GENERAL INSTALLATION GUIDELINES
Rigging and Lifting Instructions
Be very careful when transporting the product. There is a risk of the product falling and causing physical injury.
• Use appropriate moving equipment to transport each frame; ensure the equipment is capable of supporting the weights listed.
• Some products use polypropylene bands for packaging.
Do not use polypropylene bands to lift the unit.
• Support the outdoor unit at a minimum of four points to avoid slippage from rigging apparatus.
Wear protective gloves and safety goggles when handling equipment. Sharp edges may cause personal injury.
Dispose of the packing materials safely.
• Packing materials, such as nails and other metal or wooden parts, may cause puncture wounds or other injuries.
• Tear apart and throw away plastic packaging bags so that children may not play with them and risk suffocation and death.
CAUTION
• Make sure the outdoor unit is in its original packaging to avoid damage during local transport.
• At the time of delivery, the package must be checked for any damage (exterior and interior). Report any damage to the carrier claims
agent immediately.
• Handle the outdoor unit with care. Keep the outdoor unit upright to avoid damaging inside components.
• If a forklift is to transport the outdoor unit, the forklift arms must pass through the openings at the bottom.
• If a crane is to suspend the outdoor unit, it is recommended that two (2) ropes at least twenty-three (23) feet in length be used. Pass
the ropes under the unit. Pass the rope through the two (2) forklift slots each at the front and rear of the outdoor unit.
•
To prevent damage to the outdoor unit, always lift the unit with the ropes attached at four (4) points at an angle of ≤40°.
• Always include padding to protect the outdoor unit from rope damage, and take into consideration the outdoor unit’s center of gravity.
Anchoring the Outdoor Unit
• Tightly anchor the outdoor unit with a bolt and nut to a concrete or rigid platform.
• When installing on a wall (with field-supplied brackets), roof, or rooftop, securely anchor the
mounting platform with nails, taking into consideration the possibility of strong winds or earth-
quakes.
• If there is a possibility of vibration from the outdoor unit transmitting to the building, add an
anti-vibration material to the platform.
