B.MOVING AND HANDLING THE HUMIDIFIER
(1)The NH Outdoor Series humidifier is bolted to a shipping skid for easy transportation. While still attached the skid, the humidifier can be lifted to a rooftop or other location using a forklift or crane. The unit can also be positioned for wall mounting using a forklift as long as the skid is attached, although it may be easier to manually lift the unit onto its wall brackets. Installation on a curb requires guide lifting of the unit. Observe the following precautions when moving and positioning the humidifier:
(a)When lifting by crane, ensure that the unit is protected from physical damage by the tethers and lifting equipment.
(b)When lifting by forklift, ensure that unit is properly balanced and secured to prevent tipping.
(c)Use proper lifting techniques when manually lifting. Often several people will be required to lift the unit.
(d)Remove the cabinet doors before manually lifting the unit.
(e)Ensure that the humidifier is the proper model, capacity, and voltage for the specific location.
