Application Guidelines
It should ensure that the refrigeration system
which adopts this condensing unit, wherever
possible to integrate pump down features.
This is to avoid liquid compression which
could damage the compressor.
Ensure that new compressors are not
subjected to liquid abuse. Turn the crankcase
heater on 12 hours before starting the

Health and Safety
Only qualified personnel, who are familiar
with refrigeration systems and components
including all controls, should perform the
installation and start-up of 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 installed in accordance
with all applicable standards and local by-laws.
General information
Before Installation
•Ensure the units received are the correct models for the
intended application.
•Ensure the refrigerant, voltage and maximum working
pressure are all suitable for the proposed application.
•Check there is no damage to the units. Any damage
should be reported to the supplier immediately.
•Check that the proposed equipment locations are
suitable and provide adequate support for the weight
of the units.
Offloading and Lifting
•Whenever a condensing unit is lifted, it should be from
the base and, where possible, all packing and
protection is kept in position.
•If lifting equipment is required, ensure that it is suitable,
certificated, and that the operators are qualified to
use it.
•When using a fork-lift or pallet truck to lift the unit, the
two support points should be sufficiently apart to give
stability when lifting and suitably placed to distribute
the load on the forks.
•If slings are used, care should be taken to ensure that
the slings do not crush the casework or coil.
•When lifting by crane, use spreader bars to prevent
compressing the top of the equipment.
•Do not drop the unit. Should this inadvertently happen,
it should be immediately unpacked and inspected for
damage.
•Use the appropriate spreader bars/lifting sling with
the holes and lugs provided.
During Installation and subsequent maintenance
•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.
•Safe working methods are identified, and operators
should/must have suitable Personal Protective
Equipment (PPE).
•Ensure the working area has adequate ventilation
during brazing procedures.
•The units contain moving machinery and electrical
power hazards, which 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, recovery, handling, and leak testing
procedures must be observed all the time.
•Units must be grounded to the screw terminal labelled
•No maintenance work should be attempted prior to
disconnecting the electrical supply.
•The electrical covers and fan guards must remain fitted
all the time.
•Use of the units outside of the design conditions and the
application for which the units were intended may be

Issue: 01.06.2023 Page 4
unsafe and be detrimental to the units, regardless of
short or long-term operation.
•The units are not designed to withstand loads or stress
from other equipment or personnel. Such extraneous
loads or stress may cause failure/leak/injury.
•The units are not designed to operate with any
restrictions such as heavy snowfall around them.
Additional measures (such as shielding of the units) shall
be implemented as required.
•The installer must fix the unit securely on installation
using the M8 bolt holes in the unit feet to prevent
instability from accidental contact or from exposure to
the elements (e.g.: wind).
•When the compressor operates under stabilized
conditions, the oil level must be visible in the sight glass.
Foam filling the oil sight glass indicates presence of
large concentration of liquid to the compressor.
•No additional oil is required for installation with good
oil returns, line runs up to 20m. Additional oil might be
required if lines exceeded 20m, with minimum oil level
must not lower than ¼ of sight glass (not applicable to
compressor without sight glass). Top-up the oil while
compressor is idle, via suction schrader connector with a
suitable pump.
•Ensure correct rotation of scroll compressor. If there is
no compression, shut off the incoming power supply
and swap connection of any two of the three incoming
phases at the condensing unit’s motor rated circuit
breaker.
Installation
Unit location
•To achieve maximum cooling capacity, the installation
location for the condensing unit should be carefully
selected.
•Install the condensing unit in such a way so that hot air
ejected by the condensing unit cannot be drawn in
again (short circuit of hot discharge air). Allow
sufficient space for maintenance around the unit.
Figure 1: Positioning of condensing unit
•Ensure that there is no obstruction to air flow into or out
of the unit. Remove obstacles which block air intake or
discharge.
Figure 2: Air circulation for condenser
•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.
•The unit must be level in all directions.
•It is recommended to install the unit on rubber grommet
or vibration dampers.
•Wall mounting on brackets is only suitable for models -
B1/-B2/-B3.
Special attention should be given if unit
installed near to the sea as this can reduce
unit lifespan due to corrosion of metal
parts.
Installation clearances
•The installation location should allow sufficient space
for air flow and maintenance around the unit.
Figure 3: Installation Clearance
Field Piping
Pipe sizing should only be determined by
qualified personnel. Correct line sizing will
minimize the pressure drop and maintain
sufficient gas velocity for proper oil return.
All applicable standards must be observed in the
installation of refrigerant piping.
To ensure satisfactory operation and performance, the
following points should be noted:
•Pipework routes must be as simple and as short as
possible.
•Avoid low points on pipework where oil can
accumulate.
•Suction gas velocity must be sufficient to ensure good
oil return.
•Use only clean, dehydrated refrigeration grade
copper tube with long radius bends.
•Avoid flare type connections and take great care when
brazing. Use brazing filler alloys containing phosphorus
such as BCuP-7 without flux for joining copper tubes.
•Dissimilar metals such as copper and brass shall be
joined using an appropriate flux with high silver
content filler material such as BAg-34. Apply flux
sparingly to the clean tube only and in a manner to
avoid leaving any excess inside of completed joints.

