AQUALEAN - AWC/AWH - MIL118E-1407 / 10-2013

INSTALLATION

2.1.- PRE - INSTALLATION

Prior to install the equipment, make sure of the following points:

• Leave enough space for access to air supply, water section, power supply and condensed outlet.

• The water section must have the correspondent valves.

• Easy extraction of the air fi lter.

• Easy access to lateral panel for easy accessibility to all services of the unit.

• Unit must be mounted with antivibration.

• The electrical section must be done following legal normative

• Check that the tension is the same as installation place.

• Keep in mind power supply for maximum consumption for each unit.

• Check water quality, across analysis according to local normative. If quality of water is not good, it may be neces­sary to install a device to decalcify.

• The water must be analysed; the water circuit installed must include all items necessary for treatment of the water:
fi lters, additives, intermediate exchangers, bleed valves, vents, isolating valves etc... depending on the results of the
water analysis.

We do not advise operation of the units with open loops which can cause problems with oxygenation, or
operation with untreated ground water.

Use of untreated or improperly treated water can cause deposits of scale, algae and sludge or cause corrosion and
erosion. It is advisable to call in a qualifi ed water treatment specialist to determine what kind of treatment will be
necessary. The manufacturer cannot accept liability for damage caused by the use of untreated or improperly treated
water, salt water or brine.
Here are our non exhaustive recommendations given as an indication:

• No NH4+ ammonium ions in the water, they are very detrimental for copper. <10mg/l

• Cl- Chloride ions are detrimental for copper with a risk of perforations by corrosion by puncture. < 10 mg/l.

• SO42- sulphate ions can cause perforating corrosion.< 30 mg/l.

• No fl uoride ions (<0.1 mg/l).

• No Fe2+ and Fe3+ ions with dissolved oxygen. Dissolved iron < 5 mg/l with dissolved oxygen < 5 mg/l. Over

those values, it means a corrosion of steel which may generate a corrosion of copper parts under deposite of Fe –
this is mainly the case with shell and tube heat exchangers.

• Dissolved silicon: silicon is an acid element of water and can also lead to corrosion risks. Content < 1mg/l.

• Water hardness: TH >2.8 K. Values between 10 and 25 can be recommended. This will facilitate scale deposit

that can limit corrosion of copper. TH values that are too high can cause piping blockage over time.

• TAC< 100.

• Dissolved oxygen: Any sudden change in water oxygenation conditions must be avoided. It is as detrimental to

deoxygenate the water by mixing it with inert gas as it is to over-oxygenate it by mixing it with pure oxygen. The
disturbance of the oxygenation conditions encourages destabilisation of copper hydroxides and enlargement of
particles.

• Specifi c resistance – electric conductivity: the higher the specifi c resistance, the slower the corrosion tendency.

Values above 3000 Ohm/cm are desirable. A neutral environment favours maximum specifi c resistance values.
For electric conductivity values in the order of 200-6000 S/cm can be recommended.

• pH: pH neutral at 20°C (7 < pH < 8)

It is very important that the unit works with water fl ows between maximum and minimum values according to the tables. You

h

ave to calculate water pump and install regulation valve if they are needed, in order to be sure that the unit works with water

fl

ow values indicated in the tables. Specially for heat pump units AWH in heating mode, if the unit works with water fl ow below

s

pecifi ed values, the unit can be seriously damaged, water exchanger can be frozen.

2.2.- UNIT INSTALLATION

Units must be installed by qualifi ed technicians. Any modifi cations done on the units will be made under customer´s
responsibility, and Lennox conformity declaration certifi cate will not be valid.

Hidraulic circuit:

• Make sure that water connections are correct, water inlet (down side), water outlet (upper side).

Lennox offers this element as an option.

• Install cut off valves at inlet and outlet water connections, because of in case of repairs, the hydraulic circuit can be
independent.

• Install water inlet and water outlet connections with a differential gauge device in order to see the pressure difference
between
the outlet an inlet connections.

• At the end Install an adequate water pump, and all the necessary elements for the installation

M

ake sure to disconnect power supply before carrying out any type of work on the unit

Water fi lter in the inlet water connection has to be used. The step of the mesh should be less
than Å 1.5 mm which avoids welded and dirty get to the unit. (Units 007 to 020

).

order to prevent the transmission of vibrations

.

AIR FLOW:

Airfl ow can be adjusted though the unit remote display between maximum/nominal/minimum
With “AUTO” the controller regulates the airfl ow between maximun and minimum values to assure the correct unit
operation mode.

