LOCATIONS AND RECOMMENDATIONS
These units are designed for outdoor installation. For proper installation, the following recommendations must be considered.
NOTE: Unit shipped for horizontal
flow per instruction.

installation. Convert to down-

The discharge air from the condenser fans must be unrestricted for
a minimum of 3 feet above the unit.
Roof Mounting Curb (field assembled BAYCURB030A!038A
and
BAYCURB034A) or a field fabricated curb must be in place before
unit is hoisted to the roof.
Roof Mounting Curb (frame) must be installed on a flat, level
section of the roof (max. of 1/4" per foot pitch), providing a level
mounting surface for the unit. In addition, provide sufficient
height above the roof to prevent water from entering unit.
In locations where deep snows are encountered,RAiSE THE UNIT
AMINIMUM OF 12" OFFTHE ROOF, DECKOR SLAB--the chance
of the coil being blocked with snow will be reduced. The water that
occurs during the defrost has a better chance of flowing from the
vicinity of the unit.
Roof Mounting Curb used with WCC--F models is approximately
14" high. This is normally sufficient height to prevent snow blockage
and additional clearance is not necessary.

Page 6

AVOID LOCATING THE UNIT WHERE SNOWTENDS TO DRIFT.
This will reduce the times when it is necessary for the customer to
remove the snow from around the unit. MAKE CERTAIN THE
CUSTOMER KNOWS THAT SNOW ACCUMULATIONS SHOULD
BE REMOVED FROM THE SIDES OF THE UNIT FOR BEST
EFFICIENCY.
A snow drift barrier may be installed around the unit to prevent a
build up of snow on the sides of the unit. The barrier should be of
sufficient distance from the unitto prevent restriction of airflowto and
from unit.
LOCATE THE UNIT SO THAT THE WATER VAPOR THAT DISCHARGES UPWARD DURING DEFROST DOES NOT CONDENSE
ON WINDOWS AN D FOG THEM OR CAUSE ICICLES TO FORM ON
OVERHANGS.
1. Be sure the mounting curb spans structural members (trusses)
of the roof, thereby providing sufficient support for weight of the
unit, curb and duct(s) plus any accessories (factory or field
installed). See Figures 1,2, 3, 4, 5, 6, 7, 8, 9,10,11 and 12.
NOTE: If any internal accessories are to be added to the unit it should
be done at the shop if at all practical.
2. Unit should be positioned so Roof-Run-Off
directly on unit.

water does not pour

3. For "Roof Top Application," unit must be elevated above roof with
a mounting Curb or Frame.
4. Exhaust vents or other sources of contaminated air should not
be near unit air inlet if outside air is to be introduced as a makeup air or the economizer ventilation feature is to be used.
5. Check the handling facilities to insure the safety of personnel and
the unit(s).
6. CAUTION MUST BE TAKEN AT ALL TIMES TO AVOID PERSONAL INJURIES AND/OR DAMAGE TO EQUIPMENT.
7. The unit must be mounted level for proper drainage of defrost
water through the holes in the base pan.
8. Flexible duct connectors must be of a flame retardant material. All
duct work outside of the structure must be insulated and weatherproofed in accordance with local codes.
9. Roof flashing must be installed to seal the roof curb cavity and
must conform to local building codes.

11. Access and service clearances for the unit must be given careful
consideration when locating the duct entrance openings. Figures 6 and 8 provide unit dimensions.
12. All fabricated outdoor ducts should be as short as possible.
13. Be sure the hole in the structure for the ducts is large enough to
accommodate the fabricated ducts and the insulation surrounding them. (See Figure 6.)

CLEARANCES
1. The recommended clearances for single-unit installations are
illustrated in Figures 5 and 6. These minimum requirements are not
only an important consideration when determining unit placement,
but they are also essential to ensure adequate serviceability,
maximum capacity, and peak operating efficiency.
2. Any reduction of the unit clearances indicated in this illustration
may result in condenser coil starvation, or the recirculation of warm
condenser air. Actual clearances which appear to be inadequate
should be reviewed with a local sales engineer.
IMPORTANT!: To convert to downflow remove covers from
the downflow supply and return air openings and placethem
over the horizontal supply and return air openings (painted
side out) and secure with sheet metal screws.