Issue: 01.06.2023 Page 5
•Run braze without over filling to ensure there is no
leakage into the tube.
•To prevent oxidation, blow oxygen free nitrogen
through pipework when brazing.
•To prevent condensation on pipe surface, install
insulation on all suction lines and on all pipes
penetrating walls or passing through hot areas.
•Adequately support all pipe work at a maximum of 2-
meter intervals.
•The maximum rise between the two units should be no
more than 6 meters, to ensure compressor ability to
handle pressure drop.
•In vertical pipework, the use of U-trap and double
suction risers is often required. These suction risers must
always be fitted with a U-trap at the bottom and a P-
trap at the top and never be higher than 4m unless a
second U-trap system is fitted.
•Additional oil may be required if piping length
exceeds 20m or multiple oil traps are fitted. Check the
oil level closely during commissioning and add oil as
necessary. Add oil in small amounts. Do not overfill the
compressor!
•Suction pipework should slope gently back towards the
unit to assist oil return to the compressor. A fall of
approximately 2cm per meter of pipework is
acceptable.
•Liquid lines should be sized to ensure a full supply of
liquid refrigerant to the expansion device. Attention
should be paid to the sizing of liquid lines on large
risers (maximum rise 6m).
•On systems with a large refrigerant charge and
without pump down cycle, or on any system where
liquid flood back is likely to occur, a suction
accumulator (not supplied) is strongly required. It offers
protection against liquid refrigerant flow back during
operation and against off-cycle migration by adding
internal free volume to the suction side of the system.
•Tests 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.
•Pump down control can be used on all thermostatic
expansion valve systems with the addition of a liquid
line solenoid valve. By closing a liquid line solenoid
valve, the refrigerant can be pumped into the
condenser and receiver, and the compressor operation
controlled by means of a low-pressure control. The
refrigerant can thus be isolated during periods when
the compressor is not in operation, and migration of
refrigerant to the compressor crankcase is prevented.
•In case of fire incidence, pressure increases due to
increasing in temperature at receiver. Hence it is very
important to install the Pressure Relief Valve.
•No valves and detachable joints shall be in areas
accessible to the public except when they comply with
EN 16084.
•Field piping for outdoor unit located below indoor unit:
Inverted P-trap is necessary when pump down is not
used (Figure 5). To prevent refrigerant from draining
into the compressor during off-cycle.
One of the main factors affecting
equipment reliability and compressor
service life is refrigeration circuit
contamination.
During installation, circuit contamination could cause by:
•Brazing & Welding Oxides
•Filings & Particles from de-burring pipework
•Brazing Flux
•Moisture & Air

