Outside Slab Installation; Attaching Exhaust And Combustion Air Inlet Hoods; Horizontal Conversion Procedure - Daikin Maverick I Installation And Maintenance Manual

Outside Slab Installation

These units are designed certified for outdoor installation
only. Installation inside any part of a structure can result in
inadequate unit performance as well as property damage.
Installation inside can also cause recirculation of flue
products into the conditioned space resulting in personal
injury or death.
Typical outdoor slab installation is shown in
1
Select a location where external water drainage cannot
collect around unit.
2
Provide a level slab sufficiently high enough above grade
to prevent surface water from entering the unit
3
Locate the unit to provide proper access for inspection
and servicing as shown in
4
Locate unit where operating sounds will not disturb
owner or neighbors.
5
Locate unit so roof runoff water does not pour directly on
the unit. Provide gutter or other shielding at roof
level.Do not locate unit in an area where excessive snow
drifting may occur or accumulate.
6
Where snowfall is anticipated, the height of the unit
above the ground level must be considered. Mount unit
high enough to be above anticipated maximum area
snowfall and to allow combustion air to enter the
combustion air inlet.
7
Select an area which will keep the areas of the vent, air
intake, and A/C condenser fins free and clear of
obstructions such as weeds, shrubs, vines, snow, etc.
Inform the user accordingly.
