OPERATION

On a call for humidity, the Steam Humidifier provides power to the fan pack. The fan pack blower distributes the steam to the room. When the call for humidity ends and the humidifier stops producing steam, the fan pack blower will continue to operate for 2 minutes to distribute the remaining steam before de-activating. When installing the Model 800 Steam Humidifier, use the Manual Digital Humidistat included (see FIGURE 8). When installing the Model 801 Modulating Steam Humidifier, use the Model 5558 Modulating Humidistat (see FIGURE 9).

INSTALLATION INSTRUCTIONS

LOCATION

NOTICE
Fan pack must be installed over drywall for proper operation. The fan pack must be located near the Steam Humidifier to minimize the length of the steam hose. If the fan pack is mounted directly above the humidifier, 16” is required for the steam hose to make the bend. See FIGURE 2.

Six feet of steam hose is provided with the Steam Humidifier. For installations that require longer runs a combination of the steam hose and insulated copper pipe can be used. See FIGURE 3. When using more than 24” of steam hose or 36” of insulated copper pipe, install a Drip Tee and Drain Trap (Part #4028) to help control condensation and reduce gurgling. See FIGURE 4.

Due to condensation inside the hose or pipe, the output of the fan pack depends on the length of the steam hose or pipe connecting it to the Steam Humidifier. See the Steam Humidifier installation manual for maximum steam capacity (gal/day). Humidity behaves like a gas and under ideal conditions will expand to fill the space. However, air movement due to drafts or as a result of temperature stratification may cause uneven distribution of humidity within the conditioned space. Install the fan pack in a central location to ensure even distribution of humidified air. To prevent condensation on surfaces and furnishings, install the fan pack so the steam being discharged has enough room to be absorbed into the air before encountering surfaces. The following guidelines are for a 240V installation in which the unit discharges into a space with 70°F air temperature and 40% RH.

• Allow 5 feet of unobstructed space directly in front of the grille.
• Allow 2 feet on either side of the grille.
• Allow 1-1/2 feet above the grille.
• Allow 5 feet or more below the grill. See FIGURE 5.

If the room temperature is less than 70°F, allow an additional 6” to each distance for every two-degree drop in temperature. If the RH set point is higher than 45%, allow an additional foot of space between the grille and any obstruction or surface. Warmer room air temperature and RH below 35% will reduce the amount of unobstructed space required to absorb discharged steam, but the distances provided are recommended minimums.

NOTE: Condensation running through the steam hose back into the canister may cause a gurgling noise. Install the Drip Tee and Drain Trap (Part #4028) as shown in FIGURE 4 to divert condensation to the drain to eliminate gurgling noise.

MOUNT HOUSING
The fan pack installs between the studs of a standard 16” on-center internal wall. To ensure proper operation, the fan pack must be mounted level. Use the four 1-1/2” mounting screws provided to attach the housing to the wall studs. See FIGURE 6.

NOTICE

• Fan pack must be installed over drywall for proper operation.

HOSE CONNECTIONS AND STEAM MANIFOLD INSTALLATION

1. Connect the steam hose to the fan pack steam manifold and use the hose clamp (both provided with a Steam Humidifier) to secure it.
2. Install the steam manifold into the fan pack cabinet by feeding the steam hose back into the wall cavity. Secure the manifold with the two provided serrated nuts. See FIGURE 7.
3. If The am Humidifier is mounted on the wall behind the fan pack, install the provided 45° stainless steel elbow. See FIGURE 2.
4. If more than 6 feet is required, use an insulated hard pipe as shown in FIGURE 3. Refer to the Series 800 Steam Humidifier Installation & Maintenance Instructions for hose length’s effect on steam capacity.

ELECTRICAL WIRING

Disconnect all power to the Steam Humidifier before wiring the fan pack. Use standard 24-volt thermostat wire. Mount the humidistat in the area to be humidified according to installation instructions included with the control. Install the humidistat in the same room or area as the fan pack discharge, but at least ten feet away. Wire the Manual Humidistat to the Model 800 using a standard 24-volt thermostat wire. See FIGURE 8. Remove the 40VA transformer from the Steam Humidifier and replace it with the 75VA transformer supplied with the fan pack (necessary for service part 5658 only). If using the Model 65 Digital Manual Humidistat, place the provided wire harness between the control board and the 24VAC output of the transformer. Connect R and C of the humidistat to the red and white wires of the wire harness. When using the Model 801 Modulating Steam Humidifier with the Modulating Control (Part

5558), use the wiring diagram in FIGURE 9. DO NOT USE the included wire

harness.

GRILLE INSTALLATION
Use the four provided 5/8” screws to attach the fan pack grille to the fan housing and drywall. See FIGURE 10. If painting the grille is desired, see a painting professional for acceptable paint products for high temperature (212°F), high humidity environments, and polycarbonate.

START-UP PROCEDURE

Once the Steam Humidifier and fan pack are installed, turn on the main power to the humidifier and open the saddle valve. Turn on the Steam Humidifier and turn the humidistat set point up. The fan pack blower will turn on. Once the canister fills and water boils, steam will flow from the manifold and the fan will distribute it to the room. Set humidistat to desired RH.

WARNING
The front of the fan pack will be hot. Steam may not always be visible. Do not touch the front of the fan pack or place your hand in front of the steam discharge manifold. Verify that there are no leaks at the steam hose connections. The fan pack will operate on a call for humidity and the production of steam by the Steam Humidifier. When the call for humidity is deactivated, the fan pack blower will continue to operate for 2 minutes to distribute the remaining steam in the steam hose.

MAINTENANCE

After replacing the Model 80 Steam Humidifier Canister:

• Ensure the fan is operating during a call for humidification.
• Check drain, steam, and condensate hoses for kinks, blockages, leaks, or cracks. Replace if necessary.
• Ensure the steam outlet of the fan pack is not blocked.

Refer to the Series 800 Steam Humidifier Installation & Maintenance Instructions for full maintenance procedure.