Installation
Pressure Testing
Never use oxygen, dry air, or acetylene for
pressure testing of the system as these may
form an inflammable mixture.
•The condensing units are pressure tested in the factory
prior to dispatch. All units come with a holding charge
of oxygen free nitrogen ~2barg. Remove the holding
charge indication tag which is tied to service valve
before installation.
•Once the pipework installation is complete, it should be
pressure tested for leak prior to evacuation.
•A pressure leak test should be carried out using
oxygen free nitrogen (OFN). A calibrated nitrogen
pressure regulator must always be used. Before
starting any pressure testing, ensure the area
surrounding the system is safe, inform relevant
personnel and fit warning signs indicating high pressure
testing. Also, use correct PPE as required.
•Always pressurize the system slowly, preferably in
stages up to the maximum required pressure. Never
exceed maximum working pressures shown in below
table. Failure to obey the limit will cause premature
failure on the pressure safety device.
Table 3: Maximum working pressure
High Side, barg (psig)
Low Side, barg (psig)
28 (405)
19 (275)
•Listen for any possible leaks and check all joints with
bubble spray. If any leaks are discovered, release
pressure slowly from both suction and liquid line of
system until empty, repair leak and then repeat
pressure testing procedure. Never attempt to repair a
leak on a pressurized system.
•A strength test should also be incorporated (to the
installed pipework only) according to applicable
standards.
•Once testing has been completed satisfactorily, release
the pressure from the system gradually and safely to
external atmosphere.
Evacuation and Charging
Moisture prevents proper functioning of the
compressor and the refrigeration system.
Ensure that a good quality vacuum pump is
used to pull a minimum vacuum of 250
microns (0.25 torr) measured at refrigeration system, and
not at the vacuum pump gauge.
Once pressure testing has been completed, the system
needs to be evacuated to remove any moisture from the
piping. This can be done as follows:
•Ensure any nitrogen charge is safely released from the
system.
•Connect a gauge manifold to the connections on the
service valves on the condensing unit.
•Connect a vacuum pump and vacuum gauge to the
system.
•Ensure all gauge manifold and service valves in open
position.
•Evacuate the system until vacuum is below 250 microns
(0.25 torr).
Note: A triple evacuation procedure is recommended for
all new systems or where moisture is suspected.
•Once the system is isolated and the vacuum pump is
switched off, any rise in pressure indicates that either
there may be a leak in the system or moisture is still
present. In this case, recheck the system for leaks,
repair as necessary, and then repeat the evacuation
procedure.
•Once evacuation is completed satisfactorily, the
vacuum pump and vacuum gauge can be removed. At
this point, the refrigerant charge can be added to the
system as required. Refrigerant blend must be charged
in liquid form to avoid change of chemical properties.
•Ensure an adequate liquid charge (4~5barg) has been
introduced to the high side of the system before
starting the compressor.
•The remaining charge is slowly throttled into suction
side until the installation has reached a level of stable
nominal condition during operation. Charging liquid
into the suction side of the system should ONLY be
done with a metering device. Ensure a minimum
operating pressure 0.5 barg is maintained when
adding refrigerant to the suction side, otherwise
overheating of the compressor may occur. Use
calibrated weighing scales to record the amount of
refrigerant added to the system.
•Stop the filling once obtain sufficient suction superheat
and liquid subcooling, remove the cylinder from circuit.
Refrigerant charge by judging the liquid
sight glass does not guarantee as 100%
correct way.
Electrical
The mains electrical supply to the condensing
unit must be via a suitable motor rated circuit
breaker or fuse. A mains isolator is fitted to
all condensing units. Therefore, an additional
isolator is not required unless site conditions
or regulations dictate differently.
J & E Hall Fusion & Fusion Scroll condensing units require
power supply single or three phase which include Neutral
and an Earth. These systems are not suitable for any other
supply voltages (other than specified in Table 2).
•Mains supply cable type and size must be selected to
suit the application and the electrical installation should
conform to the current local standards.
•Cables to the condensing unit should, wherever
possible, be routed through the cable glands supplied
on the rear of the units.
•Connect the mains supply to the units as per the wiring
diagrams.
•Ensure that the power supply corresponds to the unit
and that the power supply is stable.
•Connect power supply according to the present norm
and legal requirement. Ensure that the unit is properly
connected to the ground.
•3phase scroll compressor: live wires need correctly
terminated at motor rated circuit breaker for the
compressor to rotate in correct direction (compression).

