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.
