Page 8: Operation
The HP45 steam trap operates with no loss of steam and automatically and quickly drains air, non-condensable gases and large quantities of cold water on start-up. -
Page 9: Safety Note
The equipment needed to proceed with any maintenance programme is listed in Table 1. The HP45 trap has an external adjustment screw which permits flushing the trap seat and setting the discharge temperature of the condensate in the inlet line. - Page 10 Replacing the bimetallic element Spares available to repair (See Section 7). 6.3.1 Dismantling the steam trap: Isolate the steam trap. Remove the blind nut (9), the lock-nut (10) on the adjustment screw and the cover nuts (7) on the cover (6). Tighten the adjustment screw on the unit to disengage it from the cover using a screwdriver (maximum blade diameter 7 mm in order to insert it into the thread on the cover).
- Page 11 6.3.3 Adjustment: In a closed return system, close the discharge line and open the test valve. Open the upstream isolation valve slightly. Tighten the adjustment screw a few turns clockwise, and wait a few moments for the steam trap to reach the required temperature and for steam to be present. Move the adjustment screw up (anticlockwise) until the valve comes into contact with the valve seat.

8. Fault finding 1. Make sure upstream and downstream valves are open. 2. Check external strainers for clogging; blowdown or dismantle and clean. 3. Backpressure too high. Downstream system must be corrected. Backpressure will also lower the discharge temperature. Trap fails to pass 4. - Page 14 IM-P623-03 ST Issue 6...
