CSA 22.2

I - Shipping And Packing List

Package 1 of 1 contains:
1 -  MiniCore Ventilator Assembly

II - Shipping Damage

Check unit for shipping damage. Receiving party should 

contact last carrier immediately if shipping damage is 

found.

III - General

These instructions are intended as a general guide and 

do not supersede local codes in any way. Authorities 

having jurisdiction should be consulted before installation.

IV - Requirements

When installed, the unit must be electrically wired and 

grounded in accordance with local codes or, in the 

absence of local codes, with the current National Electric 

Code, ANSI/NFPA No. 70.

V - Application

MiniCore ventilators are used as a stand alone indoor 

option for heat recovery ventilators used in light 

commercial applications. These ventilators conserve 

energy by transferring heat energy across two opposing 

air streams using a polymer core heat exchanger. This 

process works in the summer by rejecting the heat energy 

from incoming intake air and in the winter by conserving 

the heat energy from the exhaust air, allowing outdoor 

ventilation rates to be increased by factors of three

 

or 

more without additional energy penalty or increase in size 

of the heating or air conditioning systems.

VI - Rigging Unit For Lifting

1.  Maximum weight of unit is:

VII - Installation

When choosing a location to mount the MiniCore 

Ventilator take into consideration ductwork layout as well 

as access for future filter changes and Core cleaning. See 

maintenance section on

2.  Remove carton.
3.  All panels must be in place for rigging.
4.  Lift unit into place with a winch or jack.

WARNING

Electric shock hazard. Can cause injury or death. 

Before attempting to perform any service or 

maintenance, turn the electrical power to unit 

OFF at disconnect switch(es). Unit may have 

multiple power supplies.

CAUTION

Danger of sharp metallic edges. Can cause injury. Take care 

when servicing unit to avoid accidental contact with sharp 

edges.

Figure 1

Normal installation of the MiniCore Ventilator unit is 

hanging from the 4 corners using the included hanging 

kit though the units can be mounted on a shelf or on the 

floor of a mechanical room using optional floor vibration 

isolators.
