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. 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 dam-
age 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 –
TempMaster offers optional roof curbs designed specifically for the
TempMaster OmniElite footprint. These curbs come in full perimeter or open con-
denser models and are shipped disassembled and require field assembly and instal
-
lation. For bottom supply and return openings, the curbs have matching connections
to ease installation. A pipe chase that matches the single package unit pipe chase is
also included in the curb footprint for through-the-curb utility connections.
