6.3.4.2 Make-up line
If you don't connect the automatic water make-up, you must close the connection of the "WC" make-up line with a R ½ " blind plug.
• Prevent a potential device fault by ensuring manual water make-up.
• Install at least one "ST" dirt trap with a mesh size ≤ 0.25 mm close upstream to the make-up solenoid valve.
– Install a short line between the "ST" dirt trap and the solenoid valve.
Note!
Use a pressure reducer in the "WC" make-up line if the idle pressure exceeds 6 bar.
Note!
If you use make-up water from the potable water system, you may need the Reflex Fillset for the "WC" make-up line, see
chapter 4.6 "Optional equipment and accessories" on page 13 .
• Reflex make-up systems such as Reflex Fillset are designed for make-up lines with a flow rate < 1 m³/h.
6.3.5 Fitting the thermal insulation
Install the optional thermal insulation (2) around the primary
tank (1) and close the insulation with the zip fastener.
Note!
For heating systems, insulate the primary tank and the "EC" expansion lines against heat loss.
– Thermal insulation is not required for either the primary tank top or the secondary tank.
Note!
On-site, install thermal insulation when condensate forms.
