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.
