A Important safety information and instructions – retain for future use.
Kirby is very safety conscious when designing and manufacturing these products, but it is
essential that the end user, installer or service personnel also exercise care when working with
or on the unit.
Warning
This indicates contents for which the possibility of human death or severe injury
in case of handling under disregard of this indication can be assumed.
Caution
This indicates contents for which the possibility of human injury or the
possibility of material damage in case of handling under disregard of this

The Condenser unit:
Moving Machinery
KRC Units have components that may start up automatically. The KRC must have all electrical
items isolated before any service or repairs are carried out.
No Smoking
Kirby recommends No Smoking within a distance of 15 metres of the KRC Unit.
Warning – Electrical Hazard
A qualified Electrician must carry out all electrical work.
Always isolate the power to the KRC before checking, diagnosing, removing and replacing the
fan assembly units. Never work on any electrical item without isolating or disconnecting the
power supply.
Caution – Unit Pressurised
In the manufacturing of this product it is essential to pressurize and test the KRC. This unit may
have some pressure within. Please take care when unsealing the unit to fit the pipe and line
connections.
Caution – Refrigerant Type
The Condenser is designed to work effectively using fluorocarbon refrigerants. Under no
circumstances can Ammonia based gas, Hydrocarbon based gas, or CO2 gas, be used in this
product.
Refrigerant type: HCFC and HFC (refer to “Standard Conditions” for approved fluorocarbon
refrigerants)
For Water and Glycol applications please refer to your Kirby technical representative.
Caution – Sharp Edges

The Condenser is manufactured with sheet metal and in this process all care is taken to ensure
the edges are concealed. In some circumstances this cannot occur. Please take care when
accessing in or around the KRC.
Warning – Qualified Personnel
Condenser’s may only be installed, commissioned and serviced by qualified and trained
personnel .
Personal Protective Equipment
Kirby recommends as a secondary safety precaution that all personnel working in and around
the Condenser wear appropriate Personal Protective Equipment (PPE).
Lifting & Installation Precautions

PURPOSE-
KRC remote condensers are standard OEM products of Kirby. They are intended to provide for
the condensation of fluorocarbon refrigerant for typical commercial sized refrigeration
applications, and are suitable for use in indoor or outdoor environments. They are not intended
for environments that may have harmful, corrosive or flammable atmospheres. ‘Marine’
environments are considered corrosive; please consult Kirby before installing in this
environment.
Standard Design Conditions
KRCxxx-xPH condensers are designed to operate with a maximum operating pressure of
3650kPag, with a maximum KTD of 20K, and a minimum of 5K (please refer to the relevant
technical data literature for more specific recommendations). Special circuiting may be needed
to achieve specific conditions outside of these limits- please refer to your Kirby representative.
Motors must NOT be subject to air-over-motor temperatures greater than allowed by the fan
manufacturer(s). Please refer to the relevant technical literature.
APPROVED REFRIGERANTS-
R404A/R448A/R449A/R134a/R513A/R450A and R410A are approved for use in all
KRCxxx-xPH models.
For more details, please refer to the relevant technical literature.
MAXIMUM WORKING PRESSURE-
KRCxxx-xPH models have a maximum working pressure of 3650kPag.
KRCxxx-xxH condensers cannot use Ammonia (NH3, R717), Carbon dioxide (R744), or
hydrocarbons, as refrigerant.
For special design requirements such as non standard conditions and/or fluid coolers (Glycol,
oil, etc), please inquire with your local representatives and/or Kirby local branches

Warning Electrical 415Volt ±

A qualified Electrician must carry out all electrical work.
For general wiring please refer page 15 to 21 for details.
Refer model number for corresponding “CL” drawing.
MOTORS WITH THERMAL OVERLOAD PROTECTION-
KRC remote condenser fans are all equipped with thermal overload motor protection.
Warning- Non-running fans may restart unexpectedly if the overload has been activated. Do
not assume a fan that is not running has been disconnected from the power supply. Always
check for the presence of live voltage before removing the junction box lid and/or performing
any work on the fans.
MOTORS WITH EXTERNALLY WIRED OVERLOADS-
350mm diameter single phase fans are equipped with internally wired overloads, which cut the
power supply to the motor directly.
500mm and 630mm single (and optional three phase) fans are equipped with externally wired
overloads. These overloads will only control power to the motor when wired in to an external
control circuit.
The wiring required depends on how many fans are present and whether the unit is a single or
twin coil model. Please refer to the following wiring schematic diagrams for details.
Failure to wire the externally connected overloads in a suitable manner may lead to
unnecessary failure of the motor and voiding of the unit warranty.
PLEASE REFER TO THE SERIAL PLATE OF THE CONDENSER AND/OR FANS TO
DETERMINE THE POWER SUPPLY OF THE FANS ON THE SUPPLIED UNIT, AND REFER
TO THE APPROPRIATE DIAGRAMS ON THE FOLLOWING PAGES.
FAN SPEED CONTROL-
Single and three phase AC fans may be controlled using a voltage reducing fan speed control
based on pressure sensing. Due to the large variety of controls available, only a few general
observations can be made.
Settings- Refer to the Recommended control settings on p14 for FVS setpoints, other settings
will be dependent on the individual controller selected.
Minimum voltage-
Fan manufacturers data should be referred to, however in general-
1 Ph- 130V (all fan types).
3 Ph- 230V (all fan types)

EC FANS-
EC fans are available on KRC condensers under the KP606- series options kits for 350mm,
500mm, and 630mm fan sizes.
The fans are 0-10V controlled, using a Saginaomiya XGE-4SE controller and high pressure
transducer mounted on the gas header.
Please refer to Technical Bulletin TB146 for details of the controller.
EC fans have built-in overload protection. If an EC fan does not start, please check the
temperature and allow to cool before diagnosing a faulty fan. The circumstances of the cut-out
should be investigated.

Recommended control settings-
The Saginomiya control MUST NOT be used with R410A refrigerant.
Condenser must be sized to prevent pressure exceeding the design pressure, and the air over
motor temperature from exceeding the allowable value. Refer to technical literature CL250 and
CL287 for details.
