Introduction
This manual provides installation, setup and troubleshooting information for the MicroTech controller
provided on McQuay reciprocating compressor chillers. Please refer to unit installation manuals for unit
application information as well as water and refrigerant piping details. All operating descriptions contained in
this manual are based on MicroTech controller software version RCPXX02G. Chiller operating characteristics
and menu selections may vary with other versions of controller software. Contact McQuayService for
software update information.
CAUTION
This equipment generates, uses and can radiate radio frequency energy and if not installed
and used in accordance with the instructions manual, may cause interference to radio
communications. It has been tested and found to comply with the limits for a class A digital
device, pursuant to part 15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment.
Operation of this equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own expense.
McQuay International disclaims any liability resulting from any interference or for the
correction thereof.
CAUTION
The McQuay MicroTech control panel contains static sensitive components. A static
discharge while handling electronic circuit boards may cause damage to the components.
To prevent such damage during service involving board replacement, McQuay recommends
discharging any static electrical charge by touching the bare metal inside the panel before
performing any service work.
CAUTION
Excessive moisture in the control panel can cause hazardous working conditions and
improper equipment operation.
When servicing equipment during rainy weather conditions, the electrical devices and
MicroTech components housed in the main control panel must be protected.
The MicroTech controller is designed to operate within an ambient temperature range of -40 to 149°F and a
maximum relative humidity of 95% (non-condensing).
