It is recommended that water quality be tested by local professionals.
Anti-freezing measures must be applied for pipes in low-temperature areas.
2.5.2 Drainage Requirements
Condensate drain outlets and humidifier drain outlets are available at the ends of pre-fab.

Drainpipes must be able to withstand a temperature above 105°C; otherwise, pipe
deformation may occur .
Drainpipes near the pre-fab. module drainage port must be able to withstand a
temperature above 200°C; otherwise, pipe deformation may occur.
