Pre-installation Checklist
Jobsite Inspection
Each unit has been inspected, tested and operated at the factory by pro­duction and quality associates prior to being crated for safe transit. How­ever, rough handling or accidents can occur resulting in damaged equipment being delivered. Always perform the following checks before accepting a unit:
1. Do not sign the bill of lading
accepting the unit(s) until inspection has been com­pleted. Check for damage
promptly after the unit(s) are unloaded. Once the bill of lading is signed at the jobsite, the unit(s) are now the property of the SOLD TO party and future freight claims MAY NOT be accepted by the freight company.
2. Check the unit model numbers
on the bill of lading against those ordered and received to assure equipment is AS ORDERED.
3. Check to assure that the refrig-
erant charge has been retained during shipment by use of gauges. Schrader taps are
located and labeled internal to the cabinet. (See Figure 1).
Jobsite Storage
This unit is intended for indoor use only. To protect the unit from damage due to the elements, and to prevent possible IAQ contaminant sources from growing, the unit should be stored indoors. If indoor storage is not possible, the following provisions for outdoor storage must be met.
1. Place the unit(s) on a dry sur-
face or raise above the ground to assure adequate air circula­tion beneath the unit. This is to
assure that no portion of the unit contacts standing water at any time.
2. Cover the unit(s) with a water proof tarp to protect them from the elements.
3. Make provisions for continu­ous venting of the covered units to prevent moisture from standing on the unit(s) sur­faces. Wet interior unit insulation
can become an amplification site for microbial growth (mold) which

has been determined to be a cause of odors and serious health related indoor air quality problems.
4. Store units in the normal UP orientation. Storing units in this
manner maintains oil in the com­pressor.
5. Units may be stacked two high.
Important!
Equipment is shipped FOB (Free on Board) at the manufacturer. There­fore, freight claims for damages against the carrier must be initiated by the receiver.

Installation Instructions
5 6
Wall Flange
After removing chassis from the subbase, install the wall flange assembly to the desired wall with the use of four #10-field provided screws. The wall flange as­sembly includes four, 1/4-inch in diameter clearance holes.
Mounting of Disconnect
(receptical box-OPTION)
Mounting of the receptical box should be made prior to piping and electrical hook-up. This factory discon­nect option is designed to fit inside the end pocket. Mount the receptical box 2-inches above the top of the subbase with four, #8-field supplied screws.
7
Mounting of Disconnect
(circuit breaker-OPTION)
Mounting of the circuit breaker/receptical box should be made prior to piping and electrical hook-up. This factory disconnect option is designed to fit inside the end pocket. Mount the electrical box flush with the subbase with four, #8-field supplied screws.
20 GECA-SVX01B-EN
8
Wiring of Disconnect
(OPTION)
Power wiring to the equipment should be installed per national and local electric codes by a professional electrician.
Power wiring to the disconnect may be done at this time. See the unit’s wiring schematic for field wiring. The above schematic is for REFERENCE ONLY.

Factory Recommendation: Unit’s re-
9
Verify Fit-up
Slide the chassis onto the subbase to verify that field installed disconnects, condensate pipe, and supply/
return pipe are in the appropriate locations and will not require adustments.
ceiving the circuit breaker option should have water and condensate piping sup-
plied/returned through the bottom of
the unit OR include the ex-
tended cabinet option.
10
Water Connections
With the chassis on or off of the subbase, install the field provided water connections to the unit water-in/ out pipe. Trane recommends a 1/2-inch x 3/4-inch nominal ell to be field brazed to the factory 1/2" nomi­nal water-in/out lines.
Verify water connection angle prior to brazing of the unit water-in/out.
11
Water in/out copper size: 5/8-inch ODS or 1/2-inch nominal.
12
Field Piping
Replace Chassis
Slide chassis back into place on the subbase. To as­sure proper alignment, reinstall the two front screws (2 and 3) that attach the chassis to the subbase.
GECA-SVX01B-EN 21
Inspect the system water pipe thoroughly before con­necting the unit to the system. Water-to-refrigerant heat exchanger fouling, freezing and failure is immi­nent if the system pipe contains contaminants. All field piping must be cleaned of contaminants.
Page 22
Installation Instructions
13
Connect Supply/Return Hoses
Connect the supply and return line to the unit inlet and outlet. Flexible hoses reduce vibration from the water lines to the unit.
An isolation valve, p/t plugs and auto-flow valves are recommended to separate the closed/open loop from the mechanical device.
14
Connecting the Drain
Because the console configuration is a blow-through design, no condensate trapping is neccessary. Howev­er, it is neccessary for the condensate to run in a down­ward motion to allow gravity to properly drain the system.
The unit drain connection is 5/8-inch I.D. or 7/8" O.D. for all GECA 006-018 systems.
15
Wiring Connections
Power wiring to the equipment should be installed per national and local electric codes by a professional electrician.
Refer to STEPS 6, 7, and 8 for units that include the factory supplied disconnect.
For units containing a field pro-
vided disconnect, or, are hard wired to the unit, Trane provides pig tail
leads inside a 2 x 4 handy-box in either the right or left side end pocket. See unit wiring schematic for details.
For units containing a wall mounted ther- mostat, a low voltage (18-pole) terminal strip is provided for field installation of the thermostat. See STEP 18 for unit mounted controls.

