Checking the Piping
Use only under conditions in which no water hammer will occur. The
impact of water hammer may damage the product, leading to fluid
discharge, which may cause burns or other injury.
CAUTION
Check to make sure that the pipes to be connected to the product have been
installed properly.
1. Is the pipe diameter suitable?
2. Is the piping where the product is to be installed horizontal?
3. Has sufficient space been secured for maintenance?
4. Have maintenance valves been installed at the inlet and outlet? If the outlet is
subject to back pressure, has a check valve (TLV-CK) been installed?
5. Is the inlet pipe as short as possible, with as few bends as possible, and installed
so the liquid will flow naturally down into the trap?
6. Has the piping work been done correctly, as shown in the figures below?
Requirement
Correct
Incorrect
Install catchpot with the
proper diameter.
Diameter is too small.
Make sure the flow of
condensate is not
obstructed.
Diameter is too small and inlet
protrudes into pipe interior.
To prevent rust and
scale from flowing into
the trap, the inlet pipe
should be connected
25 to 50 mm (1 to 2 in)
above the base of the
T-pipe.
Rust and scale flow into the
trap with the condensate.
When installing on the
blind end, make sure the
flow of condensate is not
obstructed.
Condensate collects in the pipe.
