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  Risk of burning!
 Use suitable hoses ( 6.4).
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.

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 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.
When changing the heat transfer liquid from water to a thermal transfer medium for temperatures above 100 °C,

carefully remove all water residues, including from the hoses and loads. When doing this, also open the screw plugs
(HKN 065) ( 3) of the pump outputs and inputs and blow compressed air through all the pump outputs and in-
puts. With higher temperature there is the risk of burning due to delay in boiling!
 Withdraw the mains plug before cleaning, maintenance or moving the thermostat.
Repairs in the control section must only be carried out by specialist personnel.

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 unfavourable values. Safety is not impaired.
The following action may start the thermostat unintentionally from the standby mode:

Previously activated timer mode ( 7.12),
"Start" command via interfaces ( 8).
