10 Safety information YAUE0007 / 10/2/2018
1.2 General safety information
A heating and cooling thermostat heats or cools and circulates heat transfer liquids according to
specified parameters. This involves hazards due to high or low temperatures, fire and general hazards
due to the application of electrical energy.
The user is largely protected by the application of relevant standards.
Further hazard sources may arise due to the type of tempering medium, e.g. by exceeding or
undercutting certain temperature thresholds or by the breakage of the container and reaction with the
heat transfer liquid.
It is not possible to consider all eventualities. They remain largely subject to the judgment and
responsibility of the operator.
The equipment must only be used as prescribed and as described in these operating instructions. This
includes operation by instructed specialist personnel.
The equipment is not rated for use under medical conditions according to DIN EN 60601-1 or
IEC 601-1.

Instructions for Class A digital devices
“This equipment has been tested and found to comply with the limits for Class A digital device, pursuant
to Part 15 of the FCC (Federal Communication Commission) Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency energy and,
if not installed and used in accordance with the instruction manual, may cause harmful interference to
radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.”
“This device complies with Part 15 of the FCC (Federal Communication Commission) Rules. Operation
is subject to the following two conditions: (1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may cause undesired
operation.”
Only for Canada:
“This Class A digital apparatus complies with Canadian ICES-003” (ICES = Interference Causing
Equipment Standards).
« Cet appareil numérique de la Classe A est conforme à la norme NMB-003 du Canada ».
1.3 Other safety information
Only connect equipment to PE grounded mains sockets.
At higher operating temperatures, parts of the bath cover can reach surface temperatures exceeding
70 °C. Be careful when touching it! Danger of burning!
Use suitable hoses (6.3).
Secure hose against slippage with the aid of hose clips. Avoid kinks in the hoses.
Check hoses from time to time for any possible material fatigue.

Proline Kryomats
YAUE0007/ 10/2/2018 Safety information 11
Thermal medium hoses and other hot parts must not come into contact with the mains cable.
With the use of thermostats as circulating thermostats hot or cold liquid can be emitted when the hose
breaks, presenting a hazard to persons and material.
If no external load is connected, the pump outflow must be closed (use screw plugs) and the bypass
valve must be set to "internal" (4.3).
Take into account the thermal expansion of the heat transfer oils with increasing bath temperature.
Irritant vapors may develop, depending on the heat transfer liquid and operating mode used. Always
ensure that the vapors are adequately extracted. Use the bath cover.
By changing the heat transfer liquid from aqueous heat transfer liquid to a thermal transfer liquid for
temperatures above 100°C, carefully remove all water residues, including from the hoses and loads.
When doing this, also open the blanking caps of the pump outputs and inputs and blow
compressed air through all the pump outputs and inputs. Danger of scald due to delay in
boiling!
Withdraw the mains plug before cleaning, maintenance or moving the thermostat.
Specialist personnel must only carry out repairs in the control section.
The following action may start the thermostat unintentionally from the standby mode: Previously
activated timer mode (7.10), "Start" command via interfaces (8).
Figures of temperature constancy and display accuracy apply under normal conditions according to
DIN 12876. Electromagnetic high frequency fields may in special cases lead to unfavorable values.
Safety is not impaired.
Only water-cooled devices:
The return hose of the water-cooling must be securely fixed on the outlet port in order to prevent the
hose sliding off uncontrollably, also during pressure surges.
The return hose of the water-cooling must be fixed on the outlet port that hot cooling water cannot
splash out.
It is essential to prevent kinking or squashing of the return hose for the water cooling. Excessive
pressure can cause the cooling water hoses to tear and hot water to escape.
To prevent damages by a leakage of the cooling water system its recommended to use a leak-water
detector with shut-off valve (Aqua Stop).
1.4 EU conformity
The device complies with the basic health and safety requirements outline in
the Directives listed below.
Machinery Directive 2006/42/EC
EMC Directive 2014/30/EU

Pollution degree: 2.
4.2 Types of unit
The type designation of the Proline Kryomats comprises the prefix R (to designate the refrigeration
machine), a P for Proline, the bath volume in liters and the lowest bath temperature (guide figure
without arithmetic sign).
The designation is supplemented with a "C" which indicates the presence of the Command remote
control.
For units with water-cooling, the type designation is supplemented with a "W".
Examples: RP 4090 CW is a low-temperature thermostat with 40-liter bath and -90 °C lowest
temperature. The unit has a Command remote control and is water-cooled.
4.3 Varioflex pump
All units are fitted with a Varioflex pump with a 4-stage variable drive (pump level 5 to 8). The pump
power can therefore be optimally matched to the relevant task. In order to achieve optimum
temperature homogeneity in the heat transfer liquid in the bath, it is recommended to select the pump
level in dependence of the viscosity of the heat transfer liquid; therefore at higher viscosity to increase
the pump level.
Be cautious at higher bath levels to avoid liquid to slop over the bath edge.
The user cannot set the pump levels 1 to 4, because there is no sufficient temperature homogeneity in
the bath vessel. With pump level 0 the unit goes into the standby mode. It should be noted that the
heat input of the pump into the bath increases with increasing pump level.
With the Varioflex pump, open containers can be operated at a constant level when a level controller
(accessory LCZ 0660) is used.
At the right-hand side and at the back of the unit outflow and inflow nozzles of the pump are fitted for
external loads. This means that up to two external loads can be directly connected without a
distributor. Pump connections, which are not required, must be closed off with the supplied caps and
union nuts.
A bypass valve can subdivide the total volume flow variably between the bath (internally) and the
connected load (externally). Attention: the external application must not block the volume flow. If no
load is connected to the pump connector, the bypass valve must be set to the “internal”position for
the best bath circulation. All pump connections must be closed off with the supplied caps and union
nuts.
