FAQs
Frequently Asked Questions
1. What temperatures can my SeaAir system safely operate in?
Cooling works best with incoming water temperatures between 60°F and 105°F. Heating operates optimally between 40°F and 80°F.
2. Can I install the HVAC unit in an engine room or bilge?
No. The system does not have ignition protection and must never be installed in any space containing gasoline fumes, LPG/CNG, or fuel-related equipment.
3. What happens if my touchscreen display battery dies?
The air conditioner continues running normally. The display only sends commands— it does not keep the system running.
4. How do I stop the air conditioner if the display fails?
Simply turn off the breaker supplying power to the air conditioner.
5. Can the display operate while plugged into USB-C?
Yes. The display can run from USB-C power directly or charge its internal battery.
6. How do I pair the wireless touchscreen with the air conditioner?
Open the Devices tab → tap "Start Scanning" → wait for the device to turn blue → press the ADD DEVICE button on the air conditioner.
7. Where should I install the temperature sensor?
Inside the air filter area at the return inlet. It is calibrated for short-range use and should not be extended to other cabins.
8. What duct size does the system use?
The supply uses standard 4-inch flexible/insulated marine ducting.
9. How large should the return grille be?
A 12" × 12" return grille is recommended to ensure proper airflow.
10. Does the system need a soft-start device?
No. The variable-speed compressor always starts at its lowest draw, eliminating the need for soft-start units.
11. What size water hose does the system use?
¾-inch marine-grade hose for both inlet and discharge.
12. Where should the seawater pump be installed?
Below the waterline. The supplied pump is not self-priming and must remain flooded.
13. Can the seawater pump be installed far away?
Yes—up to 50 feet away, provided hose runs are secure and properly routed.
14. How should I route the condensate drain?
Gravity drain only. Ensure a continuous downhill run without sags where water can pool.
15. What power wire size should I use?
Marine-grade 4/2 AWG duplex wire is recommended, depending on run length. Undersized wire can overheat and cause damage.
16. Does the system need its own dedicated power circuit?
Yes. Do not share the circuit with other loads.
17. How do I set a power consumption budget?
On the display, open the Budget screen → enable budgeting → select your limit (50–800 Ah) using the scroll wheel.
18. What does Energy Auto mode do?
The compressor automatically adjusts its speed based on the difference between ambient and target temperature or humidity to optimize power efficiency.
19. What refrigerant does the system use?
R134a by default, but the system is also compatible with R1234yf if required by local regulations.
20. How do I reboot a frozen display?
Open the battery door and press the reset button. If still frozen, perform a full discharge by disconnecting the battery, USB-C, and display ribbon for 30 seconds, then reconnect.
21. Does the display automatically dim or sleep?
Yes. It enters power-save mode after 30 seconds of inactivity unless set to “never sleep” in the Display tab.
22. How often should I perform maintenance?
Clean the air filter regularly, inspect the sea strainer for debris, and periodically open the pump to clear blockages.
23. What type of power source can charge the display?
Any USB-C charger. Charge in a ventilated area away from flammable materials.
24. Can I dispose of the system in regular trash?
No. Follow local electronic and battery disposal regulations and recycling programs.
25. What warranty does the SeaAir system include?
A 1-year limited warranty to the original purchaser covering defects in materials and workmanship.
