Frequently Asked Questions - PAC15 Andrews

How do I install the Andrews PAC15 air conditioner?

Installation involves placing the unit near a window, attaching the exhaust hose, and sealing the gap with the provided window kit. Secure the unit and ensure it is on a level surface. Full details are in the installation manual.

How often should I clean the air filter?

Clean the air filter every 2 weeks of use to maintain efficiency. Remove the filter, vacuum or wash with mild soap and water, dry completely before reinstalling.

What does error code E1 mean?

Error code E1 indicates a room temperature sensor malfunction. Unplug the unit for 10 minutes, then restart. If still persists, contact customer support.

Can I use the PAC15 in a room without a window?

No, the unit requires venting to the outside via the exhaust hose. It must be connected to a window or wall opening to expel hot air.

How do I use the remote control?

Insert two AAA batteries (not included), point the remote at the unit's receiver, and press the power button. Use mode, temp, and fan buttons to adjust settings.

What is the recommended room size for this air conditioner?

The PAC15 is suitable for rooms up to 350 sq. ft. (32.5 m²) with standard ceiling height.

Why is the unit not cooling?

Check that the unit is set to cool mode, the temperature is set lower than room temp, the filter is clean, and the exhaust hose is not blocked. Also ensure all windows and doors are closed.

How do I drain the water?

In high humidity, the unit collects water which is typically evaporated. If needed, locate the drain plug at the back, place a container, and remove the plug to drain manually.

Can I use an extension cord?

No, do not use an extension cord or power strip. Plug the unit directly into a grounded wall outlet rated for the voltage.

Where can I find spare parts?

Contact Andrews customer service or visit their official website for genuine replacement filters and remote controls.

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

Operating Instructions - PAC15

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.

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 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. The approximate total volume of both the available systems, large or small room unit with external heat exchanger and lines is as follows.

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 2-5mm2 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).

1. Revolve thermostat knob fully
   CLOCKWISE to the number '8' position
2. Plug in the room unit mains cable, and switch on the 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 he number '1' position. If fitted the external heat exchanger fan and the water pump in the room unit will start. After a delay of 10 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.
