14.6 - Evaporator coil
We recommend, that nned 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, two maintenance levels are used, based on
the AFNOR X60-010 standard:
Level 1
- If the evaporator coils are fouled, clean them gently in a vertical
direction, using a brush.
- Only work on air evaporators with the fans switched off.
- For this type of operation switch off the heat pump if service
considerations allow this.
- Clean evaporators guarantee optimal operation of your unit.
Cleaning is necessary when the evaporators begin to become
fouled. The frequency of cleaning depends on the season and
location of the unit (venti-lated, wooded, dusty area, etc.).
Level 2
The two cleaning products can be used for any Cu/Al coil with
protection.
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.
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 surface
of 2 m2. This process can either be carried out using a high-
pressure spray gun in the low-pressure position.
With pressurised cleaning methods care should be taken not to
damage the coil ns. The spraying of the coil must be done:
- in the direction of the ns
- in the opposite direction of the air ow direction
- with a large diffuser (25-30°)
- at a minimum distance of 300 mm from the coil.
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 ow rate. The pH value of the water used
should be between 7 and 8.
Never use pressurised water without a large
diffuser. Do not use high-pressure cleaners for Cu/
Al coils.
Concentrated and/or rotating water jets are strictly
forbidden. Never use a uid with a temperature
above 45°C to clean the air heat exchangers.
Correct and frequent cleaning (approximately every
three months) will prevent 2/3 of the corrosion
problems.
Protect the control box during cleaning operations.
14.7 - Condenser maintenance
Check that:
- the insulating foam is intact and securely in place.
- the cooler heaters are operating, secure and correctly
positioned.
- the water-side connections are clean and show no sign of
leakage.
