Vectaire ELPREX 16 Installation And Operating Instructions

IMPORTANT
If the fan is installed in a ceiling with a vertical duct passing through an unheated space, a condensation trap MUST be fitted.
Any ducting in an unheated space should also be insulated according to the latest Building Regulations recommendations in the
Domestic Ventilation Compliance Guide. Failure to do this could result in condensation affecting the operation of the fan and cause
damage to the ceiling.
If the fan is to be ceiling mounted, the pull-cord switch should be put in the "off" position and the cord removed.
A remote switch will be necessary for changing the fan speed. See wiring diagrams,below.
TRIMMER ADJUSTMENT
To adjust the humidistat and timer trimmers, remove the front cover and circuit board
cover of the fan to access the trimmers. The humidistat (HY) can be adjusted betwe-
en 40% and 90% relative humidity. Turn clockwise to decrease sensitivity and set
at a higher level of relative humidity. The timer (TM) is adjustable between 0 and 30
minutes. Turn the trimmer clockwise to increase the overrun time, or anti-clockwise to
decrease it. (see image below)
JUMPER SWITCH
These fans are designed to run continuously at a low speed with a choice of three boost speeds (boost speed to be set at instal-
lation). The configurations for the optional boost speed are as follows:
30 l/s 45 l/s 60 l/s
