SUMMARY The idea behind the unit is to provide a localized supply of cool air. The unit will greatly enhance your personal comfort whether at a work station or even in your favorite chair. Four (4) casters enable you to move the unit easily from room to room. It cools and dries the air at the same time so that you can stay comfortable even when it is humid or rainy outside. Also your furnishings and fabrics are kept in good condition when it is used as dehumidifier. Conventional air conditioners use large quantities of energy to cool an entire room, including walls and furniture. This unit creates a zone of cool and dry air only where it is needed. It does not waste energy cooling the surroundings. It is easy to operate. The built-in timer allows from 0.5 to 24 hours of operation, which will automatically turn the unit on and off. At bedtime, sleep function is convenient. By increasing the preset temperature by slow degrees, you can sleep more comfortable. Venting is not required. However, if the unit is to be used exclusive- ly in one space, the cooling efficiency will be enhanced by using the venting kit accessory, which is included with the unit. OPERATIONAL FEATURES

1. COOLING OPERATION / HEATING OPERATION (For TAD-

2235E): Normally, cool air / heat air (For TAD-2235E) is directed out the front louvers by the circulation fan.

2. AUTOMATIC OPERATION:

Once the desired function has been set, it is memorized as long as it remains connected to the wall outlet. In the event of a power failure, the desired function must be re-entered when power is restored.

The unit will turn on and off after the designated period of time (0.5, 1, 1.5, ....24 hours).

5. AUTOMATIC SHUT-OFF MECHANISM WHEN THE DRAIN

TANK IS FULL: When the chassis is full with water, the unit will be automati- cally shut off. The buzzer will give out 8 seconds and “H8” is displayed on the remote controller.

A pre-filter protects the unit from dust.

5. Operate the unit in Fan mode to dry the interior of the unit.

• Remove the drain water from the tank once a week.

• Cooling or drying operation, the condensation water will be drained to the chassis and spattered by water-striking motor. As the temperature of condenser is high, most of the condensation water will be evaporated and drained to outdoor. So usually, only a little condensation water will be accumulated inside the chassis and you do not need to discharge the water frequently.

• When the chassis is full with water, the buzzer will give out 8 sounds and “H8” is displayed to remind user to dis- charge water:

5. CONTINUOUS DRAINAGE

There are 2 ways to remove collected water:

1. DRAINAGE FROM THE BOTTOM HOLE (Fig. I)

NOTE: When using the continuous drainage option from the bot- tom hole, install drainage pipe before using, otherwise poor drainage will affect normal operation of the unit. Prepare the below accessory. I1 Drainage hose I2 Hose band I3 Screw I4 Drainage hose clip I5 Rubber plug

2. Fix the drainage hose clip (I4) on the right of rear side plate

near drainage port with a screw (I3). (Fig. I7)

3. Put the drainage hose (I1) into drainage port and screw it up,

and then bind it with hose band (I2) (Fig. I8)

4. Put the rubber plug (I5) into the other side of drainage hose, fix

it with hose band (I2) and place it into the drainage hose clip. (Fig. I9) For continuous drainage, take the drainage hose from the clip and pull out the rubber cap on the drainage hose to discharge water. (Fig. I9) NOTE:

• After finishing discharging water, put back the rubber cap onto drainage hose and then fix the hose on the clip.

After full water protection is eliminated and the compressor has been stopped for 3 minutes, the unit will resume operation.

13. Specialist’s Manual

Aptitude requirement for maintenance man(repairs should be do- ne only be specialists). a. All the work men who are engaging in the refrigeration system should bear the valid certification awarded by the authoritative organization and the qualification for dealing with the refrigera- tion system recognized by this industry. b. It can only be repaired by the method suggested by the equip- ment’s manufacturer. If it needs other technician to maintain and repair the appliance, they should be supervised by the person who bears the qualifi- cation for using the flammable refrigerant. Safety preparation work before installation The safety must be inspected before maintaining the appliances with the flammable refrigerant for reducing the flammable hazard to the lowest. Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being present while the work is being performed. Detection of flammable refrigerants Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used. Environment checking

• All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined spaces shall be avoided. The area around the work- space shall be sectioned off. Ensure that the conditions within the area have been made safe by control of flammable material.

• The area shall be checked with an appropriate refrigerant detec- tor prior to and during work, to ensure the technician is aware of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e. non-sparking, ade- quately sealed or intrinsically safe.

• No person carrying out work in relation to a refrigeration system which involves exposing any pipe work shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of in- stallation, repairing, removing and disposal, during which refrig- erant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. “No Smoking” signs shall be displayed.

• If any hot work is to be conducted on the refrigeration equip- ment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO

fire extinguisher adjacent to the charging area.

