and
siting
−
Site the unit on a flat surface
−
The unit must not be put into operation if its
temperature during storage or transport has dropped
below the dew point.
Wait for about one hour.
−
The unit may NEVER be overturned nor put upside
down!
−
Do not cover the ventilation openings at the back of
the control head and on all sides of the lower section
of the unit.
−
Leave at least 40 cm of free space on all sides.
−
For operation as bath thermostat, set the bypass valve
to internal (without external loads) (
Ì
−
Plug the (high resistance) connector into the
corresponding socket 51H on the back of the control
head, the Bus-cable into the plug 70S and secure
both.
−
Only RP 890 and RP 1290: In case of disturbing
dewing, connect the heating of the bath bridge. Plug
the supplied T-piece adaptor cable for the LAUDA
device bus into the 70S socket and secure it. Connect
it with the connection cable of the bath bridge heating.
−
Plug the bus connector of the Command console also
into the 70S socket or into the T-piece and secure it.
−
Further T-adaptors are available as accessories
EKS 073.
−
Avoid condensation of air humidity: Connect nitrogen
or dry air with a low volume flow for superposition to
the nipples of the bath covers of the minimum
temperature thermostats RP 890 and RP 1290.
Operation with external loads
(Circulating thermostat) continue at
Ì
−
Check whether the pump connectors at the side and back are fitted with sealing
caps (
Ì
Section 3) or that hoses are fitted for external loads.
−
With bath temperatures over 70°C the supplied self-adhesive label
should be applied on the bath at an easily visible point.
−
Do not carry out technical changes on the device!
In particular, it is not allowed to bore into the edges of the bath!
−
The unit can be safely operated up to an ambient temperature of 40°C.
−
An increased ambient temperature reduces the cooling capacity.
