MAINTENANCE PROCEDURE
Inspections and Corrective Actions
GENERAL CONDITION OF THE EQUIPMENT
The inspection should focus on following areas:
•
damage of corrosion protection
• signs of scale formation or corrosion
• accumulation of dirt and debris
• presence of biofilms
Smaller damages of the corrosion protection can be repaired. For BALTIBOND
®
hybrid coating use kit (part
number RK1057). Larger damages should be reported to the local BAC Balticare representative.
If there is evidence of scale formation (more than 0,1 mm) or corrosion, water treatment regime must be checked
and adjusted by the supplier.
Any dirt and debris need to be removed following the "Cleaning Procedures" on page 21
If there is evidence of biofilms the system, including piping should be drained, flushed and cleaned of slimes and
other organic contamination. Refill system with water and apply biocide shock treatment. Check pH value and
functionality of ongoing biocide treatment.
ICE CHILLER® TANK
All ICE CHILLER
®
Thermal Storage Units are provided with sectional insulated tank covers, which, when kept in
place, will minimize the accumulation of trash or debris in the tank.
However, an ICE CHILLER
®
unit installed outdoors may be susceptible to dust infiltration. Therefore, it is
necessary to inspect the tank regularly to determine whether or not it needs to be cleaned. To clean the tank, drain
it and flush with fresh water.
ICE CHILLER® WATER LEVEL
On a monthly basis and at seasonal start-up, inspect the water level in the ICE CHILLER
®
tank. To properly check
the water level in the tank, the ice must be completely melted .
The water level in the ICE CHILLER
®
tank should be maintained 25 mm above the height of the coil (no ice on
coil). As ice is built on the ICE CHILLER
®
coil, the level of the water in the tank will rise slightly.
Therefore, the level of water should be observed at its lowest point, when there is no ice on the coil. If the tank
level drops to less than 25 mm above the height of the coil, use the make-up connection provided (see certified
print) to bring the water level in the tank up to the recommended operating level.
COIL
The coil should be observed when there is no ice on the coil.
1. Inspect the coil for
- obstructions