Issue: 01.06.2023 Page 7
•The unit is equipped with a motor circuit breaker with
thermal overload and magnetic trip short circuit
protection for the unit. It was preset from factory and
never set value higher than set current on wiring
diagram.
Reverse Rotation Protection and Voltage
Unbalance
The condensing unit does not include phase protector
except for model JEHS-1400-B4-L-3 EVI; JEHS-1500-B6-
M-3 and JEHS-1300-B4-M-3 units. Thus, it is necessary to
ensure correct scroll compressor rotation and incoming line
voltage variance within +/-2% during commissioning.
3 phase scroll compressors require proper
phase sequence to secure right rotation and
therefore compression.
•Do not use a megohmmeter nor apply power to the
compressor while the system under vacuum as this
may cause internal damage to the compressor.
•Never start the compressor under vacuum (do not
operate the compressor with the low-pressure cut-
out bypassing), as this will cause the rotating part to
overheat very quickly causing premature failure.
•There must be no more than 10 compressor’s start
per hour. A higher number reduces the service life of
the compressor. There is no minimum off time for the
compressors. Adequate minimum run time is
required to ensure proper oil return.
Commissioning
To gain access to the electrical box, turn the motor rated
circuit breaker on the side/front of the unit to the OFF
position and loosen the screws on the left-hand side of the
door. The electrical box is located behind the door. Remove
the screws in the electrical box cover to access components.
Pre startup checks
Before starting the condensing unit, the following checks
should be carried out as a minimum:
•Check electrical supply is correct and all connections
are sound.
•All moving parts are free, and guards are fitted.
•Compressor oil level satisfactory.
•Initial settings for safety switches and fan speed
control.
•Overload set correctly on motor rated circuit breaker.
•All valves are in correct operating position.
•Initial refrigerant charge.
•Crankcase heater energized for a minimum of 12 hours
before compressor start-up.
•Gauge manifold connected to both low and high sides
of system.
Running the unit
•Run the unit and check compressor and condenser fan
operation.
•Check system pressures and temperatures, gas charge
and running currents of motors to ensure correct
operation.
•Check compressor suction superheat. This should be
between 10K and 20K for normal operating
conditions.
•Final adjustment of safety switch settings and fan
speed control.
•Allow the system to run for 3 –4 hours. Check
compressor oil level and top up with the correct oil
type as required. Recheck the compressor oil level
again after 24 hours operation.
•Carry out final leak test and ensure all panels/covers
are fitted and screws tightened.
•Log all information along with the system model and
serial numbers for future reference.
•Ensure that the customer / responsible person is
provided with basic operating instructions and where
electrical isolators are situated in case of emergency.
Scroll Compressor Operation
Scroll compressor motors are designed to run only in one
direction. This is not an issue with single phase compressors
as they will always run in the correct direction. The correct
rotation of a three-phase compressor motor depends on the
connection of the three incoming phases to the unit. Correct
rotation can be determined by a drop in suction pressure
and a rise in discharge pressure when the compressor is
energized. Running the compressor for a short period of
time in reverse direction will have no negative impact but
prolonged running in reverse direction may cause
premature failure. To reverse the rotation of a three-phase
scroll compressor, shut off the incoming power supply to the
unit, swap connection of any two of the three incoming phases
at the unit motor rated circuit breaker, reapply power to the
unit and following compressor restart, recheck operating
pressures.
Compressor rotalock connections
All rotalock connections on compressor models are sealed
with Loctite 554 thread sealant. The connections should be
leak tested at commissioning and during
service/maintenance visits. Refer Table 13 for more
information including recommended tightening torque.
Dual Pressure Switch
The dual pressure switch fitted to condensing units is auto
reset for low pressure side and manual reset for high
pressure (fixed differential) are NOT factory preset for
application.

