TROUBLE OF CONTENTS 2 installation , Operation AND Maintenance MANUALFOR LIQUID RING AIR compressor INTRODUCTIONThis manual contains Instructions for the installation , Operation and maintenanceof your Travaini liquid ring compressor system. It has been designed to providesafe and reliable ser vice. However, since the compressor is a piece of rotatingequipment, the operator must exercise good judgment and proper safety practicesto avoid damage to the equipment or personal injur y.

4 The Instructions in thismanual are intended for personnel with a general training in Operation andmaintenance of rotating Travaini compressor system is a factor y assembled system including allcomponents required for Operation . We have taken great care to use high qualitycomponents for long trouble-free Operation . SAFETYIt is assumed that your safety department has established a program based upona thorough analysis of industrial hazards. It is important that due consideration be given to these hazards which arise fromthe presence of electrical power and rotating parts. Proper installation and care ofprotective devices is essential. In the following safety procedures you will encounter the words WARNING,CAUTION AND NOTE.

5 They are intended to emphasize certain areas in the interestof personal safety and satisfactor y compressor Operation and Maintenance . Thedefinitions of these words are as follows: WARNING:An operating procedure, practice, etc. which, if not correctly followed, could result in personal injur y or loss of life. CAUTION:An operating procedure, practice, etc., which, if not strictly obser ved, could result in damage to or destruction of equipment. NOTE:An operating procedure, condition, etc., which is essential to safety procedures are to be used in conjunction with the Installation, Operation and Maintenance Instructions contained in the compressor INSTALLATIONThe design of plant piping systems, foundations, and other areas of systemdesign is the responsibility of others, not Travaini Pumps, USA or itsrepresentatives.

6 Data and comments are offered as an aid, but Travaini Pumps,USA cannot assume responsibility for the design and Operation . We recommendthat the customer consult a specialist skilled in the design of foundation, piping,and equipment location so as to supplement and interpret this information toensure a successful installation . WARNING:Install, ground and maintain equipment in accordancewith local and national electrical codes. CHECK UPON ARRIVALS hipment of systems ordered with control panels suitable for wall mounting willconsist of two packages, one containing the control panel and one the compressorsystem. Remove each component from the respective crate and check thoroughlyfor possible shipping damage. If systems are ordered with control panels pre-wired, follow the above procedure.

7 LIFTING:Lift the unit to the required location by supporting from at least four points on the saddle or by slings under each end of the LIFT OR MOVE THE UNIT BY DECK MOUNTED STORAGE(STORE UNIT IN ACCORDANCE WITH THIS AND compressor O & M manual PROVIDED.)a)In instances where the unit is to be stored for a lengthy period prior to installation and Operation , it should be located in a clean, cool, dr y areaprotected from the elements. Special care should be taken with the controlpanel to ensure it is protected from dust and ) When shipped from the factor y, the pump unit is filled with a water soluble rust preventative solution. Should the unit be installed and tested on site, itshould be placed in ser vice immediately, since the rust preventative solutionwill be removed on running.

8 When this is not possible, the pump and watertrap must be filled with a similar solution to ensure that they :When putting the unit into ser vice, do not connect thebuilding air distribution system to the package until the unit hasbeen tested for air quality. PREPARATIONRead this manual and other literature provided. If questions arise, consult thedistributor or the factor y. Verify that the proper utility ser vices required to operate the equipment areavailable. Among these are the electrical supply, voltage, current, number ofphases, the water supply temperature, pressure, flow capability and quality, drainsize and capacity. 3 a)LOCATIONI nstall the compressor in an accessible place, as close as possible to thecompressed air use area.

9 Allow adequate space for Operation as well as forscheduled Maintenance operations involving dismantling and inspection ofparts. Consideration must be given to the environment. Proper ventilation isnecessar y and extremes of dampness or temperature should be ) SEALING LIQUID SUPPLY Proper Operation of the liquid ring compressor is dependent upon acontinuous supply of cool, clean sealing liquid, normally water, which entersthe pump through the sealing liquid inlet connection on the suction side of thepump and is discharged together with the compressed gas. The sealing liquidentering and leaving the pump also ser ves to carr y away the heat ofcompression imparted to the liquid ring during the working cycle. Ser vice liquid supply to each compressor is fixed and set at the factor y forthe correct amount by a flexible flow orifice.

10 compressor per formance data as published is based on the use of 60 Fahrenheit (15 C) water as the sealing liquid. When operating with water ofhigher temperature, a drop in capacity may be adequate supply of good quality water must be available to meet the systemrequirement. The following data ser ves as a guideline for the water supply:Water Hardness maximum 200 ppm Dissolved Solids maximum 200 ppm Chlorides maximum 10 ppm pH minimum 7 NOTE: Mineral deposits on pump internals can cause operatingproblems and are not covered under warrantee. Mount and bolt the unit onto a concrete pad adequate to support the weight asshown on the attached drawing.