Thermostat Location
Location of the thermostat or zone sensor is an important element of effective room control.
Areas where the thermostat/zone sensor should not be mounted include: Behind doors or corners; Near hot or cold air ducts; Near radiant heat (heat emitted from appli­ances or sun); Near concealed pipes or chimneys; On out­side walls or other non conditioned surfaces; In air-flows from adjacent zones or other units.
18
Wall Mounted Control
The thermostat hook-up to the unit is made at the unit mounted 24 V (18-pole) low voltage terminal strip. This strip is mounted on the exterior of the control box on the right side of the unit.
For units that contain left hand piping, a low voltage crossover to the 18-pole terminal strip may be neces­sary. For this configuration, run the low voltage wires behind the chassis to the right side of the console unit for termination to the terminal strip.
GECA-SVX01B-EN 23
Unit Mounted Controls
(Option)
For units with unit mounted controls, all low voltage con­nections are factory made.

Receptacle Plug
(Option)
For units with the factory provided disconnect op­tions, the receptacle plug may now be connected to the electrical outlet.

UNIT FRONT
Factory Installed Pump Kit
(Option)
All wiring to the pump kit option is factory made. NO FIELD wiring will be required. Field hook-up to the sys­tem water loop is made at the bottom of the pump box. This side of the system is usually hard piped to the pump box.
A two-position valve is installed on the pump kit. A second shut-off valve will not be required at the unit. Con­nection from the pump kit to the unit is hard piped at the factory. This hard piped assembly contains pressure/ temperature ports at the water-in/out union.
See literature number WSHPC-IN-5 (72-9006-03) for specific information related to the pump kit.

Installation Instructions
Installation of the GECA
Whether securing the GECA to a central pumping system, or a dis­tributed pumping system, Trane recommends a few accessory con­siderations to the system installa­tion.
The field supplied line volt-
1
age disconnect with circuit
breaker should be installed for branch circuit protection.
The units (2) high voltage
2
connection is located in the
right or left hand end pocket. The field connection may be made to the factory ordered disconnect, or hard wired via the factory mounted 2 x 4 handy box.
GECA-SVX01B-EN 25
The (3) low voltage con-
3
nections may be made on
the right hand side of the unit for units ordered with the wall mounted thermo­stat or sensor options. The low voltage connection is factory made if unit mount­ed controls are specified.
Because of the units blow-
4
through design, no conden­sate trapping is necessary. However, it is necessary for the condensate to run in a downward motion to allow gravity to produce a con­stant outflow.
Hose kits are used to con-
5
nect the water supply and re­turn lines to the water inlet and outlets. Trane includes various hose kit combina-
tions to better facilitate sys­tem flow balancing. These flexible hoses, reduce vibra­tion between the unit and the rigid piping system. For more information on the types of hose kits Trane rec­ommends, review the HKTA­IOM-1 manual.
The console design includes
6
a factory provided wall sleeve to facilitate installa­tion of the unit in it’s estab­lishment.
The grilles are made of a du-
7
rable plastic symetrical de­sign. The design constitutes the ability of a multi-direc­tional supply-air from the units top.

