should be high enough above grade so that water from |
| ||||
|
|
|
| ||
higher ground will not collect around the unit. The slab |
|
|
|
| |
should have a slope tolerance as described in figure 5, |
| Roof Damage! |

detail B. |
| This system contains both refrigerant and oil. Some | |||

described in figure 5, detail D. |
| rubber to swell when it comes into contact with oil. The | |||
|
| rubber will then bubble and could cause leaks. Protect | |||
ELEVATING THE UNIT |
| the roof surface to avoid exposure to refrigerant and oil | |||
Units are outfitted with elongated support feet as illustrated |
