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 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.
•
When beginning operation, make sure that the operator stays well clear
of the release area of the vent line and overflow piping.
At the start-up of operation, large quantities of condensate may flow,
causing the PowerTrap to momentarily overload. If this occurs in open
systems, hot condensate may spurt from the vent piping or overflow
piping and could result in burns, other injuries or damage to equipment.
WARNING
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
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
Be sure to use only the recommended components when repairing the
product, and NEVER attempt to modify the product in any way. Failure to

opening/closing should be carried out only by trained maintenance personnel.
Operation
(1) Valve Operation
Refer to the open-system piping drawing in “Installation” on page 8 to become
familiar with the names and locations of the various valves.
If water hammer occurs, immediately cease operation and close any valves that are
operating.
a) Slowly open the valve on the exhaust pipe.
b) Slowly open the valve on the motive medium supply pipe.
Make sure that there is no sound of flow from the exhaust pipe or the pumped
medium inlet pipe.
c) Slowly open the valve on the pumped medium outlet pipe.
d) Slowly open the valve on the pumped medium inlet pipe.
When using a manual valve for venting air on a closed system, leave the valve
slightly open until the PowerTrap has cycled 2 or 3 times in order to release any
air inside the system, then close the valve.
