General Information
Chiller System Description
Your chiller consists of a refrigeration system, a coolant loop, associated controls and
plumbing. The pump draws coolant from the internal reservoir and pumps it out to cool your
equipment, and then the coolant flows back to the chiller. It flows through the evaporator,
where the heat is removed, and then flows back into to the reservoir.
Coolant Loop (flow control)
Kodiak chillers are designed to operate with continuous coolant flow through a closed loop.
This loop contains the system pump, temperature sensor, reservoir, internal and external
plumbing lines and fittings, and the external heat load. The external plumbing and the heat
loads are provided by the end user and are generally unique to the user’s process and/or
location.
****CAUTION****
Do not put valves in the system that can stop flow while the chiller is operating.
Refrigeration System and Hot Gas Bypass
The chiller uses a standard refrigeration system to keep the coolant at the process temperature
set point. The compressor compresses the refrigerant vapor (gas), which then passes through
the condenser where it is cooled and turns to a liquid. The refrigerant in its liquid state then
passes through the evaporator. The coolant also flows into the evaporator, through passages
separated by thin layers of metal from the refrigerant. The refrigerant evaporates, drawing heat
from the coolant. The refrigerant vapor returns to the compressor and continues the cycle.

Many refrigeration systems, such as those used in household refrigerators, control the
temperature by turning the compressor on and off. This is a simple, inexpensive method of
controlling the cooling, but its temperature control is not precise and the frequent on-off cycles
cause wear on the compressor motor.
Boyd’s recirculating chillers use a better method for controlling the cooling rate: a hot-gas
bypass system. This employs a liquid line solenoid valve and a hot-gas bypass valve to meter
the refrigerant flow through the evaporator when refrigeration is needed. When the coolant
reaches its set point temperature, the liquid line solenoid valve closes, causing the hot-gas
valve to open. The hot-gas valve lets hot-gas from the compressor discharge into the
evaporator inlet, adjusting the temperature in the evaporator to maintain the correct coolant
temperature. When refrigeration is needed, the liquid line solenoid valve opens, the hot-gas
valve closes and the cycle starts again.
This hot gas bypass control method provides precise temperature control. It also minimizes
wear on the compressor motor, since the compressor runs continuously and does not
experience the stress of repeated cycling.

Optional System Features
Deionization Package:
The Deionization Package consists of a factory-installed deionization cartridge. The
deionization cartridge requires replacement only when the mixed bed is depleted. For
replacement cartridges, Call Boyd’s Customer Service at 781-933-7300. This package is
offered for deionized water applications where the resistance of the water does not exceed 1
megohm-cm, and where the use of brass and copper fittings is acceptable. The deionization
package is not recommended with centrifugal pumps.
Coolant Water Filter:
This factory installed water filter removes particulate from the coolant water. The water filter is
not recommended with centrifugal pumps. For replacement filters, call Boyd’s Customer
Service at 781-933-7300.
Heater Package RC011, RC022, RC030, RC045:
The heater package is for applications requiring coolant temperature well above ambient
temperature. This package is a single set point type. The heater is activated when the water
temperature is 3F below setpoint.
*NOTE: The heater option is not intended to provide tight temperature control, but to bring
coolant temperature up to an application's requirement.
****WARNING****
If your unit was not built with the heater package, do not attempt to retrofit it. If you do,
severe damage will occur to the unit, personal injury may result, and the warranty will be
voided.
High Purity Plumbing:
This option is intended for use with deionized water. Only stainless steel and/or plastic
components and a nickel-brazed heat exchanger come in contact with the coolant. You must
specify this option before you purchase a chiller; it is not field retro-fittable.
External Manually Adjustable Flow Valve:
This option is a valve plumbed between the supply and the return of the chiller. It allows you
to manually adjust the flow rate. To be sure your equipment is receiving
enough flow, install a flow meter at the outlet from your equipment.
External Pressure Relief Valve:
This option is for applications requiring reduced pressure. This kit contains a Pressure Relief
Valve, 2 Tees, Hose Clamps and Plumbing Instructions.

Installation
Coolant Requirements:
Boyd recommends using filtered clean water above 10oC as coolant.
If the set point is 10oC or below, a freezing point depressant, such as ethylene glycol, is
required. This unit is equipped with a low flow switch. This feature will shut the chiller down
during a low flow situation to prevent freezing.
Avoid using water with a high mineral content.
Standard RC units may not be compatible with deionized water. Consult Boyd Application
Engineering for deionized water applications.
If the coolant is exposed to sunlight add an algicide to control organic growth in lines.
****CAUTION****
Positive displacement pumps are susceptible to damage from abrasive materials in the coolant.
To reduce risk of damage, a factory-installed water filter is recommended.
Electrical Requirements (for unit without heater option)
Refer to the Specification section and to the product ID label on the rear of the chiller for the
specific electrical requirements of your unit. The chiller power module is configured with a
standard international IEC320/C20 inlet. To safely operate the chiller, use a SJT cord set with
an IEC 320/C19 receptacle and an inlet plug that is compatible to the local power grid and the
power requirements of the chiller. All Kodiak chillers should use CSJT 3 conductor 12 awg
minimum power cord.
****WARNING****
It is the user’s responsibility to provide a proper ground connection.
Selecting Chiller Location
To minimize the heat gain and pressure drop through the connecting hoses, the chiller unit
should be located as close as possible to the heat load (user equipment). This is more important
for units with centrifugal pumps. Coolant lines are best run at or near the same level as the
cooling system. Once the chiller is in position lock the casters.
Air flow is critical to optimize performance of the chiller. The front and one side or the back
of the unit MUST be kept clear and unobstructed. The remaining two sides or back must have
minimum clearance of 18". The top clearance must be at least 6". Ensure that the hot air
exiting the chiller does not recirculate into the inlet openings. The front of the unit must have a
free supply of ambient-temperature air.

