INTRODUCTION NOTES.
The MON-MEVH range is designed for simultaneous ventilation for a maximum of up to four separate areas
such as bathrooms, kitchens and toilets. The range can be mounted in three different orientations for
convenient installation in roof voids with a height of 250mm or greater. An integral humidistat is provided to
automatically trigger an increased airflow in order to quickly remove any buildup of humid air caused by
showers, cooking etc. The MON-MEVH employs highly efficient backward curved centrifugal motor impeller
sets. All models are designed for continuous 24-hour use and should not be used in conjunction with a delay
timer.
HUMIDISTAT.
The humidity set point is adjustable between 60% and 90% RH with a mid-point potentiometer setting of 75%
RH. Once a humidity level is dedicated above the set point value, the MON-MEVH will initiate a fixed airflow
boost cycle depending on the initial speed setting of unit when the humidity rise was detected.
SITING
The MON-MEVH may be mounted in three orientations.
a).
Base mounted Installation
with ducting radiating out horizontally. The Condensate Drain is on the
opposite side to the exhaust spigot at the base of the unit.

Installation
with the exhaust spigot at top. The Condensate Drain is opposite to the
exhaust spigot at the base of the unit. Additional drainage may be required from the duct connected to the
bottom spigot.
