3.4 Electrical Installation

A fully qualified electrical engineer must undertake all electrical work in accordance with local regulations.
The equipment should be connected to the electrical supply through a switch or circuit breaker. This device should be clearly and indelibly
marked as the disconnecting device for the equipment and located in close proximity to the equipment and be easily accessible to the operator.
Over current protection must be fitted as part of the building installation. This protection should be selected in accordance with local and national
code regulations and based upon the technical data supplied for this equipment.
Connect power to the dryer (via the mains cable gland *) at the fused
terminal block.
The fuse terminal block is located on the small base plate under the
enclosure. Four screws retain the base plate as shown.
*For CSA / NPT dryers, the cable gland is replaced by a conduit entry
aperture.

3.5 Running the Dryer with a Minimum Pressure Above 7 bar

If the dryer is to be run with a minimum pressure above 7 bar g (102 psig) an alteration to the timer board is required.
Re-positioning the jumper extends the re-pressurisation stage of the cycle to ensure that the unit is fully re-pressurised prior to column change
over at pressures over 7 barg.
To carry out the alteration, ensure that the electrical supply is isolated and place the dryer on it's back to gain access to the control base.
Remove the large plate to access the timer board (A). Remove the timer board from the control base (B). Move electric jumper from position 1
to position 2 (C).
