installing.

Do not install the unit where leakage of flammable gas may

•

occur.

If gas leaks and accumulates around the unit, it may cause
fire ignition.

•

Ensure that the drainage piping is connected properly.

If the drainage piping is not connected properly, it may
cause water leakage which will dampen the furniture.

•

Do not overcharge the unit.

This unit is factory pre-charged. Overcharge will cause
over-current or damage to the compressor.

•

Ensure that the unit’s panel is closed after service or
installation.

suction of the unit.

•

This unit is not suitable for factory used where cutting oil mist or
iron powder exist or voltage fluctuates greatly.

•

Do not install the units at area like hot spring or oil refinery plant
where sulphide gas exists.

•

Ensure the color of wires of the outdoor unit and the terminal
markings are same to the indoors respectively.

•

IMPORTANT : DO NOT INSTALL OR USE THE AIR
CONDITIONER UNIT IN A LAUNDRY ROOM.

•

Don’t use joined and twisted wires for incoming power supply.

•

The equipment is not intended for use in a potentially explosive

INSTALLATION OF THE OUTDOOR UNIT

Location For Installation

Install the outdoor unit in such way that air distributed by
the outdoor unit cannot be drawn in again (as in the case
of short circuit of discharge air). Allow sufficient space for
maintenance around the unit.
Ensure that there are no obstruction of air flow into or out
of the unit. Remove obstacles which block air intake or
discharge.

When two or more outdoor units are installed in a location,
they must be positioned such that one unit will not be taking
the discharge air from another.
This also applies when two or more units are installed one
above the other. The units must all face the same direction,
or opposite direction (back to back), such that air short circuit
does not occur.

The location must be well ventilated, so that the unit can draw and distribute plenty of air.
A place capable of bearing the weight of the outdoor unit and isolating noise and vibration.
A place protected from direct sunlight. Otherwise use an awning for protection, if necessary.
A place where smooth drainage of rain water and water formed by defrosting is acceptable.
A place where the unit will not be buried in snow.
A place where air outlet port is not exposed to strong wind.
A place where the air discharge and operating sound level will not annoy the neighbours.
The location must not be susceptible to dust or oil mist.

! CAUTION

If the condensing unit is operated in an atmosphere containing oils (including machine oils), salt (coastal area),

sulfide gas (near hot spring, oil refinery plant), such substances may lead to failure of the unit.

Installation Clearance

Outdoor unit must be installed such that there is no short circuit of the discharge air or obstruction to smooth air flow.

REFRIGERANT PIPING

Allowable Pipe Length and Elevation

If the pipe is too long, both the capacity and reliability of the unit will drop. As the number of bends increases, resistance to
the flow of refrigerant system increases, thus lowering cooling capacity. As a result, the compressor may become defective.
Always choose the shortest path and follow the recommendations as tabulated below:

Piping Works And Flaring Technique

Do not use contaminated or damaged copper tubing. If any

•
piping, evaporator or condenser had been exposed or had
been opened for 15 seconds or more, the system must be
vacuumed. Generally, do not remove plastic, rubber plugs
and brass nuts from the valves, fittings, tubings and coils
until it is ready for connection.

If any brazing work is required, ensure that the nitrogen

•
gas is passed through piping and joints while the brazing
work is being done. This will eliminate soot formation on
the inside walls of the copper tubings.

Cut the pipe stage by stage, advancing the blade of pipe

•
cutter slowly. Extra force and deep cut will cause more
distortion of pipe and therefore extra burr. See Figure I.

Remove burrs from cut edges of pipes with a remover

•
as shown in Figure II. This will avoid unevenness on the
flare faces which will cause gas leak. Hold the pipe on top
position and burr remover at lower position to prevent metal
chips from entering the pipe.

Insert the flare nuts mounted on the connection parts of both

•
indoor and outdoor unit, into the copper pipes.

•

The exact length of pipe protruding from the face of the swaging
block is determined by the flaring tool. See Figure III.

•

Fix the pipe firmly on the swaging block. Match the centers
of both the flare die and the flaring punch, and tighten
flaring punch fully.

Piping Connection To The Units

•

Align the center of the piping and sufficiently tighten the
flare nut with fingers. See Figure IV.

