GENERAL INFORMATION
About Engineering and Application Practices
This bulletin only refers to the assembly of the unit. To ensure a proper operation, a correct integration of the unit in
the overall installation is mandatory. For good engineering and application practices on layout, levelling,
connecting pipework, etc., please refer to our website: http://www.baltimoreaircoil.eu/knowledge-
center/application-information.
Shipping
BAC equipment is factory assembled to assure uniform quality and minimum field assembly.
For the dimensions and weights of a specific unit or section, refer to the certified drawing.
Inspection Before Rigging
When the unit is delivered to the jobsite, it should be checked thoroughly to ensure all required items have been
received and are free of any shipping damage prior to signing the bill of lading.
The following parts should be inspected:
• Exterior panels and covers
• Ice coils
• Sight tube and Ice Logic Ice Quantity controller (optional)
• Air pump
• Caulking material
The air pump and caulking material are shipped loose in a separate crate.
If shipping damage has occurred, this should be clearly indicated on the CMR.
Unit Weights
Before rigging any BAC equipment, the weight of each section should be verified on the unit certified drawing.
Refer to the Rigging section for weight values.
These weights are approximate only and should be confirmed by weighing before lifting when available
hoisting capacity provides little margin for safety.

Caution
BEFORE AN ACTUAL LIFT IS UNDERTAKEN, ENSURE NO WATER, SNOW, ICE OR DEBRIS
HAS COLLECTED IN THE UNIT. SUCH ACCUMULATIONS WILL ADD SUBSTANTIALLY TO THE
EQUIPMENT'S LIFTING WEIGHT.
Leveling
The unit must be level for proper operation and ease of piping.
When the unit is installed on a concrete slap, this one should have a levelness or maximum slope of 3mm per
3meter and the flatness should be no more than 4mm over a 2m span.
Support beams must also be level as shims should not be used between pan and support beams to level the unit.
Connecting Pipework
All piping external to BAC cooling equipment must be supported separately.
In case the equipment is installed on vibration rails or springs, the piping must contain compensators to eliminate
vibrations carried through the external pipework.
All connections in the external pipework (installed by others) must be leak free and tested accordingly.
Suction pipe sizing should be done according to good practice, which may for larger flows require larger pipe
diameters than the outlet connection. In such cases adapter pieces need to be installed.
Coil Connections
Coils of BAC Ice thermal Storage Units are filled with a low pressure inert gas at the factory before shipping, to
ensure an optimal internal corrosion protection. It is recommended to check the overpressure every six months
(connect a manometer to the valve).
On site, the pressure needs to be released from the coil. Remove the plug first before opening the pressure relieve
valve.
Next the connections need to be cut at 1cm from the end. Make sure to protect the unit against sparks from the
cutting process with a suitable material.
In case of threaded connections, clean up the thread prior to connecting it to the pipework.
Non-threaded connections must be bevelled on site before they can be welded.

RIGGING
General Notes
1. To simplify rigging and installation, units are shipped in one piece, so only one lift is required. It is important to
follow the guidelines listed below when rigging these units.
2. Lifting devices have been provided for short lifts and final positioning. The table "Approximate Shipping weights
& Dimensions" shows the location of the lifting devices for each tank size.
3. Lifting and transportation of the equipment by means of lift trucks is not permitted, as this may result in serious
damage of the tank bottom and the ice coils.
4. Spreader bars of the full width of the section must be used between the lifting cables to prevent damage to the
section.
5. For extended lifts or where hazards exist, it is recommended to use the lifting devices in conjunction with
safety slings placed under the unit.
Support Requirements
ON A LEVEL CONCRETE PAD
The unit should be continuously supported on a level concrete pad. After the unit is set into final position, the tank
bottom should be sealed airtight all around to prevent condensation formation (see figure). The sealer is shipped
loose with the unit, together with the air pump.

ON 3 I-BEAMS
If continuous support is not possible, an alternative recommended support arrangement consists of 3 parallel I-
beams extending the full length of the unit: 2 supporting beams should be located along the unit length and 1 beam
should be located on the centreline of the unit. (see figure)
Each beam should be sized for 65% of the total operating weight. If a unit is installed on I-beams additional
insulation of the tank bottom is necessary to avoid the formation of condensation.
Installation on 3 I-beams
ON A ROOF
For installation of the unit on a roof, additional field insulation between tank bottom and the roof is required to
prevent condensation formation on the ceiling of the floor below (see figure). Recommended insulation material is a
vapour tight cork layer.

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.
Air Pump Installation
The standard BAC delivery consists of a centrifugal air pump (with an inlet air filter), a threaded adaptor and a
flexible discharge sleeve to be connected to the customer provided air piping. A non-return valve is shipped loose
with the air pump for field installation.
After the unit has been rigged into position, the air pump can be installed. The recommended air piping is shown in
the figure: the air supply is taken from the ambient air. The air pump is to be mounted on a clean, dry and vibration
free surface which is flat and will support the unit. Special pads are not required.
The mounting surface should be levelled and the pumps must be securely bolted in place. It is recommended that,
in case of outdoor installation, the air pump is installed under a shelter. The air pump should be located within 6
meters of the air distribution inlet piping. If a more remote location of the air pump is required, consult your local
BAC representative.