DRAINAGE TUBE

• Use the fl exible tube connected to the drip tray as a drainage tube. Cause a siphon with this tube in order to avoid
the inlet of scents from the installation to the unit.
Install a siphon from the drainage tube of the drip tray with a difference in height of 80 mm to prevent from not evacua­ting due to the negative pressure created by the fans. The pipe will slope down 2% to make it easier for the conden­sates to drain off.

- Gas reheating values are below 12ºC.

If it is not correct, please check expansion system and refrigerant leaks.

• After supply the power to the unit and connect inlet/outlet water:

- Connect the gauges in high pressure and low pressure side.

- Use a temperature probe in the compressor gas pipe and another ones in the inlet and outlet water pipes.

- Start water pump.

- Make sure to close the unit all panels have to be correctly situated.

- Start the unit and make sure that the thermostat temperature adjustment is correct.

- Check the correct water fl ow with a differential gauge device connected between the inlet and outlet water connections in order
to know the pressure difference. Check it according to the capacity table values.

In addition, you can know the correct water fl ow with Dt measurement (inlet temperature ºC - outlet temperature ºC).
This value has to be the same as the value calculated with this formula:

- Outlet and inlet water temperature are correct according to the water fl ow which is between specifi ed values.
(Units 007 to 020).

• After verify the correct working mode, please stop the unit, disconnect the gauges and temperature probes. and

After a time delay, the unit will start.
With the unit operating, check that the fans are turning freely and in the correct direction.

CHECK THAT THE COMPRESSOR IS ROTATING IN THE CORRECT DIRECTION. (UNITS 012 to 020).

- If you have the option phase rotation indicator, use it to check the correct rotation.

- If you do not have three phase return lock, check the correct direction of rotation. The suction pressure decreases and the discharge

pressure increases when the compressor is started.

- If the connection is incorrect, rotation will be reversed, causing a high noise level and a reduction in the amount of current consumed.

If this occurs, the compressor’s internal protection system will operate to shut down the unit. The solution is to disconnect, reverse
two of the phases and connect again.

WITH OPERATING UNIT, CHECK:

- Low pressure and high pressure.

- Use the evaporating and liquid temperature to calculate superheat and subcooling.

- Adjust the refrigerant charge and/or expansion valve according to the preceding values.

COMPRESSORS WITH OIL LEVEL.

The oil level must always be checked. When the compressor is at rest, the level should be between 1/4 and 3/4
in the sight glass, while when running the level should be between 3/4 and full.
In the event of having to add oil, remember the type of oil is synthetic POE.
The original oil charge in the compressor is ICI Emkarate RL32-3MAF. This type of oil must also be used when replacing the oil completely.
When only topping up, RL32-3MAF or Mobil EAC Artic 22C can be used.

AQUALEAN - AWC/AWH - MIL118E-1407 / 10-2013

The unit must be installed in accordance with local safety codes
andregulations and can only be used in a well ventilated area.
Please readcarefully the manufacturer’s instructions before
starting this unit

All work on the unit must be carried out by a qualifi ed and
authorised employee.

Non-compliance with the following instructions may result in
injury or serious accidents.

Work on the unit:

The unit shall be isolated from the electrical supply by dis­connection and locking using the main isolating switch. Workers
shall wear the appropriate personal protective equipment (hel­met, gloves, glasses,etc.).

Electrical system:

Electrical connections can become loose during transport.
Please check them before starting-up the unit Compressors
with specifi c rotation direction. Check the correct rotation direc-
tion of the fan before closing the compressor circuit breakers.
If the direction is incorrect, the phases must be reversed at the
head of the main switch. Work on electric components shall be
performed with the power off (see below) by employees having
valid electrical qualifi cation and authorisation.

Refrigerating circuit(s):

After more than 12 hours of power cut, the cranckcase heater
(compressor) should be powered for 5 hours before any return
to service. Non-compliance with this instruction can cause dete­rioration of the compressors.
Monitoring of the pressures, draining and fi lling of the system
under pressure shall be carried out using connections provided
for this purpose and suitable equipment.

To prevent the risk of explosion due to spraying of coolant

and oil, the relevant circuit shall be drained and at zero
pressure before any disassembly or unbrazing of the refri­gerating parts takes place.
There is a residual risk of pressure build-up by degassing the
oil or by heating the exchangers after the circuit has been
drained. Zero pressure shall be maintained by venting the
drain connection to the atmosphere on the low pressure side.
The brazing shall be carried out by a qualifi ed brazier. The
brazing shall comply according to code ASME section IX fol­lowing the procedures specifi c.

