6. Drainage work
Drainage work is needed to drain water from the humidifying tray and condensation
formed in the test area out of the chamber.
Gravitational drainage is employed for the drainage system.
Keep the drain hose sloped downward to prevent the water from getting stagnant
inside and run the water into a pit.
Location of drain hose: rear underneath.
Drain tube: length about1m from the chamber, O.D.

Notice
・
If collecting drainage in a container, regularly check water level to make sure it
does not overflow. If using the continuous water supply or additional water
tank (option), do not drain water into a container.
・
To prevent backflow into the chamber, do not share the drainage line with
other equipment. Also, leave the water tank drain hose and drain pipe ends
open to the atmosphere.
・
Raising the drain pipe about 5 cm or more off the floor or the chamber’s
supporting surface will form a pocket in the line, whereby preventing proper
drainage and possibly causing water to backflow into the dew tray or the
mechanical parts compartment. Also, if any part of the drain pipe is higher
than the drain outlet, water will not drain smoothly, possibly flooding the test
area floor.
< Procedure >
1) Connect the drain pipe from the chamber rear panel to a drainage system or run it
into container or pit. * Drain pipe ID: Ø12 mm
Whenever needed to check, maintain or run the chamber, connect the drain hose
to the nipple and drain water from the chamber. Fit the hose over the nipple and
press inward until hearing the connection catch.
