Spencer Hermetic Gas Boosters General Instructions ® Caution: Do not operate machine in "Surge" or in unstable ow range for extended periods. Spencer Service Spencer service begins upon receipt of your request for equipment purchase. Our engineers welcome the opportunity to discuss your installation problems and will assist in determining specication requirements if so desired. To serve you promptly, we maintain an inventory of electric motors and machine parts for the various types of equipment. Also, by combining under one roof, the constantly supervised manufacturing, assembly, and test procedures, Spencer can assure you of a unit capable of optimum performance under the most severe service conditions. All Spencer gas boosters are factory tested for load capacities and noise and vibrational characteristics. This guarantees long, trouble-free operation.

No equipment shall be furnished for acceptance based on results of eld testing. The Spencer Turbine Company will not assume any responsibility under the terms of this limited warranty on equipment which has not been paid for in full. This warranty does not apply to any equipment that has been disassembled, repaired, or otherwise altered by any person without the written authorization of Spencer’s service department, nor does it apply to any product that has been subject to failure due to corrosive or abrasive attack, misused, damaged, or improperly installed, nor does it apply to motors, controls, and components not manufactured by Spencer.

This warranty is in lieu of and excludes all other warranties, including without limitation, any warranty of merchantability, tness for a particular purpose, or conformance to purchaser’s specications. Handling This machine has been carefully balanced and tested at our factory. It is essential, therefore, that it be handled with care during installation in order that you may be assured satisfactory performance. If the machine is to be stored for some time before being permanently installed, it must be carefully protected from dampness and dirt. Location Install the machine in a cool, dry place free from dirt and dust. After placing the machine in its operating position, be sure that the blower and motor are readily accessible for servicing by allowing several feet of clear space around the machine. Inaccessibility can prove costly in both time and labor. Caution: Do not locate unit in excessively hot area (above 100°F). Foundation No special foundation is necessary for the equipment. A level concrete oor or block is recommended, although any other substantial oor will prove satisfactory. The machine and its base should be placed on the insulation pads normally furnished with it. Caution: Gas Boosters should not be bolted down or anchored in any way. Piping All piping should be of ample size to minimize frictional loss. It is absolutely essential that all joints be gastight and that there be no leaks in the system. Leaky gas pipes consume a surprising amount of power and impair the operating efciency of the machine. Piping should be properly supported without producing any stress and strain on the machine casing. It is further recommended that a suitable exible connection be used to connect it to the piping. Caution: If the piping system is to be leak-tested using high pressure air, be sure to either bypass or disconnect the gas booster. High pressure air will seriously damage the gas booster. Electrical Be sure that the motor furnished with this machine is wound for the same type of current available at the installation. Follow the wiring instructions furnished. Wire and fuses should comply with NEC and/or local codes. It is important that proper equipment be used. All A.C. machines should be equipped with a magnetic contactor or a manual or automatic compensator depending on the machine size and the installation regulations of the local power company. The starters should have thermal overload protection as well as true lowvoltage protection. Ball Bearings The motor ball bearings in this machine have been designed specically for the function they must perform. Impeller loads, both radial and thrust, are carried by one of the bearings. Again, it is essential that replacement bearing be of the same type as the original bearings In many machines, the front (opposite shaft extension) motor bearing normally has been designed to take thrust.
