2.5.3 Pipe Anti-freezing

Condensate drainpipes of air conditioners and water refill pipes of humidifiers may freeze and
thereby be blocked or crack in low-temperature areas. Anti-freezing measures must be taken
for the pipes.
Wrap the pipes with an electric heating belt, starting from the water refill and drainage ports
on a pre-fab. module to the frozen soil layer. Bury the remaining pipes underground (the
temperature at a specific depth underground is always above 0° C).

The pre-fab. module must be located in an area with proper drainage. To prevent ponding
which may affect equipment operation, deploy drainage channels before constructing a
concrete foundation.
Dispose of drainage water in accordance with local laws and regulations.
Anti-freezing measures must be applied for pipes in low-temperature areas.
