Installation

Location consideration

Sitting (Room unit)

Good and correct air flow is, perhaps, the single most important aspect of satisfactory use of portable air conditioners. Some examples of how to place the room unit in the most common situations are illustrated in the table below. If in doubt seek the advice of your supplier.

Installation Description Illustration options
one unit Ideally the ACT 7 room unit should be posi- tioned in the middle of the shortest wall in the room blowing down the length of the room.	x x
two units If there is more than one ACT 7 in the same area, then they would normally be posi- tioned side by side, and equally spaced along the long wall, all pointing in the same direction.	x x x
Around the perimeter	Sometimes it may be necessary to position units around the pe- rimeter of an area but, in this case, great care should be taken to avoid one unit blow- ing cold air straight into another which will adversely affect oper-a- tion.	x x x x

NOTICE

Also be aware of the following:

• the room unit has to be sited on firm level ground.
• the room unit has to be located away from any possible unauthorised interference.
• Condensation on the outside of the room unit may appear, when the room unit operates at low indoor temperatures as e.g. 10^ and high relative humidity (80%) at the same time. If operated under these conditions the units side plate should be wiped off regularly in order to avoid water on the floor.

Siting (Heat exchanger)

NOTICE

The heat exchanger must be sited external to the area being cooled and, preferably outside.

Consider especially the potential of dripping water when positioning the external heat exchanger and find a location, where debris can't get into the air flow of the heat exchanger.

a. The heat exchanger can stand freely on a flat surface or

b. It may be hung, in the upright position, from a window-sill or balcony. Use the chains provided to support the heat exchanger.

NB: When the heat exchanger is hanging, it must be fixed with a suitable hook in the wall.

Handling and set-up

Handling

Follow these instructions when handling the room unit:

CAUTION

Risk of plate deformation, damaging unit and human injuries

• Do NOT lift the room unit at the handle
• Use handle ONLY to push and drag the room unit
• Use a ramp to get the ACT 7 unit over a curb or alike.

CAUTION

Risk of damaging the cooling circuit when laying down the room unit

Oil from the compressor can get inside and damage the cooling circuit, if the unit is laid down.

• Do NOT lay the room unit down
• Always transport the room unit in an upright position

Precautions

CAUTION

Avoid getting the water/glycol mixture on your skin and clothes

The water/glycol mixture contains anticorrosive substances, which is noxious and can lead to skin irritation. The substance can be difficult to remove from clothes.

• Use gloves for connecting and disconnecting the interconnecting line.
• If the glycol/water mixture is spilled on your skin, wash thoroughly with water and soap.
• Wear work clothes while connecting and disconnecting the ACT 7.

Check the fluid level

Check always the fluid level of the ACT 7 room unit before starting up the unit.

Look through the inspection window (use a flashlight, if necessary) and check, if the fluid level is between MIN and MAX level. Top up the fluid, if the level is below MIN.

Follow the steps below, if you need to fill up the fluid level.

step Action Illustration

1 Ensure the ACT 7 is running in cooling mode, before removing the filler cap.
2 Loosen the screws and remove the security plate of the filler cap.

3 Slowly remove the filler cap

4 Top up the tank with the correct anti-freeze (33%) and water mixture until the fluid level is between min. and max. level (check the level through the inspection window).

Be aware not to mix different types of antifreeze, in order to protect the system properly.

(Original specification is ethylene glycol based antifreeze, containing rust/corrosion inhibitors, suitable for aluminium systems, 33% giving protection to -20^ . This specification will protect the entire glycol/water circuit down to -16^(-5^) .)

5 Mount the cap and security plate again.

Connecting room unit to heat exchanger

Step Description Illustration

1 Use the interconnecting line (5-30m) to connect the ACT 7 room unit to the heat exchanger.

NB: The interconnecting line should be routed carefully to avoid any possibility of kinking or unnecessary restrictions to the flow of water. The line will be more likely to kink when warm.

2 Connect the condensate drain to the ACT 7 room unit.

3 Connect the condensate drain to the heat exchanger by pushing the clear hose ends into the grey connector.

4 Connect the pipes to the a. heat exchanger and b. room unit

Pull the coupling of the female pipe adapter back in order to connect the pipes.

Be prepared with an old cloth or alike to wipe the water/glycol mixture up, since it will spill a bit, when the pipes are connected.

5 a. Connect the heat exchanger power cord to the ACT 7 room unit using the socket provided. b. Push the locking ring towards the machine. c. Turn locking ring clockwise to lock the connection. Repeat a + b + c when connecting the power cord to the heat exchanger.

Electrical supply

Plug the room unit into a power socket.

• As standard the ACT 7 requires a fused electrical supply (UK 13A, Europe 16A) rated at 230 Volts, 1N , 50Hz. The ACT 7 is equipped with a UK plug (CEE 7/7) as standard.

If an extension cable is used the following specifications must be complied to.

Extension cable (length)	Extension cable (min. width)
max. 10 m 2,5mm	2
10 m and more 4,0mm	2

CAUTION

Improper use of cables or using insufficient cable type can cause short circuit and fire hazard

• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
• Use extension cable with the right specification (be aware that most domestic proprietary extension cables are 1,5mm^2 - this is not sufficient)
• If the cable is on a 'cable drum' then ensure that it is completely unwound in accordance with the manufacturer's instructions

Dismantling

Disconnecting/ turning off

Follow the steps below in order to disconnect the ACT 7.

Failure to follow the procedure may result in excess water being retained in the system which may spill when the ACT 7 is moved.

Step Action Illustration

1 Switch to standby mode. Keep the unit in this mode for at least 30 minutes in order to let the condensate pump drain the system.

2 When you have waited for 30 minutes, you can disconnect: a. mains power to room unit and b. power cord between heat exchanger and room unit.

3 Disconnect drain hose from the heat exchanger: a. Use a screwdriver to remove the blue collet from the hose connector. b. Push darker grey ring in' and pull at the same time the hose to remove. Repeat step b to remove the hose from the room unit.

4 Disconnect pipes from a. room unit and b. heat exchanger Pull the coupling of the female pipe adapter back in order to disconnect the pipes.

Be prepared with an old cloth or alike to wipe the water/glycol mixture up, since it will spill a bit, when the pipes are disconnected.

Operation

User interactions

General recommendation

Check condition of the device before use. If device is showing signs of damage contact your supplier immediately.

CAUTION

Operation without connected heat exchanger provokes an HP failure and can damage the recirculation pump

If the ACT 7 room unit is operated in air conditioning mode while the heat exchanger is disconnected, the room unit will enter a high pressure state and automatically shut down the unit. There is a risk of damaging the recirculation pump.

• The ACT 7 room unit must only be operated (specifically in Air Conditioning mode), when connected to the heat exchanger with the interconnecting line provided.

Adjusting the air flow direction

The air outlet at the top of the ACT 7 room unit is fitted with grilles that allow the angle of air outlet to be adjusted.

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 draughts.

NB: An alternative top panel with twin 7^ ducts is available.

NOTICE

If the air flow is blocked an HP or LP failure can be provoked and shut down the unit

• Never put anything on top of the device or block the air in- and outlets.

Fig. 4: Care should be taken to avoid outlet air being obstructed as this will cause the air to rebound around the device resulting in recirculation and incorrect control of the device.
Fig. 5: Ideally, the air should be directed to create a 'blanket' of cold air across the ceiling area allowing natural convection to drop the air over the whole area at very low velocity.
