Electrical Shock Hazard
Capacitor retains charge a er
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 capacitorre enecargaunavez
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
