glycol in hydraulic circuit<br />
unit ON with alarm<br />
“Low Pressure<br />
compressor 1, 2” ˜ ˜ Both circuits have<br />
insufficient refrigerant<br />

Blue Box 55<br />
POSSIBLE CORRECTIVE <strong>AC</strong>TION<br />
Restore correct glycol percentage<br />
Find possible leaks in circuit,<br />
repair, and recharge<br />
Check voltage across the<br />
contactor coil and coil continuity<br />
˜ Fan motor faulty Check and replace if necessary<br />
˜ Insufficient water flow to<br />
evaporator<br />
˜ Incorrect setting of defrost<br />
set-point<br />
˜ Insufficient water flow to<br />
evaporator<br />
Check hydraulic circuit<br />
Check and correct setting if<br />
necessary<br />
Increase water flow to<br />
evaporator and check<br />
temperature rise<br />
