e Mini NEB is a centrifugal humidier; meaning it atomizes
water by using centrifugal force. It is engineered to be simple,
safe, and eective. For the humidier to function properly, it
should have a permanent water connection and be fed either
tap or fully demineralized water. e most common method
of obtaining demineralized water is by reverse osmosis ltration
(RO). Please, follow these installation and maintenance in-
structions carefully in order to assure ecient and safe opera-
tion of your humidier.
2.1 General safety rules
»Before installing the unit OR performing any maintenance
or inspection of the unit, be sure it is disconnected from the
power supply.
»Read all instructions before operating humidier.
»Keep humidier free from obstructions to allow unit to
function properly.
»e humidier must be connected to an electrical supply
that complies with local regulations. It is strongly recom-
mended to plug the humidier into a properly grounded
receptacle. Ground fault receptacles are strongly recom-
mended and may be required by local code.
»is humidier has been designed for air/water humidi-
cation only. Any other use for the product is prohibited
and will void the product warranty. Do not use the unit for
humidication of any chemicals, pesticides, or insecticides.
Any use dierent than that described here is improper and
potentially dangerous and harmful.
»Humidistat is designed only for indoor use.
»Monitor humidistat and fogger for initial cycles to ensure
correct operation.
»Keep these instructions in a safe place, near the humidier
for reference.

3.3.2 Cabling
Pic.5 - Cabling
If installing your own power cord, use only a three prong
grounded cord with minimum 16 gauge wire.
Referring to Pic. 6:
»To install a power cord, rst remove the cover from the elec-
trical connection box on the rear of the humidier by un-
screwing the four screws V. A Phillips head screwdriver is
needed.
»Unscrew the grey cap at the end of the power cord holder
P. Slide the cap rst down the end of the power cord then
insert power cord through the hole of the power cord holder.
Do not fully tighten the cap until proper slack and distances
inside the power box have been set.
»Carefully remove the electronic board Mfrom the box by
gently pulling it directly backwards. It should slide out from
the slots G.
»Connect all three wires-phase, neutral, ground- to the rst
three terminals on the circuit board. Match white to white,
black to black, and green to green.
»Put the electronic board back into electrical connection box
by sliding it back carefully into the slots G.
»Close the electrical connection box and reinsert the four
screws into their proper holes. Verify enough slack is in the
box and then tighten down the cap on the power cord holder
to secure the cord in place and also prevent moisture from
entering the electrical connection box.
3.4 Hydraulic connections
Pic.6 - Hydraulic connections
e installation of the humidier requires 2 water connections—
one to feed the humidier (water supply hose) and one for drain-
ing (drain hose). Both are included with your humidier.
3.4.1 Water Supply Hose
e water supply hose has 3/4” diameter ttings at both ends.
Connect the end that is “L” shaped to the male tting at the rear
of the humidier. Tighten rmly and plumber’s tape can be used
to reduce any leaking. e other end should be connected to
your water supply, which should also have a 3/4” male tting. It
is possible to use reducers to take the hose diameter down from
3/4” to 1/4” in order to use 1/4” tubing instead of 3/4”.
IMPORTANT! Water Quality. e use of water that has
gone through the process of reverse osmosis (RO) water
ltration is HIGHLY recommended to reduce calcium car-
bonate sediment occurring in the area being humidied,
as well as helping keeping the humidier clean and free
from sediment blockages.
3.4.2 Drain Hose
e drain hose should be installed by sliding it on to the water
discharge port of the humidier—which is located below the
water inlet male tting. A longer hose can be used; just make
sure it has an internal diameter of 3/8”.
IMPORTANT! –Drain Hose Placement. e drain hose
must be hung down from the humidier’s installed loca-
tion at a very minimum angle of 10 in order to assure
the water will drain correctly. e hose should hang as
straight down as possible. Make certain there are no
kinks, bottlenecks, or elbows in the hose to prevent water
from draining out of the hose. In addition, the end of the
drain hose should be kept free from blockage and 1) NOT
placed below the water’s surface in the drain and 2) NOT
placed in a closed container that will have sucient pres-
sure to keep the water from draining out of the hose (See
8M869-4_GB_letter
mini NEB
ENGLISH
Pic. 8).
Pic.7 - Drain hose placement
WARNING! Any failure in the drainage can cause water
dripping from the humidier.
3.5 Installation
e Cuoghi Mini NEB humidier can be installed in one of two
ways: Mounting on the side of a wall or Hanging from a ceiling.
Hardware for both is provided with your humidier
3.5.1 Wall installation
Pic.8 - Wall mounting bracket and holes on the wall
Use the supplied metal bracket with screws to install the humidi-
er to a wall (see Pic. 9). Use the bracket as a template in order
to determine screw placement.
»Drill three 1/4” diameter holes as in Pic. 9.
»Insert screw anchors into holes. Fasten bracket to the wall
and conrm mounting is solid.
»Loosely attach bracket to rear of Cuoghi Mini NEB using
the four included screws.
»Once installation is conrmed to be solid and secure, tighten
four screws attaching bracket to rear of humidier.
IMPORTANT:
Observe minimal distances in Par 3.2 when wall
mounting the Cuoghi Mini NEB.
Make sure bracket is completely horizontal before
drilling holes.
Be certain the wall is able to sustain the weight of the
humidier (10.9 lbs). If drilling through drywall, it is
highly recommended to screw into the studs behind the
wall or to use wall anchors
3.5.2 Ceiling installation
Use the three supplied hooks along with chain (not included) to
hang the Cuoghi Mini NEB humidier from the ceiling.
Pic.9 - Hooks
»Observe minimal distances in Par 3.2 when hanging the
Cuoghi Mini NEB.
»Predetermine where the three support chains will be at-
tached to the ceiling in order to keep the chains as vertical
as possible.
»Choose a chain material that can both sustain the weight
of the humidier as well as to not be adversely aected by
humidity.
»Attach the three supplied hooks to the bottom of the Cuoghi
Mini NEB.

