GENERAL
YORK Model B1HAunits 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 ele-
ments and utilize single point power connection.
INSPECTION
As soon as a unit is received, it should be inspected for pos-
sible 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. Refer to Form 50.15-NM for additional in-
formation.

CLEARANCES
All units require certain clearances for proper operation and
service. Refer to Figure 3 for the clearances required for
combustion, construction, servicing and proper unit opera-
tion.
WARNING:Do not permit overhanging structures or shrubs to
obstruct the condenser air discharge outlet.
DUCT WORK
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 secur-
ing each duct cover (save these screws to use later).
2. Installtheductcovers,removedinstepone,totherearsup-
ply 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”-shaped 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 pre-
clude use of economizers or ventilation air intake. Flexible
joints may be used in the supply and return duct work to mini-
mize the transmission of noise.
CAUTION: When fastening duct work to the side duct flanges on
theunit,insertthescrewsthroughtheductflangesonly.
DONOTinsertthescrewsthroughthecasing.Outdoor
duct work must be insulated and waterproofed.
NOTE: Be sure to note supply and return openings.
Refer to Figure 3 for information concerning rear and bottom
supply and return air duct openings.
FILTERS
Singlephaseunitsareshippedwithoutafilterandistheresponsi-
bilityoftheinstallerto securea filterinthe returnair ductwork or
install a Filter/Frame Kit (1FF0114).
A filter rack and high velocity filters are standard on three
phase units.
Filters must always be used and 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-and-tear on the unit and controls.
Filters should be checked monthly especially since this unit is
used for both heating and cooling.
CONDENSATE DRAIN
A condensate trap is required to be installed in the conden-
sate drain. The plumbing must conform to local codes. Use a
sealing compound on male pipe threads. Install the conden-
sate drain line (
34
“ NPTF) to spill into an open drain.

The room thermostat should be located on an inside wall ap-
proximately 56" above the floor where it will not be subject to
drafts, sun exposure or heat from electrical fixtures or appli-
ances. Follow manufacturer's instructions enclosed with the
thermostat for general installation procedure. Six color coded
insulated wires (minimum #18 AWG) should be used to con-
nect thermostat to unit. See Figure 2.
POWER AND CONTROL WIRING
Field wiring to the unit must conform to provisions of the cur-
rent N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordi-
nances. 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 con-
ditions are indicated on the unit Rating Plate and Table 3.
The wiring entering the cabinet must be provided with me-
chanical strain relief.
Afused disconnect switch should be field provided for the unit.
If any of the wire supplied with the unit must be replaced, re-
placement wire must be of the type shown on the wiring dia-
gram.
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 informa-
tion.

been completed:
1.Remove the t o ¼ inch dot plugs in the duct panel.
2.Insert at least 8 inches of ¼ inch tubing into each of these
holes for sufficient penetration into the airflo on both sides
of the indoor coil.
3.Using an inclined manometer, determine the pressure drop
across the dry evaporator coil. Since the moisture on an
evaporator coil may vary greatly, measuring the pressure
drop across a et coil under field conditions ould be inac-
curate. To ensure a dry coil, the compressors should be de-
activated hile the test is being run.
4.Kno ing the pressure drop across a dry coil, the actual
CFM through the unit can be determined from the curve in
Coil Delta P vs. Supply Air CFM figure.
WARNING! Failure to properly adjust the total system air
quantity can result in extensive system damage.
After readings have been obtained, remove the tubes and
reinstall the t o ¼ inch plugs removed in Step 1.
NOTE: De-energize the compressors before taking any test
measurements to ensure a dry indoor coil.

