5. TRANSPORTATION DAMAGE
All units are packed securely in shipping container.
All units should be carefully inspected upon arrival for
damage. In the event of damage, the consignee should:
1. Note on delivery receipt of any damage to container.
2. Notify carrier promptly, and request an inspection.
3. In case of concealed damage, the carrier must be
notified as soon as possible within 15 days after
delivery.
4. Claims for any damage, apparent or concealed,
should be filed with the carrier, using the following
supporting documents:
A. Original Bill of Lading, certified copy, or
indemnity bond.
B. Original paid freight bill of indemnity in lieu
thereof.
C. Original invoice or certified copy thereof
showing trade and other discounts or
deductions.
D. Copy of the inspection report issued by
carrier’s representative at the time damage is
reported to carrier.
6. INSTALLATION
Size of unit for proposed installation should be based
on heat loss/heat gain calculations made according
to methods of Air Conditioning Contractors of
America (ACCA). The air duct should be installed
in accordance with the Standards of the National
Fire Protection Association for the Installation of Air
Conditioning and Ventilating Systems of Other Than
Residence Type, NFPA No. 90A, and Residence Type
Warm Air Heating and Air Conditioning Systems,
NFPA No. 90B. Where local regulations are at a
variance with instructions, installer should adhere to
local codes.
7. WALL MOUNTING INFORMATION
1. Two holes for the supply and return air
openings must be cut through the wall as
detailed in Figure 4.
2. On wood-frame walls, the wall construction
must be strong and rigid enough to carry the
weight of the unit without transmitting any unit
vibration.
3. Concrete block walls must be thoroughly
inspected to insure that they are capable of
carrying the weight of the installed unit.
2. The WG3S2, WG4S2 and WG5S2 models are
suitable for 0 inch clearance on the installation
mounting wall and to the top. For all models the
supply air duct flange and the first 3 feet of
supply air duct require a minimum of 1-inch
clearance to combustible material.
3. Locate and mark lag bolt locations and bottom
mounting bracket location.
4. Mount bottom mounting bracket.
5. Hook top rain flashing under back bend of top.
Top rain flashing is shipped secured to the right
side of the back.
6. Position unit in opening and secure with 5/16
lag bolts; use 7/8 inch diameter flat washers on
the lag bolts. Use lag bolts long enough to
support the unit’s weight when mounted to the
structure. This length may be dependant on the
type of construction.
7. Secure rain flashing to wall and caulk across
entire length of top. See Figure 3.
8. On side-by-side installations, maintain a
minimum of 20 inches clearance on right side
to allow access to control panel and burner
compartment, and to allow proper airflow to the
outdoor coil. Additional clearance may be
required to meet local or national codes.
8. MOUNTING THE UNIT
1. These units are secured by wall mounting
brackets which secure the unit to the outside
wall surface at both sides. A bottom mounting
bracket is provided for ease of installation but
is not required.
CAUTION
If the bottom bracket is used, be certain the
bracket is secured to the outside wall surface
in a way sufficient to support the entire
weight of the unit during installation until side
mounting brackets are secured.
WARNING
Failure to provide the one inch clearance
between the supply duct and a combustible
surface for the first three feet of duct can result
in fire causing damage, injury or death.
