IMPORTANT SAFETY INFORMATION

 

           

WARNING

ARC FLASH AND ELECTRIC SHOCK HAZARD

Arc flash and electric shock hazard. Disconnect all electric 

power supplies, verify with a voltmeter that electric power is off 

and wear protective equipment per NFPA 70E before working 

within electric control enclosure. Failure to comply can cause 

serious injury or death.

Customer must provide earth ground to unit, per NEC, CEC and 

local codes, as applicable.

Before proceeding with installation, read all instructions, 

verifying that all the parts are included and check the nameplate 

to be sure the voltage matches available utility power.

The line side of the disconnect switch contains live high-voltage.

The only way to ensure that there is NO voltage inside the unit 

is to install and open a remote disconnect switch and verify that 

power is off with a volt meter. Refer to unit electrical schematic.
Follow all local codes.

 

RISK OF ELECTRIC SHOCK OR EQUIPMENT DAMAGE 

Whenever electrical wiring is connected, disconnected or 

changed, the power supply to the ERV and its controls must 

be disconnected. Lock and tag the disconnect switch or circuit 

breaker to prevent accidental reconnection of electric power.

RISK OF CONTACT WITH HIGH SPEED MOVING PARTS. 

Disconnect all local and remote power supplies, verify with 

a voltmeter that electric power is off and all fan blades have 

stopped rotating before working on the unit.

Do not operate this unit with any cabinet panels removed or 

prior to assembly of the modules

RISK OF DAMAGE TO ENTHALPIC CORES

Whenever working within the ERV cabinet, protect the enthalpic 

cores from accidental damage. The core media is subject to 

damage from dropped tools or other foreign objects. 

RISK OF CONTACT WITH HOT SURFACES

The blower motor and other electrical components are extremely 

hot during operation. Allow sufficient time for them to cool 

before working within the unit cabinet. Use extreme caution and 

wear protective gloves and arm protection when working on or 

near hot blower motors and electrical components.

This unit is intended for general ventilating only. Do not use to 

exhaust hazardous or explosive materials and vapors. Do not 

connect this equipment to range hoods, fume hoods or collection 

systems for toxics.

This unit is for ventilating finished structures only. It is not to 

be used until after all construction has been completed and 

construction debris and dust are cleaned from the Occupied 

Space. 

This equipment is to be installed by following Industry Best 

Practices and all applicable codes. Any damage to components, 

assemblies, subassemblies or the cabinet which is caused by 

improper installation practices will void the warranty.
