(3) Condensate Outlet Piping
a) There is no steam trap installed in
the unit. Make sure to install the
steam trap provided as as a
standard accessory. (When using
another steam trap, contact TLV.)
b) Make sure that the piping installed
between the unit and the steam
trap is as short as possible, with as
few bends as possible so the
condensate will flow naturally down
into the trap.
c) Make sure to pipe the discharged
condensate to a safe area such as
a pit. The temperature of steam
condensate discharged from the
unit exceeds 100
C.
Do not use
PVC or lead piping intended for
water supply.
d) When recovering the condensate,
install a check valve on the
secondary side of the steam trap to
prevent backflow when the unit is
shut down. The back pressure of
the condensate recovery piping
should be lower than the steam
pressure in the unit. (The internal
steam pressure can be confirmed
with the pressure gauge installed
on the left side of the unit.)
e) Make sure to insulate the
condensate outlet piping as it
becomes very hot.
(4) Hot Water Outlet Piping
a) Install a valve at the hot water outlet
for maintenance. (When operating
water with a valve, it is
recommended to install different
valves for operation and
maintenance.)
b) For use in applications where hot
water is in direct contact with skin,
such as handwashing, make sure
to install a safety eqipment such as
a thermostatic faucet on the
secondary side on the unit.
