Caution
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.
ATTENTION
Au moment de l’entretien des commandes, étiquetez tous les fils avant de les débrancher. Les erreurs de câblage peuvent nuire au bon fonctionnement et être dangereuses. S’assurer que l’apperiel fonctionne adéquatement une fois l’entretien terminé.
