3. PRE-OPERATION PROCEDURES
Installation Procedure
11. After installation
Unit may tip over or fall, causing injury or death during an earthquake or other unforeseen
incident. Be sure to stabilize unit properly to assure safe operation and a safe work area
(earthquake-resistant fitting is available for WG1001 as an option).
12. Check drainage temperature of cooling water.
●
When draining boiler, drainage temperature may exceed 60 °C. Drain water to a location
distant from the work environment in order to avoid a direct contact with hot water. Failure
to do so may result in burn injury.
●
High temperature cooling water may flow out. Discharge the water at a place away from the
drainage facility if PVC pipes are used for the piping of drainage. Hot cooling water may
cause damage or degradation to the piping. VP pipe (JIS K 6741) is used for the PVC pipe,
and DV-RR joint and plug-in socket (JIS K 6739) are used for the fitting. Use optional drain
trap (WG251: OWI11, WG1001: OWI21) if the drainage temperature does not fall below
60 °C. Likewise, use drain trap if not using the above mentioned piping and joints, even if
drainage temperature is 60 °C or less.
13. When drainage temperature of the sink does not fall below 60
°
C
●
Use optional drain trap (WG251: OWI11, WG1001: OWI21).
●
Drain trap reduces temperature by temporarily storing the drainage water. And then adds
tap water to cool it furthermore. The drainage water will be discharged after adequately
cooled.
