any other packed accessories, and promptly notified the freight company of any and all damages. Typically, it is
the customer’s responsibility to claim freight damage.
• The unit is very heavy and somewhat top-heavy! Exercise due caution when handling to avoid personal in ury or
damage to the equipment. Take necessary precautions to avoid damaging the hood base skirt or stand, as
applicable.
• Exercise care when removing the wooden framing from around the unit to avoid any exposed nails or staples.
• Failure to comply with these CAUTION notices may result in minor to moderate in ury, damage to equipment or
property, and void the warranty.
2.02 npacking
Unit is shipped on a wooden pallet, secured by high-tensile plastic strapping and wrapped in machine-applied
stretch wrap. In most cases a wooden framework is built around the unit for added protection. Unpack unit as
follows:
1. Position pallet in an area that provides adequate space for unpacking.
2. Remove the plastic stretch wrap, strapping and other packaging materials as necessary.
3. Carefully remove any wooden supports and/or framework that might be attached.
4. Locate and secure the envelope containing Warranty Card and any other documentation or hardware provided
for installation.

3. DO NOT attach additional ductwork to the exhaust outlet in an attempt to redirect airflow. Resulting back
pressure can significantly reduce hood capture and result in unsatisfactory performance.
4. When installing the GVH-F floor stand version, be sure the floor area is relatively level. The hood stand has
ad ustable leveling legs and after final positioning, ad ust the legs to level unit, side to side, front to back and
corner to corner.
The hood stand must be anchored to the floor using appropriate methods. Front legs have floor plates for this
purpose.
1. Obtain carton with ad ustable legs ... two (2) legs are floor-plate style; the other two (2) are standard style.
2. With appliance resting on a stable surface, have helpers tilt the unit forward and hold.
3. Install the two (2) rear legs (standard) into thread holes on bottom of side stand, screw in clockwise until
hand tight. Ta e care not to cross-thread ... leg should turn fairly easy until tight.
4. Have helpers tilt unit backward onto the installed rear legs, giving access to front of stand. Repeat the
process for front two (2) legs (floor-plate).
