Page 6: General Information
Min. temperature of fluid: -20°C PURGE REQUIREMENTS The installer of BAC equipment must ensure proper system purging of air prior to operation. Entrained air can obstruct the proper flow of glycol solution, resulting in higher operating pressures than design and reduced thermal storage capacity. -
Page 7: Safety Precautions
At no time this equipment should be operated without all access cover panels and access doors in place. For more information consult your local BAC Balticare representative. ELECTRICAL SAFETY Each motor associated with this equipment should be installed with a lockable disconnect switch located within sight of the equipment. No service work should be performed on or near the motors unless motors are electrically... -

Each system design is unique and variations in the operating modes may occur. If you have any questions about application of the operating sequences listed below, please contact your BAC Balticare representative to review your specific application. - Page 11 ® 3. Turn on the glycol circulating pump(s) to establish flow between the glycol chiller(s) and the ICE CHILLER Unit. 4. Turn on the air agitation blower(s) feeding the ice storage tank. 5. Once glycol flow has been established, turn on the glycol chiller(s). Follow the chiller manufacturer's start-up procedures and safeties.

Page 12: Ice Logic® Ice Quantity Controller
• To increase control flexibility, use 1 additional ICE LOGIC™ Ice Quantity Controller on a 4 coil unit (available as an option). ICE LOGIC® Ice Quantity Controller ® The ice quantity in the ICE CHILLER Unit will be measured by means of a sensor measuring the ice thickness. The measurement is done in steps of 20%: 0, 20, 40, 60, 80 and 100% of the nominal ice storage capacity of the ®... - Page 13 Manual Control The required ice quantity for the next cooling cycle can easily be set from the control panel in steps of 20%. In addition, the minimum ice quantity, before the cooling equipment should start again, can be set from the minimum % ice knob.
- Page 14 Remote Control with 4-20 mA Output Signal (Option) Instead of 6 output signals for remote control, an analog output signal of 4-20 mA can be generated using contacts 28/29. The customer must provide a 24 VDC supply voltage with a loop resistance of max. 600 Ohms (see R). In that case contacts 10 to 21 are no longer available.

Page 15: Water Care
To control biological growth, a biocide may be needed on a periodic basis to prevent the growth of corrosive bacteria. In general, BAC recommends the following guidelines. (See Table below). -
Page 16: Passivation
Passivation When new systems are first commissioned, special measures should be taken to ensure that galvanized steel surfaces are properly passivated to provide maximum protection from corrosion. Passivation is the formation of a protective, passive, oxide layer on galvanized steel surfaces. To ensure that galvanized steel surfaces are passivated, for the first 6-8 weeks of operation, the pH of the tank water should be maintained between 7.0 and 8.2 and calcium hardness maintained between 100 and 300 mg/l (as CaCO... -
Page 17: Cold Weather Operations
TSU-C-D COLD WEATHER OPERATIONS About Cold Weather Operation BAC equipment can be operated in subfreezing ambient conditions provided the proper measures are taken: 1. Insulation of piping. 2. Protection against coil freezing. 3. Elimination of ice due to sub-freezing ambient. -
Page 18: Ice Due To Sub-Freezing Ambients
Ice due to Sub-Freezing Ambients ® ICE CHILLER tanks that have been exposed to severe or sustained subfreezing ambient temperatures, should be checked before initiating an ice build cycle. Ice created by subfreezing ambient temperatures which accumulates at the top of the tank and around the walls must be melted out before initiating a build cycle. This ice can prevent normal water displacement during the build cycle, possibly leading to physical damage to the coil and tank walls. -
Page 19: Maintenance Procedure
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. - Page 20 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.

Page 21: Cleaning Procedures
6 hours. Higher chlorine levels for a shorter period are possible, but require a higher level of corrosion protection than galvanized steel only. Consult your BAC Balticare representative for further information. - Page 22 Chlorinated water should be de-chlorinated before draining and after disinfection the system must be thoroughly flushed through with clean water. A proper regularly monitored biocide programme reduces the need for cleaning and disinfection actions significantly. W W W . B A L T I M O R E A I R C O I L . E U...
