SINGLE PACKAGE HEAT PUMPS
INSTALLATION INSTRUCTION
MODELS B*CH 036 AND 048 (STYLE B)
GENERAL
YORK Model BCH units are single package heat pumps
designed for outdoor installation on a rooftop or a slab.
Supplemental electric heate rs are available as field-instal led
accessories.
The units are completely assembled on rigid, permanently
attached base rails. All pipi ng, refrigeran t charge, a nd electrical
wiring is factory-installed and tested. The units require only
electric power and duct co nnecti ons at the po int of i nstall ation.

The supplemental electric heaters have nickel-chrome
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 note d on the carrier’ s fre ight bil l. A se parate
request for inspection by the carrier’s agent should be made in
writing. Refer to Form 50.15-NM for additional information.

INSTALLATION
These units must be installed i n accordanc e with the curren t
edition of the following national and local safety codes:
In U.S.A.:
1. National Electrical Code ANSI/NFPA No. 70.
2. Local elec tric ut il ity requirements .
In Canada:
1. Canadian El ectrical Code C22.1
2. Canadian Installation Codes CAN/CGA-B149.1 and .2.
Refer to Table 1 for Unit Applic at ion Data.
If components are to be added to a unit to meet local codes, they
are to be installed at the dealer’s and / or the customer’ s expense .
511.06-N5Y
WARNING: The unit should not be installed in an area where mud
or ice could cause personal injury. Remember that
condensate wil l drip fro m the ou tdoor co il during heat
and defrost cycle s and that this co ndensate will freeze
when the temperat ure of the outdoor air is below 32°F.
RIGGING AND HANDLING
Exercise care when moving the unit. Do not remove any
packaging until the unit is near the place of installation. Rig the
unit by attaching chain or cable slings to the lifting holes
provided in t he base rails. Spreaders, wh ose length exceed s
the larges t dime nsion across the uni t, MUST be used acros s
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.
Size of unit for propos ed in st al la tion sh ou ld be ba sed on hea t

casing.
Outdoor ductw ork must be insulated and waterproofed.
Refer to Figure 6 for infor mation concerning side and bottom
supply and return air duct openings.
FILTERS
1" filters are supplied with each unit. 2" replacement filters may
be used with no modification to the filter racks. Filters must
always be installe d ahead of the evaporator c oil and must be
kept clean or rep laced wit h same siz e and type . Dirty filte rs will
reduce the capacity of the unit and will result in frosted coils or
safety shutdown. Minimum filter area an d required sizes are
shown in T able 3.
Figure 6. Several existing screws at the top of the unit and one
approximately midway down from the top will be used for
mounting the bracket. Screws should be lo os ened onl y - NOT

CAUTION: Do Not loosen compressor mounting bolts.
CONDENSATE DRAIN
Plumbing must conform to local codes. Use a sealing
compound on male pipe threads. Install a condensate drain line
from the 3/4" PVC f emale conn ection on the un it to spill into an
open drain.
NOTE: The condensate drain line MUST be trapped to provide
proper drainage. See Figure 2.

BLOWER SPEED SELECTION
Three blower motor speeds are available on the di rect-drive
units. The speed selection for the direct-drive units is
determined by the CFM and ESP requirements of the
applications. Al l units with belt-drive optio n have an a dj us ta ble
motor pulley to achieve the above conditions.
All direct-drive units are shipped with the black wire (labeled
#8) connected to the high speed tap on the blower motor. If a
lower blo wer speed is desire d, this wire shou ld be mov ed to the
medium or low speed tap on the motor.
DISCONNECT SWITCH BRACKET FOR UNITS
WITH OPTIONAL BELT-DRIVE BRACKET
A special bracket for mounting a field-supplied disconnect
switch is provided in each unit ordered with an optional
belt-drive supp ly air blower. The bracket is shipped inside the
blower compartment taped to the top of the blower housing.
Install the bracket on the left hand side of the unit as shown in
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
thermostat for general installation procedure. Color coded
insulated wires (#18 AWG) should be used to connect
thermostat to unit. See Figure 3 for w iring det ai ls.
NOTE: On units with econ omizer, remove jumper "J1" from
termin als 8 and 10 on plug connector J3/P 7 on the
relay board in the unit control box. Refer to the unit
wiring labels located on the inside of the control box
access panel.
An "Emergency Heat" position is provided with the thermostat.
In the "Emergency Heat" position, the thermostat will allow
electric resistance heat only. The compressor will be locked
out. A pilot light on the thermostat will indicate that the switch
is on "EM HT".
POWER AND CONTR OL WIRING
Field wiring to the unit must conform to provisions of the National
Electrical Code (NEC) ANSI/NFPA No. 70 (in U.S.A.), current
Canadian Electrical Code (CEC) C22.1 (in Canada) and/or local
ordinances. The unit must be electrically grounded in accordance
with the NEC and CEC (as specified above) and/or local codes.
V oltage tolerances which m ust be maintained at the compressor
terminals during starting and running conditions are indicated on
the unit Rating Plate and T ab le 1.
The wiri ng har n ess fu rni shed w ith t his un it is an int egral part
of a UL and C.G.A. design certified unit. Field alteration to
comply with electrical codes should not be required.
A disconnect switch should be field provided for the unit. The
switch must be separate from all other circuits. Refer to Figure
6 for installation location. 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 lines must be sized properly to carry the load. USE
COPPER CONDUCTORS ONLY. Each unit must be wired with
a separate branch circuit fed directly from the meter panel and
properly protected.
CAUTI ON: When connecting electrical power an d contro l wi r-
ing to the unit, waterproof type connectors MUST
BE USED so that water or moisture cannot be
drawn into the unit during normal operation. The
above waterproofing conditions will also apply
when install ing a field-sup plied disconnect switch.
Refer to Figure 3 for typical field wiring and to the appropriate
unit wiring diagram for control circuit and power wiring
information. Refer to Tables 9 and 10 for electrical data.

ELECTRIC HEATERS
Supplemental electric heaters may be ordered as a
field-installed accessory. Refer to Form 530.18-N7.1V for
installation instruction . The se UL and C .G. A. appro ve d heaters
are located within the central compartment of the unit (see
Figure 6 for ac cess panel) wi th the heati ng elements e xtendi ng
into the supply air chamber.
Fuses are supp li ed , whe re r eq ui red , by the factory. Some KW
sizes require fuses and others do not. Refer to the electric
heater accessory installation instruction for the heater electrical
data.
