Frequently Asked Questions - PAC60 Andrews

What are the electrical requirements for the Andrews PAC60?

The PAC60 requires a 400V, 3-phase, 50Hz supply with a 25A fused circuit. It connects via a 32A 3-phase wall socket. Ensure compliance with IEE regulations.

How do I clean the air filter?

Remove the return air grille on the front of the room unit. Take out the foam filter and wash it in warm soapy water. Rinse, shake dry, and reinsert. Clean at least every 2 months.

The unit is not cooling, what should I check?

Check if the green 'Cooling' light is on. If off, lower the thermostat set point. If the red 'High Pressure' fault light is on, press the '+' button to reset and check for water shortage, blocked coil, or frozen water. If the red 'Low Pressure' fault light is on, press the '-' button and check for blocked filter or ice on evaporator.

How do I adjust the thermostat set point?

Press and release the P button once. The set point value (e.g., 28) will flash. Use the ▲ or ▼ keys to change, then press P again to save. Cooling starts at 1°C above the new set point.

What type of antifreeze should I use?

Use a mixture of one part antifreeze to two parts water (33% antifreeze). This prevents freezing down to -20°C. Do not apply mains water pressure.

How do I reset the high pressure fault?

Press the + button on the control panel to reset the high pressure switch. Before resetting, identify and rectify the cause (e.g., water shortage, blocked coil, frozen water).

What does error code E1 or -E1 mean on the display?

Error E1 or -E1 indicates a probe interrupt or short circuit. Verify the correct connection between the probe and thermostat, then check the probe function.

Can I use an extension cord with the PAC60?

No, do not use extension cords. The unit requires a dedicated 25A fused circuit. Ensure the mains supply is adequate and the plug is properly connected.

How do I connect the room unit to the heat exchanger?

Use the supplied 15m line set. Connect the water pipes via quick-connect couplers (push-on with locking ring). Connect the 5-pin electrical coupler (push-fit with screw lock ring, hand tight) and the 6mm condensate drain pipe. Ensure the room unit is unplugged during connection.

How often should I perform maintenance on the PAC60?

Clean the air filter at least every 2 months. Check water/antifreeze level and top up if needed. Inspect condensate tube for kinks. Have a competent electrician check electrical connections annually.

Air conditioners should only be used in the manner and purpose for which they were intended and in accordance with the recommendations detailed in this leaflet. Our air conditioners have been designed, produced and inspected with safety in mind, but there are certain basic precautions which should be taken by the user and in particular attention is drawn to the safety precaution in this leaflet.

It is imperative, therefore, that all persons who may make use of our equipment have all the information and instructions they require to ensure that they are fully aware of any hazards, and that they know both the purpose and the correct manner of the use of the equipment.

GENERAL SAFETY

This equipment should only be operated by a competent adult who has read and understood these instructions.

Never operate this equipment if you are ill, feeling tired or under the influence of alcohol or drugs.

Never put anything on top of the unit or block the air inlets or outlets.

Make sure equipment is switched off and unplugged after use.

Check condition of equipment before use. If unit is showing signs of damage contact your supplier immediately.

*The user must not undertake any service or repair of equipment.

*Ensure debris or detritus cannot be drawn into the outdoor unit fan's airflow.

ANY DOUBT CONCERNING APPLICATION / INSTALLATION CONSULT YOUR SUPPLIER.

2) INSTALLATION.

ELECTRICAL SUPPLY

All electrical installations must comply with current IEE regulations.

As standard, this unit requires a 25 Amp fused electrical supply rated at 400Volts, \~3N, 50Hz.

The unit will operate from a 32A, 3 phase wall socket.

Do not run umbilical in lying water.

Do not disconnect plugs until the mains supply has been isolated.

Ensure floor surface is adequate for the weight.

Ensure the outdoor unit (hex) is safely located on a level surface with the wheels locked, away from possible unauthorised interference.

3) SYSTEM DESCRIPTION.

The system comprises a room unit cooling section, an external heat exchanger and the two are interconnected by means of a flow and return water pipe and an electrical supply to the heat exchanger fan. The room unit is fitted with an automatic condensate disposal pump which discharges the condensate via a small plastic pipe into the base of the external heat exchanger. This pipe and all interconnecting pipes and electrics are secured together. In addition, both ends of each pipe are fitted with "quick connect" couplings that open on coupling but reseal to become water tight on disconnect.

4) AIR FLOW

The angled air outlets at the top of the standard room unit are fitted with air grilles that allow the angle of air outlet to be adjusted vertically and horizontally and, in conjunction with the fan speed control switch, the air velocity and direction can be carefully set up to obtain maximum coverage of the area being cooled without causing drafts. Care should be taken to avoid outlet air being obstructed as this will cause the air to "eddy" around the unit resulting in recirculation and short/inaccurate cycling of the machine. Ideally, cold air should be directed to create a "blanket" all across the ceiling area allowing natural convection to drop the air over the whole area at very low velocity.

