Step 3 — Rigging and Handling — To transfer the unit from the shipping platform to the storage or installation site, refer to the rigging label on the unit and these instructions.
All panels must be in place when rigging. Unit is not designed for handling by fork truck. Damage to unit may result.
Refer to Table 1 for ERV unit weights. Check lifting devices for capacity constraints.
Hook rigging shackles through the holes or lifting eyes in the ERV unit.
NOTE: Some 62M units have lifting eyes, some 62M units have holes in the ERV base rail. See Fig. 46.
Connect lifting straps and spreader bars. See Fig. 46. Spreader bars must be positioned to prevent cables from rubbing against the ERV unit.
Carefully lift the ERV unit and set on ERV roof curb. Do not drop the ERV unit onto the roof curb, as damage may occur. Avoid twisting or uneven lifting of the unit. Never lift the unit by the hoods or any means other than the provided lifting holes or eyes.
MOUNTING THE ERV UNIT INDOORS — The ERV unit can be mounted indoors. Follow all local and other applicable building codes.
All panels must be secured in place prior to lifting the ERV unit in to place. Follow all local and other applicable codes when lifting, locating and mounting the ERV unit. Damage to unit may result.
Locate the ERV Unit — Prior to locating the indoor ERV unit consider the intake and exhaust duct accessibility to outside walls or roof vents. When locating the ERV unit consider required service clearances.
See Table 1 for unit weights to determine if building struc- ture reinforcements are required.
Determine a Method for Mounting — The method for mount- ing and securing the ERV unit to the building structure must be field designed and installed. Mounting methods will vary depending upon specific jobsite conditions.
NOTE: Hardware and pieces to secure ERV unit to the build- ing structure must not interfere with the service clearances or duct requirements for the unit.
Lift the ERV Unit in Place — Secure the ERV unit to the building structure following all applicable local building codes.
Do not use the ERV duct system to support the ERV unit in any way. Follow all local and applicable building codes and manufacture and install the ductwork to the ERV unit per the duct opening connections. Equipment damage or personal injury may result.
