SD unit approx. 4 to 7°C above
the ambient temperature desired at 1.5m above floor
level. The smaller the difference between the room ther-
mostat setting and that of the SD destratification fan, the
longer the unit will be operative.
5.2 Operation
The SD does not need manual control, it is automatic.
Generally temperature setting has to be done by
the installer. The user is allowed to do following settings:
•
Set the temperature at which the fan should ven-
tilate.
•
Turn ON/OFF main switch
•
Change fan speed by selecting one of the 5 stages
on the 5-stages switch.
ATTENTION!
Attention:
Do not set the louvres at an angle greater
than 20°. This will reduce the air volume and in turn the
throw.
5.3 Maintenance
In areas where heavy dust is present, it may be necessary
to clean the fan & guard with compressed air once a year.
If the guard is covered with severe dust, the fan will not
provide optimal performance.
Check if the appliance turns ON and OFF as it should on
the thermostat.
Pay attention on:
•
The ON and OFF switching from the thermostat
•
The smooth rotation of the fan
•
Remove the dust from the appliance
•
Check that the fan does not have severe vibration
because of unbalance on the fan blades
