Be careful of frost and dew
As shown in the right figure, it’s supposed that a high temperature absorbing air
condition A and a low temperature absorbing air condition B are plotted on the line
figure, then a high temperature air A is heat-exchange by the unit and Point C
represent the trend of saturation curve. In this case, it will cause the dew or
frost inside the unit. To avoid this, you are required to heat a low temperature
air B up to B’ so as to get C’ below the saturation curve before using the unit.
Avoiding the coming of insects
Energy Recovery Ventilator is intended to exchange outdoor air and indoor air. When the outdoor air comes in,
maybe bring the insects from outdoor pipe hood to internal unit.
As inset occurrence is affected by natural environment, it’s recommended to use the pipe hood with fly net
when using the unit under the environment of many insects such as near the street light.
It must operate with filter.
Turn on /off the switch correctly.
It’s forbidden to use the
「
normal
ventilation
」
for the dew will be produced
in and indoor air inlet if operating the
mode
「
normal ventilation
」
when the
room is heated in winter.
If not using the filter, heat exchange
core is clogged with dirt and dust,
performance will be lowered and
even the unit doesn’t work.
If repeatedly turning on or off the
switch not only cause the wrong
operation but affects the relay
inside and damage it.

安装要求：与室内环境相同。
使用注意事项
必须使用过滤网。
运转开关的转换动作必须准确。
如果不使用过滤网，热交换芯上会积满
脏物和灰尘，性能因此而降低，甚至不
能使用。
如果急速重复转换开关的话，不仅易
造成误操作，而且会给开关及内部的
继电器带来不良影响，从而引发故障
冬季室内供暖时如果设置
「
普通换气
」
会
引起主机或室内送风口处结露，所以冬
季禁止使用
「
普通换气
」。
防止昆虫侵入
全热交换器是将室外的新鲜空气吸入到室内的一种机器。所以室外环境存在昆虫时，可能会将昆虫等从室外防雨罩吸到机器内部。
由于昆虫问题的产生是受自然环境左右的，所以请在昆虫较多环境或给排气口周围有路灯的、易招昆虫的环境下使用时，推荐与
带防护网的防雨罩等并用。
小心结露和结霜
