QMaximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.
RBased on 75° C copper wire. All wiring must conform to NEC and all local codes.
SMaximum KW that can operate with heat pump on.
TThese “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electric Code (latest revision), article 310, for power conductor sizing. CAUTION: When more than one field power conductor circuit is run through one conduit the conductors must be derated. Pay special attention to note 89 of table 310 regarding Ampacity Adjustment Factors when more than 3 are in a raceway.
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
Any heat pump is more critical of proper operating charge and an adequate duct system that a straight air conditioning unit. 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 10 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 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 first three feet of duct attached to the outlet air frame is required. See Pages Wall Mounting Instructions and Figure 3 for further details.
