This document is an instruction handbook for a Tebas Inverter swimming pool heat pump. The heat pump is designed and built solely for private swimming pool use. Tebas dissociates its responsibility if the device is used in any other application. The handbook emphasizes the importance of reading and adhering to all instructions before installation and use. It also states that the handbook can be modified without notice.
Function Description:
The Tebas Inverter swimming pool heat pump is designed to heat swimming pool water. It operates by extracting heat from the ambient air and transferring it to the pool water, allowing for temperature regulation. The device is equipped with a digital controller for setting and monitoring various parameters, including desired water temperature and operating modes. A key feature is its "Inverter" technology, which allows the machine to manage its power for optimal efficiency, low noise, or high power, depending on the selected mode. The heat pump includes a water flow switch to ensure it only operates when water is circulating, preventing damage. It also features heating priority, allowing the heat pump to start the filtration pump if the water is not at the desired temperature.
Important Technical Specifications:
- Operating Temperature Range: "Inverter" range heat pump models are designed to operate from -15°C to +35°C (5°F to 95°F) air temperature, assuming the use of a pool cover. For operation below 0°C, especially with high water temperatures, an electrical heater is advised.
- Water Pressure: Maximum water pressure is 2 bars (29 PSI).
- Water Flow: For correct operation and maximum heat transfer, a water flow of 5 to 7 m³/h (100 l/min) should be maintained.
- Hydraulic Connections: Designed for connection to rigid pressure PVC tubes (for swimming pools) Ø50 mm, directly glued to provided half union connectors. The heat pump should be connected to a filtration circuit through a by-pass system consisting of three valves, placed after the pump and filter.
- Electrical Connections:
- Power Supply: The device requires a 3G 230 V power supply.
- Head of Line Protection:
- TEBAS INVERTER S: 16 A
- TEBAS INVERTER M: 20 A
- Maximum Cable Length (between heat pump and head of line protection, C curve current protection):
- For TEBAS INVERTER S: 25m (2.5 mm²), 35m (4 mm²), 45m (6 mm²), 80m (10 mm²)
- For TEBAS INVERTER M: 30m (4 mm²), 40m (6 mm²), 70m (10 mm²)
- Safety: Power supply must be equipped with grounding and 30 mA differential protection.
- Refrigerant: Contains fluorinated greenhouse gases (R32: 100% CH2F2) in a hermetically sealed circuit.
- CE Standard Conformity: Meets standards for Electromagnetic compatibility (2004/108/EC), Safety requirements for low voltage equipment (2006/95/EC), Pressure Equipment (97/23/CE), Noise production (200/14/CE), and Harmonized standards (NF EN 60335.1,2.40). French standard installation reference: NF C 15 100.
- Pressure Controller: Equipped with an HP pressure controller set at 38 Bar.
- Water Quality Limits: Chlorine concentration less than 2.5 ppm, pH level from 6.9 to 8.
Usage Features:
- Installation Location: Must be installed outdoors, at a distance greater than 2m from the pool, on a flat, horizontal, and stable surface (concrete base ideal). Maintain at least 1m (40") / minimum 30cm (12") of space on the rear (evaporator air inlet) and minimum 3m (120") on the outlet side of the fan for free air circulation. Avoid directing ventilated air towards noise-sensitive areas or places where people gather. Avoid placing the appliance under trees or in areas exposed to water/mud. Insulate water pipes for best performance, especially if the heat pump is far from the pool.
- Start-up Procedure:
- Open the three by-pass valves and then half close the settings valve.
- Start the pool pump.
- Turn on the pool heat pump with the on/off switch.
- Verify the "flow" LED lights up, indicating the filtration pump is working.
- The heat pump will start after a few minutes delay.
- Set regulation and heating parameters using the digital controller.
- Regulate water flow after a few minutes.
- Cover the pool and let the heat pump work for several days to reach the desired temperature.
- Digital Controller (Regulation):
- ON/OFF: Use the dedicated button to start/stop the heat pump.
- Working Modes:
- "Smart" Heating/Cooling: Machine manages power for best efficiency, heating/cooling to desired value (+/- 1°C).
- "Eco" Heating/Cooling: Machine manages power for low noise/low speed, heating/cooling to desired value (+/- 1°C).
- "Boost" Heating/Cooling: Machine manages power for high power, heating/cooling to desired value (+/- 1°C).
- Time Setting: Press the SET key for 3 seconds to set hours and minutes.
- Water Temperature Setting: Press the temperature setting button, adjust with up/down arrows, and wait for automatic storage.
- Working Information Display: Symbols indicate water flow, fan operation, compressor status (blinking during start-time delay), defrosting, and keyboard lock.
- Keyboard Lock: Press up and down arrows simultaneously for several seconds to lock/unlock.
- Water Flow Setting: Adjust water flow through the by-pass setting valve to optimize heating performance. To increase pressure (decrease flow), open the setting valve. To decrease pressure (increase flow), close the setting valve. Ideal by-pass setting is achieved when the manometer indicates a temperature 10-15°C higher than the pool water temperature during "heating boost Hi" mode.
- Heating Priority: Can be connected to the water filtration pump to automatically start it when the pool water temperature is below the desired level. Requires a normally open relay (contactor) with 230V AC coil.
- Winter Setting:
- Turn off the heat pump.
- Close downstream and upstream valves of the by-pass system.
- Drain the exchanger to prevent freezing.
- Open downstream and upstream valves completely to empty the heat exchanger tank before closing them.
- Cover the heat pump with a waterproof cover (special covers available as an option).
Maintenance Features:
- Monthly Checks (User/Qualified Technician):
- Check and clean the evaporator with a soft brush or water jet (do not use high-pressure cleaner).
- Check all electrical and ground connections.
- Check that all electrical connections and terminals are securely connected.
- Check gas pressure (when heat pump is stopped, manometer must indicate a pressure higher than 0.5).
- Yearly Checks (Qualified Technician):
- Check settings.
- Check securities.
- Check all electrical connections and ground.
- Check condenser cleanliness.
- Clean the heat pump casing with soft soap and water (do not use solvents).
- Before Maintenance: The heat pump must be completely stopped for a few minutes before connecting pressure controllers, as high pressure and temperature inside could be harmful.
- End of Product Lifetime: Must be entrusted to a qualified professional (refrigeration technician) for dismantling in accordance with laws (recovery of cooling gas, metallic materials recycling).
- Warranty: Will be invalidated if chemical concentration levels in the pool water are not maintained within specified limits (Chlorine < 2.5 ppm, pH 6.9-8). Never inject chemicals directly into the filtration pump strainer. Warranty will also be cancelled if recommended solutions for technical problems are not followed.
- After Sales Technical Service: In case of technical problems, provide the serial number, manometer values (stopped and working), ON/OFF button status, digital controller display values, programmed settings, fan status, by-pass valve positions, pool dimensions, personal details, and a description of the failure to the dealer.
