the system. To avoid potential injury, use care when
working around coil surfaces or sharp edges of metal
cabinets. All piping and electrical wiring should be
ordinances and local by-laws.
This appliances is not intended for use by persons
(including children) with reduced physical, sensory or
knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person
supervised to ensure that they do not play with the
appliance.

230V/50Hz/1PH
• Ensure the unit received is the correct model for the
intended application.
• Ensure refrigerant, voltage, are suitable for the
proposed application and environment.
• Installation and maintenance are to be performed only
by qualified personnel who are familiar with local codes
and regulations, and experienced with this type of
equipment.
• The condensing unit is delivered with a nitrogen holding
charge.
• The condensing unit contains moving machinery and
electrical power hazards. May cause severe injury or
death. Disconnect and shut off power before installation
or service of the equipment.
• Refrigerant release into the atmosphere is illegal.
Proper evacuation, handling and leak testing
procedures must be observed at all times.
• Condensing unit must be earthed.
Improper earthing may result in electric
shocks or fire.
• Be sure to switch off the unit before touching any
electrical parts. Touching a live part may result in
electric shocks or fire.
• The electrical covers and condenser fan guard must
remain fitted at all times.
• Use of the condensing unit outside of design conditions
and application for which units were intended may be
unsafe and be detrimental to the unit, regardless short
or long term operation.
• The condensing units are not designed to withstand
loads or stresses from other equipment or personnel.
Such extraneous loads or stress may cause
failure/leak/injury.
• In some circumstances, a suction accumulator (not
supplied) component may be required, it offers
protection against refrigerant flood back during
operation. It helps protect against off-cycle migration by
adding internal free volume to the low side of the
system.
• Test must be conducted to ensure the amount of off-
cycle migration to the compressor does not exceed the
compressor’s charge limit.
• Wherever possible the system should be installed to
utilize a pump down configuration. For unit Series 1
JEHCCU040CM1 and JEHCCU0050CM1, it is
advisable to connect with thermostat cut off
configuration using the reserved terminal in control box.
• After installation, the system should be allowed to run
for 3 – 4 hours. The oil level should be checked after 3
– 4 hours run time and topped up as necessary. The oil
level should not be lower than quarter of the
compressor oil sight glass.

3. Installation & Commissioning
3.1 Unit site location
• In order to achieve maximum cooling capacity, the
installation location for condensing unit should be
carefully selected.
• Install the condensing unit in such a way so that hot air
distributed by the condensing unit cannot be drawn in
again (as in the case of short circuit of hot discharge
air). Allow sufficient space for maintenance around the
unit.
• Ensure that there is no obstruction of air flow into or out
of the unit. Remove obstacles which block air intake or
discharge.
• The location must be well ventilated, so the unit can
draw in and distribute plenty of air thus lowering the
condensing temperature.
• To optimize the unit running conditions, the condenser
coil must be cleaned at regular intervals.
3.2 Installation Clearance
• The installation location should allow sufficient space
for air flow and maintenance around the unit.
Air inlet
• To allow sufficient space for doing service or
installation.
3.3 Compressor handling
To ensure compressor reliability, the condensing unit and
the compressor must not be tilt greater than an angle of 45°.
3.4 Field Piping
Line sizing should only be determined by qualified
personnel. All local codes of practice must be observed
in the installation of refrigerant piping
To ensure satisfactory operation and performance, the
following points should be noted for field piping
arrangements,
• Couples one indoor unit with one outdoor condensing
unit only.
• Release all the pre-charged nitrogen before pipework
connection.
• Connecting pipe size for suction and liquid line must
same as attaches to the condensing unit. Correct line
sizing will minimize the pressure drop and maintain
sufficient gas velocity for proper oil return.
• Pipework routes must be as simple and as short as
possible. Avoid low points on pipework where oil can
accumulate.
• Use only clean, dehydrated refrigeration grade copper
tube with large radius elbows. The piping shall be kept
with enough bending radius.
• Braze without over filling to ensure there is no excess
solder into the tube.
• To prevent oxidation, blow nitrogen through pipework
when brazing.
• Install insulation on all suction lines after pressure test.
• Adequately support all pipe work at a maximum of 2
meter intervals.
• For the condition where the outdoor condensing unit is
above the indoor unit, the height difference between
units shall be less than 25 m and install oil trap on
suction pipe every 4 m height. The suction pipe must
always be fitted with U-trap at the bottom.
• For the condition where the outdoor condensing unit is
below the indoor unit, the height difference between
units shall be less than 4 m. Pipe trap shall be installed
upward on outlet of indoor unit (suction pipe).
• The recommended piping length is 25 m or less.
• Additional oil might be required in case field piping is
long or with many oil traps. Check the oil level of the

3.5 Pressure testing
• Make sure that both service valves are closed when
running a pressure test on field piping, always use an
inert, dry gas such as Nitrogen
• The pressure differential between the high and low side
shall not higher than below.
• Test pressures shall be as shown follows.
• If there is pressure drop, check the leakage portion.
3.6 Leak detection
• Make sure that all manual valves are open
• Perform a leak test of the system using nitrogen mixed
with the refrigerant to be used
• Do not use CFC for leak testing the condensing unit
which will be used with HFC refrigerants
• The use of leak testing fluids is not recommended as
this may interact with the lubricants own additives
3.7 Vacuum - moisture removal
Moisture prevents proper functioning of the compressor
and the refrigeration system
Air and moisture reduce service life and increase
condensing pressure causing abnormally high discharge
temperatures likely to destroy the oil’s lubricating properties.
The risk of acid formation is also increased by air and
moisture and copper plating can be generated in this way.
All these phenomena can cause mechanical and electrical
failure.

