CABINET HEATER
5.1.1.4
Polarity Test - Single phase
Connect one lead of a suitable voltmeter to earth and connect the other lead to the live supply terminal at the heater L
1
.
Turn on power to heater. A reading of approximately 230 volts AC 50Hz should be found.
The same result should be obtained by connecting the test leads from live to neutral.
Connecting the voltmeter between Neutral N and Earth should give a reading of 0 volts. If these tests do not conform
to the above there is a fault which must be rectified before progressing further with the commission. An electrician
should be consulted to carry out this work.
Note:
The burner control box may not operate with a neutral to earth voltage above 15v. and may be unreliable at any
reading other than 0.
5.1.1.5
Polarity Test - Three Phase
Connect one lead of a suitable voltmeter to earth and connect the other lead to each live supply terminal at the heater
in turn L
1,
L
2
& L
3
. A voltage of a approximately 230v should be found between each phase and Earth or Neutral.
The voltage between and two phases should be approximately 400v.
See 'Single Phase' above for testing Neutral to Earth.
5.1.1.6
Fan Rotation Check
Switch on the electricity supply at the isolator and the manual switch to 'fan on' (if there is no remote fan switch installed
then press in the white button of the combination fan/limit thermostat). On three phase heaters check the rotation of the
main air moving fan. This should be clockwise looking at the drive end. If rotation is not correct, turn off the isolator and
change over any two of the incoming supply phases and recheck. It will be necessary to remove the lower front or right
hand side panel to see fan rotation.

Electrical Settings
5.1.2.1
Combination Fan/Limit Thermostat Settings Check
Check the settings on the combination fan/limit thermostat. The three hands from left to right should be set approximately
as follows:
Any manufacturing seals that are broken during the on site commissioning must be re-sealed following the completion
of the commissioning so that subsequent adjustment by unauthorised persons is deterred.
Hand 1
Fan Off temp
38°C
(100°F)
Hand 2
Fan On temp
60-65°C
(140-150°F)
Hand 3
Limit temp
110°C (230°F)
WARNING
DO NOT ROTATE THE DIAL BY HAND AS THIS MAY CAUSE PERMANENT DAMAGE TO THE MECHANISM.
The link must be removed between the two switches on this device (see Fig. 2.3).
5.1.2.2
Fan Motor Overload Check
On three phase belt drive heaters check the correct setting of the fan motor overload (See 2.4) this should be 0.2 amps
above the rated running current on the heater data plate or see Table 2.1.
