1. Introduction
This Instrument must be connected to an electrical
circuit which is protected by a Ground Fault Circuit
Interrupter (GFCI) or other leakage current protection
device. The protection device must be tested
periodically for proper operation.
When the Instrument is used in conjunction with other
mains powered equipment, the use of the potential
equalizer conductor is recommended between the
equipment and the Instrument equipotential equalizer
busbars. (Possible hazards may arise which may cause
the allowable leakage current to be exceeded.)
Whenever a mains circuit is serviced or replaced, check
the Instrument leakage current per local code.
Hard power off or disconnect cord before removing
protective panels, soldering, replacing components, or
replacing printed circuit boards.
Do not perform internal service or adjustment of this
Instrument unless another person capable of rendering
first aid and resuscitation is present.
High voltage may be present where the power cable
enters the power entry assembly.
Use care when servicing the Instrument with power on
or the Instrument plugged in. Dangerous voltages exist
at several points in the Instrument. To avoid personal
injury, do not touch exposed connections and
components while power is applied.
Before performing any maintenance on the hydraulic
system, turn off the power and the water.
Fuses should be replaced only by the same rating and
only by a qualified service technician. Check for cause
of the fuse failure.
1.4.2.4 OLHDF
For proper operation of the system and rinsing of the
purge valves, Instruments with the On-Line HDF
hardware must be customized for On-Line HDF.
1.4.2.5 Biohazard
Care should be taken when handling blood
contaminated components to prevent contamination of
personnel or other devices.
