(4) Exhaust Piping:
!" The exhaust pipe diameter should be at least 15 mm (½”).
!" The exhaust pipe should be connected to the top of the condensate receiver/
reservoir.
!"
For Open Systems
: If the GP exhaust line has to discharge to atmosphere, a
sound level of approximately 90 dB may be emitted from the exhaust pipe
discharge outlet for intervals of two or three seconds. If soundproofing measures
are necessary, install a silencer. (If the exhaust line is connected to the
condensate receiver, the sound level will be below 60dB.)
!" Make sure that the distance from the ground to the highest point on the exhaust
pipe (where it enters the receiver/reservoir pipe) does not exceed 3 m (10 ft).
If it exceeds 3 m (10 ft), condensate must be drained from the exhaust pipe in
order not to obstruct the exhaust. Implement one of the following
countermeasures: (See the figures below.)
(a)
For Open Systems only:
Add a float-type steam trap to the exhaust pipe at
a point just above where the exhaust pipe exits the unit body. (Figure 1)
(b)
For Open and Closed Systems
: Add piping connecting the exhaust pipe to
the condensate inlet pipe between the reservoir pipe and the strainer, being
sure to install a check valve on the piping to prevent backflow of condensate
from the condensate inlet pipe to the exhaust pipe. (Figure 2)
(5) Inlet and Outlet Piping
!" Install a 60-mesh strainer on the PowerTrap condensate inlet pipe.
The installation should be in a location that allows sufficient space for
maintenance of the strainer.
!" Ensure the inlet and outlet check valves are installed in the correct direction. The
check valve on the inlet pipe in particular should be installed right next to the
PowerTrap .
!" The check valves should be ones provided by TLV, as other check valves may
not give the proper discharge capacity.
