Poly-Vent can be mounted to a variety of materials
including roll-formed rails, hat channels, square or
rectangle tubing, dimensional lumber, and many
other types of rails. The spacing for the rails is the
same, no matter what the application. The spacing
is also the same for either single or stacked applications.
See the chart above to determine the correct spacing

Mount the blower mounting rail to your structure's rails.
Because of the variety of rail types that may be used, no
fasteners are provided. Use appropriate fasteners for
your particular application.
Mount the blower mounting bracket to the blower
mounting rail using the 5/16" fasteners provided.
Insert the pv plug through the blower mount.
Bolt the poly-vent blower to the blower mount with the pv plug
between the blower and the mount using (4) 1/4" X 3/4" carriage
bolt, lock washer, and hex nut.
Slide the 3.25" hose clamp over the 3" X 5' flex tube leaving the
clamp loose temporarily.
Slide the 3" X 5' flex tube with the 3.25" clamp over the pv plug
and secure it in place by tightening the 3.25" hose clamp.

1. Thread the Poly-Vent film through the Poly-Vent frame.
USE CAUTION WITH THIS PROCEDURE. DO NOT LET THE POLY-VENT FILM SNAG ON OR CATCH ANY FRAME PARTS.
2. Center the Poly-Vent within the frame.
3. You can now install the air inlet flex tubing leading from the Poly-Vent blower.
MAKE SURE THE TUBE WITH THE

5. Next, insert the flex tube into the opening.
Make sure that there is no sharp wire
exposed that may puncture the Poly-Vent
tube.
1. Once you have located the correct location
for your flex tube connection, peel off the
backing from one gasket and apply it to the
clean dry plastic.
2. With a sharp utility knife, carefully cut out
the center portion of the plastic, being sure
to cut through the top layer only.

3. Remove the paper backing from the second gasket.
Carefully fold in half -- being very careful not to let the
adhesive make contact with itself -- and slip through
the hole just cut.
4. Align the inside gasket with the outside gasket, and
press together. As a safety measure, it is a good idea to
take an office stapler and staple the two gaskets together.

BASIC POLY-VENT OPERATION - PVII (Single-Stage Inflation)
20
Thermostats for the Poly-Vent system should be mounted approximately centered between each sidewall and centered from
front to rear of the structure. They should be mounted at eye level. However, some growers prefer to mount thermostats at
bench height.
Initial start-up: PVII Two Stage Poly-Vent
When inflating the Poly-Vent for the first time - before wiring the thermostat - turn on the blower. Moving from one end to the
other, manually help the Poly-Vent tubes up so that they do not twist.
The included wiring diagrams should be used to wire the thermostat into the system. Note that the wiring circuits more resemble
a "heating" circuit than a "cooling" circuit. This is the correct way to wire your thermostat. Please wire exactly as shown for
correct results.
With the Poly-Vent deflated, slowly turn the thermostat to a higher temperature until the blower is activated. If the system is
operating properly, the blower will activate and inflate the PVII system.
After the Poly-Vent has been successfully inflated, check for proper complete inflate/deflate cycle operation.
Now adjust the thermostat to the desired temperature to be maintained in your structure.
NOTE: If you have a BUBS (Back-Up Blower System) the BUBS is not generally wired to the thermostat so that if it is activated,
the Poly-Vent will remain inflated and will not cycle again until the power is restored.
NOTE: THIS BASIC POLY-VENT OPERATION PAGE IS FOR PVII (SINGLE-STAGE) SYSTEMS ONLY.
IF YOU PURCHASED A PVIII (TWO-STAGE) SYSTEM, SEE THE FOLLOWING PAGE FOR THE
CORRECT BASIC POLY-VENT OPERATION.