KodiakRecirculating Chiller Technical Manual
Manual# 820-0043 Rev N, 11/25/2019
17
NOTE:
The circuit breaker located on the rear of the unit must be kept clear and easily
accessible.
To move the chiller, cap all ports to prevent any coolant leakage. Unlock the casters and move to new
location. Once in the new location lock the casters. To prevent freezing during storage drain water if
the chiller is located in an area below (10C 50F).
Plumbing the Coolant Lines
The coolant ports are located on the rear of the system and are labeled with the Supply
and Return symbols.
To minimize the pressure loss in the coolant lines, use the largest practical diameter tubing. If
substantial lengths of cooling lines are required, they should be pre-filled with coolant before
connecting them to the chiller.
To minimize heat gain, all lines should be as short as possible. Keep them away from heat
sources such as radiators and hot water pipes. Lines that cannot be routed away from heat
sources should be protected with thermal insulation, preferably at least 1/2" (12.7mm).
Flexible tubing, should be of heavy wall or reinforced construction. All tubing should be rated
to withstand 125 psig at 186oF (30o C). Make sure all tubing connections are secured and leak-
tight. Also, whenever possible use opaque lines to prevent algae growth during prolonged non-
operating periods.
****CAUTION****
Do not connect the SUPPLY or RETURN fitting to your building water supply or any
pressurized source.
Installation Procedure
To connect the fluid lines to the chiller and user equipment follow these steps:
1. Remove the plastic caps covering the supply and return ports on the rear panel of the unit.
2. Attach coolant lines to the supply and return ports on the rear panel.
Supply port: chilled coolant goes out to user equipment
Return port: hot coolant returns from user equipment

3. Refer to the table below for the fitting sizes required for the your unit.
Model# Fitting Size
RC006, RC011, RC022 3/8" FNPT
RC030, RC045 1/2" FNPT
Note: Fittings should either be brass, stainless steel or plastic. Never use steel or cast iron fittings, as
the corrosion will damage the chiller. For chillers with deionization cartridges or high purity
plumbing Boyd recommends the use of either stainless steel or nylon fittings.
4.Remove water filler cover on top of the unit to access the reservoir.
5.Fill the reservoir. Use the reservoir sight tube on the front of the unit to see the coolant level
in the tank as you are filling. Be sure to allow for the volume of coolant needed to fill the
cooling lines between the chiller and the equipment, if they were not filled with coolant before
installation.
6. Centrifugal Pumps must be primed before operation. To prime pumps, disconnect supply line
from rear of chiller, allow air to vent and out of pump head and reconnect line.
For Water Cooled Chillers
7. Connect facility water to connections labeled "City Water In" and "City Water Out".
Minimum flow rate of facility water is shown on page 14. Facility water flow must be started
before chiller is turned on.
****CAUTION****
Standard RC units may not be compatible with deionized water. Consult Boyd Application

Connect a 3-conductor SJT type power cord with an IEC 320/C19 receptacle to the inlet power to the
module on the rear of the unit and to an appropriate AC power source. All chillers should use a 12
gauge power cord.
****WARNING****
Be sure to provide a proper ground connection.

Startup Procedure
1. Turn "ON" the circuit breaker on the rear of the unit. The controller will go through a diagnostic
test. Turn on the chiller unit using the ( I ) key located on the Keypad Display panel. The
controller displays "OFF" for 8 seconds. The delay prevents rapid cycling of the compressor using
the "ON" and "OFF" switch.
****IMPORTANT****
If you have optional controller package 2 or 3, the fault shutoff may prevent the chiller from operating.
If you turn on the unit and it does not operate, disable the fault shutoff. Then turn on the chiller. After
the chiller is operating and the coolant reaches its setpoint temperature, you can enable the fault
shutoff.
2. Set the temperature setpoint using the controls on the keypad display as follows:
Press the “SET” key once to display the current coolant temperature set point.
Press the “UP” or “DOWN” arrow key until the desired coolant temperature setpoint
appears on the LED display.
Press the “SET” key again to accept the setpoint and return to normal operation.
3. Operate the chiller for a short time and then check the coolant level in the reservoir. If the level
drops, add more coolant.
4. Check all fittings and hoses for fluid leaks. If a leak exists, turn chiller off, disconnect power and
take necessary action to repair the leak.
****IMPORTANT****
Do not operate chiller until leak has been repaired.
