Bell & Gossett V1000266 Series CRS Coalescing Removal Separator - Manual (Page 4)

WARNING: RUPTURE OR EXPLOSION HAZARD - Like most pressurized tanks, this tank can over time corrode,
weaken, and burst or explode. Failure to follow this instruction may result in serious personal injury or death
and property damage.
WARNING: CHLORINE & AGGRESSIVE WATER HAZARD - The water quality can significantly influence the life of
your product. You should test for corrosive elements, acidity, total solids, and other relevant contaminants, in-
cluding chlorine and treat your water appropriately to insure satisfactory performance and prevent premature
failure. Failure to follow this instruction may result in serious personal injury or death and property damage.
Before filling and starting the operation of a HVAC system, a properly applied and sized pressure relief valve must be
installed and in good operating order.
During filling and start-up after servicing, the system pressure should be closely monitored to ensure the pressure does
not exceed the pressure relief valve rating.
Consult the applicable pressure relief valve manufacturer’s instructions as necessary.
System Venting and Purging
After initial venting and purging of air from the system, more air will be released from the water as it is heated. An
optional Bell & Gossett No. 98 Air Vent may be assembled at the top of the Series CRS separator.
If the system has multiple loops or zones, the supply water for all loops and zones must pass through the Series CRS
separator for complete and continuous air removal. In case the piping arrangement does not permit the installation of
a single separator on the main, additional separators should be installed on each loop or zone. In this event, only one
expansion tank is required for the system.
Even with a No. 98 air vent installed on the separator, it is recommended that additional Bell & Gossett air vents be
installed on high points in the system.
CAUTION: Uncontrolled venting of water can occur with automatic air vents if foreign material prevents vent
from closing. Unwanted flow should be directed to a drain. Failure to follow these instructions could result in
property damage and/or moderate personal injury.
NOTICE: Never use the separator itself as a form of piping support. Please support separator and piping ac-
cording to the local building code. Failure to follow these instructions may result in property damage.
A manual blow down valve can be added to the blow down connection at the bottom of the separator. The function of
the blow down valve is to facilitate the purging of sediment from the vessel.
CAUTION: Use unit lifting lugs only to lift unit as shipped from factory. Unit must be empty and disconnected
from pipe, and other restraints. Use proper rigging procedures. Failure to follow these instructions could result
in injury or property damage.
Be aware of water weight in the separator and connected piping when installing your system. The wet filled weight of
the Series CRS separators can exceed the strength of the supports used. Make sure that provisions are made to properly
support the wet filled separator.
Welding to the pressure vessel boundary will void the ASME stamp.
