INTRODUCTION
The Daikin EWWP-KA packaged water-cooled water chillers are
designed for indoor installation and used for cooling and/or heating
applications. The units are available in 11 standard sizes with
nominal cooling capacities ranging from 86 to 195 kW.
The EWWP units can be combined with Daikin fan coil units or air
handling units for air conditioning purposes. They can also be used
for supplying chilled water for process cooling.
The present installation manual describes the procedures for
unpacking, installing and connecting the EWWP units.
This appliance is intended to be used by expert or trained users in
shops, in light industry and on farms, or for commercial use by lay
persons.
Sound pressure level is less than 70 dB(A).

UNPACKING AND PLACING THE UNIT
1 Cut the straps and remove the cardboard box from the unit.
2 Remove the four screws fixing the unit to the pallet.
3 Level the unit in both directions with the lifting lugs which are
delivered with the control box (ECB*MUAW).
4 Use four anchor bolts with M8 thread to fix the unit in concrete
(directly or using the floor standing supports).
IMPORTANT INFORMATION REGARDING THE
REFRIGERANT USED
This product contains fluorinated greenhouse gases covered by the
Kyoto Protocol. Do not vent gases into the atmosphere.
Refrigerant type: R407C
(1)
GWP
value: 1652.5
(1)
GWP = global warming potential
The refrigerant quantity is indicated on the unit name plate.
CHECKING THE WATER CIRCUIT
The units are equipped with water inlets and water outlets for connection to a chilled water circuit and to a hot water circuit. These circuits
must be provided by a licensed technician and must comply with all
relevant European and national regulations.
The unit is only to be used in a closed water system.
Application in an open water circuit can lead to excessive
corrosion of the water piping.
Before continuing the installation of the unit, check the following
points:
1 A circulation pump must be provided in such a way that it dis-
charges the water directly into the heat exchanger.
SELECTION OF LOCATION
The units are designed for indoor installation and should be installed
in a location that meets the following requirements:
1 The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.
2 The space around the unit is adequate for servicing.
3 There is no danger of fire due to leakage of inflammable gas.
4 Select the location of the unit in such a way that the sound
generated by the unit does not disturb anyone.
5 Ensure that water cannot cause any damage to the location in
case it drips out of the unit.
The equipment is not intended for use in a potentially explosive
atmosphere.
INSPECTING AND HANDLING THE UNIT
At delivery, the unit should be checked and any damage should be
reported immediately to the carrier claims agent.
2 A flow switch must be installed in the water outlet pipe to prevent
the unit from operating at a water flow which is too low. A
terminal is provided in the switch box for the electrical
connection of the flow switch.
3 A wire mesh strainer (<1 mm) must be installed at the pump
suction as to protect the pump and the heat exchanger from
foreign matter.
4 Drain taps must be provided at all low points of the system to
permit complete drainage of the circuit during maintenance or in
case of shut down.
5 Air vents must be provided at all high points of the system. The
vents should be located at points which are easily accessible for
servicing.
6 Shut-off valves should be provided at the unit so that normal
servicing can be accomplished without draining the system.
7 Vibration eliminators in all water piping connected to the chiller
are recommended to avoid straining the piping and transmitting
vibration and noise.

NOTE
Provide adequate safeguards in the water circuit to
make sure that the water pressure will never exceed
the maximum allowable working pressure.
PIPING INSULATION
The complete water circuit, inclusive all piping, must be insulated to
prevent condensation and reduction of the cooling capacity.
Protect the water piping against water freezing during winter period
(e.g. by using a glycol solution or heatertape).
FIELD WIRING
All field wiring and components must be installed by a
licensed electrician and must comply with relevant
European and national regulations.
The field wiring must be carried out in accordance with the
wiring diagram supplied with the unit and the instructions
given below.
Be sure to use a dedicated power circuit. Never use a
power supply shared by another appliance.
Installing the control box (ECB*MUAW)
Follow instructions in "Annex" (32~72 Hp) at the very end of this manual when installing the control box into the unit.
CONNECTING THE WATER CIRCUIT
The evaporator and condenser are foreseen of GAS male pipe thread
for the water inlet and outlet (refer to the outlook diagram).
Evaporator and condenser water connections are to be made in
accordance with the outlook diagram, respecting the water in- and
outlet.
If air, moisture or dust gets in the water circuit, problems may occur.
Therefore, always take into account the following when connecting
the water circuit:
1. Use clean pipes only.
2. Hold the pipe end downwards when removing burrs.
3. Cover the pipe end when inserting it through a wall so that no dust
and dirt enter.
WATER CHARGE, FLOW AND QUALITY
To assure proper operation of the unit a minimum water volume is
required in the system and the water flow through the evaporator
must be within the operation range as specified in the table below.

Power circuit and cable requirements
1 The electrical power supply to the unit should be arranged so
that it can be switched on or off independently of the electrical
supply to other items of the plant and equipment in general.
2 A power circuit must be provided for connection of the unit. This
circuit must be protected with the required safety devices, i.e. a
circuit breaker, a slow blow fuse on each phase and an earth
leak detector. Recommended fuses are mentioned on the wiring
diagram supplied with the unit.
Switch off the main isolator switch before making any
connections (switch off the circuit breaker, remove or
switch off the fuses).
The water pressure should not exceed the maximum
working pressure of 10 bar.

Connection of the water-cooled water chiller power supply
1 Using the appropriate cable, connect the power circuit to the N,
L1, L2 and L3 terminals of the unit.
2 Connect the earth conductor (yellow/green) to the earthing
terminal PE.

Interconnection cables
■ In addition to the power supply cable, a cable must be provided
for the connection of the flow switch.
Be sure to interlock so, that the compressor will not come into
operation unless the waterpump is operated. For this purpose 2
spare terminals are provided in the switch box. Refer to the
wiring diagram supplied with the unit.
■ Voltage free contacts
The controller is provided with some voltage free contacts to
indicate the status of the unit. These voltage free contacts can
be wired as described on the wiring diagram.
■ Remote inputs
Besides the voltage free contacts, there are also possibilities to
install remote inputs.
They can be installed as shown on the wiring diagram.
BEFORE STARTING
The unit should not be started, not even for a very short
period of time, before the following pre-commissioning
checklist is filled out completely.
