Surface Cooler Precautions

(1) When the air conditioner is not in use in winter, the remaining water in the pipe should be drained to prevent the water from freezing due to the low temperature in winter and cracking the steel pipe;
(2) The water in the surface cooler should not contain impurities such as sand;
(3) Insulation should be done well in winter to reduce heat loss or avoid frost on the pipe.
