1.0 XBOXER XBC UNIT ACCESS CONCEPTS
In this product range, several unique concepts have been implemented
with a view to simplifying the installation design.
1. The unit configuration is such that the supply and discharge
connections are positioned on the unit centreline.
The corresponding Intake and Extract connections may be positioned
on either side of the unit, allowing greater flexibility in the layout of
ductwork in the space. (see Fig 2a) with the blanking panel re-
positioned to suit.
2. The standard Ecosmart XBC unit configuration is shown in Fig 2b.
Unit handing information will not be requested for this range,
and units will be supplied in this format as standard.
3. The unit must be installed with at least 600mm clearance from a
wall / barrier on the control side of the unit. With this absolute
minimum clearance, the unit may be connected to the power supply
and control connections. (Note: - cable connections must allow for
the relative movement when the control is re-positioned).
4. With this clearance, unit filters may be changed, and the fans coils,
heat exchanger and condensate tray may be inspected and cleaned
if necessary.
5. The LPHW and Electrical heater settings, coil bleed and drain, and
all other control adjustments are similarly accessible (see Fig 1).
6. Side access, where possible, is preferred in all cases in terms of safe
working access to the equipment under the CDM regulations.
7. Note however, that access in the situation is difficult and additional
time should be allocated. For convenience it is preferred that
wherever possible, this minimum access provision is not adopted,
and it is recommended that a minimum of around 600mm clearance
(as stated in ADF 2010) is allowed.
8. Where these arrangements are not suitable, the Consultant’s and
Contractor’s project specific requirements will always be
accommodated where possible.
9. Bottom access only units. (Example code: XBC15-H-LCO BA).
Provides access to filters only (see fig 4).
Filter removal is not available from the sides on these units.
Bottom access units must be installed with the following
minimum clearance below the units.
XBC15 = 225mm, XBC25 = 300mm XBC45 = 360mm.
Note: Bottom access is not available on XBC55 or XBC65 units.