Anti-short Cycle Timer
Thisunithasan anti-shortcycle timerbuiltintothe defrostcon-
trol.This timer will not permit thecompressortostartwithin five
minutesafterthecompletionofthe lastcycle orpowerinterrup-
tion. To bypass the anti-short cycle feature, short the “TEST”
pins together for 2 seconds.
The following sequences of operation are based on using a
standard single-stage heat pump thermostat.
Cooling Operation
WITH POWER TO UNIT AND THERMOSTAT IN COOLING
MODE.
1. If the fan switch on the thermostat is in the “ON” position,
the 24 volts at “G” will energize the “K1" relay on the fan
control board, close the ”K1" relay contacts, and energize
the indoor blower motor. If the fan switch on the thermostat
isinthe“AUTO”position, the blower will operate only when
there is a call for cooling by the thermostat.
2. Onacallforcooling,thethermostatwill send 24 voltsto“Y”
and “O” on the fan control board. After the anti-short cycle
period is complete,The 24 volt signal will energize contac-
tor “M1", and the reversing valve solenoid. Power will be
supplied to the compressor and outdoor fan motor, and the
reversing valve will switch to the cooling position. If the fan
switch on the thermostat is on the ”AUTO" position, the fan
control will energize the indoor blower.
3. When the demand for cooling has been satisfied, the 24
volt“Y” signalisremoved andthe“M1" contactorwillbede-
energized. If the fan switch on the thermostat is in the ”ON"
position, the indoor blower will continue to run. If the fan
switchisinthe“AUTO”position,the“K1"relaywillopenand
de-energize the indoor blower motor after a 60 second de-
lay,
Heating Operation
WITH POWER TO UNIT AND THERMOSTAT IN HEATING
MODE.
1. If the fan switch on the thermostat is in the “ON” position,
the 24 volts at “G” will energize the “K1" relay on the fan
control board, close the ”K1" relay contacts, and energize
the indoor blower motor. If the fan switch on the thermostat
isinthe“AUTO”position, the blower will operate only when
there is a call for heating by the thermostat.
2. Ona callforheating, thethermostatwillsend24 voltsto “Y”
on the fan control board. After the anti-short cycle period is
complete, the 24 volts signal will energize contactor coil
“M1"andpowerwillbesuppliedtothecompressorandout-
door fan motor. The reversing valve will remain in the heat-
ing position. If the fan switch on the thermostat is in the
”AUTO" position, the fan control will energize the indoor
blower.
3. For units equipped with supplementary electric heat, if the
heat pump cannot meet the demand, the thermostat “W”
willsend24voltsto “W2" on thefan controlboard. This sig-
nal will also be sent through the defrost control terminals
”W" and “W1/66" and back to the fan control ”W1". This 24
volt signal will energize all stages of electric heat.
4. When the heating demand is satisfied, the electric heat will
bede-energized when the 24 volt “W” signal is removed,
and the “M1" contactor will be de-energized when the 24
volt ”Y" signal is removed. If the fan switch on the thermo-
statisinthe“ON”position,theindoorblowerwillcontinueto
run.Ifthefanswitchisinthe“AUTO”position,the“K1"relay
willopenandde-energize theindoorblowermotorafter the
appropriate time delay.
Please refer to Tables 7 and 8 for more information.
Defrost Operation
The minimum time between defrosts can be field selected at
30, 60 or 90 minutes. The default time is 90 minutes if the
jumper is not installed.
Defrostwill initiatewhen the defrostsensor,located ontheout-
doorcoil, senses a temperaturebelow31°F and when thetime
since the last defrost is greater than the selected time on the
defrost control. The defrost cycle terminates when either the
defrost sensor reaches 55°F or the unit has been in defrost
mode for 10 minutes. If the room thermostat opens during de-
frost,theunitwillresumeoperationindefrostwhenthethermo-
stat re-closes.
During the defrost mode, the defrost control will provide a 24
volt signal from terminal “W1/66" to the fan control terminal
”W1".Thissignalwillenergizeelectricheatstage1,iftheunitis
so equipped.
For trouble shooting purposes, the defrost cycle can be manu-
ally initiated by shorting the “TEST” pins together for 5 sec-
onds.Defrostwillterminatenormallyduringthe“TEST”mode.
Heat Pump Safety Switch Operation
If the unit is equipped with the field installed upgrade safety
package, the refrigeration system will be protected against
high or low refrigerant pressure and low indoor coil tempera-
ture.Ifanyofthesethreesafetyswitchesopens,theunitwillbe
shutoffforthe5minuteanti-shortcycletime. Oncethis hasex-
pired, a six hour elapsed run timer begins. If a second opening
of a safety switch occurs during this six hour period, the com-
pressor will be locked out.
Resetting the lockout function is accomplished by;
1. Removing power from the control's thermostat 1st stage
(Y)inputforatimenottoexceed5seconds(ON-OFF-ON).
2. Removing power from “R” for more than 2 seconds.
3. Shortingthe“TEST”pinstogetherformorethan2seconds.
Electric Heat Limit Switch Operation
Thelimitswitchrespondstoover temperatureconditions inthe
airduct. Opening of the device results indroppingpowertothe
relays. The control logic will also respond by turning off the re-
lays. After four limit cycle trips the unit goes into a 1 hour soft
lockout period. If during this period the control “sees” another
limitcycle, theunitwill gointoa hardlockoutcondition. Oncein
a hard lockout state, the fan is locked on and the heaters are
disabled. Only a power cycle will clear the state.
During the soft lockout period, the fan responds to thermostat
input but the heaters are enabled. This is to sense a failed
heater relay. The limit cycle count is reset at the start of a heat
request. If the limit remains open for period of 80 seconds or
more, the control is immediately put into a hard lockout condi-
tion. Only a power cycle will clear this state.
