Preliminary Procedures

These instructions cover the installation of the HumidiPack

and HumidiPackPlus with the Armstrong ACV

Control Valve (models listed below). The HumidiPack and HumidiPackPlus represent complete packaged

humidification systems when used in conjunction with existing boiler steam. HumidiPack may also be

used for distribution of steam generated by electric or steam-to-steam humidifiers (steam generating). In

these instances, no strainer, control valve, or steam traps are supplied. When used with boiler steam, the

systems come with the following equipment:

HumidiPack Contents:

• HumidiPack Panel

• Armstrong Inverted Bucket Steam Trap

(to be used to drip steam supply to control valve)

• Armstrong ACV Control Valve

• Armstrong In-Line Y Strainer

(to be used prior to the control valve)

• Armstrong Float & Thermostatic Steam Trap

(for condensate drainage of HumidiPack header)

(two traps are needed for HumidiPack CF)

Step 1: Check Shipment Against Packing List.

All components are listed on the packing slip. Report any shortages immediately. If the HumidiPack or

accessories have been damaged in transit, notify us and file claim with the transportation company.

If your order covers more than one

package, segregate each complete

assembly. Equipment tagging will be the

same as shown on the packing list.

Model, Serial Number, Steam Pressure

and Orifice Size are on the metal plate on

the control valve body.

Step 2: Check Local Codes.

The Armstrong HumidiPack should be

installed in accordance with all applicable

building, plumbing, and electrical codes.

Step 3: Find HumidiPack Panel Location.

Locate all HumidiPack equipment according to the engineer’s layout or as indicated by your Armstrong

Representative. If you must locate the HumidiPack/HumidiPackPlus yourself, be sure to read and observe

the “Do’s and Don'ts” to follow.

Do’s & Don’ts of Location and Installation

HumidiPackPlus Contents:

• HumidiPackPlus Panel

• Armstrong Inverted Bucket Steam Trap

(to be used to drip steam supply to control valve)

• Armstrong ACV Control Valve

• Armstrong In-Line Y Strainer

(to be used prior to the control valve)

• Two Armstrong Float & Thermostatic Steam

Traps (one for header drainage, one for active

tube jacket drainage)

All recommendations for the application of the Armstrong HumidiPack and HumidiPackPlus are based on tests

and field experience. However, they are based on duct air velocities and temperatures that are most commonly

encountered, and the recommendations may have to be modified when velocities are very high and/or

temperatures unusually low. We also reserve the right to modify recommendations without notice if

subsequent tests or experience indicate that a change should be made. For these reasons, we urge you to

check all applications with your Armstrong Representative before installation. (Illustrations applicable to both

HumidiPack and HumidiPackPlus.) See Figures 3-1 through 3-7.
