RIGGING AND HANDLING
Exercise care when moving the unit. Do not remove any packaging until the unit is near the place of installa- tion. Rig the unit by attaching chain or cable slings to the round lifting holes provided in the base rails. Spreaders, whose length exceeds the largest dimen- sion across the unit, MUST BE USED. Refer to Figure 1.
Units may also be moved or lifted with a forklift, from the side only, providing that an accessory skid is used.
LENGTH OF FORKS MUST BE A MINIMUM OF 90".
Refer to the Physical Data Table 7 for unit weights and to the Figures 2 or 12 for approximate center of gravity.
Before lifting a unit, make sure that all panels are in place and that its weight is distributed equally on all cables so it will lift evenly.

An adhesive backed label is provided over the outside of the combustion air inlet opening to prevent moisture from entering the unit, which could cause damage to electrical components. Allow this closure label to remain in place until the combustion air hood is to be installed (refer to Vent and Combustion Hood Figure 8).
CLEARANCES
All units require certain clearances for proper operation and service. Installer must make provisions for ade- quate combustion and ventilation air in accordance with Section 5.3, Air for Combustion and Ventilation of the National Fuel Gas Code, ANSI Z223.1 (in U.S.A.) or Sections 7.2, 7.3 or 7.4 of Gas Installation Codes
