Frequently Asked Questions - PAC22 Series 2 Andrews

How do I install the PAC22 Series 2 air conditioner?

Place the unit near a window and connect the exhaust hose to the window kit. Adjust the window slider to fit your window opening. Plug the unit into a grounded power socket and turn it on.

Why is the air conditioner not cooling properly?

Check if the air filter is dirty; clean it if necessary. Ensure the exhaust hose is not blocked or kinked. Also verify that the room size is within the unit's cooling capacity (12000 BTU).

How often should I clean the filter?

Clean the filter every two weeks during heavy use. Remove the filter, wash it with lukewarm water and mild detergent, let it dry completely before reinstalling.

Can I use the air conditioner without the exhaust hose?

No, the exhaust hose must be connected to expel hot air outside. Operating without it will reduce cooling efficiency and may damage the unit.

What does the 'Sleep Mode' do?

Sleep Mode gradually increases the set temperature by 1-2°C over a few hours to provide comfortable sleeping conditions while saving energy.

How do I drain the water tank?

When the water tank is full, the unit will beep and stop cooling. Locate the drain plug at the back, place a container under it, and remove the plug to drain. Alternatively, attach a garden hose for continuous drainage.

Is the air conditioner suitable for large rooms?

The PAC22 Series 2 is designed for medium-sized rooms up to approximately 25-30 m² (270-320 sq ft). Larger rooms may require additional cooling.

How do I reset the timer?

Press the Timer button on the remote or control panel until the timer indicator flashes. Use the + and - buttons to set the desired time, then press Timer again to confirm.

What safety features does this unit have?

It includes overheat protection that shuts off the compressor if it gets too hot, auto restart after power failure, and a child lock to prevent unintended operation.

Where can I find replacement parts?

Replacement parts (filters, remote control, exhaust hose) are available through the Andrews website or authorized service centers. Contact customer support for specific part numbers.

Operating Instructions - PAC22 Series 2

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 the evaporator coil and possible component damage.

To access the filter, 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 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 re-settable. Necessary access is provided either via the lower front panel or through the control console. A pencil or screwdriver with gentle pressure on the knob behind is all that is required to re-set.

HOWEVER, DO NOT ATTEMPT TO RE-SET WITHOUT FIRST DISCOVERING WHY THE TRIP OCCURRED IN THE FIRST PLACE

Installation

USE THE CHAINS PROVIDED TO SUPPORT THE HEAT EXCHANGER - IT WOULD BE HIGHLY DANGEROUS TO SUPPORT THE HEAT EXCHANGER BY MEANS OF THE FLEXIBLE LINES ALONE.

In operation the room unit is constantly condensing water vapour out of the atmosphere (reducing relative humidity). This water has to be drained away, An automatic condensate pump is fitted inside the room unit. The flexible hose outlet from the condensate pump runs to the outside, inside the flexible sheath and the condensate is deposited in the base of 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 possibility of kinking or unnecessary restrictions to the flow of water inside. Also, remember that plastic and rubber becomes much more flexible when warm and. as a result, much more susceptible to distortion.

Machine Link-Up

Ensure the mains supply lead to the room unit is disconnected, A 5m (extendable to 30m) 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 3 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.

Room 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 (fig. 2) is located to the rear of the room unit and can be accessed by removing the two screws holding the security plate over the filter tank cap. Ensure the machine is running in cooling mode before removing the header tank cap, and as with all the 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 -20C/-5F.

This unit MUST be transported and operated in the upright position at all times.

Electrical Supply

WARNING! As standard this unit requires a 13 amp fused electrical supply rated at 230 volts. -1N, 50Hz.

The unit will operate from a standard 13A wall socket. The size of any extension cable that may be 2-5mm ² minimum up to a maximum length of 10 metres. For longer lengths 4mm ² cable must be used. If the cable is on a 'cable drum' then ensure that it is completely unwound; serious complications will occur otherwise.

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 and all interconnecting pipes and electrics are enclosed in a flexible plastic sheath. 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.

Airflow

The angled air outlets at the top of the 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.

Siting

Ideally, the room unit should be positioned equidistant along he shortest wall in the room blowing down the length of the room. Of 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 satisfactory applying portable air conditioners. If in doubt seek the advice of your supplier.

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 or may be hung in the upright position, from a window-sill, balcony etc. (see fig. 1).

Operating Instructions - PAC22 Series 2

Series 2

1. Revolve thermostat knob fully clock to the number "8" position.
2. Plug in the room unit mains cable, and switch on electricity, red mains light will illuminate.
3. Select fan only. With the mode switch. The fan will start.
4. Select "fan speed", with the fan speed switch. High or low depending on air velocity required
5. Select "cooling" with the mode switch, and revolve the thermostat knob fully anti-clockwise to the number "1" position. The external heat exchanger fan and the water pump in the room unit will start. After a delay of 4 mins the green "cooling" light will illuminate and the machine will proceed to cool the air.

Monitor the room temperature and when it has reduced to the desired level. Very slowly revolve the thermostat knob back, clockwise, until the green “cooling” light goes out. The room unit will now control the room temperature cooling automatically at this setting.
