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 MUST be repaired as soon as possible to prevent the damage from

getting bigger. 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 25 .
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.

HEAT TRANSFER SECTION

The inspection procedure is as follows:
1. Shut off fan(s) and pump(s).
2. Remove the eliminators and access doors.
3. Inspect the wet deck surface for

-

obstructions

-

damages

-

corrosion

-

fouling

4. After inspection, install eliminators and access doors and start pump(s) and fan(s).

Remove any obstructions from heat transfer section(s).
Any damages or corroded areas need to be repaired. Call your local BAC Balticare 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 page 25 .
Regular checking of the total aerobic bacteria count (TAB) and maintaining it within acceptable levels are the key

to prevent fouling.

DRIFT ELIMINATORS

The inspection procedure is as follows:
1. With fan(s) and pump(s) running visually check for areas with excessive drift loss.
2. Shut off fan(s) and pump(s) and visually check eliminators for

-

obstructions

-

damages

-

cleanliness

-

proper fit

3. If any of the above problems have been observed, stop fan(s) and pump(s) and remove eliminators.
4. Clean eliminators from debris and foreign matter. Remove dirt and obstructions. Replace damaged or

ineffective eliminators.

5. Install eliminators and ensure they fit tightly with no gaps.
