MATERIALS NEEDED FOR COMMON HVAC INSTALLATIONS
1.
Section of 12" (14" for 1200/2000 units) diameter sheet metal (recommended) or flex duct. You
will need 3' to 6' for most installations.
2.
Section of 10" (14" for 1200/2000 units) diameter sheet metal (recommended) or flex duct. You
will need 6" to 24" for most installations.
3.
12" collar (14" for 1200/2000 units) for connection to return air duct.
4.
10" collar (14" for 1200/2000 units) for connection to fan return side of HVAC unit.
5.
4" by 18" (4" by 24" for 1200/2000 units) piece of sheet metal for Air Scoop. Or a prefabricated
damper. This is recommended to be installed with every unit.
6.
Sheet metal screws, duct tape or metal tape. 12 gauge electrical wire for power to unit.
7.
Thermostat wire.
INSTALLATION OF THE DUCTING
Select the proper location for the attachment of the inlet and discharge ducts. Try to keep a
minimum of 6 feet between the inlet and discharge openings. This will prevent the Pure Air
Systems’ filtration unit from recycling the same air. Cut the openings in the existing return air
duct. We recommend an air scoop be placed inside of the return air duct so that it directs air into
the inlet duct of your filtration system. You can use a damper as an air scoop. Make sure the
damper is angled to direct the air from the return air duct into the inlet duct of your filtration
system.
Use sheet metal screws, duct tape or aluminum tape to attach the duct sections to the collars on
the inlet of the unit and the air return. Make sure there are no air leaks. Repeat this same
procedure for the discharge duct. Make sure all connections are tight and taped.
ELECTRICAL WIRING
NOTE
: ALWAYS FOLLOW ELECTRICAL CODES FOR YOUR AREA.
We recommend a dedicated 15
amp service for all of our air filtration systems. The conduit connector is designed for EMT conduit
or Romex cable. Wire the black, white and green (ground) wires through the conduit connector to
the black, white and green wires inside the unit.
The 600HS unit requires 120 volt, single phase service. It uses a 1/3 HP 5 amp, capacitor start,
single speed motor. The system is designed to run 24 hours a day. You can control the 600HS
unit in two ways:
