Foreword
The central chiller contains on or more refrigeration
circuits intended to chiller or cool a process fluid. As
an option, a process fluid reservoir and pumping
system is available to create a complete packaged
chiller system.
The intent of this manual is to serve as a guide for
placing our central chiller in service and operating
and maintaining it properly. Improper installation
can lead to poor equipment performance or severe
equipment damage. Failure to follow the installation
instructions may result in damage not covered by
your warranty. It is extremely important that a
qualified refrigeration installation contractor perform
all installation line sizing and piping. Please supply
these instructions to your authorized refrigeration
contractor. This manual is for our standard product
line with supplements as required to accommodate
any special items provided for a specific application.
The written information contained in this manual, as
well as various drawings, are intended to be general
in nature. Unit specific drawings are included with
the equipment for troubleshooting and servicing of
the unit. Additional copies of drawings are available
upon request. We strive to maintain an accurate
record of all equipment during the course of its
useful life.
Due to the ever-changing nature of applicable
codes, ordinances, and other local laws pertaining to
the use and operation of this equipment we do not
reference them in this manual. 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 chiller uses chemical refrigerants for heat
transfer purposes. This chemical is sealed and tested
in a pressurized system containing ASME coded
vessels; however, a system failure will release it.
Refrigerant gas can cause toxic fumes if exposed to
fire. Place these units in a well-ventilated area,
especially if open flames are present.
Failure to follow these instructions could result in a
hazardous condition. The standard refrigerant used
in these units is a hydro fluorocarbon (HFC) trade
named R-410A. We strongly recommend a
refrigerant management program be implemented
which includes a survey of all equipment to
document the type and quantity of refrigerant in
each machine. In addition, we recommend only
licensed and EPA certified service technicians work
on our refrigeration circuits. Follow good piping
practices and the information in this manual to
ensure successful installation and operation of this
equipment. We are not 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
the Conair Service Department specifying the serial
number and model number of the unit as indicated
on the nameplate.

Only qualified personnel should install, start-up, and
service this equipment. When working on this
equipment, observe precautions in literature, and on
tags, stickers, and labels located on the equipment.
WARNING: Any use or misuse of this equipment
outside of the design intent may cause injury or
harm.
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.
WARNING: This equipment contains hazardous
voltages that can cause severe injury or death.
WARNING: This equipment contains refrigerant
under pressure. Accidental release of refrigerant
under pressure can cause personal injury and or
property damage.
WARNING: This equipment may contain fan
blades or other sharp edges. Make sure all fan
guards and other protective shields are securely
in place.
WARNING: The exposed surfaces of motors,
refrigerant piping, and other fluid circuit
components can be very hot and can cause burns
if touched with unprotected hands.
CAUTION: Disconnect and lock out incoming
power before installing, servicing, or
maintaining the equipment. Connecting power to
the main terminal block energizes the entire
electric circuitry of the unit. A power supply
provides 24 VDC control power. Electric power at
the main disconnect should be shut off before
opening access panels for repair or maintenance.
CAUTION: Wear eye protection when installing,
maintaining, or repairing the equipment to
protect against any sparks, debris, or fluid leaks.
CAUTION: The chiller will exceed 70 dBA sound
pressure at 1 meter distance and 1 meter
elevation when operating. Wear ear protection
as required for personnel comfort when
operating or working in close proximity to the
chiller.
CAUTION: Wear protective gloves when
installing, maintaining, or repairing the
equipment to protect against any sparks, debris,
or fluid leaks.

Pre-Installation
Receiving Inspection
When the unit arrives, verify it is the correct unit by
comparing the information that appears on the unit
nameplate with that which appears on the order
acknowledgement and shipping papers. Inspect the
equipment condition for any visible damage and
verify all items shown on the bill of lading are
present. If damage is evident, properly document it
on the delivery receipt and clearly mark any item
with damage as “unit damage” and notify the carrier.
In addition, make note of the specific damage and
notify Conair’s Service Department.
Shipping damage is the responsibility of the carrier.
To protect against possible loss due to damage
incurred during shipping and to expedite payment
for damages, it is important to follow proper
procedures and keep records. Photographs of
damaged equipment are excellent documentation
for your records.
Start unpacking the unit, inspect for concealed
damages, and take photos of any damages found.
Once received, equipment owners have the
responsibility to provide reasonable evidence that
the damage did not occur after delivery. Photos of
the equipment damage while the equipment is still
partially packed will help in this regard. Refrigerant
lines can be susceptible to damage in transit. Check
for broken lines, oil leaks, damaged controls, or any
other major component torn loose from its
mounting point.
Record any signs of concealed damage and file a
shipping damage claim immediately with the
shipping company. Most carriers require concealed
damages be reported within 15 days of receipt of
the equipment. In addition to notifying the carrier,
notify Conair’s Service Department.
Water-cooled chillers ship with a full refrigerant
charge while remote condenser chillers ship with a
nitrogen holding charge. Remote air-cooled
condensers ship separately with a 350-psi dry
nitrogen gas charge. Check the remote condenser
for signs of leaks prior to rigging. This will ensure no
coil damage has occurred after the unit left the
factory. The condenser ships with the legs removed.
Mount the legs to the condenser using the provided
nuts, bolts, and washers.
Unit Storage
If the chiller is stored prior to installation, it is
important to protect it from damage. Blow out any
water or fluid from the evaporator and water-cooled
condenser circuits to protect the unit from damage
from freezing. Close any open refrigerant valves.
Cover the equipment to keep dirt and debris from
accumulating on it. Units charged with refrigerant
should not be stored in areas warmer than
145°F (62.8°C).

