GENERAL
YORK Model B1HA units are factory assembled heat pumps designed for outdoor installation on a rooftop or a slab. Field-installed electric heater accessories are available to provide supplemental electric heat com­bined with electric cooling and heating.
The units are completely assembled on rigid, remov­able base rails. All piping, refrigerant charge, and elec­trical wiring is factory installed and tested. The units require only electric power and duct connections at the point of installation.
The electric heaters have nickel-chrome resistance wire elements and utilize single point power connection.
INSPECTION
As soon as a unit is received, it should be inspected for possible damage during transit. If damage is evident, the extent of the damage should be noted on the car­rier's freight bill. A separate request for inspection by the carrier's agent should be made in writing.
REFERENCE
Additional information on the design, installation, oper­ation and service of this equipment is available in the following reference forms:
REPLACEMENT PARTS
Contact your local York® parts distribution center for authorized replacement parts.
This product must be installed in strict compli­ance with the enclosed installation instructions and any applicable local, state, and national codes including, but not limited to, building, electrical, and mechanical codes.
Improper installation may create a condition where the operation of the product could cause personal injury or property damage.
De-energize the electrical power to the unit before attempting to inspect, repair or perform maintenance to the unit.

INSTALLATION
LIMITATIONS
These units must be installed in accordance with the following national and local safety codes.
1. National Electrical Code ANSI/NFPS No. 70 or Cana­dian Electrical Code Part 1, C22.1 (latest ed itions).
2. Local plumbing and waste water codes and other applicable local codes.
Refer to Table 1 for unit application data and to Table 4 for electric heat application data.
If components are to be added t o a unit to meet local codes, they are to be installed at the dealer's and/or the customer's expense.
Size of unit for proposed installation should be based on heat loss/heat gain calculations made in accor­dance with industry recognized procedures identified by the Air Conditioning Contractors of America.

installed components. Unit must be installed on a level roof curb or appropriate angle iron frame pro­viding adequate support under the compressor/ condenser section.
5. Maintain level tolerance of unit to 1/8" maximum.
RIGGING AND HANDLING
Care must be exercised when moving the unit. Do not remove any packaging until the unit is near the pla ce of installation. Rig unit with slings placed under the unit. Spreader bars of sufficient length should be used across the top of the unit.
BEFORE LIFTING A UNIT, MAKE SURE THAT ITS WEIGHT IS DISTRIBUTED EQUALLY ON THE CABLES SO THAT IT WILL LIFT EVENLY.
Units may also be moved or lifted with a fork-lift. Slot­ted openings in the skid are provided for this purpose. Forks must pass completely through the base.
Refer to Table 2 for unit weights and to Figure 1 for approximate center of gravity.

Use the following guidelines to select a suitable loca­tion for these units.
1. Unit is designed for outdoor installation only.
2. Condenser must have an unlimited supply of air. Where a choice of location is possible, position unit on either north or east side of building.
3. For ground level installation, a level pad or slab should be used. The thickness and size of the pad or slab used should meet local codes and unit weight. Do not tie the slab to the building foundation.
4. For roof top installation, be sure the structure will support the weight of the unit plus any field

FIGURE 1 - Center of Gravity CLEARANCES
All units require certain clearances for proper operation and service. Refer to Figure 4 for the clearances required for construction, servicing and proper unit operation.
Do not permit overhanging structures or shrubs to obstruct the condenser air discharge outlets.
341849-YIM-A-0108
DUCTWORK
These units are adaptable to downflow use as well as rear supply and return air duct openings. To convert to downflow, use the following steps:
1. Remove the duct covers found in the bottom return and supply air duct openings. There are four (4) screws securing each duct cover (save these screws to use later).
2. Install the duct covers, removed in step one, to the rear supply and return air duct openings. Secure with the four (4) screws used in step one.
3. Seal duct covers with silicone caulk.
Downflow units must have an “L”-shape d supply duct without any outlets or registers located below the outlet of the unit.
Duct work should be designed and sized according to the methods of the Air Conditioning Contractors of America (ACCA), as set forth in their Manual D.
A closed return duct system shall be used. This shall not preclude use of economizers or ventilation air intake. Flexible joints may be used in the supply and return duct work to minimize the transmission of noise.
CONDENSATE DRAIN
A condensate trap is required to be installed in the con­densate drain. The plumbing must conform to local codes. Use a sealing compound on male pipe threads. Install the condensate drain line (3/4“ NPTF) to spill into an open drain.
SERVICE ACCESS
Access to all serviceable components is provided by the following removable panels:
Blower service access
Electrical/Filter access
Compressor service access Refer to Figure 4 for locatio n of these access panels
and minimum clearances.
THERMOSTAT
The room thermostat should be located on an inside wall approximately 56" above the floor where it will not be subject to drafts, sun exposure or heat from electri­cal fixtures or appliances. Follow manufacturer's instructions enclosed with the thermostat for general installation procedure. Six color coded insulated wires (minimum #18 AWG) should be used to connect ther­mostat to unit. See Figure 2.
When fastening ductwork to side duct flanges on unit, insert screws through duct flanges only. DO NOT insert screws through casing. Outdoor ductwork must be insulated and waterproofed.
NOTE: Be sure to note supply and return openings. Refer to Figure 4 for information concerning rear and
bottom supply and return air duct openings.
FILTERS
A filter rack and high velocity filters are standard on three phase units.
Filters must always be used a nd must be kept clean. When filters become dirt laden, insufficient air will be delivered by the blower, decreasing your units effi­ciency and increasing operating costs and wear-and­tear on the unit and controls.
Filters should be checked monthly especially since this unit is used for both heating and cooling.
POWER AND CONTROL WIRING
Field wiring to the unit must conform to provisions of the current N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordinances. The unit must be electrically grounded in accordance with local codes or, in their absence, with the N.E.C./C.E.C. Voltage tolerances which must be maintained at the compressor terminals during starting and running conditions are indicated on the unit Rating Plate and Table 4.
The wiring entering the cabinet must be provided with mechanical strain relief.
A fused disconnect switch should be field provided for the unit. If any of the wire supplied with the unit must be replaced, replacement wire must be of the type shown on the wiring diagram.
Electrical line must be sized properly to carry the load. Each unit must be wired with a separate branch circuit fed directly from the meter panel and properly fused.
Refer to Figure 2 for typical field wiring and to the appropriate unit wiring diagram for control circuit and power wiring information.
