Section 6: Maintenance and Troubleshooting

6.0 Introduction

This section describes some of the standard maintenance practices that can be performed on the Mini Compact Outdoor Amplifier and tips to troubleshoot common customer issues.

6.1 Cooling System Maintenance

It is recommended that the cooling system be checked at least once per month. This involves visually inspecting the fan intakes to make sure that there is no obstructions over the intake. The Windows-based M&C program can be used to check the amplifier base plate temperature. The base plate temperature should normally not exceed a 20°C to 25°C rise above the current outside ambient temperature. If the base plate temperature exceeds this temperature rise, it is one indicator that the system’s airflow requires maintenance.

The heatsink fins in the exhaust path can be visually inspected for excessive dirt and debris buildup. If it appears there is excessive debris in the heatsink; the fan tray can be removed for easy cleaning.

Failure to keep the fans and heatsink clear of debris will void your warranty.

6.2 Fan Removal and Heatsink Cleaning

It is recommended to remove prime AC power from the amplifier when the fan tray is being removed. However, if necessary, the fan tray can be removed while the amplifier is operating. Caution should be used to make sure that no clothing or fingers are caught in the fan blades. Simply remove the four screws from the fan tray and the fan assembly can be removed from the bottom of the amplifier assembly.

The fans are connected to their power source by weatherized in-line circular connectors. A replacement fan with connector can be provided for replacement. While the fan tray is removed, the heatsink fins can be cleaned by spraying compressed air throughout the finned area. A can of dust remover spray such as that which is found at a computer or electronics shop will work fine. All debris should be removed before installing the fan tray.

6.2.1 Fan Replacement

The Mini Compact Outdoor SSPA utilizes a two-fan air intake tray, and any maintenance requiring replacement of the fans should use fan kit L207853-1. This kit replaces the entire fan tray assembly.
