Note 1: Route all drain lines through a pipe chase. Seal the pipe chase to isolate the unit from the pres-
sure inside the building.
Note 2: In cold climates all drain lines must be properly trace heated and insulated to prevent freezing.
Note 3:
The air gap funnel should be located inside the building, as shown, and connected to a dedicated
building drain (recommended) with a drainage capacity of at least 2.3 gpm (8.7 L/min) for an EL-OC unit
and 6.7 gpm (30 L/min) for a RS-OC unit – per steam cylinder. The drain line exiting the funnel should be
minimum 7/8 in (22 mm) in diameter for an EL-OC unit, and minimum 1-3/4 in (45 mm) for a RS-OC unit.
The drain lines into the funnel must not touch the sides or bottom of the funnel. In large units, separate
air gap funnels must be used for drain lines from each cylinder.
Note 4: In cold climates the water supply line should be protected with a freeze protection system utilizing
either a normally-open and a normally-closed valve, or a 3-way valve. Refer to
"External Freeze Protection
System" on page 35
for details.
Note 5: The water supply line should have a 1/2 in NPT female end for connection to the unit. It must be
routed through a pipe chase. In cold climates it must be properly trace heated and insulated to prevent
freezing.
Note 6: The supplied mounting bars must be installed on a reasonably flat vertical mounting surface on
the air handling unit, that is stable and suitably reinforced (strength equivalent to 2×4 stud or 1-5/8 in ×
1-5/8 in ×12 gauge Unistrut® channel). Make sure that the mounting surface is capable of supporting
the entire weight of the unit when it is in operation – refer to
Table 9 on page 57
.
When choosing this mounting arrangement, locate the humidifier as close as possible to the
steam distributor to minimize condensate losses and backpressure in the line. Do not install the
Nortec EL/RS Outdoor humidifier in an outdoor environment where the unit is exposed to severe weather
or where the temperature drops below -40 °F (-40 °C).
IMPORTANT! In units operating in cold climates, the area around the unit must kept clear of snow
and ice accumulation to permit opening and closing of the front and side doors.
Refer to
"Site Requirements"
below, and
"Exterior Wall Mounting" on page 28
for mounting details. Make sure
the required ground clearance is maintained – refer to
Figure 8 on page 22
. Observe all local and national
installation codes. Nortec is not responsible for any installation code violations.
The water supply and all drain lines must be properly trace heated and insulated to prevent freezing.
IMPORTANT! The warranty does not cover damage to the humidifier resulting from freezing.
