Safety
4 Armcor_XCM–Compact Multiow ERV Installation and Operation Manual 2021

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.
Location of Equipment
Minimum Access Requirements
for Maintenance
• The unit must be mounted so that sufcient 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 lters via access doors as required.
• Unless otherwise specied 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. Be very mindful that internal lters need to be
accessed regularly for cleaning.
• 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 specied.
Noise Levels
• 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 wafe pad to be
used under the base frame and exible couplings be
tted to the supply and return ducts to reduce any
vibration transfer.
Fresh Air Inlet and Exhaust Air
Outlet
• 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 airow 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 tted with a cowl or other suitable means of
weatherproong.
• The exhaust discharge should be directed away from
any openable windows.
Drainage
Due to different moisture content levels of incoming
fresh air, heat exchange equipment can be subject
to some condensation. It is recommended that units
located in ceiling spaces or plant rooms are installed
with external drain trays under the complete unit.
Where an internal drain tray is tted, the condensate
drain outlet must be tted with a ‘P-Trap’ and have a
minimum ll of 20mm per metre length.
• 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 tting 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 INDOORS MUST HAVE
DRAIN TRAYS UNDER THE COMPLETE UNIT.
Armcor_XCM–Compact Multiow ERV Installation and Operation Manual 2021 5

Installation Instructions
Unpacking and Inspection
• The unit was tested and inspected prior to packing and
was in perfect condition at the time at time of despatch.
• The unit should be inspected upon delivery for
possible external damage incurred during transport.
If damage is evident it should be noted on the freight
docket and contact is to be made with the Armcor
Air Solutions sales ofce. A claim should be lodged
with the shipping company within 3 days if goods are
damaged or incomplete. No claims will be recognised
after this date.
• IF MAJOR DAMAGE IS APPARENT, DO NOT INSTALL UNIT
ON TO SITE WITHOUT PRIOR APPROVAL FROM ARMCOR.
• Check unit rating plate to ensure the correct unit
matches the job specications.
Unit Handling
• Protective crating or packaging and the pallets
should not be removed until the unit is at the point of
installation.
• When removing packaging or crating, be careful not
to damage, scratch or dent the unit.
• After removal of packaging, all removable access panels
should be opened to inspect for unit internal damage.
Lifting with a Crane
• SAFETY – when installing or working on equipment,
always adhere to safety codes and guidelines.
Wear safety goggles, work gloves, work boots and
protective clothing.
• All units should be lifted into position using SLINGS
and not CHAINS. (Chains may damage exterior nish
on the fan unit).
• Where units must be craned into position, installers
must check unit weight is within the safe tolerance of
the working capacity of the crane.
• Prepare for lifting with spreaders as you would do
with lifting air conditioning equipment.
• When lifting equipment never stand under the load.
• Beware of lifting equipment on to roof areas in windy
conditions. Only lift when weather conditions are
favourable.
Lifting with a Forklift
• Exercise extreme caution when lifting with a forklift.
Do not exceed the height limit of the forklift and
never allow the forklift forks to make contact directly
with the bottom panel of the unit.
• Make careful consideration of the unit’s centre
of gravity and distribute the weight equally
on both forks. Test load to see if the weight is
equally distributed. Do this by lifting the unit a
few centimetres off the ground level and checking
stability before lifting any further or before
transporting the unit.
Suspending the Unit
• Before suspending the unit, check the supporting
beams have sufcient load carrying capacity to
support the weight of the unit. Equipment is supplied
with brackets to support the unit.
• We recommend that all compact multiow units
be suspended or supported with suitable mounting
springs to eliminate the transmission of vibration.
• At each corner of the unit, there are 6mm bolts and
captive nuts. The bolt can be removed and a hanging
bracket attached to this xing point if required.
Hanging Bracket Fixing
• Remove 6mm corner bolt.
• Align bracket and re-t corner bolt.
• Secure with two additional self-drilling screws
through base

Equipment Connections
Ductwork
• Air distribution ductwork must be designed to allow
for the specied air ow without excessive pressure
levels. The unit should be situated as close as
possible to the point of use to prevent unnecessary
long runs of ductwork.
• Sheet metal ductwork is recommended for use with
all Armcor Air Solutions equipment.
• Ducts should be insulated in accordance with BCA
Section J-5.
• Fan inlet conditions can affect the fan performance,
particularly where duct bends cause a non-uniform
ow and swirl at the inlet. To reduce losses due
to fan systems effect, adequate length of straight
duct between any elbow and the fan inlet should be
provided or turning vanes used in the elbow.
• Poor fan outlet conditions will also affect the fan
performance. We recommend a minimum of 1000mm
of straight duct directly after the fan outlet.
Filters
• 50mm panel lters are a minimum recommendation
for all equipment.
• Filters must be tted to fresh air and/or return air.
• If the lters in the unit are not accessible for cleaning,
the installing contractor is responsible to incorporate
lters in the ductwork system external to the unit.
• It is recommended that temporary disposable lters
are used during construction and commissioning.
IMPORTANT: NEVER OPERATE A UNIT WITHOUT FILTERS
FITTED TO THE RETURN AND FRESH AIR INTAKES.
WARRANTY IS VOID IF THE FILTERS ARE NOT FITTED
AND REGULARLY CLEANED OR REPLACED.
Electrical Requirements
• The power requirement and voltage are detailed on
the equipment technical specications (available
on our website armcor.com.au) and are on the
identication/serial no. plate attached to each unit.
• An electrical diagram is attached to the electrical box
on the unit.
Mains Power Supply and Fusing
• A single-phase power supply rated at 240v (+/- 5%)
50Hz or a 3-phase power supply rated at 415 volts is
required to operate the unit within manufacturer’s
tolerance. Check the name plates for correct voltage.
• We recommend an isolator be mounted externally
to the unit (not supplied) and a suitably sized
circuit breaker mounted back at the distribution
board to provide local isolation during service and
maintenance periods.
• Main cables and control circuit wires are to be
connected as per wiring diagram.
• All wiring must comply with relevant local wiring
regulations.
• The units require a main circuit breaker or HRC fuse
capable of handling the full load of the unit and
selected in accordance with SAA Wiring Rules.
• All wiring is to be independently colour coded.
• Single phase fan motors are internally protected and
there is no need for external overloads.
