Device Installation Room; Electrical Installation - Rotex GCU compact 315 Installation And Maintenance Instructions Manual

1 x General safety precautions

1.2.3 Device installation room

WARNING!
The plastic wall of the storage tank of the
GCU compact can melt under the effects of ex-
ternal heat (>80 °C) and, in the extreme case,
can catch fire.
● Only install the GCU compact at a minimum
distance of 1 m to other heat sources
(> 80 °C) (e.g. electrical heater, gas heater,
chimney) and combustible materials.
CAUTION!
● Only install the GCU compact if sufficient
load-carrying capacity of the ground of
2
1050 kg/m plus safety margin is ensured.
The ground must be flat, horizontal and
level.
● Outdoor installation is not permissible.
● Installation in an explosion-risk environment
is not permissible.
● The electronic control system must not be
exposed to whether effects like rain and
snow under any circumstances.
● The storage tank may not be exposed to
continuous direct sunlight, as the UV
radiation and the effects of the weather will
damage the plastic.
● The GCU compact must be installed
protected from frost.
● Only operate the ROTEX GCU compact when
a sufficient combustion air supply is ensured.
If you operate the ROTEX GCU compact as
ambient air-independent with a concentric
air/flue gas system (LAS) dimensioned
according to ROTEX standard, this is
automatically ensured and there are no
further conditions for the device installation
room. Only this method of operation is permis-
sible for installation in residential rooms.
● Make sure that there is an outside air opening
2
of at least 150 cm
or partial ambient-air independent operation.
● Do not operate the ROTEX GCU compact in
ambient-air dependent operation in rooms
with aggressive vapours (e.g. hair spray,
for ambient-air dependent
perchloroethylene, carbon tetrachloride),
strong dust formation (e.g. workshop) or high
humidity (e.g. laundry).
● Avoid operating conditions that can cause
heavy soiling of the burner. Do not operate the
device if temporary heavy dust deposits occur
in the area of the air extraction system.
● Always ensure the minimum distances to
walls and other objects (see chap. 4.1).
CAUTION!
● If a DrainBack solar heating system is
connected: Install the GCU compact far
enough under the solar panels to allow
complete emptying of the solar heating
system. (Follow instructions of the
DrainBack solar thermal system manual).
An insufficient height difference may lead to
destruction of the DrainBack solar thermal
system.
● The GCU compact must not be operated in
rooms with ambient temperatures above
40 °C.

1.2.4 Electrical installation

● Electrical installations may only be carried out
by electrical technicians and in compliance
with valid electrical guidelines as well as the
specifications of the responsible energy
supply company.
● Compare the mains voltage (230 V, 50 Hz)
indicated on the nameplate with the supply
voltage before connecting to the mains.
● Before beginning work on live parts,
disconnect them from the power supply
(switch off main switch, remove fuse) and
secure against unintentional restart.
● Equipment covers and service panels must be
replaced as soon as the work is completed.
