Setup and Installation
1. Site Selection
Choose a well-ventilated outdoor location, away from direct sunlight and obstructions. Ensure sufficient clearance around the unit for proper airflow (refer to specific clearance requirements in the detailed manual). The surface should be level and capable of supporting the unit's weight.
2. Mounting the Unit
Place the anti-vibration supports under the heat pump's feet to minimize noise and vibration. Secure the unit if necessary, following local guidelines.
3. Plumbing Connections
Connect the heat pump to your pool's filtration system using the provided PVC connectors (Ø 50mm 1½''). Ensure all connections are watertight. The heat pump should be installed after the filter and before any chemical injection points.
4. Electrical Connections
All electrical work must be performed by a qualified electrician in accordance with local codes. Ensure the correct voltage and circuit breaker size are used. The unit requires a dedicated power supply.
5. Condensate Drainage
Attach the condensate drain hose to the designated outlet on the unit. Route the hose to a suitable drainage point, ensuring it has a continuous downward slope to prevent water accumulation.
6. Control Panel Extension
If desired, use the 10-meter wired control extension to relocate the LED control panel for easier access. Connect the extension cable securely between the main unit and the control panel.
Operating Instructions
1. Initial Startup
Before starting the heat pump, ensure your pool's filtration system is running and water is circulating through the unit. Turn on the power supply to the heat pump.
2. Using the LED Control Panel
The integrated LED control panel allows you to set the desired water temperature, select operating modes, and view system status. Refer to the detailed manual for specific button functions and menu navigation.
3. Wi-Fi Connectivity and Smartphone App
The POOLEX Silverline Inverter FI 120 features Wi-Fi connectivity for remote control via a dedicated smartphone application. Download the app from your device's app store and follow the in-app instructions to pair your heat pump. This allows for simplified operation and monitoring from your smartphone.
4. Temperature Setting
Set your desired pool water temperature using the control panel or smartphone app. The inverter technology will automatically adjust its power output to efficiently reach and maintain the set temperature.
5. Optimal Performance
For optimal heating efficiency, ensure your pool is covered when not in use, especially overnight. The heat pump's multi-frequency compressor and variable fan contribute to its high Coefficient of Performance (COP) and quiet operation.
Maintenance
1. Regular Cleaning
Periodically clean the exterior of the heat pump with a soft, damp cloth. Ensure the air intake and exhaust grilles are free from debris, leaves, and other obstructions to maintain proper airflow.
2. Water Chemistry
Maintain proper pool water chemistry as recommended by your pool professional. Imbalanced water can affect the longevity of your heat pump's components.
3. Winterization (Off-Season Storage)
Before the cold season, it is crucial to properly winterize your heat pump to prevent damage from freezing. This typically involves draining all water from the unit, disconnecting plumbing, and covering the unit with the provided protective cover. Consult the detailed manual for specific winterization procedures.
4. Professional Inspection
It is recommended to have a qualified technician inspect your heat pump annually to ensure it is operating efficiently and to identify any potential issues.
