NOTES
1. Under certain conditions these clearances may be encroached upon.
2. This is a visual reference for all Series 100 units.
RIGGING
Proper rigging and handling of the equipment is mandatory during unloading and setting
it into position to retain warranty status.
Spreader bars must be used by cranes to prevent damage to the unit casing. All lifting lugs
must be used when lifting the single package unit unit. Fork lifts will damage the single
package unit and are not recommended.
Care must be taken to keep the unit in the upright position during rigging and to prevent
damage to the watertight seams in the unit casing. Avoid unnecessary jarring or rough
handling.
UNIT PLACEMENT
•
Elevated
– Elevated roof curbs or dunnage steel can be used to support the unit in
order to raise it to specific heights. When this type of placement is required, be sure
to keep unit access in mind. Cat walks or other forms of unit access may be required
to one or both sides of the unit, depending on your area of the country and the local
codes that are enforced. Please check with local officials to ensure the application
conforms to local codes and regulations.
•
Ground Level Locations
– It is important that the units be installed on a substantial
base that will not settle, causing strain on the refrigerant lines and sheet metal and
resulting in possible leaks. A one-piece concrete slab with footers extended below
the frost line is highly recommended. Additionally, the slab should be isolated from
the main building foundation to prevent noise and vibration transmission to the build-
ing structure.
For ground level installations, precautions should be taken to protect the unit from
tampering by, or injury to, unauthorized persons. Erecting a fence around the unit is
common practice.
•
Roof curb
– Johnson Controls offers optional roof curbs designed specifically for the
Series 100 footprint. These curbs come in full perimeter or open condenser models
and are shipped disassembled and require field assembly and installation. For bot
-
tom supply and return openings, the curbs have matching connections to ease instal-
lation. A pipe chase that matches the single package unit pipe chase is also included
in the curb footprint for through-the-curb utility connections.
The curb should be located according to the location recommendations above, and
properly sealed to prevent moisture and air leakage into and out of the duct system.
Flexible collars should be used when connecting the duct work to prevent unit noise
transmission and vibration into the building.
Duct work should be supported independently of the unit.
