12.9 - Condenser coil

We recommend, that finned coils are inspected regularly to
check the degree of fouling. This depends on the environment
where the unit is installed, and will be worse in urban and
industrial installations and near trees that shed their leaves.
For coil cleaning proceed as follows:
• Remove fibres and dust collected on the condenser face
with a soft brush (or vacuum cleaner).
• Clean the coil with the appropriate cleaning agents.
We recommend TOTALINE products for coil cleaning:
Part No. P902 DT 05EE: traditional cleaning method
Part No. P902 CL 05EE: cleaning and degreasing.
These products have a neutral pH value, do not contain phos-
phates, 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 surface
2
of 2 m . This process can either be carried out witha TOTALINE
applicator gun (part No. TE01 WA 4000EE) or using a high-
pressure spray gun in the low-pressure position. With pressur-
ised cleaning methods care should be taken not to damage the
coil fins. The spraying of the coil must be done:
- in the direction of the fins
- in the opposite direction of the air flow direction
- with a large diffuser (25-30°)
- at a distance of 300 mm.

The two cleaning products can be used for any of the following
coil finishes: Cu/Cu, Cu/Al, Cu/Al with Polual, Blygold and/or
Heresite protection.
It is not necessary to rinse the coil, as the products used are pH
neutral. To ensure that the coil is perfectly clean, we recommend
rinsing with a low water flow rate. The pH value of the water
used should be between 7 and 8.
WARNING: Never use pressurized water without a large
diffusor. Concentrated and/or rotating water jets are strictly
forbidden.
Correct and frequent cleaning (approximately every three
months) will prevent 2/3 of the corrosion problems.
Never use a fluid with a temperature above 45°C to clean the
air heat exchangers.
