Note:
Do not exceed the maximum operating temperature.
(1) Outside temperature: For transport and storage of the TD units the minimum
and maximum allowable temperatures are -20°C and +50°C. It is recommended
that these temperatures are used for transport by container.
(2) Refer to the minimum water flow rate for each machine (see chapter 6.2).

(1) Maximum flow rate at an available pressure of 20 kPa minimum
(2) Maximum flow rate at a water temperature difference of 3K in the plate
heat exchanger
NOTE: For a domestic hot water application (leaving water
temperature = 65°C), the water temperature difference must
be 8 K minimum for operation at 100% capacity.
6.3 -
Minimum water flow rate
Operation below the minimum flow rate of the machine can cause
a risk of freezing and excessive fouling of the condenser.

6.4 - Maximum plate heat exchanger water
flow rate
This is limited by the permitted plate heat exchanger pressure
drop. Also, a minimum condenser ∆T of 3 K must be guaranteed,
which corresponds to a water flow rate of 0.09 l/s per kW.
