Page 3: Heat Pump Options
HEAT PUMP OPTIONS The heart of your heat pump is the patented titanium heat exchanger. One of the primary causes of premature heat pump demise is the failure of the heat exchanger. Ordinary heat exchangers are made from a cupronickel alloy. This cupronickel material is susceptible to attack from the sanitizers used in pools and spas and from other related water chemistry conditions. -
Page 4: Heating Quick Start & Stop
HEATING QUICK START AND STOP 1. Verify Electrical Power is Present at Heater: A. Ensure that the unit has electrical power connected; the heater controller display should be illuminated. B. If the display is blank, be certain the electrical breaker, and heater disconnect, are switched to “ON.”... - Page 5 temperature and maintained per the setting determined previously in: “Set the Heater Controls.” D. In operation, whenever the actual (displayed) water temperature falls below the desired set point, after an initial time delay of 4-minutes, the unit will begin heating. THE HEATER CONTROLLER HAS AN ANTI-SHORT CYCLE TIME DELAY.

Page 7: Operational & Programming Codes
Heat pumps contain no owner-serviceable components. Owner-initiated adjustments, must not be attempted.

Page 8: User Lock Codes
USER LOCK CODE OPTION [ULC]: Heat pumps are shipped from the factory with the [ULC] option disabled. En- abling the [ULC] function permits the heat pump owner to restrict access to the unit’s controls. With the [ULC] function enabled, unless the correct ULC code number is entered, changes to Level-1 programming are not possible. - Page 9 2) When reset to the factory default settings the user lock code [ULC] is deacti- vated and the user lock code number [ELC] is reset to “0.” 3) In addition, all other settings are returned to the factory defaults. If an external controller is in use, contact Aquatherm at 888-297-3826. Ask for assistance with re-configuring the controller for use with an external controller.

Page 14: Seasonal Use & Shut Down
AT START UP: CONTINUOUS CIRCULATION PUMP OPERATION REQUIRED When starting a heat pump for the first time, it must be permitted to operate, contin- uously, until the desired water temperature is attained. This may take several hours, to several days, depending upon the size of the pool or spa and weather conditions. If a time clock or similar device controls the operating times of the water circula- tion pump, temporarily override the water pump controller, allowing for 24-hour, continuous water pump operation. -

“HP5”) shut the heater off. • Before calling for service, always check the filter, the pump basket, and water valve positions and turn the breaker off and back on to clear the error. If the problem persists, please call Aquatherm at: 239-482-0606 MAINTAIN PROPER WATER CHEMISTRY • IMPORTANT! Your heat pump is engineered for exceptional durability and reliability. -
Page 16: Proper Clearances
CAUTION- POOL/SPA REFINISHING OPERATIONS During pool refinishing or acid cleaning, the water flow through the heater must be shut off. Water flow to the heater must remain off until water chemistry is once again in balance and the water is clear in appearance. Failure to follow these in- structions may void heater warranty. CONTROL IRRIGATION AND STORM RUN OFF • Control Irrigation: Irrigation water spray can damage heater components. Regardless of water quality, it is important that irrigation be directed away from the heat pump. -
Page 17: Heating Tips
HEATING TIPS Heating in Cooler Weather... Late night and early morning, generally being the coolest times of the day, are least efficient for heating. For most efficient heating operation, heat pumps should be timed to operate during the warmest, daylight portions of the day. Please set water pump and heat pump controls accordingly. Pool/Spa Blankets A “solar” blanket will significantly reduce your heating bills. Check with the in- stalling dealer to see if your heat pump was sized to be used in conjunction with... -

Is the air blowing out of the top of the unit noticeably cooler than the surrounding air? (With heating indicator light illuminated, a 9°F to 12°F difference is typical.) If not, contact Aquatherm for service at: 239-482-0606. But first, be sure all air coil surfaces are free from obstructions– low roof overhangs, landscaping, walls, fences, etc., can restrict air flow. The heat pump needs good airflow to operate at peak efficiency. -
Page 20: Safety Information
Using a water test kit, or a test strip, check a sample of the water for chlorine or bromine. If the sample tests positive for sanitizer, call Aquatherm for service at: 239-482-0606. If the test is negative, the water is probably harmless condensation. -
