WARNING: System fluid under pressure and/or at high temperatures can be very hazardous. Before servicing,
reduce system pressure to zero or isolate the vessel from the system. Allow system to cool below 100°F and
above 35°F. Failure to follow this instruction may result in serious personal injury and/or property damage.
B. INSTALLATION
It should be noted that the solubility of air into water decreases as pressure drops and/or as temperature rises. Placing
the Bell & Gossett Series CRS separator before the pump inlet will also help pump performance and increase seal life.
CAUTION: Installation and maintenance must be performed by a qualified professional. Service should not
be performed on any component in an active hydronic loop. Before attempting to make any required adjust-
ments, properly isolate and drain the branch loops that require service and allow the valves to reach a safe
handling temperature and zero pressure condition. Use proper safety equipment including gloves, goggles,
or similar tools to avoid contact with system fluids and common hazards. Failure to follow these instructions
could result in personal injury and property damage.
Figure 2 shows suggested mounting locations for a heating or cooling system.
The separator must be installed vertically.
Do not install on a dead end pipe or in an overhead joist space.
