5.1
After ensuring the inlet and outlet pipe connections and motive/exhaust connections
are coupled in accordance with Figures 15 and 16, slowly open the motive steam inlet
line to supply pressure to the APT14, APT14HC or APT14SHC. Ensure the exhaust/
balance line is open and not restricted in any way.
5.2
Slowly open the isolation valves in the condensate inlet and discharge lines, allowing
condensate to fill the body of the APT14, APT14HC or APT14SHC.
5.3
The APT14, APT14HC or APT14SHC is now ready to operate.
5.4
When the process plant is operational, the APT14, APT14HC or APT14SHC will
discharge condensate under all pressure conditions into the return line.
5.5
If any irregularities are observed, recheck the installation according to the
recommendations in Section 4. If the unit fails to operate, then consult the fault finding
guide Section 9.