• Ensure that the area is in the open or that it is adequately venti- lated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely dis- perse any released refrigerant and preferably expel it externally into the atmosphere. Refrigeration equipment Checking Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be fol- lowed. If in doubt, consult the manufacturer’s technical department for assistance. The following checks shall be applied to installations using flam- mable refrigerants:

• The actual refrigerant charge is in accordance with the room size within which the refrigerant containing parts are installed;

• The ventilation machinery and outlets are operating adequately and are not obstructed;

• If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;

• Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;

• Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against be- ing so corroded. Electrical devices checking Repair and maintenance to electrical components shall include ini- tial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to contin- ue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the equipment so all parties are advised. Initial safety checks shall include:

• That capacitors are discharged: this shall be done in a safe man- ner to avoid possibility of sparking;

• That no live electrical components and wiring are exposed while charging, recovering or purging the system;

• That there is continuity of earth bonding. Repairs to sealed components During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation. Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected. This shall include damage to cables, excessive number of connec- tions, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.

• Ensure that the apparatus is mounted securely.

• Ensure that seals or sealing materials have not degraded to the point that they no longer serve the purpose of preventing the in- gress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specifications. NOTE : The use of silicon sealant can inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe compo

nents do not have to be isolated prior to working on them. Cabling Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans. Leak detection methods The following leak detection methods are deemed acceptable for all refrigerant systems. Electronic leak detectors may be used to detect refrigerant leaks but, in the case of flammable refrigerants, the sensitivity may not be adequate, or may need re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL8 ENGLISH of the refrigerant and shall be calibrated to the refrigerant em- ployed, and the appropriate percentage of gas (25 % maximum) is confirmed. Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work. If a leak is suspected, all naked flames shall be removed/extin- guished. If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak. For appliances containing flammable refrigerants, oxygen free nitrogen (OFN) shall then be purged through the system both be- fore and during the brazing process. Removal and evacuation When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used. However, for flammable refrigerants it is important that best prac- tice is followed since flammability is a consideration. The following procedure shall be adhered to:

• purge the circuit with inert gas;

• purge again with inert gas;

• open the circuit by cutting or brazing. The refrigerant charge shall be recovered into the correct recovery cylinders. For appliances containing flammable refrigerants, the system shall be “flushed” with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used for purging refrigerant systems. For appliances containing flammable refrigerants, flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then vent- ing to atmosphere, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the sys- tem. When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipe-work are to take place. Ensure that the outlet for the vacuum pump is not close to any ig- nition sources and that ventilation is available. Charging procedures In addition to conventional charging procedures, the following re- quirements shall be followed. – Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimise the amount of refrigerant contained in them. – Cylinders shall be kept upright. – Ensure that the refrigeration system is earthed prior to charging the system with refrigerant. – Label the system when charging is complete (if not already). – Extreme care shall be taken not to overfill the refrigeration sys- tem. Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall be leak-tested on completion of charging but pri- or to commissioning. A follow up leak test shall be carried out prior to leaving the site. Decommissioning Before carrying out this procedure, it is essential that the techni- cian is completely familiar with the equipment and all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. It is essential that electrical power is available before the task is commenced. a) Become familiar with the equipment and its operation. b) Isolate system electrically. c) Before attempting the procedure, ensure that:

• mechanical handling equipment is available, if required, for han- dling refrigerant cylinders;

• all personal protective equipment is available and being used correctly;

• the recovery process is supervised at all times by a competent person;

• recovery equipment and cylinders conform to the appropriate standards. d) Pump down refrigerant system, if possible. e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system. f) Make sure that cylinder is situated on the scales before recov- ery takes place. g) Start the recovery machine and operate in accordance with manufacturer's instructions. h) Do not overfill cylinders. (No more than 80 % volume liquid charge).

i) Do not exceed the maximum working pressure of the cylinder,

even temporarily. j) When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off. k) Recovered refrigerant shall not be charged into another refriger- ation system unless it has been cleaned and checked. Labelling Equipment shall be labelled stating that it has been de-commis- sioned and emptied of refrigerant. The label shall be dated and signed. For appliances containing flammable refrigerants, ensure that there are labels on the equipment stating the equipment con- tains flammable refrigerant. Recovery When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrig- erants are removed safely. When transferring refrigerant into cylinders, ensure that only appro- priate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge are available. All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pres- sure-relief valve and associated shut-off valves in good working or- der. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs. The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of all appropriate refrigerants including, when applicable, flammable refrigerants. In addition, a set of cali- brated weighing scales shall be available and in good working or- der. Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly main- tained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult manu- facturer if in doubt. The recovered refrigerant shall be returned to the refrigerant sup- plier in the correct recovery cylinder, and the relevant waste trans- fer note arranged. Do not mix refrigerants in recovery units and es- pecially not in cylinders. If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the com- pressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.9 ENGLISH LIMITED WARRANTY TOYOTOMI CO., LTD.