4.1 Checks
»Check both water connections (water supply and water
drain). Will water be adequately supplied? Can the waste
water drain quickly and easily?
»Check electrical connections. Is the unit plugged in? Is a
humidistat or similar control wired to the humidistat con-
nections (H-H) on the electronic control board?
»Is the electrical connection area completely water free and is
the back cover plate securely screwed down?
»Is the air lter installed at the bottom of the unit?
»Is the water supply (tap) turned on, supplying water to the
unit?
»Is the fogging head at the top of the unit positioned outward
and away from a wall or piece of equipment?
»Is the unit installed observing the minimal distances in
Par.3.2.
4.2 Start up
»Power the unit on and, if equipped with a humidistat, turn
the humidistat DOWN to a level that will trigger the hu-
midistat to CLOSE the main switch at the H-H terminals.
»e unit should start immediately, and after a few seconds,
it will start atomizing water.
»Check both water connections both for leaks and to make
sure the unit will discharge water properly through the drain
tube.
4.3 Turn o
»To turn the unit o, either disconnect the power supply or,
if equipped with a humidistat, turn the humidistat UP to
a level that will trigger the humidistat to OPEN the main
switch at the H-H terminals.
»e humidier will slow down and the water inside the unit
will fall back down to the water basin and trigger the siphon,
where it will be discharged through the drain hose.
IMPORTANT! After shutting down the humidier, wait at
least 30 seconds to allow the waste water to be completely
discharged, otherwise the siphon may not completely close
and water will be continuously discharged through the
drain hose when the unit is then powered back on.
5.1 Introduction
e Mini NEB is designed to perform eciently and to provide
problem free performance for a long time. However, regular
maintenance is needed in order to keep the unit running e-
ciently, cleanly, and safely.
IMPORTANT: How frequently maintenance needs to be
performed is determined by two factors: 1) e environ-
ment in which the humidier operates and 2) the quality
of the water supply. However, it is recommended that the
unit be examined for possible maintenance at least every
30 days!.
BEFORE PERFORMING ANY MAINTENANCE TO THE
HUMIDIFIER MAKE SURE THAT:
THE UNIT IS COMPLETELY POWERED OFF AND IS
UNPLUGGED FROM ANY POWER SUPPLY.
THE MACHINE HAS COMPLETELY STOPPED.
THE WATER SUPPLY HAS BEEN COMPLETELY
TURNED OFF
5.2 Inspection and cleaning of the water feed
solenoid valve
e water feed solenoid valve is tted with an inlet lter that
must be periodically checked and cleaned.
To access the lter, unscrew remove the water supply hose: the
lter Cis located inside the threaded bush Sof the solenoid
valve.

ENGLISH
Pic.11 - Solenoid valve
If cleaning becomes too frequent, it is advisable to install a car-
tridge lter on the water supply line (see: paragraph 3.4 - Hy-
draulic connections)
WARNING: do NOT run the humidier without the water
lter C.
5.3 Air lter cleaning
Pic.12 - Air lter disassemble
e air lter will need to be cleaned periodically as dirt and dust
will accumulate in the lter and reduce the incoming air ow
which will lower the overall eciency of the humidier. How
often the air lter needs to be cleaned depends on the air quality
and the environment in which the humidier operates.
To clean the air lter:
»Disassemble the lter assembly by unscrewing the two screws
“V” that keep the plastic screen “R” in place.
»Remove plastic assembly and mesh air lter.
»Clean the air lter media rst by vacuuming, then by rinsing
upside down with water and a household detergent.
»Let the air lter media dry naturally; do not ring or squeeze
it. Reassemble all of the pieces; carefully checking that the
air lter media is correctly positioned in the plastic assembly
and then re-tighten down with screws.
»Air lter media must be completely dry before reinstallation
and starting the humidier.
IMPORTANT! Never run the humidier without the air
lter assembly.
5.4 Basic cleaning of the drain
Pic.13 - Parts to be cleaned
»Remove the grid and the air lter.
»Remove and clean the plastic elbows E1 and E2, the pipes
P1 and P2.
