1.0 GENERAL DESCRIPTION This unit is specially designed for cooling heat transfer fluid, which is used to control the temperature of tank containers. The machine is designed for uses in combination with ethylene glycol, propylene glycol, or synthetic oils where different cargoes dictate a different cooling medium. Ethylene glycol is commonly used with most chemical cargoes.
Air in the system would promote corrosion and could get trapped. This could cause noisy, inefficient operation and energy waste. The result would be loss of pump performance and corrosion of equipment. The bladder in the expansion tank has air or nitrogen on one side and system glycol on the other. The gas is pressurized to 0.8 Bar (12 psig).
The receiver is equipped with (2) sight glasses. The bottom sight glass should be filled and the ball floating during normal operation. 1.5 Heaters (if equipped) The immersion heaters are 3 phase heaters for operation on 480-volt 3 phase power. At 480 Volts, the power is 5kW.
2.0 OPERATION 2.1 Pre-starting Check The following inspection should be made before the container is loaded as part of a pre-trip inspection. All electrical power to the unit should be disconnected before inspection. 1. Visually check unit for physical damage. 2.

storage temperature is optimally very close to the temperature that freezing, crystallization, caramelizing, distillation/separation, and such non-reversible physical changes may occur. Local overcooling or overheating of the cargo at the point at which the glycol first comes in contact with the tank may be a problem with these liquids.

3.0 ELECTRICAL FUNCTIONS 3.1 General Information (Refer to Electrical Schematic) When high voltage power is being fed to the unit and CB1 is in the ON position, power will pass along L1, L2 and L3 to the compressor contactor, transformer, phase sensor and phase contactors. When the phase sensor is energized, PC1 or PC2 will be energized and allow power to the condenser fan contactor and glycol pump.
Page 16
1. Transformer 480 24V/12V (T1) The primary coil is tied into the line between the 16-Amp circuit breaker and the line starters. The secondary coil supplies 24 Volts AC for the control circuit and 12 Volts AC for the thermostat power. 3.2.4 Phase Sensor (PS) When the unit has proper voltage and frequency, it automatically selects correct phase rotation.
4.0 MICROPROCESSOR THERMOSTAT 4.1 General Information The microprocessor thermostat is an electronic solid-state device consisting of three parts: 1. The microprocessor board. 2. The cargo and glycol temperature probes 3. The display panel. All parts are mounted in the control box except the temperature probes, one of which is mounted in the bulb well in the container tank and the other in or on the glycol pipe outlet from the machine.

Pressing the C/F key one time cause the display to indicate the current temperature scale. An “F” or a “C” in the right character of the display indicates this. Pressing the C/F key twice causes the scale to change. After five seconds the display returns automatically to “normal mode”...
4.3 Temperature Sensors Each temperature sensing probe is a thermistor placed in a sealed metal tube, which is connected to a two-conductor shielded cable. The temperature signal from the probe is connected to the microprocessor board through this cable. The probes are labeled CARGO and GLYCOL but other than length, they are both the identical sensors.
4.4.3 Inputs Inputs signals to the device consist of: 1. Glycol probe temperature 2. Cargo probe temperature 3. Set point (temperature setting from display panel) 4. Safety limit setting 5. Signal from Switch 2 – up for glycol temperature/safety limit setting & down for Function test 4.4.4 Outputs Output signals from the device are by means of 8 relays.

