It is often desirable, especially in pool rooms and
finished areas, to install the HI-E Dry 95 hidden in
an adjacent equipment room or unfinished area. Air is
transferred between the humid room and the unit via
ducting. The factory mounted humidity control on the HI-E
Dry 95 cabinet may not sense the humidity in the humid
room accurately enough with this installation method. If
so, a remote 20 Vac humidity control can be mounted
in the humid room and wired to the HI-E Dry 95. Local
electrical codes must be fol¬lowed when rewiring the
control.
2.1D In Remote Area, Duct Outlet Only
A simpler remote installation method than the one above
uses ducting only between the HI-E Dry 95 discharge
and the humid room. The HI-E Dry 95 inlet draws air
from the room in which it's located. This works well
if there is an adequate airflow path between the two
rooms; e.g., high door undercut, louvered door or wall
grill. This eliminates the need to remote mount the
humidity control. There are several disadvantages to
using this method. First, humid air is drawn into the room
where the HI-E Dry 95 is located. Second, to accurately
sense humidity, the blower in the HI-E Dry 95 may need
to run continuously to draw air from the humid room into
the HI-E Dry 95 room. Third, a slight negative pressure
is created in the room with the HI-E Dry 95, which could
back draft, open combustion devices located there. If
such devices are present, call the factory for spe¬cific
instructions before using this installation method or
consider the option below.
2.1E In Remote Area, Duct Inlet Only
When the HI-E Dry 95 is located in a room separate
from the main area to be dehumidified, it may be
desirable to dehumidify and/or slightly pressurize that
room. Pressurization assures that open combustion
devices do not back draft, as would be the case if
the room were sufficiently depressurized. This can be
accomplished by installing a duct from the humid room
to the HI-E Dry 95 inlet and by allowing the HI-E Dry 95
to discharge the dehumidified air into the room in which
it's located. An adequate airflow path must exist between
the two rooms for this method to work well. A humidity
control for the HI-E Dry 95 may need to be remote
mounted and wired to the humid area to accurately
maintain the desired humidity. Local electrical codes
must be followed when rewiring the control.
2.2 Electrical Requirements
The HI-E Dry 95 can be plugged into a grounded 5
Amp circuit. At 80°F, 60% RH, it draws .4 Amps. Due
to the high percentage of a 5 Amp circuit's capacity that
the unit uses, the circuit should be dedicated to running
it only. Amp draw decreases at lower loads and increases
at higher loads. At extremely high loads, a 20 Amp circuit
may be required.

If an extension cord is required, it must have a minimum
of 2 gauge conductors if 25 feet long or less and 0
gauge conductors if greater than 25 feet long.
2.3 Condensate Removal
The HI-E Dry 95 is equipped with an internal
condensate pump to remove the water that is condensed
during dehumidification. This allows the condensate to be
pumped 20' with the attached hose. If the condensate
must be pumped more than 20 feet above the unit, a
second pump must be added to relay the condensate.
The condensate pump is mounted inside the HI-E Dry
95 as a permanent, integral part of the unit. It includes
a safety switch feature that prevents flooding by turning
off the HI-E DRY 95 if the pump fails.
2.4 Ducting
2.4A Optional Ducting kit
Two twelve-inch collars are available as a kit from the
factory that will allow ducting to be attached to the inlet
and outlet of the HI-E Dry 95. Attach the inlet collar to
the top of the unit by cutting the eight tabs that support
the 2" round opening in the top. The 2" collar with
three tabs can be attached via the holes provided in the
front of the unit, and the other 2" collar can be affixed
to the top opening.
2.4B Ducting for Dehumidification
Ducting the HI-E Dry 95 as mentioned in sections 2.B-
2.E requires consideration of the following points:
Duct Sizing: For total duct lengths up to 25', use a
minimum 0" diameter round or equivalent rectangular.
For longer lengths, use a minimum 2" diameter or
equivalent. Grills or diffusers on the duct ends must not
excessively restrict airflow.
Isolated Areas: Effective dehumidification may require
that ducting be branched to isolated, stagnant areas.
Use 8" diameter branch ducting to each of two or three
areas; use 6" to each of four or five areas; use 4" to
each of six or more areas.
2.4C Ducting for Fresh Air
Fresh air can be brought into the structure continuously
by connecting a duct from outside to the HI-E Dry 95
inlet and by turning on the fan switch. Advantages of this
form of ventilation include:
. Outside air is filtered before entering the building.
2. Outside air will be dehumidified before entering if the
HI-E Dry 95 is running.
3. Drawing air from outside and blowing inside aids
in pressurizing the structure. This helps prevent
unfiltered and undehumidified air from entering
elsewhere. It also reduces the potential for
carcinogenic radon gas to enter.
