Equipment Connections

Ductwork

• 

Air distribution ductwork must be designed to allow 

for the specified air flow 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 

flow 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 filters are a minimum recommendation 

for all equipment.

• 

Filters must be fitted to fresh air and/or return air. 

• 

If the filters in the unit are not accessible for cleaning, 

the installing contractor is responsible to incorporate 

filters in the ductwork system external to the unit.

• 

It is recommended that temporary disposable filters 

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 specifications (available 

on our website armcor.com.au) and are on the 

identification/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.
