PLEASE NOTE (only for 004U8044):
For systems with DHW recirculation the bypass thermostat
must alway be installed before the heat meter.
On substations, that are supplied with bypass thermo-
stat mounted after the heat meter (Akva Lux II TDP-F, Type
004U8044), the bypass thermostat must therefore be relocated
before the substation is prepared for recirculation, - i.e. the by-
pass thermostat must be mounted before the heat meter.
Please follow the below instructions:
1.
Start by shutting o all connections to the substation.
2.
First follow the instructions for Fig. 1, 2, 3 and 4 on page 23.
3.
Then demount 3/4” plug in T-piece (pos. A), as illustrated in g. 1.
4.
Remove the existing capillary tube from pos. C to D. See g. 2.
5.
Demount bypass thermostat incl. 3/4” reducer bushing from pos. B.
Unscrew 3/4” reducer bushing from bypass thermostat (the 3/4”
reducer bushing is not to be reused). See g. 3.
6.
Mount bypass thermostat in pos A, as illustrated in g. 4.
7.
Plug the hole in pos. B with 3/4” plug (from pos A) and gasket, as
illustrated in g. 5.
8.
Plug the hole in pos. D with a steel ball and 6 mm union nut.
