LX/HD RETROFIT PANELS
The
QUANTUM
™
LX/HD
Control Panels sold under this program are designed to handle standard screw compressor package
design. Compressors are to be electric motor driven only. Other drive lines can be accommodated through Frick
®
Engineering.
Lubrication is accomplished by electric motor or shaft driven oil pumps, or differential pressure lube systems. If the compressor
package does not meet these basic requirements, contact Frick
®
for Engineering assistance. Frick
®
can make the proper changes
for most applications, but there will be an Engineering charge.
In some cases, even though the screw compressor package meets the basic requirements, package modifications and/or control
panel modifications may be required: non-standard sensors, modified piping, additional solenoids and check valves, and additional
relays into the control circuits, etc. This is the case with most vertical separators, screw chiller packages, and other specific-duty
screw compressor packages. Normally, an experienced installer can handle these items in the field. Contact Frick
®
Engineering
for assistance if a problem is encountered.
The
QUANTUM
™
LX/HD
Control Panel will be offered in a “kit” form which will supply the panel, drawings, and the current instal-
lation and operation manual. Pressure transducers, temperature probes, and slide valve indicator potentiometers and assemblies
are optional items and must be ordered separately, if required.
INTRODUCTION
CONVERSION OF SCREW COMPRESSOR UNITS TO
THE FRICK
®
QUANTUM
™
LX/HD
CONTROL PANEL.
These instructions are based on the installer having a fun-
damental knowledge of refrigeration design and installation.
Instructions are for conversion to the standard design unit.
Special package and/or control modifications furnished on
the existing unit will require deviation from these instruc-
tions. Contact Frick
®
if you have any questions, concerns or
problems. Frick
®
does not take responsibility for the suitability
of these instructions, for any nonstandard installation or for
consequential damages resulting from the conversion.
DO NOT INITIATE RETROFIT CONVERSION UNTIL YOU
HAVE COMPLETELY REVIEWED ALL INSTRUCTIONS AND
CHECKED MATERIAL RECEIVED FOR SUITABILITY AND
COMPLETENESS.
Instructions are provided for retrofit conversion from either
RWB Electromechanical or RWB II Microprocessor Control
to
QUANTUM
™
LX/HD
Control. Other screw compressors
not manufactured by Frick
®
can also be converted to the
QUANTUM
™
LX/HD
Control. Frick
®
screw compressor pack-
ages, where the compressor itself was not manufactured by
Frick
®
, are considered to be in this “other manufacturers”
category.
