Frequently Asked Questions - Zephyr ET Andrews

What electrical supply does the Andrews Zephyr ET air conditioner require?

The unit requires a 230 V, 13 A, 50 Hz single-phase electrical supply and plugs into a standard BS1363 domestic socket.

How do I start the cooling function?

Turn the thermostat knob fully clockwise to '8', plug in and switch on. Select 'Fan Only' mode, then 'Cooling' mode. Turn the thermostat knob fully anti-clockwise to '1'. After a 10-minute delay, the green cooling light illuminates and cooling begins.

How do I set the desired room temperature?

Monitor the room temperature. When it reaches your desired level, slowly turn the thermostat knob clockwise until the green cooling light goes out. The unit will then automatically maintain that temperature.

How often should I clean the air filter?

The filter should be cleaned at least every 2 months. More frequent cleaning may be needed in dusty environments.

How do I clean the air filter?

Access the filter by opening the hinged lower panel or removing the return air grille. Wash the filter in warm soapy water, rinse, and shake dry before replacing.

What should I do if the unit does not cool?

Check if the amber 'ATTENTION' or 'CONTAINER FULL' light is illuminated. If 'CONTAINER FULL', empty the condensate bottle. For 'ATTENTION', ensure the condensate pump is working and tubes are not kinked or frozen.

Can I use an extension cord?

Yes, but the extension cord must be of 2.5 mm² minimum for lengths up to 10 meters, and 4 mm² for longer runs. It must be fully uncoiled and of suitable rating.

How do I empty the condensate container?

Pull forward the lower front panel to access the container. Empty it and carefully replace, ensuring the drain pipe is fitted into the container.

What safety precautions should I follow?

Keep children and animals away, never operate if tired or under influence, keep vents clear, unplug after use, and inspect cables for damage. Use a RCD for additional safety.

What is the expected lifespan of the air filter?

The filter typically lasts about 12 months and should be replaced annually. Spare parts are available from your supplier.

Operating Instructions & Safety Guide

ANDREWS

AIR CONDITIONING

General Safety

• Keep children and animals away from air conditioning units. Never leave them alone in a room where the units in use.
  This equipment should only be used by a competent person 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.
• Keep the Air Conditioning vents clear of all obstructions.
  Never put anything on top of the unit or block the air outlets.
  Make sure equipment is switched off and unplugged after use
  Never leave switched on or unattended.
  Do not use the unit where sunlight is shining directly onto it.
  Check condition of equipment before use. If unit is showing signs of damage contact your supplier immediately.

Electrical Safety

This unit requires a 230 volt electrical supply. It plugs into a standard BS1363 domestic socket.
Always inspect plugs and leads for damage before plugging into the supply - DO NOT USE IF ANY DAMAGE IS FOUND
Ensure cables are run as not to cause a hazard.
If an extension lead is used, ensure it is of the correct standard, and fully uncoiled when being used.
Do not lay electrical cables in wet / damp areas.
Do not move equipment whilst operating.
Do not pull equipment by its cable.
It is recommended that electrical equipment is used via a suitable RCD.

WARNING!

As standard this unit requires a 13 amp fused electrical supply rated at 230v 1ph 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 4mm2 cable must be used. If the cable is on a 'cable drum' then ensure that it is completely unwound; serious complications will occur otherwise.

Air Cooled Units

The system comprises, a room unit fitted with either a fixed or flexible ducting system as specified by the customer. Condensate is collected, either in the units internal tank and emptied by the user or pumped using an optional condensate disposal unit (fig. 1).

Air Flow

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. An alternative top panel with twin 7" ducts is available.

Siting of Zephyr

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 t 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.

Exhaust Tubes Air Cooled Unit

The exhaust tube(s) must carry the air to an area external to that being cooled, preferably in the outside atmosphere (fig. 1).

Operating Instructions - Zephyr ET

Operation Instructions

The control panel on the room unit is illustrated below

Revolve thermostat knob fully CLOCKWISE to the number '8' position
Plug in the room unit mains cable, and switch on the electricity, red mains light will illuminate.
Select 'Fan Only' with the mode switch. The fan will start.
Select 'Fan Speed' with the fan speed switch, high or low depending on air velocity required.
Select 'Cooling' with the mode switch, and revolve the thermostat knob fully ANTI-CLOCKWISE to he number '1' position. 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.

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.

Accessing the Filter

On machines fitted with a hinged lower panel, open panel. The filter is located on front of the evaporator. A second filter is fitted to the rear panel on all air cooled machines.

On machines without a hinged front panel, to access the filter, lift out the return air grille on the front face of the unit. 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 (see fig. 4 / 5).

Problem Likely Cause Solution
No cooling Amber 'ATTENTION' light illuminated. High level condensate trip.		Condensate pump not reducing water level Kink in condensate tube between room unit and external heat exchanger? Leak inside room unit. Pump filter inside room unit blocked. Condensate tube frozen.
No cooling Amber 'ATTENTION' light illuminated. Bottle fitted switch trip.		On machines without a removable bottle, ensure link fitted to terminal block. On machines with , ensure bottle fitted correctly.
No cooling Amber 'CONTAINER FULL' light illuminated. High level condensate trip.		On machines without a removable bottle, as above. On machines with a bottle, remove container and replace correctly. To empty the condensate bottle, pull forward the lower front panel, (Fig 2).The front cover will come forward, giving access to the container, (Fig 3).Empty the container, and carefully replace.Ensure the drain pipe is fitted into the container.
