Installation
Connection fittings (accessories) must be pro-
vided at the site of installation.
Note!
Do not install the regulator directly next to an
air vaporizer. Otherwise, the regulator could
close due to the low outdoor temperature. The
closing function of the regulator does not de-
pend on whether the sensor temperature is
determined by the outdoor air or by the me-
dium.
For outdoor installation, we recommend an
adjusted set point temperature of –37 °C to-
gether with the point at which the regulator is
fully closed at –20 °C (set point range –45 to
–10 °C).
The following points generally apply:
4
The regulator can be installed in any de-
sired position
4
The direction of flow must match the ar-
row on the valve body
3
Set point adjustment
See Figs. 3 and 4
The safety temperature monitor has been ad-
justed by the manufacturer to a set point tem-
perature (limit) of T
set point
= –10 °C (set point
range from –30 to +10 °C) or –37 °C (set
point range from –45 to –10 °C).
After removing the cap (3.1) and undoing the
lock nut (3.2), the required set point
temperature (T
set point
) can be adjusted within
the set point range using the set point adjuster
(3).
