TRANSPORTATION AND STORAGE
All valves should be inspected at the time of delivery for shipping
damage, missing parts, and conformance with the specifications
The valves should be stored in a sheltered area, or covered to
prevent contamination by the weather or dirt. The valves should be
stored evenly supported on a flat surface. End cap protectors
should be in place when the valves are in storage.
HANDLING
If handled incorrectly the autofrost plug can be dislodged.
Therefore they should be lifted and handled by placing a hand
under the outlet flange rather than the bend/boss.
Hydrants are heavy so always use appropriate lifting devices to
avoid injuries. It is essential that staff undertaking these operations
are adequately trained to avoid accidents.
MAINTENANCE
To prevent injury to the operator or damage to the hydrant
and/or property the hydrant must be isolated and line pressure
removed.
Frequency of maintenance inspections should be based
upon the operational characteristics of the system. As a minimum
an annual inspection is recommended.
During the inspection the following should be checked.
1. All end joints, cover joints and packing for leaks.
2. Tightness of the bolts.
INSTALLATION AND USE
Before use, the hydrant needs to be cleaned so as to remove dirt.
The closing mechanism should be checked to ensure freedom of
movement and proper operation. Prepare the pipe ends as per the
manufacturer's instructions and install the hydrant as per
appropriate instructions for the specified joint.
All pipework should be properly supported to the hydrant. Do not
use the hydrant to force the pipework into position. Standard
wrenches and/or sockets are to be used to tighten all nuts and
bolts. All bolts are to be tightened in a star pattern.
