where the unit is installed, and will be worse in urban and
industrial installations and near trees that shed their leaves.

Clean coils guarantee optimal operation of your HVAC
unit. This cleaning is necessary when the coils begin to
become fouled. The frequency of cleaning depends on
the season and location of the HVAC unit (ventilated,
wooded, dusty area, etc.).
Level 2
Clean the coil, using appropriate products.
We recommend TOTALINE products for coil cleaning:
Part No. P902 DT 05EE: traditional cleaning method
Part No. P902 CL 05EE: cleaning and degreasing.
The two cleaning products can be used for any of the

These products have a neutral pH value, do not contain
phosphates, are not harmful to the human body, and can be
disposed of through the public drainage system.
Depending on the degree of fouling both products can be
used diluted or undiluted.
For normal maintenance routines we recommend using 1 kg
of the concentrated product, diluted to 10%, to treat a coil

using a high-pressure spray gun in the low-pressure position.
