D) Installing your System
Install the dryer where the ambient air is as clean as possible and where the air temperature will never exceed
the dryers temperature limits.
Connect the Inlet (1) and Outlet (2) compressed air lines to the valve housings marked Inlet and Outlet, ensuring
the protective dust covers on the Desiccant Air Dryer are removed prior to connection.
Ensure the Desiccant Air Dryer is protected with the correct pre- and after filtration with the flow directional
arrows correctly aligned with the dryers flow path.
It is recommended that each dryer bank has its own independent filtration. Size 0132G filters should be used on
banks of up to and including 5 columns; size 0240G filters should be used on banks of 6 columns and above.
Ensure that all Heat Regenerative Dryers (DH models) are fitted with high temperature grade elements on outlet
filtration.

TYPICAL SINGLE BANK INSTALLATION
Pre-filtration
This must be positioned as close to the Desiccant Air Dryer inlet as possible. domnick hunter grades AO (3)
and AA (4) pre-filters must be fitted upstream of the inlet to prevent contamination of the desiccant beds.
In cases of extreme contamination, a domnick hunter Water Separator (5) should be incorporated into the
system.
After-filtration
A domnick hunter Grade AR (6) filter must be fitted downstream of the dryer to prevent dust carryover. Heat
