SAFETY INFORMATION

Used and maintained properly, your heat pump will provide year-upon-year of safe and economical service. However, as with any mechanical or electrical device, to get the most from your heat pump–while insuring personal safety for you and others–certain operational and maintenance factors must be observed.

Likewise, excepting a few minor owner-capable maintenance items (explained later in this manual), repair and service of your heat pump must be performed only by experi- enced service personnel. Should you, the owner, suspect your heat pump is not per- forming properly, by referring to the section in this manual entitled: "Troubleshooting," you will be able to determine if a call for service is required. Your installer can be one source of service, or AquaCal Customer Support personnel stand ready to assist you at: (800) 786-7751.
