AJUSTE DE LA VÁLVULA DE EXPANSIÓN
Las válvulas de expansión de los gabinetes Freedom
vienen previamente ajustadas de fábrica, pero
puede ser necesario hacer algunos ajustes para las
condiciones específicas de la tienda. Antes de intentar
ajustar las válvulas, verifique que el evaporador esté
despejado o solo cubierto ligeramente con escarcha, y
que el exhibidor esté en un rango de 10 °F (6.5 °C) de
su temperatura de operación esperada.
Después de arrancar el sistema y luego de 24horas
de operación, verifique que el nivel de aceite en el
compresor se encuentre a la mitad de la mirilla en el
compresor. Añada el tipo de aceite recomendado por
el fabricante del compresor según sea necesario para
mantener el nivel correcto.
Si requiere operar el sistema de refrigeración
para verificar su funcionamiento, siga estas
recomendaciones:
» Instale los estantes del gabinete de exhibición
antes de la operación.
» Evite las corrientes de aire causadas por puertas
abiertas, ventiladores u otras fuentes.
» Los conductos de descarga y retorno de
aire deben permanecer abiertos y libres de
obstrucciones en todo momento.
» Mueva provisoriamente la perilla de control
de refrigeración a la posición de operación
más cálida durante condiciones ambientales
no controladas, a fin de reducir al mínimo la
acumulación de agua de descongelamiento.
» Si se han desenergizado las charolas
del calentador luego de un ciclo de
descongelamiento, aún puede haber agua
estancada en las charolas. Vuelva a aplicar
electricidad a las charolas por el tiempo
suficiente para eliminar el agua restante antes de
reiniciar la refrigeración durante las condiciones
ambientales no controladas.
»No camine sobre la parte superior del gabinete.
No almacene artículos o materiales inamables en
la parte superior del gabinete.
