Sterlco® Condensate Pumps Operation and Installation Instructions Operation & Installation Tel (262) 641-3808 • Fax (262) 641-8625 • www.steamcontrolproducts.com • Bulletin: SCP1-600.3 • Effective: July 1, 2008 • Supersedes: August 23, 2005 Selection of Discharge Piping In selecting condensate pumps and making proper piping connections, the friction in the discharge line from the pump to the boiler is very important. The pressure drop due to friction is sometimes much greater than the boiler pressure.

9037-891 9037-891 SERVICE BULLETIN SERVICE BULLETIN Class 9037 Type HG Series A FLOAT SWITCH CAUTION: Switches are shipped with a bracket attached to the mounting plate. This bracket prevents the float and rod from moving in the tank during shipment. When installing the system, this clearly marked shipping bracket must be removed and discarded. APPLICATIONS: For automatically controlling the liquid level in a closed tank by float movement.
9037-891 9037-891 SERVICE BULLETIN SERVICE BULLETIN FLOAT & LINK POSITIONS PRESSURE: In the use of any of these Float Switches, the pressure limit within the closed tank must not exceed 100 lbs. MOTOR PROTECTION: A float switch of this type does not afford motor protection, however it is quite frequently used as a pilot to operate a starter providing these desirable features. The Square D Co. manufactures a complete line of motor protective switches, information on which will be sent upon request.
038-893 9038-893 SERVICE BULLETIN SERVICE BULLETIN Class 9038 Type CG Series A MECHANICAL ALTERNATOR CAUTION: Switches are shipped with a bracket attached to the mounting plate. This bracket prevents the float and rod from moving in the tank during shipment. When installing the system, this clearly marked shipping bracket must be removed and discarded. APPLICATIONS: The Class 9038 Type C Mechanical Alternators serve to open and close an electric circuit by an upward and downward float movement.
