K1, K3 series chillers – Installation and Operation manual
Issue 7.0 Page 11
Caution:
When the flow/pressure is manually increased with the pressure relief valve, the safety
provided by the valve will be effected at higher pressures than standard. For this reason,
please ensure that it is safe for your application to operate at pressures in excess of 50 psi,
even if the pressure setting on the chiller reads lower than this. A blockage in your
application could result in the pressure exceeding the raised safety pressure, and while the
K series chiller is tested to 120 psi, your application may not be safe at this pressure.
We recommend that pressures exceeding 100psi must never be used.
4.0 Maintenance and service requirements
Caution: Failure to carry out service at the specified intervals may permanently damage
your equipment.
Interval Actions
Weekly Check fluid level
Monthly Check the condenser (air intake) is free from obstructions or
accumulations of debris. Cleaning may be achieved with a domestic
vacuum cleaner with brush attachment.*
Annually Change the fluid.
Check for fluid leaks throughout the whole system.
Check the condenser for fouling.
* Caution: Never blow the condenser out with compressed air.
4.1 Status lights and troubleshooting
The status panel on the front of your K1 chiller is fitted with three green lights, configured
such that ‘three greens is good’; i.e. when they are lit, the parameter is operating within
design limits.
If an indicator light is not lit, this indicates an alert situation with the corresponding
parameter, as follows:
