Use the external controller to select either the "Pool" or "Spa" to heat. Deactivating Chiller Set the external controller to "OFF".
2 - Maintenance 2.1 Water Chemistry Check water chemistry regularly and maintain within recommended levels. Standards vary in different residential and commercial applications. Follow all local applicable codes. Failure to heed the following may result in damage to equipment. NOTICE Do not allow water to flow through chiller when refinishing or acid washing a pool.
2.2 Cleaning Equipment Cleaning and polishing your chiller regularly can protect its appearance and longevity. More frequent servicing may be required for chillers located in sandy or coastal areas where sand and salt spray can damage equipment. Failure to heed the following may result in injury or death. WARNING Possible electric shock hazard - Deactivate power to all electrical devices on the pad when washing chiller.
Table 3 - Polishing Agents • The trademarks used in approved cleaning and polishing agents are property of their owners and are not related to AquaCal ® 2.3 Clearances Proper air circulation is required for the chiller to operate efficiently. The following diagrams show the minimum clearances required for the proper operation of the chiller.
2.5 Water Flow Rates Maintain water flow rates as indicated. Please note, these specifications relate to the chiller only. Code- specified whole system turnover rates must be satisfied. Failure to heed the following may result in damage to equipment. NOTICE Water flow exceeding maximum flow rates will negatively affect the total pool filtration performance and may damage the chiller.
Table 4 - Temperature Chart PLEASE NOTE - Temperature differences are based on pool water temperatures of 69° to 75° F. ® For water temperatures outside this range, contact AquaCal . See "Contacting AquaCal AutoPilot, Inc." on page 1. 2.7 Planned Maintenance An annual inspection and maintenance program is strongly recommended starting no later than one year after installation of the chiller.
Light Freeze Conditions A light freeze is when the ambient air temperature falls below 32 degrees Fahrenheit for less than 8 hours. Typically during light freeze conditions circulating (or moving) water will not freeze. Temporarily activate the filter pump for continuous operation during light freeze conditions. Hard Freeze Conditions A hard freeze is when the ambient air temperature falls below 32 degrees Fahrenheit for more than 8 hours.
3 - Appendix 3.1 Identifying Model Specifications 1. Find Data Plate - The data plate is usually posted on the side of the equipment or the inside of the chiller's access Data Plate Example plate. 2. Find the model number on the data plate. The first letters and numbers indicate the model type.
Site voltage drop is minimized and utilities are not subjected to large in-rush demands of electrical current. ® Part number is based on number of chillers to be controlled. Call AquaCal for assistance with correct configuration. See "Contacting AquaCal AutoPilot, Inc." on page 1.
Temperature Port Kit This kit is used to install a temperature port. This port can be used to adjust water flow using Delta-T. The kit comes with port, installation components, and a temperature probe. PART NUMBER Kit # (STK0096) Page - 19...
A fault code indicates a specific issue or condition that will require action before the equipment can resume operating. Please perform the following troubleshooting. If the issue reoccurs, please see "Contacting AquaCal AutoPilot, Inc." on page 1. Failure to heed the following may result in injury or death. WARNING Repairs must not be attempted by untrained or unqualified individuals.

Chiller Not Running 1. Confirm equipment is receiving power. Is the chiller display illuminated? If not, confirm the main breaker (located at the power supply panel) and the disconnect switch (located near the chiller) are both turned on. If the display still does not illuminate, it is recommended that the chiller installer or electrician confirms chiller is receiving power.
Water Coming From Chiller The water may be normal condensation produced as a by-product of the chiller's refrigeration process. The chiller can produce 8 to 10 gallons of condensation per day depending on the humidity of the ambient air. Determine if the water is condensation or a possible leak. 1.
