What to do if my TTI FABRICATION CPST-80 Heat Pump is not starting?
If your TTI FABRICATION Heat Pump isn't starting, check if the main power is off. If it is, wait for the power to be reinstated. Also, ensure the switch is on. Replace any burnt-out fuses and switch the circuit breaker back on if it drops out.
Why is the TTI FABRICATION CPST-80 blowing air but not heating properly?
If your TTI FABRICATION Heat Pump is blowing air, but the heating isn't good enough, a few things could be happening. First, the air inlet or outlet might be blocked; clean them out. Second, there could be a 3-minute time lag protection activated, so just wait. Finally, the temperature might be set too low; increase it as needed.

The TTI FAB Stratos Swimming Pool Heat Pump is designed to efficiently and economically heat swimming pool water, providing comfort and pleasure to users.
The Stratos series offers various models (Stratos 40, 50, 65, 80, 100, 120) with heating capacities ranging from 40,000 BTU to 120,000 BTU. All models operate on 230V, 60Hz/1Ph power. Breaker requirements vary from 20A to 50A depending on the model. Current consumption ranges from 6.2A to 24A (Current*) and 6.9A to 26A (Current**), with heating power from 1.5 kW to 5.7 kW (Heating power*) and 1.7 kW to 5.9 kW (Heating power**). Compressor RLA/LRA values range from 7.8A/43.5A to 37.5A/168A, and fan motor ratings are 0.43A to 1.8A.
The design pressure for high-side operation is ≥500 PSIG, and for low-side operation, it is <250 PSIG. Noise levels are between 50 dB and 55 dB. All models use R410A refrigerant, with charges ranging from 40 oz (1.13 kg) to 92 oz (2.6 kg). Net weights vary from 45 KG to 95 KG. The recommended water circulation flow for all models is 15-45 GPM (57-170 l/m).
The product is designed to work effectively in ambient temperatures between 7°C to 35°C (45°F-95°F), though efficiency is not guaranteed outside this range. The machine provides heat function only and must be properly grounded.
The heat pump incorporates a high-efficiency titanium heat exchanger, ensuring sensitive and accurate temperature control with a clear water temperature display. It includes a comprehensive protection system against high pressure, low pressure, and low water flow. An auto-stop protection feature is activated when outdoor temperatures fall below a certain threshold. The unit also features temperature-controlled compulsory defrosting and uses an international brand compressor for reliable performance. Installation and operation are designed to be easy.
The control panel includes indicators for "Settings," "Required temperature," "Clock," "TIME ON," and "TIME OFF." Users can switch between "Hot" and "Cold" modes (though the machine only provides heat). The display shows the current time when off and the swimming pool water temperature when on.
Water Temperature Setting: To set the water temperature, users press the "Δ" or "▽" key. The controller display will flash, allowing adjustment with the "Δ" or "▽" keys. After 5 seconds, the display reverts to normal mode. Users can switch between Fahrenheit and Celsius by holding the "MODE" key for 10 seconds.
Time Setting: The time can be set whether the machine is on or off. Press the "CLOCK" key; when the clock flashes, press the "CLOCK" key again to set the hour using "Δ" or "▽". Before the flashing stops, press the "CLOCK" key to set the minute using "Δ" or "▽". After adjustment, press "CLOCK" again, and the water temperature will be displayed. The display returns to normal mode after 30 seconds.
Timer On/Off: To set the timer on, press the "TIMER ON" key. When the indicator light is on and the time flashes, press "TIMER ON" again to set the hour using "Δ" or "▽". Before flashing stops, press "TIMER ON" to set the minute using "Δ" or "▽". After adjustment, press "TIMER ON" again, and the water temperature will be displayed. The display returns to normal mode after 30 seconds. The process for setting the "Timer Off" is similar, using the "TIMER OFF" key.
Cancel Timer On/Off: To cancel the timer, press either "TIMER ON" or "TIMER OFF". When the number flashes, press the respective timer key again. When the timer indicator light is off and the LED shows water temperature, the timer is canceled. The display returns to normal mode after 30 seconds.
Proper positioning is crucial for optimal performance. The heat pump relies on surrounding air for operation and should not be installed in enclosed spaces like garden sheds or basements. Sufficient free space is required around the unit: 60 cm (2 feet) in front of the evaporation coil, and 120 cm (4 feet) in front of all other surfaces, the fan, and the service panel. Objects should be placed as far away as possible from the air evacuation area.
The device should not be installed under a roof that could cause it to be buried under snow or receive excessive water without gutters. Avoid direct sunlight on the regulator to prevent display readability issues. Automatic sprinklers should not be near the pool heat pump. The unit must be installed on a flat, firm, and level surface, preferably a concrete slab. Users should be aware that the device will produce condensation. Using a solar blanket to cover the pool is highly recommended to reduce heat loss, especially during colder nights.
All STRATOS models have 1 ½-inch diameter connections. For maximum efficiency, water flow must be between 57 l/m (15 U.S. GPM) and 170 l/m (45 U.S. GPM). Flows outside this range will cause damage and void the warranty. A set of valves, including an adjustable automatic bypass valve, should be installed to isolate the heat pump and adjust water flow, especially with water pumps of 2 HP or more. The maximum operating water pressure is 2.0 bars (30 PSI); exceeding this will void the warranty.
Any automatic chemical distribution system (chlorinators, brominators, etc.) must be installed so that its water output is located after the pool's heat pump. Failure to comply with this rule will void the heat pump's warranty. Salt chlorinators are considered inline chlorinators and must follow this rule. Pressurized chlorinators or brominators, which use a small quantity of water from the filter to create a concentrated solution, require check valves highly resistant to corrosion. Only manufacturer-supplied or recommended valves should be used.
Electrical connections must be performed by a qualified electrician in accordance with national, provincial, and local regulations to ensure safety and proper functioning. A circuit breaker must be installed close to the heat pump in an accessible location. The electrical box should never be opened without shutting off power to all sources. If the heat pump has a pool pump control option, the circuit breaker for this pump must also be closed. The heat pump's spec sheet provides voltage and amperage requirements. A damaged power cord must be replaced by a qualified electrician.
Before any examination or repair, the power supply to the heater must be cut off. The machine should be cleaned with household detergents or clean water; gasoline, thinners, or similar fuels should never be used.
During winter or prolonged periods of inactivity, the power supply should be cut off, the inlet pipe tap opened, and water drained from the machine by disconnecting the water pipes.
General Precautions:
The device provides failure codes to assist in troubleshooting:
Not starting:
There is air outlet but the heating is not satisfactory:
Users are advised not to disassemble or repair the swimming pool heater themselves and to contact professionals for assistance.