Before starting up

- Test the circuit to the maximum working pressure(see the
nameplate)

- Verifi fy the operation of the high pressure swich.

- Check the piping and the components of the refrigerant
circuit.

Replacing components:

In order to maintain CE marking compliance, replacement of
components shall be carried out
using spare parts, or using parts approved by Lennox.
Only the coolant shown on the manufacturer’s nameplate
shall be used, to the exclusion of all other
products (mix of coolants, hydrocarbons, etc.).

CAUTION:

In the event of fi re, refrigerating
circuits can cause an explosion
and spray coolant gas and oil.

MAINTENANCE

5.1.- PREVENTIVE MAINTENANCE

PREVENTIVE MAINTENANCE PREVENTS COSTLY REPAIRS.

THIS REQUIRES PERIODIC INSPECTIONS:

- GENERAL ST ATE OF THE CASING:

Furniture, paint, damage due to shocks, rust spots, levelling and supporting, condition of the shock absorbers, if installed, screwed panels, etc.

- ELECTRICAL CONNECTIONS:

State of hoses, tightness of screws, earthing, current consumption of the compressor and fans and check that the unit is receiving the correct voltage.

- COOLING CIRCUIT:

Check that the pressures are correct and that there are no leaks. Check that there is no damage to the pipe insulation, that the condition of the coils

is good and that they are not blocked by bits of paper or plastic drawn in by the air fl ow, etc.

- COMPRESSOR:

If a sight glass is fi tted, check the oil level.
Check the condition of the silentbloc mountings.

- FANS:

Check that fans turn freely and in the correct direction without excessive noise.

- CONTROL:

Check Set Points and normal operation.

5.2.- CORRECTIVE MAINTENANCE

IMPORTANT

MAKE SURE THAT THE UNIT IS FULLY DISCONNECTED FROM THE POWER SUPPLY WHEN CARRYING OUT

ANY TYPE OF WORK ON THE MACHINE.

If any component in the cooling circuit is to be replaced, follow these recommendations:

- Always use original replacement parts.

- If the component can be isolated, it is not necessary to remove the entire refrigerant charge, if the component cannot be isolating and the refri-

gerant charge is removed, it should be removed through the Schrader valves located in the outdoor section. Create a slight vacuum as a safety
measure.

- Regulation prohibits the release of refrigerant into the atmosphere.

- If cuts must be made in the pipe work, use pipe cutters. Do not use saws or any other tools that produce fi lings.

- All brazing must be carried out in a nitrogen atmosphere to prevent corrosion forming.

- Use silver alloy brazing rod.

- Take special care that the fl ame from the torch is directed away from the component to be welded and cover with a wet rag to prevent overheating.

PRECAUTIONS TO BE T AKEN WHEN USING OF R-410A Refrigerant:

R-410A refrigerant is used in the unit; the following standard precautions for this gas should therefore be taken:

- The Vacuum Pump must have a Check Valve or Solenoid Valve fi tted.

- Pressure Gauges and Hoses for exclusive use with R-410A Refrigerant should be used.

- Charging should be carried out in the Liquid Phase.

- Always use scales to weigh-in charge

- Use the Leak Detector exclusive for R-410A Refrigerant.

- Do not use mineral oil, only synthetic oil to ream, expand or make connections.

- Keep pipes wrapped before using them and be very thorough about any possible dirt (dust, fi lings, burrs, etc.).

- When there is a leak, collect what remains of the charge, create a vacuum in the unit and completely recharge with new R-410A Refrige­rant.

- Brazing should always be carried out in a nitrogen atmosphere.

- Reamers should always be well sharpened.

- Take very special care if 4-way or check valves are to be replaced since these have internal components that are very heat-sensitive such as plastic, tefl on, etc.

- If a compressor is to be replaced, disconnect it electrically and un-braze the suction and discharge lines. Remove the securing screws and

replace the old compressor with the new one. Check that the new compressor has the correct oil charge, screw it to the base and connect the lines
and electrical connections.

- Evacuate above and below through the Schrader valves of the outdoor unit until -750 mm Hg is reached.
Once this level of vacuum has been reached, keep the pump running for at least one hour.

DO NOT USE THE COMPRESSOR AS A VACUUM PUMP.

- Charge the unit with refrigerant according to the data on the Rating Plate for the unit and check that there are no leaks.
