Page 6 2.2 Heating Water 1) Heat pump’s mode is set to “HEA”. 2) Thermostat is set to desired water temperature. 3) Water pump’s time clock is overridden to 24-hour operation. This is only necessary for an initial startup. After the water reaches the desired temperature, the time clock can be reset to a normal time frame operation.
Page 7 2.4 Heat Pump’s Defrost Operation WARNING - Failure to heed the following may result in injury or death. ROTATING FAN PROP HAZARD: fan may start during defrost cycle. Keep hands clear of fan blade at all times. Frost can form on the heat pump evaporator coil under certain weather conditions. When enough frost has formed to inhibit heat pump operation, the heat pump starts a defrost cycle.
Page 9 SECTION 3 - MAINTENANCE WARNING - Failure to heed the following may result in injury or death. Possible electric shock hazard - Disconnect power to all electrical devices on pad when washing heat pump. Do not restore electrical power until equipment is completely dry.
Page 10 3.2 Monitoring Conditions 3.2.a Pool Chemistry CAUTION - Failure to heed the following may result in equipment damage. Stop water flow when refinishing or acid washing pool. Failure to follow these instructions may damage equipment and voids heat pump warranty. CAUTION - Failure to heed the following may result in equipment damage.
An annual inspection and maintenance program is strongly recommended starting one (1) year after installation of heat pump. See Figure 4 for recommended inspection checklist. AquaCal AutoPilot can perform this service in limited areas. Contact Customer Support for more information.
Page 13 SECTION 4 - INSTALLATION WARNING - Failure to heed the following may result in injury or death. Installation of this equipment by anyone other than a qualified installer can result in a safety hazard. The information contained throughout the “Installation” section is intended for use by qualified heat pump installation technicians, familiar with the swimming pool/spa service industry safety standards and methods.
4.2.a Indoor versus Outdoor Installation Outdoor heat pump installations are recommended. Indoor installations require specialized airflow controls and can be problematic. If no viable alternative exists, contact the AquaCal AutoPilot Engineering department for assistance prior to proceeding with an indoor installation.
Follow all relevant local, state, or national requirements regarding wind load anchoring. When anchoring is required, use AquaCal AutoPilot optional Hurricane Anchoring Kits. AquaCal AutoPilot anchoring kits satisfy the very stringent Florida Building Code Section 301.13: Wind Anchoring Requirements. Contact AquaCal AutoPilot to obtain the correct anchoring kit for the heat pump being installed.