Installation - Chiller
Mechanical
Unit Location
The chiller is available in many different
configurations to meet various environments. Please
refer to the proposal and order acknowledgement
for this equipment to verify the specific
environmental design conditions for your chiller.
Allow a minimum of 48 inches (1219mm) of
clearance between the remote condenser and any
walls or obstructions. For installations with multiple
condensers, allow a minimum of 96 inches (2438mm)
between condensers placed side-by-side or 48
inches (1219mm) for condensers placed end-to-end.
In all cases, install the equipment on a rigid surface
suitable to support the full operating weight of the
unit. Level all equipment to ensure proper operation.
When installed the equipment must be level within
¼ inch over its length and width.
Serviceability is an important factor to consider when
deciding on the location of the chiller. Do not
compromise this feature by locating it in an
inaccessible area. When locating the chiller it is
important to consider accessibility to the
components to allow for proper maintenance and
servicing of the unit. In general, allow a minimum of
36 inches (914mm) of clearance around all sides and
above the unit. There should be no piping or conduit
located over the unit. This will ensure easy access
with an overhead crane or lift for heavier
components should they need to be replaced or
serviced.
Proper ventilation is another important
consideration when locating the unit. Locate the unit
is an area that will not rise above 110°F (43.3°C).
In addition, ensure the condenser and evaporator
refrigerant pressure relief valves can vent in
accordance with all local and national codes.
Rigging
The chiller has a structural steel frame with forklift
slots to facilitate easy movement and positioning.
Follow proper rigging methods to prevent damage
to components. Avoid impact loading caused by
sudden jerking when lifting or lowering the chiller.
Use pads where abrasive surface contact may occur.
Use the frame supporting the unit for positioning it
with a crane or a forklift.
Chilled Water Piping
Proper insulation of chilled water piping is crucial to
prevent condensation. The formation of
condensation on chiller water piping, the state
change of the water from gas to liquid, adds a
substantial heat load to the system and becomes an
additional burden for the chiller.
The importance of properly sized piping between
the chiller and process cannot be overemphasized.
Reference the current edition of the ASHRAE
Fundamentals Handbook or other suitable design
guide for proper pipe sizing. In general, run full size
piping out to the process and then reduce the pipe
size to match the connections on the process
equipment. One of the most common causes of
unsatisfactory chiller performance is poor piping
system design. Avoid long lengths of hoses, quick
disconnect fittings, and manifolds wherever possible
as they offer high resistance to water flow. When
manifolds are required, install them as close to the
use point as possible. Provide flow-balancing valves
at each machine to assure adequate water
distribution in the entire system.
Condenser Water Piping
(Water-Cooled Condenser Chillers Only)
The performance of a condenser is dependent on
maintaining the proper flow and temperature of
water through the heat exchanger. Insufficient water
flow or high condenser water supply temperature
will result in the reduction of cooling capacity of the
chiller. Extreme conditions will eventually result in
the chiller shutting down due to high refrigerant
pressure. Allowing the condenser to plug up from
contaminants in the condenser water stream
adversely affects performance. In order to reduce
maintenance costs and chiller downtime, a water
treatment program is highly recommended for the
condenser cooling water. Contact our Customer
Service Department for assistance in the proper
procedure for cleaning out any plugged condenser.

The nominal chiller design is for 85°F (38.6°C)
condenser cooling water supply. Under normal
operation under full load there will be about a 10°F
(4.5°C) rise through the condenser resulting in 95°F
(43.1°C) exiting water temperature from the
condenser. To ensure proper water flow through the
condenser, the condenser water pump should
provide at least 25 psi (1.7 bar).
Each condenser has a two-way condenser water-
regulating valve. Under varying loads and condenser
inlet water temperatures the amount of cooling
water needed varies. The condenser water-
regulating valve controls the amount of water
allowed to pass through the condenser in order to
maintain proper refrigeration pressures in the circuit.
To prevent damage to the condenser or regulating
valve, the condenser water pressure should not
exceed 150 psig (10.3 bar). The condenser water-
regulating valve controls the condenser water flow in
order to maintain the pressure set point. The chiller
load, condenser-water inlet temperature, and
pressure set point determine the actual flow.
Water Pressure Gauges
It is highly recommended to install pressure gauges
or taps in the inlet and outlet of both the condenser
and evaporator chilled water piping. The ability to
read the pressure drop across the chiller is important
and will aid in preventive maintenance and in
troubleshooting the chiller performance.
Master Temperature Sensor
This section only applies to installations where
multiple chillers are in a common system where one
chiller will be the master with the other chillers
serving as slaves. In those situations, a field-installed
master fluid-temperature sensor is required to be
field installed in the common chilled water supply
and return piping. The sensor ships loose from the
factory. The supply sensor should be installed
downstream of all individual chilled water supply
streams. Position the sensor to read the mixed
supply temperature. The supply sensor will normally
be the control sensor for the chilled water set point
and will determine the loading/unloading of the
compressors of the system.
Mount the sensor in a ½” NPT coupling in a
minimum pipe size of 3”. The probe sheath is ¼” OD
x 3” in length and is equipped with a ½” NPT male
fitting for direct mounting in a coupling. The sensor
is to be direct immersion for the most accurate
reading and quickest response time. If direct
immersion mounting is not possible, mount the
sensor inside a thermowell to aid in maintenance
and or repair of the sensor if opening of the process
piping is not possible. Use a suitable heat transfer
compound with a thermowell. The sensor is
equipped with a NEMA-4 sensor head with an
integral temperature transmitter. Wiring must be
field provided from the sensor head to the chiller
electrical enclosure and landed at the designated
terminal blocks within the enclosure. Please see the
chiller electrical schematic provided for further
detail.
