Introduction
The Heatsavr HS140 Automated Kit is designed to significantly reduce heat and water loss from your swimming pool. This innovative system utilizes a transparent liquid pool cover that forms a barrier on the water's surface, effectively minimizing evaporation. It is a safe, biodegradable, and environmentally friendly solution for maintaining pool temperature and conserving water.
Key benefits of using the HS140 Automated Kit include:
- Cuts overnight heat loss by up to 50%, helping your pool stay warmer for longer.
- Conserves water lost to evaporation by up to 50%, reducing the need for frequent refilling.
- Offers an easier alternative to traditional plastic pool blankets, eliminating the need for manual covers and rollers.
- Does not break apart or clog filters, ensuring hassle-free operation.
- Effective on uniquely shaped pools and those with water features like spillovers or waterfalls.

Setup and Installation
The HS140 Automated Kit includes the HS115 Automatic Metering System, which automates the daily application of Heatsavr liquid. Proper installation ensures optimal performance and longevity of the system.
Unpacking and Inspection
- Carefully unpack all components from the packaging.
- Verify that all parts are present and undamaged. Refer to the packing list for a complete inventory.
- If any parts are missing or damaged, contact Heatsavr customer support immediately.
Mounting the Dosing Unit
- Choose a suitable location near your pool equipment pad, ensuring it is protected from direct sunlight and extreme weather conditions.
- The unit should be mounted securely to a vertical surface using appropriate fasteners (not included). Ensure it is level.
- Allow sufficient space around the unit for easy access to controls and for refilling the Heatsavr liquid bottles.
Connecting to the Pool System
- Connect the intake tubing from the dosing unit to the Heatsavr liquid bottle. Ensure the tubing reaches the bottom of the bottle for complete liquid extraction.
- Connect the output tubing from the dosing unit to a suitable return line or skimmer in your pool system. Ensure the liquid is dispensed into an area with good water circulation.
- Secure all tubing connections to prevent leaks.
Power Connection
- Plug the power adapter into a grounded electrical outlet. Ensure the outlet is protected by a Ground Fault Circuit Interrupter (GFCI) for safety.
- Verify that the unit powers on and the display is active.
Operating Instructions
The HS140 Automated Kit is designed for daily, automated dosing of Heatsavr liquid. Follow these steps to program and operate your unit.
Calculating Dosage
- The standard dosage rate for Heatsavr is 1 ounce per 400 square feet of pool surface area, applied daily.
- Since the HS140 system applies the dosage over 7 days, you will program the unit to dispense the total weekly dosage divided by 7 as a daily application.
- Example: For a 400 sq ft pool, the daily manual dose is 1 oz. For the automated system, you would program 1/7th of an ounce to be dispensed daily. For a 2800 sq ft pool (7 x 400 sq ft), the daily manual dose would be 7 oz. For the automated system, you would program 1 oz to be dispensed daily (7 oz / 7 days).
Programming the Dosing Unit
The HS115 unit features buttons for PROGRAM, EVENT/PRIME, HOURS, MINUTES, and SECONDS/DAY. Consult the unit's display for current settings.
- Press the PROGRAM button to enter programming mode.
- Use the HOURS, MINUTES, and SECONDS/DAY buttons to set the desired daily dosage volume. Refer to the unit's specific programming guide for precise volume-to-time conversion.
- Press PROGRAM again to save the settings and exit programming mode.
- Use the EVENT/PRIME button to manually prime the pump if needed, ensuring liquid flows through the tubing.
The unit will now automatically dispense the programmed amount of Heatsavr liquid daily.
Maintenance
Regular maintenance ensures the efficient and continuous operation of your HS140 Automated Kit.
Liquid Refill
- Monitor the Heatsavr liquid level in the bottles regularly.
- Replace empty bottles promptly to ensure uninterrupted dosing. Simply unscrew the cap, insert the intake tubing into a new bottle, and secure the cap.
Tubing and Connections
- Periodically inspect all tubing for kinks, cracks, or blockages.
- Check all connections for tightness to prevent leaks.
- Clean any residue that may accumulate around the pump head or tubing connections.
Pump Head Inspection
- Inspect the peristaltic pump head for wear. Over time, the tubing within the pump head may require replacement.
- Refer to the HS115 specific manual for instructions on replacing the pump head tubing if necessary.
Troubleshooting
This section provides solutions to common issues you might encounter with your HS140 Automated Kit.
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not powering on. | No power to outlet; faulty power adapter; internal unit issue. | Check power outlet and GFCI. Test power adapter. If issues persist, contact support. |
| No liquid dispensing. | Empty Heatsavr bottle; kinked or blocked tubing; pump head wear; incorrect programming. | Replace bottle. Inspect and clear tubing. Check pump head tubing. Verify programming settings. Prime pump. |
| Inconsistent dosing. | Air in tubing; pump head wear; fluctuating power. | Prime pump to remove air. Inspect and replace pump head tubing if worn. Ensure stable power supply. |
| Pool not retaining heat/water as expected. | Incorrect dosage; insufficient circulation; extreme weather conditions. | Recalculate and adjust dosage. Ensure proper pool circulation. Note that extreme conditions may reduce effectiveness. |
