RIGGING
7
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.

Whenever TSC coils are to be installed in a concrete tank the
following components are provided together with the coils:
- The Ice Logic ice thickness controller: sensors are installed on
the coil, control box is shipped loose, wiring to be done on site.
- The air pump: shipped loose
- Air piping: mounted underneath the coils
- Coil supports: with sufficient height to elevate the coils above
the tank bottom in order to provide space underneath for
water distribution piping supplied by other
- Hold down channels and covers are required to prevent the
coils from floating when completely loaded with ice. These
channels and covers on top of a concrete tank are not part of
BAC’s standard supply.
Contact your BAC representative if assistance is required for the
design of these components.
