Schematic diagram, filling
The filling equipment is represented by the parts drawn with dashed lines.
Note: It must be possible to bleed the collector pipes wherever air pockets
can form. Always check the filter (99) when filling and bleeding the brine
system.
!
The mixing vessel
and pump should be
a good size.
Valves
To make it easier to service the cooling unit, shut-off valves must be fitted to
both the incoming and outgoing connections. Fit bifurcated valves so that
you can fill and bleed the collector loop later on.
Bleeding
The collector loop should not contain any air. Even very small amounts
of residual air can jeopardise the heat pump's operation. See Filling and
bleeding below.
Insulation against condensation
All pipes in the brine system must be insulated against condensation,
otherwise heavy ice and condensation may form.
