A.
PRECAUTIONS
1.
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. The MGD-15W-ADV-
02 chiller’s
controller was programmed from the factory for a set point down to 14°F and
the limit control settings have been adjusted as well.
2.
The operating range of the chiller control may be changed to 0°F - 90°F by
adjusting the Minimum Setpoint. Refer to Section 3.10D of this manual for more
information. Contact your local refrigeration contractor or the factory for further
information on limit setting adjustments if the set point will not be 14°F.
