Kodiak Recirculating Chiller Technical Manual
Manual # 820-0109, Rev. Y, 07/08/10 - 17 - Check Lytron’s website www.Lytron.com
for the most current technical information.
INSTALLATION REQUIREMENTS
Coolant Requirements
Lytron recommends using filtered clean water above 10°C/50°F as coolant.
If the set point is 10°C/50°F 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.
Do not use automotive anti-freeze in the chiller. The rust inhibitors in the automotive type
may cause premature failure of the pump seals. Use of automotive anti-freeze in a Lytron chiller will void
the warranty.
Avoid using water with a high mineral content.
If the coolant is exposed to sunlight add an algaecide to control organic growth in lines.
Electrical Requirements (for units 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 an 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 SJT
3 conductor 12 AWG minimum power cord.
Selecting Chiller Location
Do not operate or store Kodiak chillers outside. These systems are not intended for outdoor
use.
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 as
they are not capable of high head pressures. Coolant lines are best run at or near the same level as the cooling
system. Once the chiller is in position lock the casters.
Airflow 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" (456 mm).
The top clearance must be at least 6" (152 mm). 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.
Before moving 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 10C (50F).
