6. Proper Installation
CAUTION
• Take measures to prevent people from coming into direct contact with product outlets.
• Do not use excessive force when connecting threaded pipes.
• Install for use under conditions in which no freeze-up will occur.
• Install for use under conditions in which no water hammer will occur.
1. Before installation, be sure to remove all protective seals.
2. Before installing the trap, blow out the inlet piping to remove all dirt and oil.
3. When hoisting the product, hang the rope around the inlet/outlet as close to the body as
possible.
4. Install the steam trap within the allowable inclination, as shown below. Also make sure that
the arrow mark on the body corresponds with the direction of flow.
5. Install the trap in the lowest part of the pipeline or equipment so the condensate flows naturally
into the trap by gravity. The inlet pipe should be as short and have as few bends as possible.
6. Support the pipes properly within 800 mm (2.5 ft) on either side of the trap.
7. Install a bypass valve to discharge condensate, and inlet and outlet valves to isolate the trap in
the event of trap failure or when performing maintenance.
8. Install a check valve at the trap outlet whenever more than one trap is connected to the
condensate collection pipeline.
9. The use of unions is recommended to facilitate connection and disconnection of screwed
models.

7. Piping Arrangement
Requirement
Install a catchpot with the
proper diameter.
Make sure the flow of
condensate is not
obstructed.
To prevent rust and scale
from flowing into the trap,
connect the inlet pipe 25-
50 mm (1-2 in.) above
the base of the T - pipe.
When installing on the
blind end, make sure
nothing obstructs the flow
of condensate.
• Installation, inspection, maintenance, repairs, disassembly, adjustment
and valve opening/closing should be carried out only by trained
maintenance personnel.
