LIFTING AND
LOCATING
Select a suitable location for the unit, where the unit will not be subject to damage.
1. Indoor units may not work correctly if the equipment-room temperature goes below 70°F (21°C).
2. The location must not contain corrosive-chemical storage, or connect to any space that contains corrosive-
chemical storage.
3. The location must not be in a natatorium or spa room, or any space where the exterior of the unit would
be exposed to chloramines outgassing from a pool.
4. There are other requirements for suitability - see other pages in this section.
Allow working clearances as shown below. Inadequate working spaces may compromise workplace safety.
Inadequate working spaces may preclude proper maintenance, such as filter and belt replacement. Inadequate
working space may prevent component replacement should that become necessary.
Spacing requirements are also subject to applicable electrical and mechanical codes. This is particularly true
where optional built-in electrical disconnects are provided. Check with your local code-enforcement authorities.
Where access doors are hinged, all doors must be able to open at least 90°.
For units with hooded air intakes allow at least 3 feet (1 meter) of clear space around the hood for smooth intake
airflow. Intake air hoods should be suitably separated from such sources of contamination as drain vents and
burner flues. See appropriate codes and standards.
Some horizontal units may have condensate-drain connections on the bottom of the unit. Clearances and pipe
connections should be completed before the unit is actually placed.
Service Clearances
Risk of falling. Can cause injury or death.
Depending on the size and location of this product, some installation, service, and
maintenance procedures could expose personnel to the risk of injury or death by falling.
Designs should include adequate service and maintenance access. Use fall-
