1.0 HOW THE CALOREX ‘AA300’ WORKS

The Calorex ‘AA300’ is a packaged refrigerant type dehumidifier that is specifically designed to provide humidity
control and room heating (optional) for a swimming pool hall.

The Calorex ‘AA300 is designed to be connected into an air distribution system that will provide a uniform flow of
air through out the hall. An optional fresh air entry point is available.

The Calorex ‘AA300’ works by physically removing excess moisture from the pool hall air. This is achieved by
recirculating air from the pool hall through the unit and removing moisture from the air by use of the machines
internal refrigeration circuit.

As a by product of this process the Calorex ‘AA300’ will convert the energy it has absorbed into sensible heat.
This heat is added back into the return air stream and consequently provides supplementary hall heating. For every
1kw of power consumed the Calorex ‘AA300 ‘ will return approximately 2.5kW of heat. This process is controlled
by a humidistat that measures the pool hall humidity and controls the machine to a set point that can be adjusted
to suit the clients need.

As an option the Calorex ‘AA300’ can be supplied with a low pressure hot water (LPHW) air heater. The LPHW
should be fed with hot water at 80ºC# and will provide space heating for the pool hall. The LPHW is integrally fitted
into the Calorex ‘AA300’ and is supplied with an adjustable thermostat, three way control valve and a switch relay
to control a boiler or pump. The boiler and pump are not supplied with this option.

# Note.
Consult Calorex for heat exchangers that are suitable for lower flow temperatures.

Principles of operation - air to air dehumidifier

The process of dehumidification involves moisture laden air being drawn through a refrigerated
coil (evaporator). At this point the air is rapidly cooled below its dew point, condensing the water
vapour and recovering its latent heat energy for reuse. The cooled air is then passed across a
condenser where it is reheated and returned to the room as warm, dry air.

FEATURES :-

1.Remote control panel

The Calorex ‘AA300’ is supplied as standard with a remote control panel that can be mounted up to 20m
away from the unit. (The cable supplied with the AA300 is 1.8m ).The control panel features 12V circuits and
interconnecting cable is easily connected to the unit by ‘D’ type fittings.

The control panel will indicate pool hall humidity through an adjustable set point digital humidistat, power on,
fault, machine ‘dehumidifying’ and defrost status. An on/off switch is also provided.

When the unit is supplied with an optional LPHW the panel will also indicate pool hall air temperature through
an adjustable set point thermostat. A time clock will allow ‘set back air temperature’ for unoccupied periods. An
indicator light will show when the unit is heating.

The power to each model in the range is fed via din rail mounted terminal blocks located in the electric

box of the unit.

CONTROL PANEL WITH LPHW FITTED

2. Variable speed centrifugal fan.

When the AA300 is delivered the fan is set to run at two speeds: medium speed when the machine senses a
demand for dehumidification (and air heating) and low speed for when there are no demands.

If little or no ducting is fitted and the air flow is too high, the top speed of the fan can be changed from high to
medium. See instructions on page 10 and circuit diagram in section 2.5 for instructions on how to do this.

When fitting the remote sensor box it is possible to switch off the low speed fan MCB thus making the fan run
only when there are demand for dehumidification and/or air heating. See page 25.

1.1 OPERATION

The AA300 is connected to the control panel and then to the isolated mains supply as described in section

2.3. The isolator is then energised. The MAINS light on the side of the heat pump will illuminate indicating mains
ON. If the AA300 is fitted with an LPHW the time clock will start to run. The time clock has a battery reserve fitted
which when charged will run for 100 hours so that isolating the machine for short periods will not affect the time
clock settings.

The AA300 unit is switched on to normal operation by an ON (I)/OFF (O) switch on the console.

When switched on the red indicator light will illuminate and digital controller(s) will light up.

Providing that the controls are set to the correct parameters; nominally 60% RH, (28ºC air temperature), the
machine will operate automatically.

For AA300s with LPHW fitted, the ‘unoccupied’ temperature is set on the digital air controller and will be
switched in/out by the time set on the time clock.

As the unit operates, the indicator lights will show the state of the control conditions, ie dehumidification,
heat to air.

See section 3.0 for control panel symbols.

PARAMETER CONTROLLERS

Each parameter, Relative Humidity (and Air Temperature) is sensed within the machine and the signal is taken to
the relevant digital controller.
The RH controller has two switching channels, OUT1 (the Set Point) which is set from the front panel, and OUT2
which is factory preset.
When fitted, the Air Temperature has three switching channels, one of which is for setting the OCCUPIED/
UNOCCUPIED air temperature. (See section 1.2)
Each channel has a switching differential which is also factory pre-set. None of the factory settings should be
tampered with.
When the re-settable channel is adjusted all other settings and differentials automatically follow at the correct
relationship.