Is the high voltage power supply correct and in accordance with the nameplate ratings?
Is phasing of the unit correct per compressor rotation (scroll compressor only)?
Is the field wiring and circuit protection the correct size?
Is the low voltage control circuit wiring correct per the unit wiring diagram?
Is the piping system clean/complete and correct? (A recommendation of all system flushing of debris from
the water-to-refrigerant heat exchanger, along with air purging from the water-to-refrigerant heat exchanger be done in accordance with the Closed-Loop/Ground Source Heat Pump Systems Installation Guide).
Is vibration isolation provided? (i.e. unit isolation pad, hosekits)
Is unit serviceable? (Allow a 12-inch clearance at the unit front for serviceability).
Are the low/high-side pressure temperature caps secure and in place?
Are all the unit access panels secure and in place?
Is the thermostat in the OFF position?
Is the water flow established and circulating through all the units?
Is the duct work correctly sized, run, taped, insulated and weather proofed with proper unit arrangement?
Is the condensate line properly sized, run, and pitched?
Is the zone sensor (when used) correctly wired and in a good location?
Does the indoor blower turn freely without rubbing?
Has all work been done in accordance with applicable local and national codes?

Sequence of Operation
Initial Unit Start-up
Note:
Start-up for the TracerTM ZN510 Controller may be found in WSHP-IOP-2.
Start-up with the conventional thermostat is included below:
1.Set the thermostat to the highest position.
2.Set the thermostat system switch to COOL with the fan control to AUTO. The compres- sor should NOT run.
3.Reduce the thermostat setting until the compressor, reversing valve, solenoid valve, and loop pump are energized. Adjust water flow utilizing pressure/temperature plugs
and comparing to tables contained in specification sheet data. Water leaving the heat exchanger should be warmer than the entering water temperature (approximately 9-12 F); blower operation should be smooth; compressor and blower amps should be within data plate ratings; the suction line should be cool with no frost observed in the refriger­ant circuit.
4.Check the cooling refrigerant pressures against values in Table 1. (Page 31).
5.Turn the thermostat system switch to the OFF position. Unit should stop running and
the reversing valve should de-energize.
6.Leave unit off for approximately FIVE minutes to allow for pressure equalization.
7.Turn the thermostat to the lowest setting.
8.Set the thermostat system switch to the HEAT position.
9.Adjust the temperature setting upward until the unit is energized. Warm air should blow
from the register. A water temperature decrease of approximately 5-9 F leaving the heat exchanger should be noted. The blower and compressor operation should be smooth with no frost observed in the refrigeration circuit.
10.Check the heating refrigerant pressures against values in Table 1. (Page 31)
11.Set the thermostat to maintain the desired space temperature.
12.Instruct the owner on system operation.

Operating Pressures
GENERAL: There are many variables (airflow, air temperatures) in an air conditioning system that will affect operating refrigerant pressures and temperatures. The charts below shows approximate conditions and is based on air flow at the rated SCFM, entering air at 80.6 °F(DB), 66.2 °F(WB) in cooling, 68 °F(DB) in heating. (+)Heating data with 35 °F EWT is based on the use of an anti-freeze solution having a freezing point 20 °F lower than the minimum expected entering temperature.

Maintenance
Preventive Maintenance
Maintenance on the unit is simplified with the following preventive sugges­tions:
Filter maintenance must be per-
formed to assure proper opera­tion of the equipment. Filters should be inspected at least ev­ery three months, and replaced when it is evident they are dirty. Filter sizing includes:
Unit Size
50/60 HZ
006-018
006-018
Check the contactors and relays
within the control panel at least once a year. It is good practice to check the tightness of the various wiring connections within the control panel.
A strainer (60 mesh or greater)
must be used on an open loop system to keep debris from en­tering the unit heat exchanger and to ensure a clean system.
Filter Size

For units on well water, it is im­portant to check the cleanliness of the water-to-refrigerant heat exchanger. Should it become contaminated with dirt and scal­ing as a result of bad water, the heat exchanger will have to be back flushed and cleaned with a chemical that will remove the scale. This service should be performed by an experienced service person. It should be noted that the water quality should be checked peri­odically. (See Table 5).

Maintenance
Filter Replacement
(standard height configuration)
Filter replacement is done at the front return-air opening of the console unit. No tools are required for the replace­ment. The maintenence process is done via a 3-STEP process (See Figure 2 for filter replacement):
STEP 1: Through the return-air
opening, slide filter to the back of the con­sole unit.
STEP 2: Allow the front edge of
