Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors. |
k |
Based on 75°C copper wire. All wiring must conform to the National Electric Code (NEC) and all local codes. |
lThese "Minimum Circuit Ampacity" values are to be used for sizing the field power conductors. Refer to the National Electric Code (latest version), Article 310 for power conductor sizing. CAUTION: When more than one filed power conductor circuit is run through one conduit, the conductors must be derated. Pay special attention to Note * of Table 310 regarding Ampacity Adjustment Factors when more than 3 conductors are in a raceway.
SHIPPING DAMAGE
Upon receipt of equipment, the carton should be checked for external signs of shipping damage. If damage is found, the receiving party must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier’s agent.
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.
These instructions and any instructions packaged with any separate equipment required to make up the entire air conditioning system should be carefully read before beginning the installation. Note particularly “Starting Procedure” and any tags and/or labels attached to the equipment.
While these instructions are intended as a general 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 1 for information on codes and standards.
Size of unit for a proposed installation should be based on heat loss 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.
DUCT WORK
All duct work, supply and return, must be properly sized for the design air flow 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.
Refer to Table 9 for maximum static pressure available for duct design.
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 1 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 first three feet of duct attached to the outlet air frame is required. See Wall Mounting Instructions and Figures 4 and 5 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.
CAUTION
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 inches.
Any grille that meets the 5/8 inch louver criteria, may be used. It is recommended that Bard Return Air Grille Kit RG-2 thru RG-5 or RFG-2 thru RFG-5 be installed when no return duct is used. Contact distributor or factory for ordering information. If using a return air filter grille, filters must be of sufficient 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.

FILTERS
A 1 inch throwaway filter is supplied with each unit. The filter slides into position making it easy to service. This filter can be serviced from the outside by removing the service door. A 1 inch washable filter and 2 inch pleated filter are also available as optional accessories. The internal filter brackets are adjustable to accommodate the 2 inch filter by bending down the tabs to allow spacing for the 2 inch filters.
All capacity, efficiency and cost of operation information as required for Department of Energy “Energyguide” Fact Sheets is based upon the fresh air blank-off plate in place and is recommended for maximum energy efficiency.
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.
FRESH AIR INTAKE
All units are built with fresh air inlet slots punched in the service panel.
If the unit is equipped with the 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 minium blade position stops must be installed. See Figure 2.
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.