Nominal set point values & diffs RH% = 60% diff 3%

Air temperature = 28ºC diff 0.5 ºC

Please note: on AA machines with LPHW, in occupied mode dehumidification stops once the Air temperature is

2.5ºC above set point.

1.2. HUMIDITY & AIR TEMPERATURE AND CONTROLS

HUMIDITY DIGITAL CONTROLLERS

To Program the Set Point. Press down P, SP1 and Set Point value will be displayed alternately.
Press the or key to change the value of SP1. Once the desired value is displayed press P to memorise the
value. The display will revert to the present reading.
NOTE: If anything else shows on the display leave alone for 1 minute until the display returns to normal.

AIR TEMPERATURE DIGITAL CONTROLLER AND AA MACHINES WITH AIR HEATING

The digital controller for controlling air temperature can be changed as follows:­To program the set point, press P button once and release it. SP1 (set point) and set point value
e.g. 28 will be displayed alternately. Press P again AL1 (-4.5) will show. This is the difference between
the set point and AL1 plus a constant 0.5 e.g. 28 - 4.5 + 0.5 = 24ºC (unoccupied) SP1 and AL1 can be
changed in the same way as described for humidity and air.
NOTE: AL1 can only be set -1 to -10 below SP1 value.

NOTE: If the readings on the digital controllers are not the same as the actual pool hall conditions, an offset into
the digital controller can be set. However, before this is done an inspection of the installation should be made to
ensure air conditions into the unit are the same as those in the pool hall. Air leakage into the units return air from
other spaces should be sealed before adjustments are made. See technical manual.

1.3 TIME CLOCK SETTINGS

TIME CLOCK AA 300 with LPHW only

The time clock is a quartz 24 hour clock with 100 hours battery reserve used to control the automatic operation on
the AA300 unit per 24 hour time cycles.
The time clock setting determines the OCCUPIED/UNOCCUPIED periods and is set to match the operators

requirements regarding opening and closing times for the pool and possible times where the pool is covered.
The two settings are OCCUPIED or day time, and UNOCCUPIED or night time (covered).
The most obvious action of this change is to lower the pool hall air temperature to a determined level to
conserve air heating energy. This lowering of temperature is allowable because of the quiescent, and ideally
covered, condition of the pool.

Pool water occupied (no pool cover)

Pool water unoccupied (pool covered)

SETTING ACTUAL TIME

Turn the large clock hand clockwise until the correct time of day is set, ensuring that the correct half of the day is
chosen (24 hour clock).

SETTING FOR AUTOMATIC OCCUPIED/UNOCCUPIED OPERATION WITH TIME CLOCK

To set for automatic time clock control of occupied/unoccupied, slide the lever to ‘A’. Each yellow segment
represents a 15 minute time period. Extend outward the segments for a period of time when the pool is occupied
(i.e. used or uncovered) per day.

SETTING FOR AUTOMATIC OCCUPIED/UNOCCUPIED OPERATION WITH REMOTE INTERFACE

To set for remote control of occupied/unoccupied, slide lever to ‘O’. See section 2.3.2, Note 1 for more information
on remote interface.

SETTING FOR MANUAL OCCUPIED/UNOCCUPIED OPERATION

To set for manual occupied period (or override automatic unoccupied period) slide the lever to ‘I’ for ‘occupied’.

2.1 PLUMBING

CONDENSATE DRAIN

The condensate driptray in the ‘AA300VHF’ unit collects the water removed by the dehumidification process.
It is therefore necessary to ensure that the’AA300VHF’ unit is placed on a level plinth so that the condensate
can run away and not overflow the edges of the driptray inside the machine.
The ‘AA300VHF’ has a 3/4” BSPM threaded condensate drain connection. The drain pipe should
run away with adequate fall to waste ie 1/2” per foot minimum and must incorporate a ‘U’ trap & tun dish.

BOILER PLUMBING

The boiler connections on the machine are 3/4”BSPM. for connecting the boiler water flow and return.
Suitable breakable couplings, isolation, and drain down valves should be installed in the boiler water
flow and return pipes local to the ‘AA300VHF’ unit.
Refer to the boiler manufacturers instructions before designing the pipework system.

IMPORTANT GENERAL CONDITIONS

1) Do not route water pipes across service access panels or air inlet/outlets.

2) The water circuits to and from the ‘AA300VHF’ unit should be capable of maintaining the specified
water flow limits required by the machine. See Data sheet section 4.0.

3) All pipework must be adequately supported with allowance for expansion and contraction especially with
regard to the plastic pipework.

4) It is recommended that when installing water systems the last connections to be made should be
adjacent to the ‘AA300AVHF’ unit to avoid undue stresses on the unit connections.

