GENERAL
The equipment covered in this manual is to be installed by trained, experienced service and installation technicians.
The refrigerant system is completely assembled and charged. All internal wiring is complete.
The unit is designed for use with or without duct work. Flanges are provided for attaching the supply and return ducts.
These instructions explain the recommended method to install the air cooled self-contained unit and the electrical wiring connections to the unit.
recommended guide, they do not supersede any national and/or local codes in any way. Authorities having jurisdiction should be consulted before the installation is made. See Page 3 for information on codes and standards.
Size of unit for a proposed installation should be based on heat loss/gain calculation 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.
Manual 2100-527H Page 4 of 29
DUCT WORK
All duct work, supply and return, must be properly
sized for the design airow requirement of the
equipment. Air Conditioning Contractors of America (ACCA) is an excellent guide to proper sizing. All duct work or portions thereof not in the conditioned space should be properly insulated in order to both conserve energy and prevent condensation or moisture damage.
Design the duct work according to methods given by the Air Conditioning Contractors of America (ACCA). When duct runs through unheated spaces, it should be insulated with a minimum of one inch of insulation. Use insulation with a vapor barrier on the outside of the insulation. Flexible joints should be used to connect the duct work to the equipment in order to keep the noise transmission to a minimum.
A 1/4 inch clearance to combustible material for the
rst three feet of duct attached to the outlet air frame is
required. See Wall Mounting Instructions and Figures 3A, 3B and 4 for further details.
Ducts through the walls must be insulated and all joints taped or sealed to prevent air or moisture entering the wall cavity.
Some installations may not require any return air duct. A metallic return air grille is required with installations not requiring a return air duct. The spacing between louvers on the grille shall not be larger than 5/8 inch.
FILTERS
A 1-inch throwaway lter is standard with each unit. The lter slides into position making it easy to service. This lter can be serviced from the outside by removing the lter access panel. A 1-inch washable lter and 2-inch pleated lter are also available as optional accessories. The internal lter brackets are adjustable to accommodate the 2-inch lter by bending two (2) tabs down on each side of the lter support bracket.
FRESH AIR INTAKE
All units are built with fresh air inlet slots punched in the service door.
If the unit is equipped with a fresh air damper assembly, the assembly is shipped already attached to the unit. The damper blade is locked in the closed position. To allow the damper to operate, the maximum and minimum blade position stops must be installed. See Figure 1.
All capacity, efciency and cost of operation
information is based upon the fresh air blank-off plate in place and is recommended for maximum energy
efciency.
The blank-off plate is available upon request from the factory and is installed in place of the fresh air damper shipped with each unit.
Any grille that meets with 5/8 inch louver criteria may be used. It is recommended that Bard Return Air Grille Kit RG2 through RG5 or RFG2 through RFG5 be installed when no return duct is used. Contact distributor or factory for ordering information. If using a return air
lter grille, lters must be of sufcient size to allow a
maximum velocity of 400 fpm.
NOTE: If no return air duct is used, applicable
installation codes may limit this cabinet to installation only in a single story structure.
FIGURE 1
FRESH AIR DAMPER
CONDENSATE DRAIN
A plastic drain hose extends from the drain pan at the top of the unit down to the unit base. There are openings in the unit base for the drain hose to pass through. In the event the drain hose is connected to a drain system of some type, it must be an open or vented type system to assure proper drainage.

INSTALLATION INSTRUCTIONS
WALL MOUNTING INFORMATION
1. Two holes for the supply and return air openings must be cut through the wall as shown in Figure 3.
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.
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, attached to skid for shipping, is provided for ease of installation, but is not required.
2. The unit itself is suitable for 0 inch clearance,
but the supply air duct ange and the rst 3 feet
of supply air duct require a minimum of 1/4 inch clearance to combustible material. However, it is generally recommended that a 1-inch clearance is used for ease of installation and maintaining the required clearance to combustible material. See Figure 3 for details on opening sizes.
3. Locate and mark lag bolt locations and bottom mounting bracket location. See Figures 3A & 3B.
4. Mount bottom mounting bracket.
5. Hook top rain ashing, attached to front - right of supply ange for shipping, under back bend of top.
6. Position unit in opening and secure with 5/16 lag bolts;
use 7/8 inch diameter at washers on the lag bolts.
7. Secure rain ashing to wall and caulk across entire
length of top. See Figures 3A & 3B.
WARNING
Failure to provide the 1/4 inch clearance
between the supply duct and a combustible surface for the rst 3 feet of duct can result in re causing damage, injury or death.
PLACEMENT
1. On side-by-side installations, maintain a minimum of 20 inches clearance on right side to allow access to control panel and heat strips, and to allow proper
airow to the outdoor coil. Additional clearance
may be required to meet local or national codes.
2. Care should be taken to ensure that the recirculation and obstruction of condenser discharge air does not occur. Recirculation of condenser discharge air can be from either a single unit or multiple units. Any object such as shrubbery, a building or a large object can cause obstructions to the condenser discharge air. Recirculation or reduced
airow caused by obstructions will result in reduced
capacity, possible unit pressure safety lockouts and reduced unit service life.
Units with a blow through condenser, such as
the S**H 10 EER units, it is recommended that a minimum distance of 15 feet between the front of the unit and any barrier or 20 feet between the fronts of two opposing (facing) units.
Units with a draw through condenser, such as the
W**H 10 EER units, it is recommended that a minimum distance of 10 feet between the front of the unit and any barrier or opposing (facing) unit.
8. For additional mounting rigidity, the return air and supply air frames or collars can be drilled and screwed or welded to the structural wall itself (depending upon wall construction). Be sure to observe required clearance if combustible wall.
