Foreword
The intent of this manual is to serve as a guide for placing your portable chiller in service and operating and maintaining it
properly. This manual is supplemented as required to accommodate any special items that may have been provided for a
specific application. The written information contained in this manual, as well as various drawings, are intended to be
general in nature. The schematics included in this manual are typical only. Actual schematics are included in the electrical
enclosure of the chiller and should be referred to for troubleshooting and servicing of the unit. Additional copies of wiring
diagrams are available upon request. We strive to maintain an accurate record of all equipment during the course of its
useful life. While every effort is made to standardize the design features of these chillers, the various options may make it
necessary to rearrange some of the components; therefore, some of the general drawings in this manual may differ from
your specific unit.
Specific references to current applicable codes, ordinances, and other local laws pertaining to the use and operation of this
equipment are avoided due to their ever-changing nature. There is no substitute for common sense and good operating
practices when placing any mechanical equipment into operation. We encourage all personnel to familiarize themselves
with this manual's contents. Failure to do so may unnecessarily prolong equipment down time.
The chilling equipment uses chemical refrigerants for heat transfer purposes. This chemical is sealed and tested in a
pressurized system containing ASME coded vessels; however, refrigerant gas can be released if there is a system failure.
Refrigerant gas can cause toxic fumes if it is exposed to fire. These units must be placed in a well-ventilated area, especially
if open flames are present.
Failure to follow these instructions could result in a hazardous condition. Consult the unit serial tag for information about
the refrigerant type and charge amount. Customers are advised to immediately implement a refrigerant management
program including a survey of all equipment to document the type and quantity of refrigerant in each machine. All
refrigeration service technicians must be certified by an EPA approved organization. It is recommended that good piping
practices are followed and that the information in this manual is adhered to. We cannot be held responsible for liabilities
created by substandard piping methods and installation practices external to the chiller.
We trust your equipment will have a long and useful life. If you should have any questions, please contact our Customer
Service Department specifying the serial number and model number of the unit as indicated on the nameplate.
Installation
Receiving Inspection
Each unit is skid mounted and boxed or crated to protect it during shipping. If the chiller has a remote air-cooled
condenser, the chiller and the condenser will ship skid mounted and will contain a holding charge of nitrogen. Before
accepting delivery, check the box or crate for visible damage. If damage is evident, it should be properly documented on
the delivery receipt and the box or crate should be immediately removed to allow for detailed inspection of the unit. Check
for broken refrigerant lines, oil leaks, damaged controls, or any other major component torn loose from its mounting point.
Any sign of damage should be recorded and a claim filed immediately with the shipping company. In order to expedite
payment for damages it is important to record and document damage. An excellent way to do this is by taking pictures.
Our Customer Service Department will provide assistance with the preparation and filing of your claims, including arranging
for an estimate and quotation on repairs.
Rigging, Handling, and Locating Equipment
Proper rigging methods must be followed to prevent damage to components. Avoid impact loading caused by sudden
jerking when lifting or lowering the chiller. Use pads where abrasive surface contact is anticipated.
The unit is designed for indoor use. If it is necessary to store the chiller in an unheated area when not in use, be sure that
all water is drained or that an adequate amount of antifreeze is added to prevent freeze-up of the unit. A primary concern
when designing your unit was serviceability, therefore, the chiller should be located in an accessible area.
Electrical Power
All wiring must comply with local codes and the National Electric Code. Minimum circuit ampacities and other unit
electrical data are on the unit nameplate and are shown in the Electrical Specification section at the back of this manual. A