3.10 Commissioning of the Condensing Unit
Please make sure that all manual service valves are fully
open when starting the system for the first time. This
includes external and internal shut off valves as well as
liquid receiver valve in the unit.
The ball valve open position is shown as below:
• Check compressor oil level via compressor sight glass,
the oil level should not be lower than quarter of sight
glass.
• Check the TXV capacity sizing based on indoor unit
capacity. Check TXV applicable refrigerant. Check
position and condition of the sensing bulb fixing
• Observed the system pressures during the charging
and initial operation process.
• Ensure that suction pressure will decrease, discharge
pressure will increase. No abnormal noise from the
compressor.
• Continue to charge the system until sight glass is clear.
Make sure that high pressure is > 14 barg for R404A
and > 8 barg for R134a when doing this charge
adjustment operation. Continuous flow of clear
refrigerant through the sight glass, with perhaps an
occasional bubble at very high temperature indicates
the refrigerant is at optimum.
• Check the compressor’s discharge and suction
3.11 Compressor electrical wiring
Verification of proper rotation direction is made by observing
that suction pressure drops and discharge pressure rises
when the compressor is energized. Reverse rotation of a
scroll compressor also results in substantially reduced
current draw. Suction temperature will be high, discharge
temperature will be low and the compressor may generate
abnormal noise.
3.12 Earthing of Condensing Unit
Installation of earth wire must be made to earthing screw
(labelled with earth label) before connecting the live wires.
The earth wire shall be slack as shown in below diagram.
pressure, to ensure it is within operating range.
Discharge temperature should be within 50 to 90 °C
and pressure should be around 15 to 26 barg (for
system charged with R404A) and 8 to 16 barg (for
system charged with R134a).
• Check the current of condensing unit and ensure it is
below the motor circuit breaker setting value.
• Check condenser fan, ensure warm air blowing off the
condenser coil.
• Check evaporator blower, ensure it’s discharging cool
air.
• Check suction superheat and adjust expansion valve to
prevent liquid flood back to the compressor.
Recommended 5 to 20 K of suction superheat.
• Do not leave the system unattended until the system
has reached its normal operating condition and the oil
charge has properly adjusted itself to maintain the
proper level in the sight glass.
• Check periodically the compressor performance and all
the moving components during the first day of
operation.
• Check the liquid line sight glass and expansion valve
operation. If there is an indication that the system is low
on refrigerant, thoroughly check the system for leaks
before adding refrigerant.

4. Decommissioning & Disposal
At the end of the unit’s useful life, a suitably qualified
engineer should decommission it. The refrigerant and
compressor oil are classed as hazardous waste and as such
must be reclaimed and disposed of in the correct manner,
including completion of waste transfer paperwork. The unit
components must be disposed of or recycled as appropriate
in the correct manner.
5. Checklist
• Ensure the high low pressure controls are configured
properly.
• Ensure crankcase heater is energized minimum 12
hours prior to start up and permanently energized.
• Check the refrigerant is correct for intended use.
• Check all electrical connections.
• Check all electrical termination and circuits are correct.

Warning! – Disconnect the mains electrical supply
before servicing or opening the unit
Warning! – Ensure there is n o refrigerant in refrigerant
circuit before dismantle it
Warning! – If the supply cord is damaged, it must be
replaced by the qualified service agent in order to avoid
a hazard.
The condensing units are designed to give long life
operation with minimum maintenance. However, they should
be routinely checked and the following service schedule is
recommended under normal circumstances:
7. F-Gas Information
• From 1/1/2015, a new F-Gas Regulation (EU) No
517/2014 comes into force repealing Regulation
(EC) No 842/2006. This will affect system
labelling, information supplied within
documentation and also the way in which
thresholds for frequency of leak testing.
• For systems with a charge below 3kg, the
changes to the leak checking regime will not apply
until 2017. Currently, there is no requirement for
regular leak testing of systems with a total charge
below 3kg.
• Changes to leak testing requirements are as
follows:
For scroll compressor: wiring for 3 phases must be
controlled. Supply phase sequence L1, L2 and L3 will affect
the rotating direction of scroll compressor and damage the
compressor.
Service technician should be present at initial start- up to
verify that the supply power is properly phased and that
The removal of the top, side and front panels ensures that all
parts are accessible.

Additional advice:
1.
Do not leave the system unattended until the system has reached its normal operating condition
and the oil charge has properly adjusted itself to maintain the proper level in the sight glass.
2.
Check periodically the compressor performance and all the moving components during the first
day of operation.
3.
Check the liquid line sight glass and expansion valve operation. If there is an indication that the
system is low on refrigerant, thoroughly check the system for leaks before adding refrigerant.
