95MAX Port Specifications
The 95MAX Heat Recovery Ventilator (HRV) has been
designed to allow the installer to choose between two
possible positions on the cabinet for the INDOOR
EXHAUST (return from building) port. Illustrations in
this manual show standard (side mounted) port loca-
tion. The same specifications apply to both 95MAX
setups, regardless of which port position is selected.
Variable Port Location / Installation
(Model 95MAX only)
The exhaust return port collar is not factory installed.
Installer may choose either side mounted or alternate
top mounted port by simply removing one of the two
knock-out plates and attaching a port collar (supplied).
To remove knock-out plate, insert a utility knife into the
knock-out slits and trace them completely to puncture
protective film underneath. Then, cut the solid tabs
between the slits, using tin snips or side cutters, and
remove the knock-out plate. If any protective film still
blocks the opening, remove it now.
In order to make the 95MAX as space efficient as pos-
sible, the INDOOR supply and return ports are
converted from round to oval shape. Overall size of
the port remains the same. Simply bend a standard
duct fitting to the correct shape, and attach to the oval
port using the same method as for a round port.
95MAX Air Flow
Stale air enters the FRONT RIGHT side port. The air
will pass down the front half of the core, then up the
back half of the core and out the RIGHT REAR port.
Fresh outdoor air will enter the LEFT REAR port and
pass down the back half of the core. It will then pass
up the front half of the core, and out the LEFT FRONT
port. This unique configuration allows the air to actual-
ly travel through the core twice, making the 95MAX
almost as efficient as a double core unit.