•

Finally, tighten the flare nut with torque wrench until the
wrench clicks.

•

When tightening the flare nut with the torque wrench,
ensure that the direction for tightening follows the arrow
on the wrench.

•

The refrigerant pipe connection are insulated by closed
cell polyurethane.

All wires must be fi rmly connected.

•
Make sure all the wire do not touch the refrigerant pipings, compressor or any moving parts.

•
The connecting wire between the indoor unit and the outdoor unit must be clamped by using provided cord anchorage.

•
The power supply cord must be equivalent to H07RN-F which is the minimum requirement.

•
Make sure no external pressure is applied to the terminal connectors and wires.

•
Make sure all the covers are properly fi xed to avoid any gap.

•
Use round crimp-style terminal for connecting wires to the power supply terminal block. Connect the wires by matching

•
to the indication on terminal block. (Refer to the wiring diagram attached on the unit).

Attach insulation sleeve

SPECIAL PRECAUTIONS WHEN DEALING WITH R407C UNIT

R407C is a zeotropic refrigerant mixture which has zero ozone depletion potential and thus conformed to the Montreal

•

Protocol regulation. It requires Polyol ester oil (POE) oil for its compressor’s lubricant. Its refrigerant capacity and
performance are about the same as the refrigerant R22.

POE or PVE oil is used as lubricant for R407C compressor, which is different from the mineral oil used for R22 compressor.

•

During installation or servicing, extra precaution must be taken not to expose the R407C system too long to moist air.
Residual POE or PVE oil in the piping and components can absorb moisture from the air.

Refrigerant R407C is more easily affected by dust of moisture compared with R22, make sure to temporarily cover the

•

ends of the tubing prior to installation.
No additional charge of compressor oil is permitted.

•

No other refrigerant other than R407C.

•

Tools specifically for R407C only (must not be used for R22 or other refrigerant)

•

Manifold gauge and charging hose

i)

Gas leak detector

ii)

Refrigerant cylinder/charging cylinder

iii)

Vacuum pump c/w adapter

iv)

Flare tools

v)

Refrigerant recovery machine

vi)

Filter-dryer must be installed along the liquid line for all R407C air conditioners. This is to minimise the contamination of

•

moisture and dirt in the refrigerant system. Filter-dryer must be of molecular sieve type. For a heat-pump system, install
a two-way flow filter dryer along the liquid line.

1-18

VACUUMING AND CHARGING

Vacuuming is necessary to eliminate all moisture and air from the system. The series II Outdoor Unit is provided with flare
valve fittings.

Vacuuming The Piping And The Indoor Unit

Except for the outdoor unit which is pre-charged with
refrigerant, the indoor unit and the refrigerant connection
pipes must be air-purged because the air containing moisture
that remains in the refrigerant cycle may cause malfunction
of the compressor.

Remove the caps from the valve and the service port.

•
Connect the center of the charging gauge to the vacuum

•
pump.
Connect the charging gauge to the service port of the 3-way

•
valve.
Start the vacuum pump. Evacuate for approximately 30

•
minutes. The evacuation time varies with different vacuum
pump capacity. Confirm that the charging gauge needle has
moved towards -760mmHg.

Caution

If the gauge needle does not move to -760mmHg, be sure to

•
check for gas leaks (using the refrigerant detector) at flare
type connection of the indoor and outdoor unit and repair
the leak before proceeding to the next step.
Close the valve of the changing gauge and stop the vacuum

•
pump.
On the outdoor unit, open the suction valve (3 way) and

•
liquid valve (2 way) (in anti-clockwise direction) with 4mm
key for hexagon sacked screw.

Connect the low pressure side of the charging gauge to the

•
suction service port center of the cylinder tank and close
the high pressure side of the gauge. Purge the air from the
service hose.
Start the air conditioner unit.

•
Open the gas cylinder and low pressure charging valve.

! CAUTION

R407C must be charged as liquid. Usually R407C cylinder is equipped with a dip-pipe for liquid withdrawal. If there

•
is no dip-pipe, the cylinder should be inverted so as to withdraw liquid R407C from the valve.
Do not top-up when servicing leak, as this will reduce the unit performance. Vacuum the unit thoroughly and then

•
charge the unit with fresh R407C according to the amount recommended in the specifi cation.

