-
No short-circuit / air intake and outlet next to each other
-
No thermal and sound bridges Foamed insulation in cutout, no direct
connection
with
wall
-
Noise damper: Noise damper must be installed for AEROTOP T20 and later.
With Outdoor HP Installation
-
HP must be placed on base/pedestal
-
Air flow must be unobstructed
-
Ensure min. distances house / heat pump
-
Condensate drain into seepage pit
Casing must project 1 cm into the enclosure to prevent condensate from flowing
along line and into the building
-
Noise damper: Noise damper must be installed for AEROTOP T20 and later.
-
Check inspection glass in cooling circuit (green range / starts at approx. 40° flow, no
bubbles
visible)
-
Check noise, sound of unit (compressor turns over without excessive noise)
-
Check solid-borne noise transmission (flexible connection, sound-dampening pipe
suspension, vibration transfer on floor)
-
Delta T heater side must be between following values/ above pump speed value:
At low outside temp.(–5°C):
6-8K
At med. outside temp. (+12°C):
9-12K
At high outside temp. (+20°C):
10-13K
At very high outside temp. (+30°C):
12-15K
Different source temperatures results in variable temperature spreads!
Safety Tests
-
Test safety cutout: This involves shutting off the heater side flow.
(Error 222 high pressure shutoff)
-
Test defrost until end of defrost (manual defrost press "reset key" for 5 sec)
