Installing the Ductwork
Use ductwork to connect the unit to the supply and return outlets in the wine cellar. Use only insulated ductwork
to minimize cooling loses, prevent sweating, and to reduce noise.
Use ductwork on the condenser section to redirect or absorb sound, to bring in outside air to the unit inlet,
and/or to exhaust the hot air out of the ambient space
安装管道系统
用通风管道连接酒窖， 应该尽量使用带隔热绝缘的通风管道，以减少冷气流失，防止产生冷
凝水， 也减少噪音。
冷凝部分（段）使用风管可起定向消声作用，也可以把室外空气送到主机进风口，和/或 将
热气排出室内环境空间。
NOTE: Do not exce ed a total of 7.5 metres for each length of ductwork run.
注：
每条管道长度不要超过 7.5 米。
CAUTION
注意
RISK OF DAMAGE TO EQUIPMENT
Avoid crimping the flexible ducts. This chokes down the inside area and reduces the airflow
causing the unit to operate erratically.
Be sure all ducts and surface in contact with the airflow are insulated
and have a vapor barrier on the outside surface.
Uninsulated ducts and surfaces cause bare exposed metal surfaces to sweat,
further degradation of the insulation and a loss of equipment cooling capacity.
