ACS – Slim Line System Installation

Installation Overview

The ACS – Slim Line System should be installed by an experienced HVAC mechanical contractor

and a licensed electrician. The installation consists of the following four phases:

• Phase 1: Removal of the existing 2” mechanical lters.

• Phase 2: Installing the ACS – Slim Line components.

• Phase 3: Connecting the ACS – Slim Line components and system power.

• Phase 4: Testing the system.

Installing the SecureAire ACS – Slim Line System

Phase 1: Removal of the existing 2” mechanical lters

STEP 1: Ensure that you have measured the existing mechanical lters and have ordered the

appropriate size SecureAire ACS – Slim Line Filter Units.

STEP 2: Check the existing 2” racking system for damage and/or adjustments and perform

the necessary changes.

STEP 3: Plan and install blank-os if and where required.

Phase 2: Installing the ACS – Slim Line Components

The ACS – Slim Line System has been designed for easy installation. Basic mechanical tools and skills

are needed to install the ACS – Slim Line Filter Units, Power Supply, and Safety Interlock Door Switch

components.

STEP 1: Remove the ACS – Slim Line lters and components from their shipping boxes. Be careful

and utilize the lter frame as grasp points.

STEP 2: Slide the rst ACS – Slim Line lter (Item B) into the 2” U-channel. The rst unit is the one

that contains the “Protection Plate” (Item A) which has been factory installed.

STEP 3: Slide the remaining ACS – Slim Line Filter(s) (Item C) into the U-channel and gently push them

together. The last lter unit has the “Connection Plate” (Item D) already attached and is identied

by the high voltage wires attached. (You may have more than 2 wide ACS – Slim Line Filter

Positions, slide each one until you reach the last.)

Refer to Figure 1 as needed.

ACS – Slim Line System Installation

Phase 3: Powering Up the ACS – Slim Line System

Basic electrical skills are needed to power up the ACS – Slim Line System to the SCM-300C Power Supplies,

Safety Interlock Door Switches, and building automation system.

Once the ACS – Slim Line units, SCM-300Cs, and safety interlock switches are interconnected, the 120 VAC

or 240 VAC power should be connected. A certied and licensed electrician must complete this part of the

installation.

STEP 1: Connecting the Connection Plate (Item D) wires to the SCM-300C Power Supply

• Unit C as the Connection Plate (D) with wires pre-installed at the factory.

• The (+) and (–) wires need to be connected to the proper terminals on the SCM-300C Power Supply

(included). The front wire should be negative (–) and the back wire should be positive (+).

Phase 3, continued

STEP 2: Locate and mount the System Control Module (SCM-300C) within 12 feet of the Connection Plate,

which is now attached and located at the end of each row of the ACS – Slim Line.

STEP 3: Install the included SPDT (120 Vac) Safety Interlock Door Switch to all access doors and wire the

input power line voltage circuit to interrupt the circuit so that the ACS – Slim Line Units become

de-energized should a door or access panel be opened. The input supply power is 120 Vac

50/60 Hz, single phase, 3-wire.

ACS – Slim Line System Installation

STEP 4: Install appropriate local building code compliant conduit between the Safety Interlock Door Switch,

the SCM-300C unit(s) and the high voltage wires traveling from the SCM-300C unit(s) to the

Connection Plate(s) of each row of the lter array.

The electrical rating of the SCM-300C is: voltage (V): 120 Vac, Current (A): 3/4 A, and Power (W): 21W

Should a 120 Vac power supply circuit not be available, please contact the factory for recommendations

on available transformers.

Each SCM-300C unit is equipped with an Auxiliary Blower Contact Circuit (yellow and purple wires),

which may be used to de-energize the system if the air handler fan is not operating. This step is

recommended as an energy conservation method but is not required.

NOTE: If the Auxiliary Blower Contact Circuit is not used, simply wire nut together both the yellow

and purple wires.

Option 2: Direct Contact to SCM-300C

www.secureaire.com | Proudly made in the U.S.A. | ACS – Slim Line-Rev A 7

STEP 5: If required, the SCM-300C unit(s) can communicate directly to a Building Automation System.

Simply connect the chosen control wiring to the SCM-300C unit(s) through the optional

communication ports (Figure 3).

Phase 4: Test the system

Once the connections have been made in Steps 4 and 5, turn on the power and close the AHU door

to check the SCM-300C(s) for a GREEN light normal-operating signal.

Your installation is now complete!

1. Make sure no metal, including metal shavings

or screws, gets placed or lodged in the ACS –

Slim Line units as this can create an electrical

short and cause a failure condition, thus

preventing the system from proper operation.

2. Should the SCM-300Cs be subject to outside

weather conditions a NEMA 4 rated enclosure

box is recommended.

3. An Air Unit Access Door is recommended to

provide clearance for installation, service or

lter change-outs of the ACS – Slim Line Units.

4. A minimum of 1” of clearance must be

maintained from any metallic objects or

surfaces from the ACS – Slim Line units and

racking system.

5. All electronic equipment should have proper

earth grounding wires in place prior to turning

on any electrical circuits.

6. In inclement weather conditions, it is strongly

recommended that a Mist Eliminator or

Hydrophobic Pre-Filter be used upstream of

the ACS – Slim Line System.

7. The ACS – Slim Line is an electrically enhanced

air purication device and should not be

exposed to direct contact with water (rain,

snow, etc.). Relative humidity rates of up to

95% are acceptable but direct contact with the

elements are not.

Important Notes:

ACS – Slim Line System Installation

www.secureaire.com | Proudly made in the U.S.A. | ACS – Slim Line-Rev A8

Startup and Maintenance

The ACS – Slim Line system was designed for easy installation and maintenance. Once the ACS – Slim Line

system has been installed and properly connected the system is ready to run. Once the ACS – Slim Line is

turned on, a constant green light appears, and operation is underway. It is that simple.

Filter media change-outs: Filter media change-outs

are solely based upon airborne contaminant loading

from the environment that the system has been

installed in. SecureAire lter media typically lasts

2-3X longer than equivalent MERV rated mechanical

lters. The replacement of SecureAire lter media is

accomplished through the removal of the bottom

access panel door and lter stabilizer bar which are

appropriately labeled. Simply release the bottom panel

with a at-head screwdriver, carefully remove lter

stabilizer bar and then the loaded lter media, and

replace it with the new media.

Maintenance: While no further maintenance is

specically required, it is advised to occasionally check

for dirt buildup on the units. If dirt buildup does occur

it can simply be blown o with an air gun while units

are not energized.

Designed for safety: Each SCM-300C is designed to monitor all power parameters. If the current, voltage,

and temperature level increases to an unacceptable level the SCM-300C will turn itself o. All other

SCM 300Cs will not be aected.

If an ACS – Slim Line System is going to be accessed, the amount of time to be allowed for discharge after

removing power and before accessing the grid assembly is approximately 30 seconds. It is recommended

that verication of high voltage be performed (using a high-voltage meter or other suitable indicator) prior

to working on or near the grid assembly.
