During normal operation a solid layer of ice at the top of the tank will not form. However, should such a
layer be formed due to unforeseen and unwanted operational circumstances, the low level alarm can be
activated. In such case melt out the ice completely.
COIL
The coil should be observed when there is no ice on the coil.
1. Inspect the coil for
-
obstructions
-
damages
-
corrosion
-
fouling
2. Remove any obstructions from the coil
Any damages or corroded areas need to be repaired. Call your local BAC representative for assistance.
Regular checking of the total aerobic bacteria count (TAB) and maintaining it within acceptable levels are the key
to prevent fouling.
The coil support is a part of the structure of the tank. In case the coils need to be removed, the tank must be
emptied.
CAUTION
DO NOT remove or loosen bolts from the coil supports when the tank is filled with water.
ICE LOGIC™ ICE QUANTITY CONTROLLER
Check monthly the control sensors for any visual signs of damage.
GLYCOL
Every six months, or at the seasonal start-up, draw a sample of the glycol solution from the system and check the
concentration using a refractometer. If necessary, adjust the concentration using the proper type of industrially
inhibited glycol.
Annually, have your glycol supplier check samples of the glycol solution for the proper level of inhibitors and adjust
if necessary.
