Aprilaire 360 User manual

1. Disconnect electrical power before doing any 120 VAG wiring. Failure to do so could
result in serious injury from electrical shock.
2. The humidifier will be hooked up to hotwater. Hot water temperatures in excess of 125°F
may cause burns.
3. If the humidifier is installed in a room that has any gas or oil fired equipment or fumes,
the humidifier must have supply and return ductwork.
4. Avoid hazards and obstructions such as electrical wires and plumbing when cutting into
walls for placement of supply and return grills.
5. To avoid head injuries, mount humidifier as high as possible out of high traffic areas.
1. Check all state and local codes regarding electrical wiring and the air distribution
system.
2. The humidifier and duct system must be installed on an inside wall with air temperature
at 65°F or above. If not, condensation damage may result.
3. Do not use water in excess of 140°F at humidifier or damage to the humidifier may result.
4. Use 1/2" ID or large plastic hose to carry flushing water from humidifier to drain.
5. Do not use solvent type adhesives when connecting the plastic drain hose to the plastic
drain fitting. Damage to the drain fitting will result. Be sure the drain line has an adequate
slope to the drain.
Locate the humidifier near a drain and a hot water supply. Allow adequate space for
humidifier maintenance and service.
(See Figures 1, 2, 3 and 4)
Use the plastic inlet wall frame as a template to determine the exact position of the
humidifier.
1. Cut a 14" wide x 13" high opening through the wall centered between the vertical studs,
as shown in Figure 1.
2. Secure the inlet wall frame with narrow flange into the wall opening and the wider flange
with the mounting holes on the room side to the wall with the 1-1/2" long screws
provided. This must be square and level and part of the inlet wall frame should rest on
top of the sheet rock or paneling for additional support.
3. Secure the outlet grille frame with the screws provided. It must line up with the inlet wall
frame so the housing will fit squarely into the wall.
4. Slide the housing into the inlet wall frame so the unit butts up tightly against the outlet
grille frame. Check for level and squareness. To secure housing to inlet mount frame, drill
at least two 1/8" holes as shown in Figure 2 and secure with screws provided.
DO NOT install the Mode! No. 360 in a confined room that has gas or oil-fired vented
equipment offumes.
Where doors are normally closed, the door should have a 1/2" minimum undercut or have
a grille installed for proper air circulation. The unit will move approximately
150 cfm of air through the wall.
Maximum water temperature to the unit should be 140°F. It will be necessary to blend hot
and cold water whenever water temperature exceeds 140°F. (rankless domestic water
systems may have water temperatures in excess of 140°F.)Heatfor evaporation is obtained
from service hot water.
Some water heaters do not recover as rapidly as others; therefore, be sure that the water
heater has sufficient capacity ano recovery rate to supply a minimum of 6 gallons per hour
of 140°F hot water to the humidifier.
Tap off the hot water line at the water heater using the saddle valve provided and 1/4"
copper tubing (notfurnished). The 1/4"copper tubing is connected to the inlet fitting under
the humidifier. Double wrench when making the connection.
