Titan Central Chillers
3. PRECAUTIONS:
The chiller control is programmed from the factory with a setpoint range of 48°
to 70°F. To operate below 48°F, the addition of inhibited propylene glycol and
modification of the limit control settings are required. These adjustments are
done from the chiller controller screen. Diligent monitoring of the water/glycol
solution is mandatory to prevent freezing of the evaporator. Freezing may cause
the evaporator to rupture allowing water and freon to mix which will cause major
damage to the refrigeration system.
R134A and R407C models operating above 70°F and R404A models operating
above 60°F require the addition of a refrigerant crankcase pressure regulating
(CPR) valve. The CPR valve is necessary to lower the temperature of the gas
returning to the compressor so that the compressor is cooled properly. R410A
models may be operated up to 80°F without a CPR valve.
Contact your local refrigeration contractor or the factory for further information.
The operating range of the chiller control may be changed to 10°F - 90°F by
adjusting the Setpoint Lockout (SPL) jumper. Refer to Section 3.3.c.3 of this
manual for more information.

Outputs indicate the state of the chiller's refrigerations system. When
four small dots are shown the refrigeration system is off. When the first
