Installation
Coolant Requirements:

Boyd recommends using filtered clean water above 10
o
C as coolant.

If the set point is 10
o
C 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.