2.3 ELECTRICAL INSTALLATION

ELECTRICAL SAFETY

It is important to ensure that all aspects of the installation comply with the latest I.E.E. Regulations.
It is also important to ensure that any remote devices which terminate within the pool hall are of the type and
voltage as specified in the latest I.E.E. Regulations.

The machine should be installed in accordance with EMC2004/108/EC.

PROTECTED SUPPLY

Whilst not mandatory, Calorex recommend that an R.C.C.B. is always fitted or that the supply is to local
electricity authority recommendations, and that all ducting is bonded in accordance with these regulations.
The supply to the machine should incorporate fuses or motor rated circuit breakers (type GU) to specified rating
(see data sheet) H.R.C. fuses are recommended. An all pole swtched isolator must be fitted within clear view of
the machine and not more than 2 metres away. The isolator must have a minimum of 3mm air gap when in the off
position.

INCONSISTENT ELECTRICAL SUPPLY.

The following limits of operation must not be exceeded if Calorex machines are to be guaranteed either in
performance or warranty terms :-

Voltage single phase - 207V min, 253V max
Frequency - 47.5Hz min, 52.5Hz max.

N.B The voltage must be measured at the heat pump mains terminals with all the fans/compressors
running at the rated condition.

CORRECT CABLE SIZING

The cable supplying electricity to a machine with a given load must increase in cross sectional area (CSA)
as the length increases in order that the voltage drop within the cable does not exceed recommended limits.
Cable sizing should be calculated by an approved electrician with due consideration to I.E.E. and local
codes of practice.

2.3.2 NOTES ON TERMINAL BLOCK CONNECTIONS

NOTE 1 - Remote occupied/unoccupied

These contacts (from terminals 10 & 11) are to enable the air temperature set back facility to be remotely
overridden.
There is a 12 V AC output from these terminals and closing a remote switch will enable the unit to regain the
normal operating air temperature for when the pool is in use.
This can be done via a voltage free pool cover switch or some other form of voltage free switch.
If this facility is used then the time clock (if fitted) on the control panel of the unit should be set to the
‘unoccupied’ (o) position. (See note on time clock and switch settings, section 1.3).

NOTE 2 - Boiler demand -AA+LPHW machines only

These are voltage free contacts (from terminals 6 & 7) rated at 3(1) Amp at 230 Volts.
If the low pressure hot water supply to the unit is to be governed by the Calorex unit then these contacts should
be utilised to bring water to the unit via the boiler, motorised valve, boiler pump etc. Remember the maximum
inductive load is one amp.
This is dependant on how the low pressure hot water supply to the unit has been designed.
If the supply of low pressure hot water to the unit is not dependant on a signal from the unit then these contacts
can be ignored.

NOTE 3 - RUNNING FAN IN ‘NON F’ MODE

If when the AA300 is installed the airflow is greater than necessary due to there being little or no ducting fitted,
the speed of the fan can be lowered, making the machine a non ‘F’. This is done by changing the fan speed from
high to medium by moving the white/black 1.0 wire from the electric box terminal 18 to terminal 17 (so that it is
now linked to blue fan lead).

CONTROL PANEL 25 WAY CABLE CONNECTION

Data signal between the console and the heat pump is via a 25 way cable with ‘D’ connection (plug & socket)
both ends. The cable provided with the heat pump is 1.8m in length. An optional 10m cable is available, part
number SD434052. A recommended maximum distance between the console and the heat pump is 20 metres, 2
cables being used.

Page 16

2.4 COMMISSIONING CHECKLIST

a) Is the building finished in accordance with the original plans and specification.

b) Is the plenum chamber and all ductwork insulated, special attention should be made to the insulation of the

fresh air inlet ducting to prevent condensation problems.

c) Are there any significant draughts in the pool hall or plant room (plenum installation) through poorly fitting doors,

windows, pipe ducts, etc. This will let in unwanted ambient air raising the heating duty required.

d) Is fresh air ducting (if fitted) perfectly sealed from plant room.

NOTE: (c) and (d) above should be checked by measuring plant room and pool hall air temperatures.If the plant

room is acting as a plenum chamber both temperatures should correspond. If the plant room temperature is

lower then ambient air is leaking in, this leak should be located and rectified.

e) Are the fresh air inlets free from obstructions ie, undersize grilles, objects in the path of exhaust air deflecting it

back to the fresh air inlet, etc.

f) Is ‘occupied / unoccupied’ set correctly, (set with air thermostat) see section 3.2.2.

g) Is the time clock set correctly.

h) Has the fan speed been set to match the sensors fitted.

j) Any sign of abnormal operation such as water dripping should be reported immediately to an installer or Calorex.

k) Has fan run amps been recorded against datasheet.

l) Has the unit been installed to allow service personnel access to all areas.
