2. Remove any obstructions from the coil
Any damages or corroded areas need to be repaired. Call your local BAC representative for assistance.
Minor fouling can usually be removed chemically or by temporary changes to the water treatment programme.
Contact your water treatment supplier for advice. Major fouling requires cleaning and flushing according to the
"Cleaning procedures" on the facing page
Regular checking of the total aerobic bacteria count (TAB) and maintaining it within acceptable levels are the key
to prevent fouling.
ICE LOGIC™ ICE QUANTITY CONTROLLER
Check monthly the control sensors for any visual signs of damage.
AIR PUMP
The air pump assembly is designed to provide air to the Ice Chiller
®
Thermal Storage Unit for tank water agitation.
The air pump should run as a minimum during the first 3 hours of ice build to ensure a homogenous water
temperature in the tank. For applications with limited cooling requirements during the ice build (< 15% of installed
compressor capacity), the air pump must run continuously during the ice build. To ensure high melt out rates,
continuous air pump operation during melt off is required.
The air blown in the Ice Chiller
®
Unit will entrain in the water piping and can accumulate in the upper part if the
outlet piping is located above the operating water level. In these installations an air vent must be provided at the
highest point of the piping.
The air pump is designed to require little maintenance, but some guidelines should be followed to assure trouble-
free operation.
1. Do not run the blower with air supply line closed or low flow condition. This will cause a temperature rise in the
blower casing. Allow adequate space around the air pump for unobstructed flow of air.
2. Check and clean the air filter once a month and change the filter every 3000 operating hours or at least every
year.
3. The air pump bearings are permanently greased and sealed and require no maintenance.
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.