When HP switch cut out mode is changed
from Manual to Auto operation, the fitting of
an ART (anti-recycle timer) is recommended
to protect the compressor.

Pressure switch settings
Both the LP and HP switch settings must be adjusted to
suit application before starting the unit. Ensure that the
high-pressure setting does not exceed the value shown in
Table 5.
High pressure safety
•The high-pressure safety switch is required to stop the
compressor should the discharge pressure exceed the
compressor’s high side operating pressure.
•The high-pressure switch can be set to lower values
depending on the application and ambient conditions.
Low pressure protection
•The low-pressure protection cut out switch protects the
compressor against deep vacuum operation, a
potential cause of failure due to internal arcing and
operating outside the compressor limits.
•The low-pressure protection cut out should never be set
lower than the min. LP cut out value in Table 5. For
systems without pump-down integrated, the LP switch
signal contact shall be used to energize a low-pressure
safety alarm.
•If a thermostat is used for room temperature control,
and a pump down feature is not integrated, a low-
pressure control of the manual reset type should be
wired in series with the thermostat to serve as a
protection cut-off in the event of loss of refrigerant
charge or other abnormal conditions which resulting in
low suction pressures.
•When used for low temperature operational control,
the low-pressure control should be provided with a low
differential for accurate control. For accuracy,
refrigeration gauges must be used in setting cut-in and
cut-out points, since the indicator on the face of the
pressure switch is not sufficiently accurate for control
purposes.
•Compressor operating pressures should be kept within
the limits in Table 5.

Crankcase Heaters
•Crankcase heater should remain energized during the
compressor off cycles. The initial start in the field is a
very critical period for any new compressor because
all load-bearing surfaces are new and require a short
break-in period to carry high loads under adverse
conditions. Thus, the crankcase heater must be turned
on a minimum of 12 hours before the first-time start, to
prevent oil dilution and bearing stress on initial start-
up.
•To energize the crankcase heater while keeping
compressor OFF, isolate the compressor from circuit by
removing jumper wire which in series with H/L pressure
switch, such as terminal 3-4 in Series 2, and then turn
the motor rated circuit breaker to ON position.
Fan Speed Controller XGE-4C
(Applicable to Series 2/3/4 and 6)
•The fan speed controller is factory set to 19barg
(maximum speed) and cut off when drop below
13barg, for operation with R4*** series refrigerant to
ensure compressor always operates within the unit
operating envelope.
•When operate with R134a, the fan speed controller
setting need to be set to 13bar.

Discharge Thermostat
(Applicable to JEHS-0750-B4-L-3, JEHS-1300-B4-M-3,
JEHS-1500-B6-M-3 and all EVI)
Only scroll models specified above are equipped with
discharge thermostat with specification (cut out = 125±4⁰C,
cut in = 95±5⁰C). The thermostat is connected in series to
dual pressure switches, to disconnect all three phases at
contactor in case of overtemperature.
For other 3phase models, it is recommended to install the
discharge thermostat with cut out temperature not more
than the maximum discharge gas temperature specified
in Table 2.
Overheating could be due to compressor working at high
compression ratio (low evaporating and high condensing
pressure); loss/ inadequate charge; or condenser fan not
working. Time must be allowed for the compressor to cool
down before the thermostat auto reset.
For scroll compressors with motor protection code “F”, an
internal line break motor protector is located at the center
of the Y of the motor windings (motor located in low
pressure dome), to disconnect all three phases in case
overcurrent or overtemperature condition. The protector is
the automatic reset device containing snap action bimetal
switch which reacts to a combination of motor current and
motor windings temperature. When the internal motor
protector has tripped, it will take 30 to 40 minutes to reset
and then the compressor will restart.
On a field application, when the internal motor protector
has tripped, the compressor will stop while each of 3
terminals is still energized, to which either the customer or
serviceman may regard the compressor as fail down.
Therefore, the above-mentioned situation should be taken
into consideration.
Units with microchannel condenser
•Care must be taken during charging a unit where a
microchannel condenser coil is fitted.
•The microchannel coils hold less refrigerant than
traditional fin/tube coils, it is easier to be overcharged,
especially if the system is commissioned during
wintertime which ambient temperature is colder.
•If too much refrigerant is added, this may cause
tripping of the high-pressure switch in warmer weather.
•Always check that the amount of condenser sub cooling
is not excessive which may indicate refrigerant
overcharge.
System operation
•Once the system is correctly charged with refrigerant
and the operating condition is stable, check that the
compressor suction superheat is between 10K~20K
and that the compressor discharge temperature is
between 50°C~ 90°C.
•A compressor suction superheat that is too low may
indicate liquid refrigerant return to the compressor,

