Auto Changeover Gas Regulator
(where fitted)
The Whale Auto
Changeover Gas
Regulator, Type 924N
has been specially
designed to supply a
caravan or motorhome
gas installation in
compliance with the
requirements of annex
D of standard EN
12864. Supply pressure
for appliances is standardised at 30 mbar for
the whole of Europe.
Note: Not suitable for use in caravans or
motorhomes when the vehicle is in transit.
WARNING: This product is designed for
use with all liquefied petroleum gases:
propane, butane and LPG.
LPG is highly flammable.
Important: In the following cases, shut off
the cock on the cylinder IMMEDIATELY and
contact your dealer or Whale Support +44
(0)845 217 2933:
• Abnormal combustion at the burner(s) of a
gas appliance (flames too high or too low)
• Smell of gas
• Outbreak of fire
A planned maintenance schedule of regular
inspection is recommended, replacing
components as necessary.
We recommend the gas regulator unit be
replaced 10 years from the date of
manufacture.
Instructions for use
The two inlets of the regulator are to be
connected by means of two high pressure
hoses complying with the specfications of
Standard EN1949.
Putting into <<service>> Figure 1.
• After having checked that the indicator
remains green in the two positions of the
knob, turn the knob so that the arrow is
facing to the right or the left. The arrow
on the knob will indicate the cylinder in
<<service>> use.
Operation of the <<reserve>> Figure 2.
• The indicator is red which means that the
cylinder in <<service>> has run out. It is
now empty and the installation is
operating on the <<reserve>> cylinder.
Replacing the empty cylinder, Figure 3.
• Turn the knob halfway. The cylinder that
was previously in <<reserve>> will
become the cylinder in <<service>> the
indicator will turn green as usual. If it
stays red, this means the system has
been operating on the <<reserve>>
cylinder for too long and that this one is
also empty. It will therefore be necessary
to change both cylinders.
CAUTION: It is strongly recommended
that only Gas Safe Register™ or STGW
approved gas fitters carry out any work
on your caravan gas installation.
