Chapter 5 Maintenance and Inspection
Ammonia Semi-hermetic Motor with K-series Compressor 5.1 Precautions for Maintenance
5-2
 In the disassembly/inspection workplace, secure a sufficient space for temporary
storage of the removed parts and tools, replacement parts, and for the disassembling
work as well as safety passages, and then put up necessary off-limit signs.
 In the workplace, secure a sufficient space and refrain from putting tools directly on
the floor or from haphazardly laying wires.
 Keep the floor clean all the time. Leaving the floor smeared with oil and the like
causes it to be slippery and may result in the fall and injury of personnel. Thus, do not
leave it but wipe it off right away.
 Make sure that the temperature of the high temperature sections such as head covers
and discharge lines has been cooled down to normal ambient temperature, before
working on them.
 When disassembling and reassembling the compressor, use the specified tools
properly. Before starting to use those tools, gain the full understanding of their
characteristics and the method for use.
 During the maintenance service, keep the tools clean all the time. Using those tools
smeared with oil increases the risk of slip and fall, leading to an injury. Also during
the service, there is a risk of foreign matters intruding inside the compressor to cause
its damage.
 Parts are slippery with oil. Fully watch out for the risk of any object falling down. Pay
attention to any parts falling down, which could lead to personal injury.
 Before disassembly, inspections, and handling of the compressor and the
semi-hermetic motor, sufficiently understand the disassembly and assembly
procedures.
 When removing a part, be careful not to damage it.
 Place the removed parts on a clean workbench in an orderly manner.
 For cleaning parts, use kerosene and machine parts cleaning sprays available on the
market.
 Washed parts shall be dried by compressed air or wiped up using clean cloth. Do not
use synthetic textiles or woolen textiles to prevent fibers from attaching the parts.
 Removed bolts from each part should be classified into each used section to prevent
confusion.
 For details of overhauling the compressor, refer to the "Reciprocating Compressor K-series
instruction manual" Chapter 5. Note that although this manual describes the disassembling and
reassembling practice of the semi-hermetic motor, it does not define the maintenance procedure to
the minute details, but only covers its key points only.
 If complete disassembly and reassembly of this product are required, please contact your nearest
sales office or service center of MAYEKAWA.
 The figures marked with brackets [ ] immediately following each part name in this manual indicate
the part numbers given in the Sectional View of the Motor shown in Section 2.4 of this manual and
parts configuration table.
