Installation
16
Unit location:
Installation must be in a
dry, frost- and draught-protected
room and at an accessible height.
Insulation of complete pipe system is indispensible,
-> minimum thickness 30 mm, heat conductivity
.
Water line has to be insulated against condensation of water and heat loss.
Water connection:
Water supply line 1”, water outlet line 1”, circuit piping: min. ¾”, max. 1”,
Water pressure has to be between min. 1 bar (14 psi) - max. 4 bar (58 psi)!
If water pressure is lower than recommended, install a pressure intensifier.
If water pressure is higher than recommended, install a pressure reducer valve.
Circuit length
Length of the insulated water tube system incl. all return pipes should
not exceed 250 m (820 feet)
Circulation pump
Circulation pump must run on
positon 3
.
Circulation pump has to be bled (see page 23).
The height difference between entry and return pipeline
should not exceed 7 meters.
Functioning capability of circulation pump has to be constantly checked!
Application field:
SUEVIA Heating Unit Mod. 311
is exclusively designed to keep water pipes frost-free in stables
for animals.
It can only be used for warming up water, other liquids are not allowed!
Pipe insulation:
