Pipe Anti-freezing
Condensate drainpipes and water refill pipes 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 trace heater, starting from the water refill and
drain ports to the frozen soil layer. Bury the remaining pipes underground (the
temperature at a specific depth underground is always above 0°C).
