5. Configuració i instal·lació
The RadonAway Air Flow Alarm is designed for straightforward installation on your radon mitigation system's PVC piping.
5.1 Muntatge de l'alarma
The alarm unit mounts directly onto the exterior of a 3-inch or 4-inch system pipe. Select a location on the pipe that is easily visible and accessible for monitoring and maintenance.
This image displays the RadonAway Air Flow Alarm Model 28421 attached to a radon system pipe. The clear casing reveals the internal components, including the red LED indicator light and the vane extending into the pipe, which detects air movement.
5.2 Vane Installation
A thin, field-trimmable vane is installed inside the pipe. This vane is designed to move with adequate air flow. Ensure the vane is correctly positioned and can move freely within the pipe without obstruction. Refer to the detailed instructions included in the product packaging for precise vane trimming and insertion.
5.3 Battery Installation/Activation
The unit is battery-powered. If the battery is not pre-installed, open the battery compartment, insert the provided battery, ensuring correct polarity. If pre-installed, remove any battery tab to activate the device.
6. Instruccions de funcionament
Once installed and activated, the RadonAway Air Flow Alarm continuously monitors the air flow in your radon mitigation system.
- Funcionament normal: When the radon system is operating correctly and there is sufficient air flow, the alarm will remain silent, and the red LED light will be off. The internal vane will be in a position indicating air movement.
- Condició d'alarma: If the air flow in the pipe drops below a critical level or ceases entirely (e.g., due to fan failure, blockage, or power outage to the fan), the alarm will activate. You will hear an alternating audible buzzer, and a bright, flashing red LED light will be visible.
- Avís de bateria baixa: The alarm will provide a distinct indication (e.g., a short beep or specific LED flash pattern) when the battery power is low, signaling that it needs to be replaced soon.
7. Manteniment
- Substitució de la bateria: When the low battery warning is active, replace the battery immediately with a new one of the same type. Refer to the battery compartment for specific battery type.
- Neteja: Periodically wipe the exterior of the alarm with a soft, dry cloth to remove dust. Do not use harsh chemicals or abrasive cleaners.
- Vane Check: Occasionally inspect the vane through the clear casing to ensure it is free from debris and can move without obstruction.
8. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Alarm constantly active (audible and visual) | No air flow in the pipe; Radon fan not operating; Pipe blockage; Vane stuck or improperly installed. | Check if the radon fan is powered and running.
