XEM - INSTALLATION & OPERATION MANUAL
It is important that the selected location for the equipment is
suitable and can adequately accommodate the unit physical
size, the unit weight and has safe and suitable access for
correct operation and future maintenance requirements.
The unit must be mounted so that sufficient space is
allowed for installation and service access. Maintenance
personnel need to gain access to all parts of the unit and
be able to remove components such as fans and filters via
access doors as required.
Unless otherwise specified the following minimum access
should be available:
• 800mm clearance for electrical connections
• 1200mm for all access doors on the unit or if no access
door is provided 1200mm from the front of the unit.
• Every proposed installation must be subject to an
engineered design by a mechanical services consultant.
Armcor Air Solutions is not responsible for installation of
equipment in situations for which the equipment was
not designed or specified.
• Do not locate equipment adjacent to sleeping quarters
unless background noise levels have been checked and
permitted by the appropriate authority.
• It is recommended that rubber supporting or vibration
absorbing pads be used to support the unit to minimise
any vibration being transmitted into the building
structure. We recommend waffle pad to be used under
the base frame and flexible couplings be fitted to the
supply and return ducts to reduce any vibration transfer.
• The location of the fresh air inlets must adhere to the
Australian Standards 1668.2
• The fresh air intake should be positioned clear of
any objects which could obstruct the airflow and be
a minimum distance of 6 metres from any exhaust
discharge ducts from this unit or any other adjacent
equipment. Refer to Australian Standards AS 1668.2
• The fresh air inlet and exhaust air outlet should be fitted
with a cowl or other suitable means of weatherproofing.
• The exhaust discharge should be directed away from any
openable windows.
• Equipment should be installed with a positive fall to
ensure water drains away freely through drain outlets.
Drain lines must be as large as or larger than the fitting to
which the line is being connected.
• All condensate drains must have a ‘P” Trap Fitted and have
a minimum fall of 20mm per metre length
• If drain lines are to be extended from the inside to the
outside of the building they must be extended beyond
walls of the building to eliminate the possibility of
damage caused by drain water running down the exterior
surface of the building wall
• When a drain is exposed to freezing temperatures or
subject to the formation of condensation, the drain
should be insulated.
IMPORTANT: ALL UNITS LOCATED IN PLANT ROOMS MUST HAVE DRAIN TRAYS UNDER THE COMPLETE UNIT
