19.1.5. PROTECTION DEVICES
1. Clean or replace the filters.
For the installation to operate correctly, it is imperative that the air filter, located on the air intake of the treated air
coil, is cleaned regularly.
Cleaning intervals vary depending on the amount of impurities in the air to be conditioned. It is recommended that
the filter is replaced at regular intervals.
A dirty filter creates a decrease in air flow across the heat exchanger, which decreases the installation's output and
hinders fan motor cooling.
19.1.6. HYDRAULIC CIRCUIT
1. Check that the hydraulic circuit is filled correctly and that the fluid circulates freely without any sign
of leaks or air bubbles.
2. Inspect filter cleanliness.
BEFORE CARRYING OUT ANY OPERATION ON THE EQUIPMENT,
CHECK THAT THE ELECTRICAL POWER SUPPLY IS SWITCHED
OFF AND THAT IT CANNOT BE SWITCHED ON INADVERTENTLY.
