Kodiak Recirculating Chiller Technical Manual
Manual # 820-0109, Rev. Y, 07/08/10 - 24 - Check Lytron’s website www.Lytron.com
for the most current technical information.
SYSTEM MAINTENANCE AND SERVICE
A qualified service technician must perform all service and maintenance internal to the chiller.
Unqualified individuals conducting service on the chiller could result in damage to the
equipment, personal injury and/or death.
After your Kodiak Recirculating Chiller is up and running, it takes only a small amount of care and maintenance
to keep it running well.
Every installation is unique, and the operating conditions determine how often the equipment should be
inspected and maintenance be performed. The following are some guidelines.
Periodic Inspections
Noise Level
Any abnormal sounds or a substantial increase in noise level since the last weekly inspection may indicate the
following: impending pump, fan or coolant blockage problem. Investigate the cause and perform the necessary
service. Refer to the troubleshooting guide in this manual.
Leakage
If you notice coolant on the floor near the chiller or dripping from the chiller enclosure turn off the chiller.
Disconnect the power cord. Find and repair any leaks immediately.
Coolant Level
Any significant drop in the coolant level should be investigated further. If there is no visible system leak, then
the loss may be due to equipment leakage elsewhere.
Pump / Motor
Some pumps may require lubrication. If the pump needs lubrication, lubricate annually with 20-30 drops of SAE
Oil.
Fan Assembly
No maintenance is required on the fan. Listen for any abnormal sounds.
Condenser Fin
Remove the front grill by sliding it upward, pulling the bottom out and pulling it straight down. For maximum
performance the condenser fin should be free of dust and debris. Use a vacuum cleaner or compressed air to
remove any debris and keep the fin clean.
Water Filter
With a new system the filter quickly accumulates foreign matter introduced during system setup. This can lead
to a decrease in system performance in a short period of time. Inspect the filter cartridge one day after you set
up a new system to ensure the filter is clean and the system runs at maximum capacity. After this initial filter
inspection, check the filter weekly. For replacement filters contact Lytron’s Customer Service at 781-933-7300.
Deionization Package
The cartridge life is a function of the user’s application. Check the water resistively weekly and change the
cartridge as required. For replacement filters contact Lytron’s Customer Service at 781-933-7300.
Low Level Switch
The level switch protects the pump in the event of accidental fluid loss. Since this switch is "passive" during
normal operation, it is advisable to check it every 6 months. Open the tank cover and push down on the switch
to see if the low level alarm is activated.