10. Holes through exterior walls must be sealed in accordance with
local codes.

iNSTALLATiON
UNIT SUPPORT
If unit is to be roof mounted, check building codes for weight
distribution requirements. Refer to accessory roof curb mounting
instructions. Check unit nameplate for supply voltage required.
Determine if adequate electrical power is available. Refer to specification sheet.

LOCATION

AND CLEARANCES

Installation of the unit should conform to local building codes or, in
the absence of local codes, to the ANSI/NFPA No. 70-1987 National
Electrical Code or "Latest Revision." Canadian installations must
conform to CSA and local codes.
Select a location that will permit unobstructed airflow into the
condenser coil and away from the fan discharge and permit unobstructed service access into the compressor compartment. Suggested airflow clearances and service clearances are given in
Figure 5.

STARTING

THE UNIT iN THE COOLING

MODE

CAUTION: Before startingthe system on the cooling cycle, turn the
thermostat switch to OFF and close the unit disconnect switch. This
procedure energizes the compressor crankcase heater, vaporizing
any liquid refrigerant in the crankcase. This is a precaution against
foaming at startup which could damage the compressor bearings.
Allow the heater to operate a minimum of eight (8) hours.

With the compressor operating, check the line voltage at the unit.
The voltage should be within the range shown on the unit nameplate. If Iowvoltage is encountered, check the size and length of the
supply line from the main disconnect to the unit. The line may be
undersized for the length of the run.

SEQUENCE

OF OPERATION

Heat Pump -- General

Heating

Operation of the unit heating and cooling cycles is automatic when
the system is in the HEAT or COOL functions.
(The optional
automatic changeover thermostat, when in the AUTO position,
automatically changes to heat or cool with an appropriate room
temperature change.) The fan switch can be placed in the ON
position, causing continuous indoor fan operation. The fan switch
may also be placed in the AUTO position causing fan operation to
coincide with heating or cooling run cycles.

The thermostat heating switch (TSH=I) closes completing the 24 volt
circuit from terminal "R" to terminal "Y" energizing the compressor
contactor and to terminal "G" to energize the fan relay (F). When
(TSH-1) closes, the heat anticipator (HA)is energized. (The heat
anticipator provides heat to the thermostat bimetal during operation
of the heat pump or resistance heat cycle. The switchover valve (SO)
is not energized due to the voltage drop across the heat anticipator.)
The MS-1 and MS=2 contacts close simultaneously and energize the
compressor,and the outdoor fan motor. At the same time, the F=I
contacts close and energize the indoor fan motor and the F=2
contacts provide a fan interlock for the heater control circuit

Cooling Mode
With the disconnect in the ON position, current is supplied to the
sump heater and control transformer.
The sump heater supplies
heat to the compressor to prevent liquid refrigerant from accumulating in the compressor during the off cycle.
The thermostat temperature switch (TSC-1) closes completing the
24 volt circuit from terminal "R" to terminal "O" energizing the
switchover valve solenoid coil (SC). (Nothing else occurs.)
Second Stage Cooling (after a 0.7°Fto 1.5°F temperature rise): The
thermostat temperature switch (TSC=2) closes completing the 24
volt circuit from terminal "R" to terminal "Y" energizing the compressor contactor (MS) and to terminal "G" to energize the fan relay (F).
The MS-1 and MS-2 contacts close simultaneously
energizing the
compressor,and outdoor fan motor. The F=I contact closes and
energizes the indoor fan motor. When the (TSC=2) switch closes, the
cooling anticipator is bypassed.

Electronic
Defrost

Mode

Second Stage Heating (after a 0.7°F to 1.5 ° F temperature drop):
The thermostat heating switch TSH-2 closes and completes a 24 volt
circuit from terminal "R" to terminals "W" and "U" which are bussed
together and thereby energizes the blue light on the thermostat.

