Issue 3.2 11
Caution:
Changing the flow/pressure with the pressure relief valve will also change the pre-set
pressure safety set-point. This will move to a lower pressure than the factory setting
when decreasing the flow/pressure, and to a higher pressure when increasing the
flow/pressure.
Caution:
When the flow/pressure is manually increased with the pressure relief valve, the safety
provided by the valve will be affected 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 Kt1 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.
Check the condenser (air intake) is free from obstructions or accumula-
tions of debris. Cleaning may be achieved with a domestic vacuum
cleaner with brush attachment.*
