ASSEMBLY: B-51. 5.0 ASSEMBLY AND PREPARATION FOR STARTING • Before locating the unit or blower, the surface must be completely clean and dry, and free of any oil. • The surface of the base must be scrubbed and clean, as well as the holes for the anchor bolts. Blow them with clean air if possible.

Page 8: Storage
• The motor is installed on a tilting base (PG-30/PG-35/PG38 units). Do not forget to leave enough cable to be able to change the belts and tighten them more easily. • NOW FILL WITH OIL TO THE CORRECT LEVEL. 5.1 STARTING •... - Page 9 6.2 INSTALLATION OF MOTOR WITH REVERSIBLE POLES. • Follow the instruction manual. • Every time the speed is reversed, the motor must be at zero revs. 7.0 ALIGNMENT OF PULLEYS The alignment of the pulleys can be carried out with the help of a thread or steel rule.

VERY IMPORTANT AFTER TWO HOURS OF * AFTER ADJUSTING THE SUPPORT PLATE TO SERVICE, RE-TIGHTEN THE SET THE CORRECT BELT TENSION BELTS LOCK THE HINGE NUTS 8.0 OIL. Oli splash provides lubrication to both gears and bearings. Correct oil level is indicated in the drawing. IMPORTANT Excess filling will provoke an increase in the oil temperature, and therefore incorrect mechanical operation of the blower. -
Page 11: Oil Table
290 and 400 cSt (ISO VG-320) should be used. N.B. As regards brands of libricating oil, C.M. Pedro Gil recommends using quality names, with no specific preferences. These are 5 litres cans available for customers whose needs do not justify the purchase of 50 litre or 200 litre barrels. -
Page 12: Maintenance (Main Points)
9.0 MAIN POINTS FOR MAINTENANCE 1- Check the oil level of the sumps with the machine stopped. 2- Regularly clean the filter cartridge. (depending on the environment in which the machine is operating). 3- Change the oil in the sumps every 4000 hrs. (first change at 500 hrs). -
Page 13: Maintenance Plan
9.1 MAINTENANCE PLAN • After a few hours of service, it is important to re-tighten the belts, as it is during the first few hours when adjustments between the pulleys and belts are required WEEKLY TASKS • Check the suction filter, clean it if the pressure loss exceeds 50 mbar. •... -
Page 14: Cleaning Filters
To check the blower, the suction and thrust pipes must be disconnected. The oil level gauges must always be clean. Check them and clean them when visibility is reduced. After cleaning, the grease must be changed. In very difficult cases our technical service should be consulted and an occasional visit from one of technical specialists should be requested. -

The PG unloading valve removes the air produced when the blower is started up. This eliminates the When the blower is started up, the air escapes Whwn the blower is started up, the air escapes through the when the blower is started up.

Page 22: Rng-Type Blowers For Gas
17.0 RNG-TYPE BLOWERS FOR GASES The instructions for service and maintenance are the normal ones as provided in this book In contrast to air blowers, the RNGs, for gases, keep the shaft sealed through the incorporation of a grease chamber, located between the two retainers, through which the shaft passes. It is essential to maintain this chamber to preserve this seal. -
Page 23: Rs-Type Blowers With Gaskets
18.0 RS-TYPE BLOWERS WITH GASKETS The instructions for service and maintenance are the normal ones as provided in this book The only difference is that the RS-type model has a separate compression chamber with oil-filled sumps, and to seal the shaft it has a gasket. As the blower is installed in a pressurised pipeline, the gaskets must be adjusted gradually at the points indicated in the diagram. -
Page 24: Possible Faults And How To Detect Them
19.0 POSSIBLE FAULTS AND HOW TO DETECT THEM. IF UNUSUAL NOISES OR HIGHER THAN NORMAL TEMPERATURES ARE OBSERVED, THE MACHINE MUST BE STOPPED IMMEDIATELY, AND THE CAUSE MUST BE IDENTIFIED AND REPAIRED. DO NOT START UNTIL THE BLOWER HAS BEEN REPAIRED. THE BLOWER MAKES PECULIAR NOISES - Base bolts loose. - Page 25 OIL IN COMPRESSION CHAMBER, OIL LOSS - Casing with excess oil, level too high. Reduce oil level. - When the machine is stopped, the correct oil level should be according the manual point 9.0. - Clean the compression chamber with a degreaser. DRIPPING OR CONDENSATION THROUGH THE DRILLED EXIT HOLES FOR CONDENSED VAPOUR - If the blower works with air, the drilled exit holes for condensation must be open.
