HD RETROFIT pANELS
The
QUANTUM
™
HD
control panels sold under this program
are designed to handle standard screw compressor pack-
age piping and instrument 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. Additional engineering and
drawing charges will be quoted. Examples of standard
piping and instrument designs for both Frick and other
manufacturer's designs are shown on page 3.
In some cases, even though the screw compressor pack-
age 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 as-
sistance if a problem is encountered.
The
QUANTUM
™
HD
control panel will be offered in a “kit”
form which will supply the panel, drawings, and the current
installation, operation, and maintenance manuals. Standard
pressure and temperature sensor kit includes four pressure
and four temperature sensors. Pressure sensor connections
are 1/4" MPT.
The standard temperature probe used with the Vilter
®
Single Screw is 1/4" MPT and threads into the existing
thermo-well. Additional pressure transducers and tempera-
ture probes are available as optional items. Temperature
probes are available in 3/4" and 1/2" MPT with thermo-wells
or 1/4" without the thermo-well.
See page 3 of the Order Entry Data Sheet (Publication
090.100A-P) to select these and other options.
INTRODUCTION
CONVERSION OF SCREW COMpRESSOR UNITS TO
THE FRICK
®
QUANTUM
™
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 instructions.
Contact Frick
®
if you have any questions, concerns or prob-
lems. Frick
®
does not take responsibility for the suitability
of these instructions, for any nonstandard installation or for
consequential damages resulting from the conversion.
NOTICE
Do not initiate retrofit conversion until you have
completely reviewed all instructions and checked
material received for suitability and completeness.
Material supplied with this Frick
®
retrofit kit:
A.
A complete
QUANTUM
™
HD
control panel.
B.
Operation, Maintenance and Retrofit Conversion
manuals.
C.
Four ICTD Temperature Probes 1/4" MPT (less well).
D.
Three 0-500 PSIA Pressure Transducers 1/4" MPT.
E.
One 0-200 PSIA Pressure Transducer 1/4" MPT.
Each sensor comes with a 24' section of the proper shielded
cable with DIN connector to plug onto the sensor.
A pressure transducer manifold block, with mounting brackets
and service valves for the pressure transducers, is available
as an option. With this option, the cables on the transduc-
ers are 8'.
NOTICE
Older gear driven capacity and volume slide actuators
must be replaced with the optical style actuators
shown in Figure 4 before retrofitting.
MATERIAL TO BE SUppLIED BY INSTALLER AS REQUIRED
•
Pressure tubing and fittings (1/4 inch stainless steel)
•
Pipe, fittings, and adaptors
•
Electrical conduit, fittings, and solenoids
•
Wire
•
Current transformer in the compressor motor starter,
control transformer, and any motor starter compo-
nents or modifications.
•
Labor and tools required to complete installation and
start-up.
