• Model: GP10L-1AJ
Unlike other models, the GP10L-1AJ has an outlet port for the dual installation of
the overflow pipe and vent pipe. When installing the piping, connect the piping to
the flange on the top of the condensate receiver, and then install the overflow
pipe and vent pipe by separating each pipe as shown below.
Observe the same precautions as for other models for installation.

(8) Check Valve to Prevent Return Water Hammer
①
:
If length "A" in the following figure (from the
PowerTrap
to a rise in the piping) is
longer than 30 m (100 ft), return water hammer may occur in the piping after a
discharge cycle finishes. To prevent this, installation of a spring-return type check
valve just above the rise is recommended.
(9) Check Valve to Prevent Backflow Water Hammer
②
:
If length "B" in the following figure is longer than 500 mm (19
11
/
16
in) and steam
(including flash steam) enters the condensate recovery line, backflow water
hammer may occur in the piping. To prevent this, installation of a spring-return
type check valve close to the condensate recovery line is recommended.
