Nuaire Group COOKERXBOX Installation And Maintenance Manual

1.0 Introduction
Nuaire's COOKERXBOX units are designed to provide
whole home ventilation with heat exchange heat
recovery.
A typical installation could be in the kitchen area,
providing the most effective extract performance and
taking advantage of the recoverable heat from cooking
etc. In addition subsidiary extract from a bathroom or
utility rooms can be configured.
The case is constructed in pre-painted galvanised steel.
The unit shall incorporate two backward curved centrifugal
impeller fan units for:
1). Continuous central input with optional boost (see 4.2).
2). Continuous multiple extract from "wet" areas with
automatic boost from internal thermostat and/or optional
remote switches (see 4.0).
There are four ducting connections to be made from the
sides of the unit. The four ducting positions on the top of
the unit can be employed for other installation options.
1) Fresh air input to unit (100mm dia).
2) Exhaust air to outside (100mm dia).
3) Fresh air supply to dwelling (100mm dia).
This duct should terminate via a discharge
diffuser located centrally within the dwelling.
4) Extract air from bathroom/en-suite
(100mm dia).

2.2 Handing
Viewed from the front, the supply air to the dwelling is to
the left hand side of the unit, and the exhaust air to outside
is to the right hand side (see fig 1a). If the unit is to be
installed the opposite way, please see 3.0 converting to
opposite hand.
2.3 Duct connections
Duct connections can be made from either the sides of the
unit or the top. The side connections are used to enable the
ducting to run across the top of the wall units.
Note: the distance between the underside of the unit and
the supporting surface for the cooking vessel must be at
least 650mm. If using the side connections prevents this
dimension being met then either the wall units should be
raised, or the top connections should be used.
