Operation and Periodic Inspection
•
After all piping work has been completed in accordance with the
specific piping system designed when the decision to utilize the
PowerTrap System Package was made, check once again to make sure
that all pipe connections have been tightened, gaskets have been
inserted where needed and all parts are securely installed.
•
During commissioning and test runs, as well as during start-up of normal
operation, take measures to prevent people from coming into direct
contact with vent and overflow outlets. At the start-up of operation, large
quantities of condensate may flow, causing the Power Trap System
Package to momentarily overload. If this occurs, hot Condensate may
spurt from the pipe connections, the vent piping or overflow piping and
could result in burns, other injuries or damage to equipment.
WARNING
When disassembling or removing the product, wait until the internal
pressure equals atmospheric pressure and the surface of the product
has cooled to room temperature. Disassembling or removing the
product when it is hot or under pressure may lead to discharge of fluids,
causing burns, other injuries or damage.
CAUTION
During maintenance/disassembly all connections, piping and bolts should
be removed slowly to prevent fluids from spurting due to the release of
retained internal pressure. Failure to do so may result in burns or other
injury with the discharge of fluids.
CAUTION
Install properly and DO NOT use this product outside the recommended
operating pressure, temperature and other specification ranges.
Improper use may result in such hazards as damage to the product or
malfunctions which may lead to serious accidents. Local regulations
may restrict the use of this product to below the conditions quoted.
CAUTION
Be sure to use only the recommended components when repairing the
product, and NEVER attempt to modify the product in any way. Failure to
observe these precautions may result in damage to the product or burns
or other injury due to malfunction or the discharge of fluids.
CAUTION
Installation, inspection, maintenance, repairs, disassembly, adjustment and valve
opening/closing should be carried out only by trained maintenance personnel.
Operation
(1) Valve Operation
Refer to the drawings in "Installation" on page 8 to become familiar with the
symbols used for the various valves.
If water hammer has occurred, immediately cease operation and close any valves
that are operating.
a) Drain condensate in the condensate receiver by opening the condensate blow
valve [Vt], making sure the condensate blow valve [Vt] is piped to a safe area.
If the condensate receiver is filled up with condensate, condensate may spurt
from the vent pipe [Sv] during
PowerTrap
exhaust.
Make sure to close the condensate blow valve [Vt] after condensate is
drained.
b) Slowly open the exhaust valve [Ve].
c) Slowly open the valve [Vm] on the motive medium supply pipe. Make sure that
there is no sound of flow from the exhaust pipe [Se] or the check valve [Ci] on
the condensate inlet pipe.
d) Slowly open the valve [Vo] on the condensate outlet pipe.
