2.0 INTRODUCTION

The information contained in this document provides details of 
installation, operation and maintenance for installers and users of the 
XBOXER XBC Supply and Extract Ventilation Unit with Heat Recovery.

This supply and extract air handling unit range comprises an 
combination of high efficiency centrifugal fans with EC motors, a 
Counterflow design plate heat exchanger, filters, optional heaters 
(LPHW and Electric) and a casing with high mass acoustic treatment.

A range of matched, close coupled attenuators with a similar 
construction method to that of the unit is available. The attenuators 
can be flipped for positioning on the left or right of the fan unit  
(Figure 1) allowing flexibility for duct layout.

Attenuators are available in 1050, 1250 and 1600mm lengths and a 
matching attenuator flange is attached to the fan unit. 

General information regarding performance and specifications for 
the equipment may be obtained from our Technical Literature, and/or 
project specific documentation.
