Before Servicing

•Servicing the electrical control box exposes you to high voltage. To avoid electric shock, turn off power at the main circuit breaker before opening the enclosure.

•All electrical wiring must be done by a qualiﬁed electrician and comply with all local codes and regulations.

•Do not substitute or modify system components as this may impair intrinsic safety.

NOTICE

To avoid damaging the circuit boards when servicing the control box, wear Part No. 112190 grounding strap on your wrist and ground appropriately.

To avoid electrical component damage, remove all system power before plugging any connectors.

1.Flush the system as explained in your PD2K Operation Manual if service time may exceed pot life time. Follow the Pressure Relief Procedure, page 35 before servicing ﬂuid components.

2.Close the main air shutoff valve on the air supply line.

3.Shut off the power switch (P) at the electrical control box.

4.If servicing the electrical control box, shut off power at the main circuit breaker before opening the enclosure.
