MiniCore

Energy Core

Annual inspection of the energy recovery core is 
recommended. MiniCore units ventilating smoking 
lounges and other non-clean air spaces should have 
energy recovery core inspections more often based 
upon needs. 

Accessing the energy recovery core - 

Disconnect 

the power to the MiniCore. Remove access panel.

Removing the energy recovery core - 

Once the 

energy core access doors are removed, the core can be 
pulled from the housing. To replace the core, reverse the 
procedure.

Recommended cleaning procedure -

 First, remove 

the energy recovery core by following the instructions 
on this page.

Once the core is removed, gently vacuum the surfaces 
of the core to remove the dirt and debris that has 
accumulated. 

Frequency of cleaning - 

A regular cleaning cycle 

must be established for the energy recovery core in 
order to maintain optimum sensible and latent energy 
transfer. In reasonably clean environments such as 
schools, offices or retail stores, the energy recovery core 
should be inspected annually and cleaned as needed.

Failure to follow a regular cleaning cycle for the energy 
recovery core can result in significant energy transfer 
performance losses.

WARNING

Do not wash, soak in water or use detergents and 
cleaners on the core. This will result in a damaged 
core.

Optional EC Motor

Features

Soft start

 – All motors 

feature soft-start 
technology which 
eliminates inrush 
current at start-up. 
The motors will reliably 
start at any speed 
setting.

Overload protection

 – If the motor becomes 

overloaded, it will automatically reduce its speed until it 
is no longer overloaded. This means that the motor will 
never operate in the “service factor” which is possible 
with many AC motors.

Locked rotor protection

 – If the motor ever encounters 

a locked-rotor scenario, the motor will automatically 
shut itself down. It will try to restart up to 3 times, and if 
after the 3rd time the motor will still not rotate, the motor 
will not attempt to start again until power is cycled.

Thermal protection

 – The motors have a one-shot 

fuse thermal protector. This is meant to protect the 
motor from a severe temperature rise. With the motor 
controller’s ability to software limit the speed, the fuse  
is used as a last resort to prevent a fire. 

RPM measurement

 – The motors have a small shaft 

extension on the end of the motor to measure motor 
RPM with either a contact or optical tachometer.

Operation and Wiring - Potentiometer Dial

These motors feature a potentiometer dial on the motor 
for speed adjustment. A small screwdriver can be used 
to make the speed adjustment. To increase the speed, 
rotate the dial clockwise. To decrease the speed, rotate 
the dial counterclockwise.
