Fixing ASHP Anti Vibration Feet

[BadgerBadger]

Hi hive mind!  I need a sanity check please!  Just installing our Ecodan heat pump which I got with big rubber block anti vibration feet.  The heat pump bolts to the metal channels in the feet, but there's no obvious way to secure the feet to the ground/concrete slab.  Is it right that it just sits there on the feet? 

 

I have solid/flat area so it should be stable, I was just slightly surprised.

Mine arent bolted down.  Unit weighs 125kg so isnt going anywhere in a hurry!

Mine just sat on the feet, but on gravel, we have 70+mph wind nothing moved.

Our ASHP is on the flat roof completely exposed - over 100 mile an hour winds - 600mm long rubber feet - no movement so far after 4 years.

They bolted down mine, rawlbolts into a concrete yard area. I was happy to see this as the twin-fan Vaillants are quite tall and machinery can creep about with vibration - my bench grinder is a bugger for this.

 

Actually they had to do it twice! They pulled the unit forward to do the rear connections (rear clearance is only 200mm) but forgot to push it back. I made sure they put epoxy grout in the old holes.
