Electrical Shock Hazard
Capacitor retains charge a

voltage at capacitor has dissipated
(<10V DC) with hand held voltmeter
before servicing. LED2 light
between CN24 and CN26 should be
Riesgo de Descarga Eléctrica
El capacitor re
ene carga una vez
voltaje del capacitor se haya disipado (<10V
DC) apoyando la mano sobre el
vol
metro
antes de realizar el servicio técnico. La luz
LED2 que se encuentra entre CN24 y CN26
deberá estar apagada.
Risque de choc électrique
Le condensateur conserve sa charge après la
coupure de l’alimenta
on électrique. Avant
de procéder à une répara
courant au condensateur s’est dissipé
(<10 VCC) à l’aide d’un voltmètre manuel. Le
voyant LED2 entre CN24 et CN26 doit être
éteint.
Conditions Needed for Basic Operation
3-minutes of time delay from the call for heating or cooling
