Maintain clearances as shown on the dimensional drawing for servicing and as referenced in N.E.C. All piping should be designed and installed to avoid any loadings on the feed system connections or piping. Install pump discharge piping so that accessibility and maintenance on the pumps can be done with ease and that pumps can be removed for service if required.

There are two connections supplied for make-up water on the HFS system and one connection on the CFS model. A manual fill connection (top center) is supplied for a by-pass around the standard make-up water connection (HFS only). The standard make up water connection is located on the side of the unit and is tied in directly with a level control to maintain minimum level of water in the vessel.

The condensate return connection is located on top of the tank. All condensate returns should be piped to this connection for entrance into the feed system. Since this vessel is an atmospheric tank the condensate returns coming back should be of low pressure and will be introduced to atmospheric conditions once entering the tank. If high-pressure returns are required to return to this tank, they should be reduced to a low pressure before entrance. A steam pre-heater assembly (optional) may have been supplied with the unit. This connection is for high-pressure steam and is reduced and controlled via a pressure/temperature regulating valve and enters the tank through a sparge tube. This has been sized based on specific conditions given at the time of ordering. For proper operation and maintenance of the valve and proper installation, please reference the valve manufacturer’s instructions supplied with the unit. This connection is used to preheat the water in the tank and is controlled based on a temperature pilot, with the sensor located in the tank.

There are two vent connections supplied on the HFS unit and one on the CFS unit that should not be reduced. One is a 3” vent connection and the other is labeled “blowout opening” on the HFS model only. The tank vent connection must be vented to the atmosphere and piped to a safe discharge location for hot temperatures. The blowout opening is designed as an additional safety condition against having pressure in the tank. The blowout opening has a neoprene rubber stopper installed so if pressure is built up in the tank, the stopper will blow out of the connection relieving the pressure in the tank.

NOTE:

The tank should never, under any circumstances, be installed to become pressurized.
