• Moter
- Motor operating current shall be less than the
rated current labeled on nameplate.
- When checking the motor, pay attention to
its operating condition. Timely clean dust
inside and outside of the motor to prevent
poor ventilation. Carry out regular disassem-
bling and cleaning, and replace bearing in
accordance with the operating condition.
The bearing replacement shall follow the
specified brand and model.
- For belt driven fan, the motor position can be
adjusted by the tightness of the bolts.
• Filter
- Carry out regular inspection on filter in accor-
dance with the operating condition. If the pres-
sure difference exceeds the manufacturer
specified value by the, clean or replace the
filter. After the filter re-installed, check the seal-
ing of the filter positioning frame.
- If the filter is washable, please choose one of
the following when washing:
a. Use vacuum cleaner to collect dust, grease,
etc. from the upper side of the air.
b. When heavily polluted, rinse after soaking
in neutral detergent for a few minutes. No
knead or wring during washing. Put the filter
into the unit after completely dry.
- Do not wash the non-washable filter which
can’ t be cleaned, otherwise it will affect the
filtration efficiency and cause air quality fail to
meet the design requirement.
- The filter is directional. Please pay attention
during installation.
- Stop using the MAHU, when replacing and
cleaning filter. Otherwise, it may cause burn-
ing and other unforeseen accidents to the
motor, and also pollute the air.
• Cooling and heating coil
- Regularly check coil cleanliness, clean if nec-
essary. When using high pressure cleaning,
be careful with aluminum fins to avoid da-
mages.
- The scale in coil will reduce cooling and heat-
ing capacity. Please use chemical agents to
clean the scale after consulting with the pro-
fessionals.
- Hot and cold water quality needs to be man-
aged as the quality of cold and hot water
flowing into the coil will affect the coil service
life. Bad water quality will accelerate the cor-
rosion of copper pipe. In severe cases, leak-
age occurs due to cavitation.
