SAFETY INSTRUCTIONS
Hint!
This manual must be carefully read and understood prior to installingand servicing the compressor (package)
General Safety
All service operations described in this servicemanual are only to be carried outby well-trained/qualified personnel and even then only after this service manualhas been read carefully and is fully understood.
Personal safety
Observe all (inter)national and/or local safety standards, measures and regula-tions during reinstalling, repairing and connecting the compressor (package).
Mechanical safety
If the compressor does not have to be removed from its base, it is advisable toput warning labels on vital parts of the compressor saying that the plant is out-of-operation and must not be started up.If the compressor has to be opened for service,the refrigerant has to be pumpeddown and the electric supply has to be cut off.After having run the initial 100 operating hours,it is essential (in both new andmodified plants) to replace the red running-in discharge oil filter element with thepermanent grey filter element. Also replace the running-in suction gas filter ele-ment.Check the direction of rotation is correct before re-starting the compressor.

PREFACE
General
1. All documentation can be downloaded via our web site.
2. Grasso’s technical manuals includes “generic paragraphs”; this means that itcan occur that not all data as described is relevant for the current compres-sor series as mentioned in this manual. (For instance, not all compressor ser-ies are suitable for all mentioned refrigerants or not all compressor seriesincludes two-stage compressors)
Directives
Equipment is based on Pressure Equipment Directive (PED 97/23/EG) regula-tions and according to Machine Directive (MD 2006/42/EG) regulations.
The applied standards are:NEN-EN-IEC 60204, NEN-EN-ISO 12100, NEN-EN-ISO 13857, NEN-EN 378
pador9130gbr_64 15.03.2017
NEVER CHANGE POSITIONS!
Warning
Never change positions of parts when re-assembling the compressor.E.g. cylinder liners, suction valves, discharge valves and relief valveshave to be replaced always in the origional position.

1 MAINTENANCE
1.1 Replacement piston rings and cylinder liners
Hint!
Recommendation/warning!For major overhauls or every repair where piston rings are beingreplaced it is strongly recommended to replace the cylinder liners aswell. This is very important for the next reasons:
For the best sealing between piston rings and cylinder liners, piston rings have torun in on the cylinder liner’s inner surface. Therefor a new cylinder liner with ahoning profile (crosshatching) in the best condition is absolutely required. Pistonrings cannot run in properly on worn out or partly worn out cylinder liners. Withouta decent honing profile no proper sealing between liners and rings can be ach-ieved which may result in- or contribute to a bad performance of the compressor.Further on, this honing profile with the right crosshatching is demanded for agood lubrication between piston rings and liners and for the right oil distributionon the liner’s inner surface.
Fig.1: New honing profile and crosshatching with the right angle
After being in operation for many running hours cylinder liners and piston ringswill wear out and most cylinder liners will become unworn ridges (bumper rims oredges) due to the displacement of the piston rings inside the liner. The upperunworn ridge occurs at the upper death end and upper side of the upper pistonring and the lower ridge occurs at the death end of the lower side of the lower (oilscraper) ring. In many cases intermediate and oil scraper rings cause their ownbumper ridges. (Bumper steps) Also, both upper and lower edge are set by theworn shape of the piston rings. This clearly explains why new piston rings canbreak when used in old/worn cylinder liners due to hitting the unworn bumperridges at high speed. (See also picture below)Therefor: Never install new pistons with new piston rings in old cylinder liners. Itis strongly recommended to replace the cylinder liners too.

1.2 Running-in oil filter has to be installed after an overhaul or big repair
Hint!
This is why and when the running in oil filters are required:
Warning
A running in oil filter has always to be installed after an overhaul orbig repair for the 1st 100 hours of operation!The oil and oil oil filters have to be replaced by new oil and filters.Due to running-in wear of liners and piston rings, it's normal that theoil becomes grey during the 1st 100 operating hours.After 100 operating hours, the oil could slightly become clear again.
1.3 SMS FACTOR
General
The following maintenance has to be distinguished:
1. Grasso Maintenance Monitor (GMM) is appliedMaintenance A, B and C, service intervals are determined on measured val-ues of GMM
2. GMM is not applied:Service intervals according to Service and Maintenance Schedules (SMS)tables in combination with operating conditions
MAINTENANCERunning-in oil filter has to be installed after an overhaul or big repair
pador9130gbr_610 15.03.2017
Warning
GMM is not used: The running hours mentioned in the SMS tablesshould only be used as a reference for maintenance intervals.The number of running hours mentioned in the SMS tables have to beadjusted accordingly depending on the operating conditions of thecompressor (speed, evaporating temperature, condensing tempera-ture, refrigerant, start frequency, capacity control steps, etc.. Thismeans that the service intervals could be significantly different.The running hours mentioned in the tables are based on a single stagecompressor running at -10oC/+35oC, NH3 at nominal speed. In thiscase the SMS factor = 1, in all other cases the maintenance intervalshave to be adjusted accordingly.
1.4 Legend
Warning
These operations cover routine maintenance and are meant as a guideonly. Lack of maintenance, frequency of stop/starting, extreme operat-ing conditions etc could lead to accelerated wear.

1.5.1 Compressor
General remarks about check list;
1. Check list for compressor only; all other components have to be maintainedaccording to their specific manuals (IMM and SIM).
2. All items of the list below marked “check“, have to be checked visually andchecked for proper working.
3. Some components have to be measured.For measuring details refer to SIM.
4. Measuring means also that visual inspection is required.
5. Visual inspections:The visual inspections during maintenance are of importance; measurementsshould be carried out at the moment that visually abnormalities are detected.The result of the inspection determines whether one or more parts have to bereplaced. For more detailed information refer (SIM) and Installation and Main-tenance Manual (IMM).
MAINTENANCEDescription Maintenance ABC when GMM is applied
pador9130gbr_612 15.03.2017
6. Oil and oil return systems:The quality of the oil effects the oil consumption and the life time of the mov-ing parts. For oil return systems or systems in which soluble oil is being used,we advise to check (or have checked) the quality of the oil every 5000 hoursand - if necessary - to renew the oil and/or filters. If there is no oil analysisavailable, we advise to renew the oil. By regularly carrying out oil analysesand registering them in a log, aberrations will be noticed in an early stage,which may prevent or reduce resultant damage(s).
Note 1:When renewing the oil, in the crankcase the oil in the oil separator and the oilreturn or oil rectifier system (if fitted) has to be renewed.
Note 2:Pre-lubricate the compressor before re-starting. Used or filtered oil shouldNEVER be added to a compressor under any circumstance. Use only new oilas selected from the Grasso oil table. Oil charging via the suction line of thecompressor is not allowed.
