Installation Guide for Trane QuikBox Air Filter Enclosure

Quick Guide

The Trane QuikBox air filter enclosure is designed for residential HVAC systems. Key requirements for installation include placing the unit on the return air side of the furnace or air handler and ensuring a minimum of 28 inches of clearance in front of the enclosure for filter access. Do not install the unit in the discharge air stream or where it will be exposed to UV light.

Product Overview

The QuikBox system consists of three main components:

• Enclosure: 22-gauge painted steel with internal insulation.
• Filter: Collapsible 5-inch, electrostatically charged media, available in MERV 11 or MERV 13 ratings.
• Access Door: Fully insulated door with quarter-turn latches for easy filter access.

Pre-Installation Requirements

Before beginning the installation, ensure the following conditions are met:

• Location: The enclosure must be mounted in the return air duct on the entering air side of the central forced-air furnace or air handler.
• Orientation: The face of the filter must be at a right angle to the air stream.
• Clearance: Allow a minimum of 28 inches of clearance in front of the enclosure to permit filter removal.
• UV Protection: Do not install the air cleaner where the filter can be exposed to UV light, as this can cause plastic material to deteriorate.
• Humidifiers: If using atomizing spray type humidifiers, they must be installed on the supply side, away from the filter.

Installation: Bottom Mount

Follow these steps to install the enclosure on the bottom of a furnace or air handler:

1. Remove the access door by rotating the two quarter-turn latches. Remove the filter and set it aside.
2. Position the furnace or air handler on a protective pad on the floor with the bottom facing up.
3. Install the self-adhesive gasket material onto the flange of the discharge-air side of the filter enclosure. The gasket must be placed toward the outside edge of the flange.
4. Position the filter enclosure on the bottom of the unit with the gasket against the unit. Align the rear and sides of the enclosure with the unit. Note that the front of the enclosure will not align flush with the front of the unit.
5. Ensure the front of the filter enclosure is facing the front of the unit.
6. Securely attach the filter enclosure to the unit using heavy-duty self-tapping sheet metal screws (recommended: #12-14, 1/2 inch length, hex washer head).

Maintenance and Replacement

The maintenance schedule depends on the amount of air passing through the filter and the amount of dust, pollen, or smoke in the air. The following schedule is an estimate:

• Continuous Fan (Dusty): 1-2 Months
• Continuous Fan (Normal): 3 Months
• Auto Fan (Dusty): 3 Months
• Auto Fan (Normal): 6 Months