whereas a suction superheat that is too high will not
provide enough cooling effect for the compressor and
will cause high discharge temperatures. In either case,
it is likely that compressor damage/failure will occur.
Precautions when operate with FH and AJ
Compressor
Follow instructions below when operating R448A/R449A in
low temperature condensing unit which integrated with
Tecumseh compressor FH/AJ.
Limit the suction superheat below 10K, to
ensure discharge temperature is maintained
below 120ºC with evaporating temperature
of -30ºC and below. Do not use capillary
tubes as throttling devices to prevent plugging issue.
Voltage Monitoring Device MG73BF
(Applicable to JEHS-1400-B4-L-3 EVI; JEHS-1300-B4-M-3
and JEHS-1500-B6-M-3 units only)
Only the above models are equipped with voltage
monitoring device to monitor the input power supply to

Vapor Injection Controller EXD-HP1
(Applicable to EVI units only)
The controller EXD-HP1 used in the EVI units operates as an
economizer control. The setting of the controller is factory
pre-set and is password protected. Users are not
recommended to change any settings in the controller.
Electronic expansion valves in the EVI unit
are in partially open condition. Do not
charge the system with refrigerant before
closure of valve.
Four main parameters Password (H5), type of function
(1uE), refrigerant type (1u0) and pressure sensor type (1uP)
can be set only when digital input DI1 is off
(open) while the power supply is ON (24Vac).
Digital input Di1
•The digital status is dependent on the operation of
system’s compressor or demand.
Table 9: Digital input status of EXD-HP1

Closed (Start)
Compressor stops
Open (Stop)
Electrical checked/modified before start-up
•To fully close the EEV, open circuit Di1-gnd of controller
through disconnecting the supply to compressor. For
1. Model JEHS-0951/1150-B4: remove the jumper
wire from terminal block labeled 8 and 9.
2. Model JEHS-1300-B5: remove twin jumper bars
from terminal blocks labelled 6 and 7.
•Switch ON the motor rated circuit to turn ON the power
supply 24V to the controller EXD-HP1. The valve will
be driven to a close position.
•After closure of the EEV valve, start charging the
system with refrigerant.
•Disconnect power supply through motor rated circuit
breaker, then reconnect back the original wiring from
factory.
•Do not apply voltage to the system before all cable
connections are completed.
•Use a class II category transformer for 24 Vac power
supply. Do not ground the 24 Vac lines.
•Higher voltage than specified will permanently
damage the controller.
•When connecting wires of EEV and pressure sensor
4~20mA to the controller EXD-HP1, follow the cable
color to connect to the respective abbreviation color
code printed on the EXD-HP1. Example for EXV: BR =
Brown; BL = Blue etc. Or refer to wiring diagram for
electrical connections.

•In the case of economizer control. The discharge
temperature is shown on the display.
•To display other MEASURED DATA on EXD-HP1, press
“SEL” button for 1 second until index number according to
below table appears. Release “SEL” button and the next
variable data will be displayed. Repeating the

Note: After 30minutes, the display reverts to index 10.
Manual mode operation
•Manual mode is intended for temporary operation of
the valve at specific condition. Warning: All alarms are
disabled during manual operation. We do not
recommend unattended operation of the system during
manual control.
•Press and together for 5seconds to access to
manual mode operation.
•After achieving the required operation, set the
parameter 1Ho and 1HP at 0, so the controller
automatically operates the valve at its setpoints.
