Installation Instructions

4 Installation

4.1 Pre-Installation

Before installation, carefully check the following:
1. Unit should be installed in accordance with national and local
safety codes, including but not limited to ANSI/NFPS No. 70, local
plumbing and wastewater codes and any other applicable codes.
2. For rooftop installation, be sure the structure has enough strength
to support the weight of unit. Unit must be installed on a fi eld
supplied roof curb or rack and leveled.
3. For ground level installation, a fi eld supplied level slab must be
used.
4. Condenser airfl ow should not be restricted.
5. On applications when a roof curb is used, the unit must be
positioned on the curb so the front of the unit is tight against the
curb.

4.2 Rigging and Lifting

Figure 9
Exercise care when moving the unit. Do not remove any packaging until
the unit is near the place of installation. Rig the unit by attaching chain or
cable slings to the lifting holes provided in the base rails. Spreader bars,
whose length exceeds the largest dimension across the unit, MUST be
used across the top of the unit.

Before lifting, make sure the unit weight is
distributed equally on the rigging cables so it will lift
evenly.

All panels must be secured in place when the unit is
lifted. The condenser coils should be protected from
rigging cable damage with plywood or other suitable
material.
NOTICE:
