Bullet Points:
Touchscreen Display: The 9KW pool heater features a high-definition touchscreen display for dual water temperature and timer operation, supporting temperature adjustment from 72°F to 122°F. The timer is adjustable from 1 to 15 hours.
304 stainless steel heating tubes: A 1000-gallon pool can be heated from 32°F to 72°F in 13.5 hours and from 32°F to 122°F in 30 hours. The galvanized steel casing is rust-resistant and resists rusting even in humid environments.
Professional Installation: The hard-wired design, performed by a licensed electrician, maximizes product lifespan and ensures safety. The 9KW heater is recommended for operation with a circulating water pump with a head of 14 to 21 meters and a water flow rate of at least 177 ft³/hr (5 m³/hr). If the pump and thermostat are not compatible, insufficient flow rate may cause the heating tube to dry out and damage it.
Automatic Cycling: The pool heater cycles on and off according to the preset temperature. When the water temperature reaches or exceeds the preset level, the pool thermostat automatically shuts off. Conversely, if the temperature drops below the preset level, the pool thermostat will automatically turn itself back on.
Scope of Application and Operation and Maintenance Guide: Suitable for 1000-gallon pools. Turn on the water pump first, then the thermostat. When shutting down the unit, turn off the thermostat first and wait for a short time (10 seconds to 1 minute) before turning off the water pump. Install a reliable leakage protection device, have it installed and debugged by a licensed electrician, and perform monthly inspections and maintenance.
Control Panel Operation Precautions:
1. Turn on the water supply and power, and perform water and electrical tests.
2. Turn the power switch to ON. The display will immediately show the water temperature and the unit will start.
3. To set the water temperature, first press the temperature button. Press the minus or plus button to adjust to the desired temperature. The temperature range is 72°F to 122°F.
4. To adjust the time, first press the time button. Press the minus or plus button again to adjust the time to the desired value. The time can be adjusted from 1 to 15 hours.
5. If the water flow indicator light is off, check whether the circulating water pump is on. If the pump is on, check whether the flow rate and head meet the requirements. If the flow rate/head are too low, replace the pump with a higher flow rate pump.
Four-fold protection:
1. Fuse protection: In extreme emergencies, the fuse quickly blows, immediately disconnecting the power supply.
2. Boil-dry protection: Two temperature sensors monitor the temperature at all times.
3. Water flow sensing system: Automatic shutdown for water shortage: The machine will not operate unless the water pump is activated, effectively preventing damage from water shortages and improper operation.
4. Temperature limit switch: Automatically shuts off when the temperature reaches a certain level and automatically activates when the temperature drops, preventing damage caused by overheating.
Note:
1. Do not use a booster pump with the thermostat; only a circulating water pump.
2. During installation, the inlet and outlet pipes must not be smaller than the designated inlet and outlet pipe connections on the thermostat. For example, if the thermostat's water inlet and outlet ports are pre-wired for 1.5-inch male threads, the inlet and outlet pipes are too thin, resulting in insufficient flow and excessive pressure inside the device, which can damage the thermostat and create safety hazards.
3. Thermostat Heating Principle: When power is applied, the heating element heats up, and cold water flows through it, gradually heating it to hot water.
Smoke and unusual noises: (Serious malfunction or safety hazard)
Possible Causes:
1. Circuit Overload or Short Circuit: Improper wiring, aging circuits, or abnormal voltages in high-power equipment can cause circuit overheating or even a short circuit. Symptoms: Smoke may be accompanied by a burning smell, and unusual noises may be caused by arcing or component burnout.
2. Heating Element Failure: Aging heating elements, dry-burning (insufficient water flow), or internal insulation damage. Symptoms: Localized overheating during heating causes smoke or unusual noises.
3. Water Circulation System Problems: Clogged water inlets and outlets, a malfunctioning water pump, or insufficient water flow, preventing the heating element from effectively dissipating heat. Symptoms: The device may emit smoke due to overheating, possibly accompanied by noises from abnormal water circulation.
4. Internal Component Damage Cause: Relay or capacitor failure, resulting in mechanical noise or electrical short circuit. Symptoms: The device may emit a harsh noise during operation, possibly accompanied by smoke.
Remedies:
1. Immediate Power Off: Quickly turn off the device power by unplugging it or disconnecting the circuit breaker. Purpose: To prevent further damage and avoid the risk of fire or electric shock.
2. External Inspection: Inspect the device casing for signs of burns, water leaks, or foreign objects. Caution: Do not disassemble the device yourself to avoid electric shock or damage to the internal components.
3. Electrical and Water System Inspection: Check the power cord or plug for loose or damaged parts, and check if the circuit is overloaded (e.g., if other high-power appliances are in use).
4. Water System Inspection: Check that the water inlet and outlet are unobstructed and the water pump is operating normally (you can manually touch the water pipes to feel the water flow).