1-19

ADDITIONAL CHARGE

The refrigerant is pre-charge in the outdoor unit. If the piping length is less than 7.5m, then additional charge after vacuuming
is not necessary. When the piping length is more than 7.5m, use the table below.

R22 R407C

Liquid pipe OD Additional charge kg/m Additional charge kg/m

3/8" 0.06 0.05

1/2" 0.10 0.10

5/8" 0.16 0.15

3/4" 0.25 0.23

NOTE

The additional refrigerant charge amount recommended is a guideline for long piping application.
The actual charge required may be different from the guideline due to different application and variation in site conditions.

SPECIAL PRECAUTIONS WHEN CHARGING UNIT WITH SCROLL COMPRESSORS

These precautions are intended for use with Scroll compressors only with R22 and R407C refrigerants but are not applied to
others competitive Scroll compressors.

Scroll compressors have a very high volumetric efficiency and quickly pump a deep vacuum if there is insufficient refrigerant
in the system or if refrigerant is added too slowly. Operation with low suction pressure will quickly lead to very high discharge
temperatures. While this process is happening, the scrolls are not being well lubricated – scrolls depend on the oil mist in the
refrigerant for lubrication. A lack of lubrication leads to high friction between the scroll flanks and tips and generates additional
heat. The combination of heat of compression and heat from increased friction is concentrated in a small localized discharge
area where temperatures can quickly rise to more than 300°C. These extreme temperatures damage the Scroll spirals and the
orbiting Scroll bearing. This damage can occur in less than one minute especially on larger compressors. Failure may occur
in the first few hours or the damage done during field charging may show up some time later. Other typical field charging
problems include undercharging, overcharging, moisture or air in the system etc. In time each one of these problems can
cause compressor failure.

Minimal equipment is required for field charging. The minimum equipment required to do a satisfactory job is:-

4.

1.

Set of service gauges

2.

Hoses

3.

Vacuum pump

The proper refrigerant charge should follow the volume as recommended by manufacturer and recommendation should be
followed by the installer.

Charging procedures – Single phase compressors

1.

Evacuate the system to -760mmHg. To reduce evacuation time, use short, large diameter hoses and connect to unrestricted
service ports on the system. Quality of vacuum cannot be determined by time – a reliable vacuum gauge must be used.
(etc. electronic vacuum gauge)

Turn the refrigerant cylinder upside down, purge the charging hose and charge liquid through the liquid line charging port
until refrigerant no longer flows or until the correct charge has been weighed in. If additional charge is required start the
system and slowly bleed liquid into the suction side until the system is full.

It recommends charging liquid in a CONTROLLED manner into the suction side until the system is full.
This recommendation does not hold true for reciprocating compressors where liquid charging into the suction side could

cause severe damage.
Carefully monitor the suction and discharge pressures – ensure that the suction pressure does not fall below 25 psig

(1.7 bar) at any time during the charging process.

Charging procedures – Three phase compressors

The fundamental procedure is the same as for single phase models but the compressor can run in the wrong direction on
starting. If this happens reverse any two phases and start again. Short term reverse rotation will not damage the compressor.
All Specter compressors have internal discharge temperature protectors which are very effective in preventing dangerously
high discharge temperatures during charging. The protection module will trip and lock the compressor out for 30 minutes. It
is not normally necessary to wait 30 minutes for the module to reset. When the compressor has cooled down the module can
be reset by breaking the power supply to the control circuit. Very often the serviceman does not understand why the module
tripped and uses a jumper wire to bypass it. He continues to charge the system and removes the jumper when charging is
complete. The compressor may or may not run with the protector back in the circuit but it is certain that the compressor
has been damaged and premature failure is inevitable.

PHASE PROTECTOR (OPTIONAL)

The unit with Scroll Compressor can only rotate in one direction. For this reason, a protective device (phase protector) is fitted
to prevent incorrect wiring of the electrical phases. When the three phases are not connected correctly, the phase sequencer
operates, and the unit will not start. This device is located in the control box of the outdoor unit.
