under pressure.

Never place the unit in a ammable atmosphere

Place the unit in such a way that it is not blocking

or hindering walking areas, doors, windows or similar.

•Ensure adequate space around the unit for air

circulation and to open doors. Refer to picture1

for minimal values of distance to walls.

• Avoid installing the unit in locations which are daily

exposed to direct sunshine for longer periods.

•Avoid installing the unit in aggressive and dus-

ty environments.

•Ensure a foundation with horizontal surface

(less than 3° slope), strong and stable enough

to carry the entire unit weight and to eliminate

vibrations and interference.

•The unit ambient temperature may not exceed

52°C during o-cycle.

•Ensure that the power supply corresponds to

the unit characteristics (see nameplate).

•When installing units for HFC refrigerants, use

equipment specically reserved for HFC refri-

gerants which was never used for CFC or HCFC

refrigerants.

•Use clean and dehydrated refrigeration-grade

copper tubes and silver alloy brazing material.

•Use clean and dehydrated system components.

•The suction piping connected to the compres-

sor must be exible in 3 dimensions to dampen

vibrations. Furthermore piping has to be done

in such a way that oil return for the compres-

sor is ensured and the risk of liquid slug over in

compressor is eliminated.

• For all units factory setting of fan speed

controller to be 15 ±1 bar.

• For refrigerant R134a, adjust the factory pres-

sure setting of XGE-2C (code no: 061H3144)

4 – Installation

•The installation in which the condensing unit is ins-

talled must comply to EU Pressure directive (PED)

no. 2014/68/EU. The condensing unit itself is not a

”unit” in the scope this directive. Under all circum-

stances local safety regulations must be fullled.

•The unit must be securely installed on a stable

and rigid support, and xed from the begin-

ning. See picture 2.

•It is recommended to install the unit on rub-

ber grommets or vibration dampers . Rubber

pads with mounting bolts are supplied.

•Slowly release the nitrogen holding charge

through the schrader port.

• Connect the unit to the system as soon as possible

to avoid oil contamination from ambient moisture.

•Avoid material entering into the system while

cutting tubes. Never drill holes where burrs

cannot be removed.

•Braze with great care using state-of-the-art tech-

nique and vent piping with nitrogen gas ow.

•Connect the required safety and control de-

vices. When the schrader port is used for this,

remove the internal valve.

•CU function and reliability is ensured/veried

for super heat 10K (SH 10K) condition so, it is

recommended to insulate the suction pipe up

to the compressor inlet with 19 mm thick insu-

lation.

5 – Leak detection

Never pressurize the circuit with oxygen or

dry air. This could cause re or explosion.

•Do not use dye for leak detection.

•Perform a leak detection test on the complete

system.

•The maximum test pressure is 32 bar.

•When a leak is discovered, repair the leak and

repeat the leak detection.

6 – Vacuum dehydration

•Never use the compressor to evacuate the system.

•Connect a vacuum pump to both the LP & HP

sides.

•Pull down the system under a vacuum of 500

μm Hg (0.67 mbar) absolute.

•Do not use a megohmmeter nor apply power

to the compressor while it is under vacuum as

this may cause internal damage.

7 – Electrical connections

•Switch o and isolate the main power supply.

•Ensure that power supply can not be switched

on during installation.

•All electrical components must be selected as

per local standards and unit requirements.

•Refer to wiring diagram for electrical connec-

tions details.

•Ensure that the power supply corresponds

to the unit characteristics and that the power

supply is stable (nominal voltage ±10% and

nominal frequency ±2,5 Hz).

•Dimension the power supply cables according

to unit data for voltage and current.

•Protect the power supply and ensure correct

earthing.

•Make the power supply according to local stan-

dards and legal requirements.

•

The unit is equipped with high and low pressure

switches, which directly cut the power supply to

the compressor in case of activation.

8 – Filling the system

•Wear protective stu like goggles and protec-

tive gloves.

•Never start the compressor under vacuum.

Keep the compressor switched o.

•Before charging the refrigerant, verify that the

oil level is between ¼ and ¾ on the compressor

oil sight glass. If additional oil is required please

refer to the compressors label for type of oil.

