AVERTISSEMENT
Pressions dangereuses!
Tout manquement aux consignes de sécurité
préconisées ci-dessous risquerait d'entraîner un
éclatement du serpentin susceptible de provoquer des
blessures graves voire mortelles. Les serpentins
contiennent du fluide frigorigène sous pression. Lors
du nettoyage des serpentins, maintenez la température
de l'agent de nettoyage pour serpentin à moins de 65,5
°C (150 °F) pour éviter toute pression excessive dans le
serpentin.

manufacturer's instructions. If desired, heat the
solution BUT DO NOT EXCEED 150ºF maximum to

pressure sprayer is used:
a. do not allow sprayer pressure to exceed 600 psi.
b. the minimum nozzle spray angle is 15°.
c. maintain a minimum clearance of 6 in. between the
sprayer nozzle and the coil.
d. spray the solution perpendicular (at 90°) to the coil
face.

spray the opposite side of the coil. Allow the cleaning
solution to stand on the coil for five minutes.
