A servicing and installation handbook


To be able to install, commission and carry out maintenance or repairs to
even the most basic Refrigeration system, it is essential that the engineer has a
sound k**wledge of the system operation, the functions of the various valves,
the controls employed in the system, and the specialist tools or equipment
necessary to carry out those tasks.
Generally, larger Refrigeration companies employ engineers who specialize
in servicing and others involved only with the installation of equipment.
Smaller companies require engineers to be proficient in both service and
installation practice.
This manual deals with the fundamental principles of service, installation
and commissioning, but **t necessarily to any specific manufacturer’s
*recommendation or equipment

The service engineer


Obviously the need for service and maintenance on existing plant exceeds
the demand for new installations and for this reason it is essential that all
engineers are conversant with the various service operations and diag**stic
procedures; they are dealt with in Part One.
The engineer must be conversant with the type and location of system
service valves, with the gauge manifold and all types of gauges used with
refrigeration equipment.
The ability to diag**se why a system is **t operating correctly, or merely to
establish that it is providing optimum service, starts with the fitting of gauges
to record either the operating or static pressure of the plant, depending upon
the circumstances.
A high percentage of service calls are due to refrigerant leakage either
from fractured pipework joints or from defective components which have


been
subjected to internal or external corrosion to cause a leak.
Often a service call can result in the replacement or relocation of a component,
necessitating a change in the pipework design or route so the two
aspects, servicing and installation, can**t be completely divorced from each
other.
The response to a service call is a venture into the unk**wn and the engineer
must be prepared for every eventuality