On thermostat line 31 relay TR terminal 87a wire 31 push-on terminal can be removed (the voltage at this area is 12 VDC) This open contact will cause an external temperature fault. When you remove the wire the alarm lamp will be on.
5.0 MAINTENANCE AND SERVICE INSTRUCTION 5.1 General This section provides procedures for establishing preventative maintenance and systematic servicing schedules, which are the keys to successful operation. All service and maintenance procedures should be performed in accordance with Montreal protocol or national equivalent of the American Section 608 of the Clean Air Act. This prohibits the venting of refrigerants into the atmosphere and requires the use of refrigerant recycling and recovering equipment to be used whenever a system is opened.
CAUTION: A gauge manifold should always be used when charging unit with refrigerant. Warning: Refrigerant is heavier than air. Therefore, it settles in the lowest places and will expel air (oxygen) from a small, confined space, resulting in dizziness or suffocation to an occupant. 5.3 Checking Refrigerant Charge The receiver sight glasses are equipped with a ball which floats when the liquid level is in the sight glass or above.
a. Remove the compressor suction service valve cap and back seat the valve. This closes the charging port. Remove the cap from the port and loosely attach the suction gauge line of a manifold set. Connect the center charging line to refrigerant cylinder and tighten the connection. b.
The preferred method for finding leaks is by use of an electronic leak detector. There are several different makes available, and they all use the same method of detecting a leak through an exploring tube which will detect from large to extremely small leaks depending on the setting used on the detector.
Page 31
Venting at this point should be done at each pre-trip. Depending on the tank’s cooling system there may be additional vent points in the upper runs of the cooling system. Klinge advises that they are fitted to the tank’s pipe work but are not always notified of the details.
Page 32
It may be expedient to break the pipe work at one or two points to add the initial charge of glycol by gravity and allow the air to escape at another point. After the filling operation is complete the pump (only) should be allowed to run. Set the unit set point the same as the cargo temperature and allow the unit to operate (the compressor should not run).
Page 33
Only gas should be in the tank, if glycol comes out of this valve it indicates the bladder has failed and the gas charge has been lost. Running the unit in this condition could cause a failure. Contact Klinge Corporation or e-mail engineering@klingecorp.com for specific directions and reeferparts.com for spare parts.
Page 34
5.9.9 The Pump The pump is not self-priming and relies on the coolant as a lubricant, so should not be run dry. However, it may be run intermittently in the initial filling stage to assist in venting the system. The pump, being a moving part has a service life estimated at 4 to 5 years life of regular service in one way trade.

GLYCOL CHARGING STEPS CHECK LIST (see detail on the preceding page) INITIAL FILL 1 – Begin with the system open (no pressure). 2 – Open all vents slightly and begin adding glycol at the lowest point. The air will escape as the glycol fills.
5.10 PTI Form It is important that a Pre-Trip Inspection (PTI) be completed prior to each shipment. The TCR-104 PTI form can be found on Klinge’s website at: http://www.klingecorp.com/pti/. UNCONTROLLED WHEN PRINTED K35-TCR104-07 REV. E, JUNE 2023...
6.0 SERVICING COMPONENTS 6.1 Compressor 6.1.1 Compressor Motor Protection The compressor motor of the TCR-104 is equipped with an internal overload device. This device will break the star-point and stop the compressor if a problem arises which causes the motor to overheat. When the motor cools sufficiently, the overload will reset automatically.
Page 39
e. Back seat compressor suction service valve. Remove gauge, manifold hoses, and replace caps securely. Allow the unit to run 30 minutes before rechecking the oil level in the compressor sight glass. Check the oil immediately after the compressor has been shut off. Note: Always keep commercial oil stored in sealed containers.
3. Inspect all system controls such as expansion valve and solenoid valve. Clean or replace If necessary. Remove or replace any filter dryers previously installed in the system, and clean or replace any filters or strainers. 4. Install the recommended size remote filter drier in the suction line and an oversized filter drier in the liquid line.
6.3 Condenser Fan If a motor fan must be removed from the motor shaft for any reason, be sure that the fan dimensions for relocating the fan are used in accordance with the fan-positioning sketch. Condenser Fan Position Install assembly in the unit, but do not tighten the cap screws holding the motor to the motor mount. Extreme care must be taken to align the fan wheel and the inlet ring to be concentric and to have the fan blade extend 15/16 of an inch into the air discharge side of the inlet ring.
so suction pressure can be read. The recovery lines should come from a manifold gauge since the line will also be used to evacuate the system and perhaps add refrigerant. 2. Close the liquid line hand valve. Start the unit and pump down the system until the suction pressure stabilizes between 1 and 1.5 psig (0.1 bar).

3. Install the new element hand tight. After hand tight, turn element clockwise 60˚ (movement equal to one hex flat). 6.6.3 Expansion valve adjustment The expansion valve is set and tested at the factory before shipping. When the application or operating conditions require a different setting, the valve may be adjusted to obtain the required operating superheat.