5) SITING

ROOM UNIT.

Ideally, the room unit should be positioned equidistant along the shortest wall in the room blowing down the length of the room. If there is more than one unit in the same area, then they would normally be positioned side by side, and equidistant along the long wall, all pointing in the same direction. Sometimes it may be necessary to position units around the perimeter of an area but, in this case, great care should be taken to avoid one unit blowing cold air straight into another which will adversely affect the machine operation. Good and correct air flow is, perhaps, the single most important aspect of satisfactorily applying portable air conditioners. If in doubt seek the advice of your supplier.

HEAT EXCHANGER

The heat exchanger must stand external to the area being cooled and, preferably, in the outside atmosphere. It can stand freely on a flat surface. The castor wheels should be locked to prevent the heat exchanger from moving.

6)CONDENSATE. PAC60BX

In operation, the room unit is constantly condensing water vapour out of the atmosphere (reducing relative humidity). This water has to be drained away. Two automatic condensate pumps are fitted inside the PAC60BX room unit. The flexible hose outlet from the condensate pumps runs to the outside inside the cable bundle. The condensate is deposited in the base of the heat exchanger, considerable re-evaporation of this water takes place on the warm air stream passing through and around the heat exchanger, but please remember that there will also be a degree of dripping through the base of the heat exchanger.

HAVE GREAT REGARD FOR THIS CHARACTERISTIC WHEN POSITIONING THE EXTERNAL HEAT EXCHANGER.

The flexible water pipes should be routed so as to avoid any unnecessary restrictions to the flow of water inside.

7) MACHINE LINK-UP FOR PAC60BX/

Ensure the mains supply lead to the room unit is disconnected. A 15m line set to connect all services between the room unit and the external heat exchanger will have been supplied. The water pipe connections are by means of "quick connect couplers". These are simple 'push-on' connectors which, when disconnected (after pulling back sprung loaded locking ring), re-seal the water system on either side. The complete system will have been filled with the necessary amount of water/antifreeze prior to its arrival on site. A water proof 5 pin quick connect electrical coupler (push fit with screw lock ring, hand tight only), and condensate drain pipe coupler 6mm clear polythene (push fit), should also be connected. Having made the couplings, the system is operational immediately.

PAC CONNECTIONS

HEAT EXCHANGER CONNECTIONS

8) WATER LEVELS

The water system in the room unit will be to the correct level when delivered.

However if for some reason the level has fallen, antifreeze (33%) and water will have to be added. The header tank filler and level indication is located in the external heat exchanger.

Ensure the indoor unit is running in

cooling mode before removing the header tank cap, and as with all pressure caps, remove slowly. It is recommended that a mixture, by volume, of one part antifreeze to two parts water is utilised, this will prevent freezing down to an external temperature of -20^/-5^ .

DO NOT APPLY MAINS WATER PRESSURE TO THE SYSTEM

Press P button once and release. Set Point and set point value (28) will be displayed alternately.

Press the ▲ or ▼ key to change the value of the set point. Once the desired value is displayed press P again to memorise the value. Cooling starts at 1°C above the new set point value and stops at the set point.

After a delay of 5 to 10 minutes the amber "Cooling" light will illuminate and the machine will proceed to cool the air.

FIG.3 CONSOLE LABEL/ MARKING

11) ROUTINE MAINTENANCE

The air filter must be kept clean, never allow to become choked with dust or dirt. If allowed to do so, the performance of the unit will become impaired, resulting in loss of air flow, freezing up of the evaporator coil and possible component damage.

PAC60BX Lift out the return air grille on the front face of the unit, Fig 4. On refitting the filter ensure that it is correctly positioned covering the whole rear face of the grille. The filter (see Fig. 4) can be washed in warm, soapy water, rinsed and shaken dry before replacement. Frequency of cleaning depends upon application and can only be determined by the user. However, you should never allow more than two months to elapse between cleaning. The probable life of the filter will be about one year and spares are available from the supplier of the unit itself. Failure to have filter fitted during operation will cause serious damage.

The refrigeration circuit inside the room unit is fitted with a HIGH and a LOW pressure sensing switch. They are both manually resettable. A pencil or screwdriver with gentle pressure on the knob behind is all that is required to re-set.

Necessary access is provided via the control console of the PAC60BX.

HOWEVER, DO NOT ATTEMPT TO RESET WITHOUT FIRST DISCOVERING WHY THE TRIP OCCURRED IN THE FIRST PLACE.