•Use only the refrigerant for which the unit is

designed for.

•Fill the refrigerant in liquid phase into the

condenser or liquid receiver. Ensure a slow

charging of the system to 4 – 5 bar for R404A.

•Do not put liquid refrigerant through suction line.

•It is not allowed to mix additives with the oil

and/or refrigerant

•The remaining charge is done until the instal-

lation has reached a level of stable nominal

condition during operation.

•Never leave the lling cylinder connected to

the circuit.

9 – Verification before commissioning

Use safety devices in compliance with both

generally and locally applicable regulations and

safety standards.

• Verify that all electrical connections are properly

fastened and in compliance with local regulations.

•When a crankcase heater is required, it must be

energized at least 12 hours before initial start-

up and start-up after prolonged shut-down

period.

10 – Start-up

•Never start the unit when no refrigerant is char-

ged.

•All service valves must be in the open position.

See picture 3.

•Check compliance between unit and power

supply.

•Check that the crankcase heater is working.

•Check that the fan can rotate freely.

•Balance the High Pressure / Low Pressure.

•Energize the unit. It must start promptly. If

the compressor does not start, check wiring

conformity, voltage on terminals and sequence

phase.

11 – Check with running unit

•Check the fan rotation direction. Air must ow

from the condenser towards the fan.

•Check current draw and voltage.

•Check suction superheat to reduce risk of slug-

ging.

•When a sight glass is provided observe the oil

level at start and during operation to conrm

that the oil level remains visible.

•Respect the operating limits.

•Check all tubes for abnormal vibration. Move-

ments in excess of 1.5 mm require corrective

measures such as tube brackets.

•When needed, additional refrigerant in liquid

phase may be added in the low-pressure side as

far away as possible from the compressor. The

compressor must be operating during this pro-

cess.

•Do not overcharge the system.

•Never release refrigerant to atmosphere.

•Before leaving the installation site, carry out

a general installation inspection regarding

cleanliness, noise and leak detection.

•Record type and amount of refrigerant charge

as well as operating conditions as a reference

for future inspections.

12 – Maintenance

Always switch o the unit at main switch

before remove fan panel.

Internal pressure and surface temperature

are dangerous and may cause permanent injury.

Maintenance operators and installers require

appropriate skills and tools. Tubing temperature

may exceed 100°C and can cause severe burns.

Ensure that periodic service inspections to

ensure system reliability and as required by local

regulations are performed.

This appliance is not intended for use by per-

sons (including children) with reduced physical,

sensory or mental capabilities, or lack of expe-

rience and knowledge, unless they have been gi-

ven supervision or instruction concerning use of

the appliance by a person responsible for their

safety. Children should be supervised to ensure

that they do not play with the appliance

To prevent system related problems, following

Periodic maintenance is recommended:

•Verify that safety devices are operational and

properly set.

•Ensure that the system is leak tight.

•Check the compressor current draw.

•Conrm that the system is operating in a way

consistent with previous maintenance records

and ambient conditions.

•Check that all electrical connections are still

adequately fastened.

•Keep the unit clean and verify the absence of

rust and oxidation on the unit components,

tubes and electrical connections.

The condenser must be checked at least once

a year for clogging and be cleaned if deemed

necessary. Access to the internal side of the

condenser takes place through the fan panel.

Microchannel coils tend to accumulate dirt on

the surface rather than inside, which makes

them easier to clean than n-&-tube coils.

•Switch o the unit at main switch before re-

move any panel from the condensing unit.

•Remove surface dirt, leaves, bres, etc. with

a vacuum cleaner, equipped with a brush or

other soft attachment. Alternatively, blow com-

pressed air through the coil from the inside out,

and brush with a soft bristle. Do not use a wire

brush. Do not impact or scrape the coil with the

vacuum tube or air nozzle.

If the refrigerant system has been opened, the

system has to be ushed with dry air or nitrogen

to remove moisture and a new lter drier has to

be installed. If evacuation of refrigerant has to be

done, it shall be done in such a way that no refri-

gerant can escape to the environment.