Emergency

Heat

Positioning the emergency resistance heat switch (RHS) in the
thermostat to the ON position will de-energize the refrigerant system
and the supplementary heat will come on through the second stage
heating contact (TSH-2) of the thermostat. Prior to this, the first
stage heating contact (TSH-1) would have closed the circuit to the
indoor blower, which will continue to run through the emergency heat
cycle and will stop when TSH-1 is satisfied and opens. A red light
indicator is visible when the switch is set to emergency heat.

Time and Temperature

Cycle

The electronic defrost board is a combination time/temperature
device. It is designed to control the removal of frost and ice from the
outdoor coil of a heat pump when coil temperatures are low.
Defrosting of the coil is initiated at a pre-selected time interval,
provided the outdoor coil is below the preset initiation temperature.
One of three time intervals (50, 70, or 90 minutes) may be chosen,
allowing the installer to adjust the time for his particular climate. In
humid and northern climates, for example, the time interval may
need to be shorter than in dry climates.
The electronic defrost board terminates the defrosting cycle when
the outdoor coil temperature rises to the preset termination temperature or after a preset defrost time has passed, regardless of
windvelocity. This helps ensurethatthe heat pump stays in defrost
only as long as is necessary to remove the frost and ice from the
outdoor coil.
OPERATION: Power to the defrost board (DFC) is provided when
the temperature sensing switch (DT) on the outdoor coil is closed.
Defrost time interval is accumulated with starts and stops of the wall
thermostat's call for heating. At the end of the chosen time interval,
assuming the temperature sensing switch is closed, a defrost cycle
starts. When the defrost cycle starts, the contacts on the defrost
board close thereby energizing the switchover valve relay (SOV)
and the electric heater contactor. A normally closed contact on the
defrost board opens the circuit to the outdoor fan motor (ODM).
The defrost cycle is terminated when the temperature sensing
switch opens or the 10 minute override interrupts the defrost period.

Defrost

On termination of the defrost cycle, the timing period is reset.

Defrost

Control

Board

SELECTIONS

TEST FEATURE:
The test feature is provided for use by the
installer or serviceman to verify that the electronic defrost board is
operating properly. To initiate a defrost cycle, the two TST pins are
shorted together until the cycle has been initiated.
All timing
functions are shortened to 11.7, 16.4, or 20.3 seconds for the 50, 70,
and 90 minute time interval settings, respectively.
After defrost
initiation, the short across the two TST pins MUST BE REMOVED
IMMEDIATELY, or the defrost period will last only 2.3 seconds.
Defrost is terminated as described in the OPERATION section.

MAINTENANCE
ROUTINE MAINTENANCE BY OWNER
You can do some of the periodic maintenance functions for
your WCC-F unit yourself; this includes replacing the disposable or cleaning the permanent air filters, cleaning the unit
cabinet, clearing the condenser coil, and conducting a general
unit inspection on a regular basis.
Be su re to inspect them at least once each month when the
system is in constant operation. (In new homes, check the
filters every week for the first four (4) weeks.)
If you have disposable-type filters, replace them with new
filters of the same type and size. Do not attempt to clean
disposable filters.
Permanent-type filters can be cleaned by washing them with a
mild detergent and water. Make sure that the filters are
thoroughly dry before re-installing them in the unit (or duct
system).
NOTE: It may be necessary to replace permanent filters
annually if washing fails to clean the filter or if the filter shows
signs of deterioration. Be sure to use the same type and size
as was originally installed.
CONDENSER COIL
Unfiltered air circulates through the unit's condenser coil and
can cause the coil's surface to become clogged with dust, dirt,
etc. To clean the coil, vertically (i.e., with the fins) stroke the
coil surface with a soft-bristled brush.

MAINTENANCE PERFORMED BY SERVICEMAN==
HEATING SEASON
Complete the unit inspections and service routines
below at the beginning of each heating season.
