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 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. Be very mindful that internal filters 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 specified.

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 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.

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 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.

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 fitted, the condensate 

drain outlet must be fitted with a ‘P-Trap’ and have a 

minimum fill 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 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 INDOORS MUST HAVE 

DRAIN TRAYS UNDER THE COMPLETE UNIT.
