3.5 Foundation for the outdoor unit
A permanent foundation is required beneath the
outdoor unit. The foundation must meet the load
bearing requirements of the outdoor unit (see
section 13, Specification).
• Provide for frost-free drainage (e.g. a gravel
bed with a frost-free connection to a drain)
for condensation that forms on the outdoor
unit.
• Where refrigerant lines are to be laid in the
ground, ensure correct positioning of the
pipe liner when laying the foundations.
• Use rigid underground sewage pipes or
flexible, double-skinned cable ducts (smooth
on the inside) for the pipe liner.
• This must be done in accordance with the
relevant Building Codes of Practice and
regulations.
Take the expected wind loads at the
installation site into consideration.
Ensure that the outdoor unit is
adequately secured to the foundation
to prevent it from tipping over due to
wind loads.
CAUTION: Slipping hazard
If drainage for condensation is
inadequate, ice can build up in winter
in the area around the outdoor unit.
- Ensure drainage for
condensation is sufficient even
at low temperatures.
- Ensure that no ice is formed,
especially around walking
surfaces and entrances around
the outdoor unit.
NOTE
Insulation used beneath the soil must
be made of a closed-cell material.
Otherwise, the thermal insulation of
the material will be impaired.
