1.1 INTRODUCTION
A. This manual covers portable chillers from 5 to 40 tons (17 to 140 kW) of cooling capacity
usingtheTemptekCFmicroprocessorcontrolinstrumentandxeddisplacementscroll
compressorsanddigitalscrollcompressors.Thestandarduidoperatingtemperature
range for this chiller is 20°F to 80°F for units using R410A refrigerant. Units using other
refrigerantshavedifferentstandardoperatingranges.Unitsoperatingbelow48°Fuid
require the use of a water/propylene glycol to prevent freezing. Customized units may
have different operating ranges. Consult the factory if you have questions about the
operating range of your chiller.
B. The intent of this manual is to serve as a guide in the installation, operation and
maintenance of your chiller. Improper installation can lead to equipment damage
and poor performance. Failure to follow the installation, operation and maintenance
instructions may result in damage to the unit that is not covered under the limited
warranty. This manual is for standard products. The information contained in this manual
is intended to be general in nature. The information is typical only and may not represent
the actual unit purchased.
C. Chemical refrigerants are used in this unit. The refrigerant is sealed and tested in a
pressurized system however a system failure will release it. Refrigerant gas can cause
toxicfumesifexposedtore.Installthisunitinawell-ventilatedareaawayfromopen
ames.Failuretofollowtheseinstructionsmayresultinahazardouscondition.Recover
refrigerant to relieve pressure before opening the system. See nameplate for refrigerant
type. Do not use non-approved refrigerants or refrigerant substitutes.
D. Customers should implement a refrigerant management program to document the type
and quantity of refrigerant in each chiller. All refrigeration service technicians performing
workonthischillermustbelicensedandcertied.
E. WhencallingforassistancefromtheManufacturer’sServiceDepartment,itisimportant
to know the model and serial number of the particular unit. The model number includes
criticalunitinformationwhichishelpfulwhentroubleshootingoperatingdifculties.The
serial number allows the service team to locate manufacturing and testing records which
can have additional information relating to a particular unit.
1.2 SAFETY
A. It is important to become thoroughly familiar with this manual and the operating
characteristics of the unit.
B. Itistheowner’sresponsibilitytoassureproperoperatortraining,installation,operation,
and maintenance of the unit.
C. Observe all warning and safety placards applied to the chiller. Failure to observe all
warnings can result in serious injury or death to the operator and severe mechanical
damage to the unit.
D. Observe all safety precautions during installation, startup and service of this equipment
duetothepresenceofhighvoltageandrefrigerantcharge.Onlyqualiedpersonnel
should install, startup and service this equipment.

E. When working on this equipment, observe precautions in literature and on tags, stickers
and labels located on the equipment. Wear work gloves and safety glasses.
F. Samples of Warning Labels applied to typical chillers.
1. Alerts users to the danger of high
voltage.
2. Alerts user to the danger of the rotating
condenser fans on air condensed units.
3. Alerts user to the danger of belt drive
systems on unit with blowers.
4. This symbol is seen on all chillers to alert user to the
danger of the refrigeration system under pressure.
System should only be serviced by a licensed
technician.
WARNING: This equipment contains hazardous voltages that can cause severe injury or death.
Disconnect and lock out incoming power before installing or servicing the equipment.
WARNING: This equipment contains refrigerant under pressure. Accidental release of refrigerant
under pressure can cause personal injury and or property damage. Exercise care while working
on or around this equipment.
WARNING: Vent all refrigerant relief valves in accordance to ANSI/ASHRAE Standard 15,
Safety Code for Mechanical Refrigeration. This equipment should be located within a well-
ventilated area. Inhalation of refrigerant can be hazardous to your health and the accumulation
of refrigerant within an enclosed space can displace oxygen and cause suffocation

1.3 RECEIVING INSTRUCTIONS
A. Chillers are shipped skid mounted and wrapped in plastic prior to shipment. Check the
overall condition of the equipment prior to accepting delivery.
B. Check for visible damage and document any evident damage on the delivery receipt.
Check the refrigerant gauges to be sure the system charge is intact. See the chart
in section 8.3 for proper pressure readings based on the ambient temperature and
refrigerant type used in the chiller. Shipping damage is the responsibility of the carrier.
C. In order to expedite payment for damages, should they occur, follow proper procedures
and keep detailed records. Take photographs of any suspected damage.
1.4 EFFICIENCY
A. Longtermefciencyofoperationislargelydeterminedbypropermaintenanceofthe
mechanical parts of the unit and the water quality. The Manufacturer recommends

1.5 CLEAN AIR ACT
A. Units manufactured after January 1, 2010 may contain refrigerant HFC-410A, HFC-407C,
HFC-404A or HFC-134A. Most units manufactured prior to January 1, 2010 contain
refrigerant HCFC-22.
B. It is unlawful for any person in the course of maintaining, servicing, repairing, or disposing
of refrigeration equipment to knowingly vent or otherwise dispose of any substance used
as a refrigerant in the manner which permits such substance to enter the atmosphere.
C. Very small releases associated with good faith attempts to recapture, reclaim or
recycle such substance shall not be subject to the prohibition set forth in the preceding
paragraph.
D. Customers should implement a refrigerant management program to document the type
and quantity of refrigerant in each chiller. All refrigeration service technicians performing
workonthischillermustbelicensedandcertied.
E. Vent all refrigerant relief valves in accordance to ANSI/ASHRAE Standard 15.
WARNING: Vent all refrigerant relief valves in accordance to ANSI/ASHRAE Standard 15,
Safety Code for Mechanical Refrigeration. This equipment should be located within a well-
ventilated area. Inhalation of refrigerant can be hazardous to your health and the accumulation
of refrigerant within an enclosed space can displace oxygen and cause suffocation.
