The whole of the base of the Enviroair unit should be installed on
a foundation. When using a vibration-proof mat, it should also be
positioned the same way. When installing the Enviroair unit on a
field supplied frame, use metal plates to adjust the frame width
for stable installation as shown in below figure.
Recommended metal plate size
• (Field-supplied) material: hot-rolled mild steel
• Plate (SPHC) plate thickness: 4.5 T
6.2 Place Provision
Concrete foundation
• Foundation shall be on a level surface and it is recommended
to be 100-300 mm higher than ground level.
• Use M10 anchor bolts to fix the unit to the foundation.
(Foundation bolts, nuts and washers are not included,
and must be field supplied).
• Drain water might turn into ice on cold weather areas.
Therefore, when installing the unit on a roof or a
veranda, avoid the draining on a public area since it
may become slippery.
