2. מידע בטיחות
Adherence to the following safety guidelines is crucial for preventing property damage, personal injury, or death. Installation and service must be performed by a qualified professional.
- בטיחות חשמל: This unit requires a dedicated electrical circuit. Ensure the power supply matches the unit's requirements (110-120 volts, 3.5 kW, 29 Amps). A 1 x 2-POLE 30 AMP breaker is required and is NOT included. All wiring must comply with national and local electrical codes.
- לחץ מים: The maximum operating pressure is 150 PSI. Ensure your water supply pressure is within this limit. Installation of a pressure regulating valve may be necessary if pressure exceeds this.
- טמפרטורת מים: The unit can heat water up to 122°F (50°C). Exercise caution to prevent scalding, especially when used by children or individuals with reduced physical, sensory, or mental capabilities.
- מיקום ההתקנה: Install the unit in a location protected from freezing temperatures. Ensure adequate ventilation and accessibility for maintenance.
- דְלִיפָה: Regularly inspect the unit and connections for any signs of water leakage. Address any leaks immediately.

4.3 חיבורי חשמל
This unit requires a hard-wired electrical connection. Ensure the power is OFF at the main breaker before beginning any electrical work. Connect the unit to a dedicated 110-120 volt circuit with a 1 x 2-POLE 30 AMP breaker. Use 1 x 12 AWG wire for connections. If you are unsure about electrical wiring, consult a licensed electrician.
5. תפעול
Once installed and connected, the Thermoflow Mini Tankless Water Heater provides instant hot water. There is no need to preheat. The unit features a smart modulation system that adjusts power automatically based on flow rate and temperature settings to maintain a stable output temperature between 95°F and 122°F.

5.1 בקרת זרימה מתקדמת
The unit includes an exclusive Advanced Flow Control feature. If the demand for hot water temporarily exceeds the unit's capacity, you can slightly reduce the water flow at the faucet to maintain a consistent hot water temperature. This helps prevent sudden temperature drops during peak usage.

6. תחזוקה
תחזוקה שוטפת מבטיחה ביצועים אופטימליים ואורך חיים של דוד המים שלכם.
- בדיקה תקופתית: Annually inspect all water connections for leaks and tighten if necessary.
- ניקוי: The exterior of the unit can be wiped clean with a damp בַּד. אין להשתמש בחומרי ניקוי שוחקים.
- בדיקת משקעים: If water flow decreases or temperature fluctuates, check for sediment buildup in the inlet filter (if applicable) and clean as needed.
- חורף: If the unit is in an area prone to freezing and will not be used for an extended period, drain the unit completely to prevent damage from freezing water.
