LOCATIONS AND RECOMMENDATIONS
These units are designed for outdoor installation. For proper installation, the following recommendations must be considered.

NOTE: If any internal accessories are to be added to the unit it
should be done at the shop if at all practical.

NOTE: Unit shipped for horizontal
downflow per instruction.

2. Unit should be positioned so Roof-Run-Off water does not pour
directly on unit.

The discharge air from the condenser fans must be unrestricted for
a minimum of 3 feet above the unit.

3. For"RoofTop Application," unit must be elevated above roof with
a mounting Curb or Frame.

Roof Mounting Curb (field assembled BAYCURB030A,038A
and
BAYCU RB033A, BAYCU RB034A) or a field fabricated curb must be
in place before unit is hoisted to the roof.

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 make-up
air or the economizer ventilation feature is to be used.

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.

5. Check the handling facilities to insure the safety of personnel and
the unit(s).

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.

7. The unit must be mounted level for proper drainage of defrost
water through the holes in the base pan.

Convert

6. CAUTION MUST BE TAKEN AT ALL TIMES TO AVOID PERSONAL INJURIES AND/OR DAMAGE TO EQUIPMENT.

LOCATIONS AND RECOMMENDATIONS
8. Flexible duct connectors must be of a flame retardant material.
All duct work outside d 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.
10. Holes through exterior walls must be sealed in accordance with
local 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 place them
over the horizontal supply and return air openings (painted
side out) and secure with sheet metal screws.

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.

PRESSURES

After the unit has operated in the cooling mode for a short period of
time, install pressure gauges on the gauge ports of the discharge
and suction line valves. Check the suction and discharge pressures
and compare them to the normal operating pressures provided in
the unit's SERWCE FACTS.
NOTE: Do not use the pressures from the unit's SERVICE FACTS
to determine the unit refrigerant charge. The correct charge is
shown on the unit nameplate. To charge the system accurately,
weigh in the charge according to the unit nameplate.

VOLTAGE
• Is the wiring properly sized and run according to the unit wiring
diagram?
• Are all the wiring connections,

including those in the unit, tight?

• Has the unit been properly grounded and fused with the recommended fuse size? See Wiring Data.

With the compressor operating, check the line voltage at the unit.
The voltage should be within the range shown on the unit nameplate. If tow voltage 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.

COOLING

SHUT DOWN

• Is the thermostat level, correctly wired, welt located, and set for
the proper heat anticipation?

Place the system selector in the OFF position or reset thermostat at
a setting above room temperature.

• Have the air conditioning systems been checked at the service
ports for charge and leak tested if necessary?

Do not de-energize the main power disconnect except when unit is
to be serviced. Power is required to keep the heat pump compressor warm and boil off refrigerant in the compressor.

• Do the condenser fan and indoor blower turn free without rubbing,
and are they tight on the shafts?

STARTING

• Has the indoor blower speed been determined and the proper
speed been set? See the Unit Wiring Diagram.
• Has all work been done in accordance with applicable local and
national codes?

STARTING

THE UNIT IN THE COOLING

MODE

CAUTION: Before starting the 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 start-up which could damage the compressor bearings.
Allow the heater to operate a minimum of eight (8) hours.
NOTE: See the section on "Sequence of Operation" for a description of the cooling operating sequence.
To start the unit in the cooling mode, set the thermostat system
switch to COOL and move the thermostat COOL indicator to a
setting below room temperature.
The condenser (outdoor) fan
motor compressor and evaporator (indoor) fan motor will operate
automatically.

SEQUENCE OF OPERATION
COOLING

GENERAL
Operation of the system cooling (and optional heating) cycles is
controlled by the position of the system switch on the room thermostat. Once the system switch is placed in either the HEAT OR
COOL position, unit operation is automatic. The optional automatic
changeover thermostat, when in the AUTO position, automatically
changes to heat or cool with sufficient room temperature change.

SWITCH SEI-rlNGS

With the unit disconnect closed, voltage is supplied to the unit
control transformer and the crankcase heater (if provided). On
single phase units, the crankcase heater is optionally field installed.

comfort, quietness, and potential energy savings. The graph
below shows the ramping process.

On a call for mechanical cooling, the indoor fan "G" and the
compressor circuit "YI" are energized. The indoor fan circuit "G"
starts with power from the control transformer and then energizes
the fan relay coil iF). This closes the fan relay iF) contacts and the

MAINTENANCE
ROUTINE

MAINTENANCE

BY OWNER

You can do some of the periodic maintenance functions for your
TCY-G unit yourself; this includes replacing the disposable or
cleaning the permanent air fitters, cleaning the unit cabinet, clearing
the condenser coil, and conducting a general unit inspection on a
regular basis,
Be sure to inspect them at Neast 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 reinstalling 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.
Be sure to keep all vegetation away from the condenser coil area.
