Notes: The most common problems delaying start-up and affecting unit reliability are:
1. Field installed compressor motor power supply leads too small. Questions: Contact the local Daikin Applied sales representative. State size, number and type of
conductors and conduits installed:
a. From Power supply to starter
b. From starter to chiller unit (remote mounted)
2. Centrifugal chillers with water cooled oil coolers must have a 115 volt normally closed water solenoid valve installed in the oil cooler water supply line. Daikin
Applied recommends ASCO Type 8210B27 solenoid valve or approved equal and 40-mesh strainer. Daikin Applied does not supply these components.
3. A 115-volt field-supplied relay (CP1,2) must be used to start/stop condenser water pump on most applications. Cold condenser water must not flow through
condenser during compressor off cycle. Provisions have been made in control center for connecting CP relay, but must not have a rating in excess of 100 VA.
4. Refer to NEC Article 430-22 (a) *Does Not Apply to Magnetic Bearing Chillers (WMC/WME)

This manual provides installation, operation, and maintenance information for Daikin WMC Magnitude®centrifugal chillers with the
MicroTech®II controller.
WARNING
Electric shock hazard. Improper handling of this equipment can cause personal injury or equipment damage. This equipment must
be properly grounded. Connections to and service of the MicroTech®II control panel must be performed only by personnel that are
knowledgeable in the operation of the equipment being controlled.
CAUTION
Static sensitive components. A static discharge while handling electronic circuit boards can cause damage to the components.
Discharge any static electrical charge by touching the bare metal inside the control panel before performing any service work.
Never unplug any cables, circuit board terminal blocks, or power plugs while power is applied to the panel.
CAUTION
When moving refrigerant to/from the chiller from an auxiliary tank, a grounding strap must be used. An electrical charge builds
when halo-carbon refrigerant travels in a rubber hose. A grounding strap must be used between the auxiliary refrigerant tank and
the chiller’s end sheet (earth ground), which will safely take the charge to the ground. Damage to sensitive electronic components
could occur if this procedure is not followed.

General Description
Daikin Magnitude®Centrifugal Chillers are complete, self-
contained, automatically controlled, liquid-chilling units
featuring oil-free, magnetic bearing compressors. All
Magnitude®chillers are equipped with a single evaporator and
a single condenser along with either one or two compressors
depending on the model. TMC Templier units are equipped
with centrifugal compressors and are available as a
conguration, each with optional pass arrangements.
Magnitude®chillers are designed for indoor, non-freezing
installation only. The chillers use refrigerant HFC-134a that
operates at a positive pressure over the entire operation range,
so no purge system is required.
Only normal eld connections such as water piping, relief valve
piping, electric power, and control interlocks are required,
thereby simplifying installation and increasing reliability.
Necessary equipment protection and operating controls are
included.
All Daikin Applied centrifugal chillers must be commissioned by
a factory-trained Daikin Applied service technician. Failure to
follow this startup procedure can affect the equipment warranty.
The standard limited warranty on this equipment covers parts
that prove defective in material or workmanship. Specic
details of this warranty can be found in the warranty statement
furnished with the equipment.

The Control System
The centrifugal MicroTech®II control system consists
of a human machine interface touch screen (HMI), a
microprocessor-based unit controller, and compressor on-
board controllers, providing monitoring and control functions
required for the efcient operation of the chiller.
Human Machine Interface
The human machine interface (HMI) screen, (see Figure 2
for an example of a screen display), is the primary device for
viewing unit operation information and entering commands and
entries into the control system. Select information from the HMI
panel can be downloaded via a USB port located on the side of
the touchscreen panel.
A single HMI is used per unit. The HMI panel, see Figure
1, is mounted on a moveable arm to allow placement in a
convenient position for the operator. The HMI PC is located in
the Control Panel, as shown in Figure 3. For more information
on the HMI, see “Machine Interface Screen (HMI)” on page
30.
Figure 2: Machine Interface Touch Screen
Unit Controller
The purpose of the MicroTech®II unit controller is to acquire
and process data relating to chiller operation, issue instructions
to various components of the chiller, and maintain controlled
operation of the chiller. As a part of operating the chiller
successfully, the unit controller offers necessary condenser
water control. See “Water Piping” on page 16 for more
information.
The controller is located in the control panel, as shown in
Figure 3. It has a 4x20 LCD display and keys for accessing
data and changing setpoints. The controller sends information
to the machine interface touch screen (HMI) for graphic
display. If the HMI should become inoperable, the controller
LCD can display most of the same information as the HMI and
can be used to operate the chiller independently of the HMI.
See “The Controller” on page 57 for information.
Figure 3: Control Panel
Compressor On-Board Controllers
Each compressor is equipped with microprocessor controllers
and sensors that provide control and data acquisition. The data
is transmitted to other controllers and the HMI via the multi-
unit communication network. The on-board controllers control
compressor functionality and the motor/bearing system.

Nameplates
There are several identication nameplates on the chiller:
• The unit nameplate is located on the exterior of the Unit
Control Panel. Both the Model No. and Serial No. are
located on the unit nameplate; the Serial No. is unique to
the unit. These numbers should be used to identify the
unit for service, parts, or warranty questions. This plate
also has the unit refrigerant charge and electrical ratings.
• Vessel nameplates are located on the evaporator and
condenser. They have a National Board Number (NB)
and a serial number, either of which identify the vessel
(but not the entire unit).
Receiving and Handling
The unit should be inspected immediately after receipt for
possible damage. All Daikin Applied centrifugal water chillers
are shipped FOB factory and all claims for handling and
shipping damage are the responsibility of the consignee.
On units with factory-installed insulation, the insulation
is removed from the vessel lifting hole (also used for
transportation tie-downs) locations and is shipped loose. It
should be secured in place after the unit is nally placed.
Neoprene vibration isolation pads are shipped loose in the
power panel. If the unit is equipped with a shipping skid, leave
the skid in place until the unit is in its nal position. This will aid
in handling the equipment.
CAUTION
Extreme care must be used when rigging the unit to prevent
damage to the control panels and refrigerant piping. See the
certied dimension drawings included in the job submittal for
the weights and center of gravity of the unit. If the drawings
are not available, consult the local Daikin Applied sales ofce
for assistance.
The unit can be lifted by fastening the rigging hooks to the four
corners of the unit where the rigging eyes are located — see
Figure 5. A spreader bar must be used between the rigging
lines to prevent damage to the control panels, piping, and
electrical panels. The spreader-bar length should be equal
to, or no more than 1-foot shorter than, the distance between
the lifting holes located at opposite ends of the chiller. The
unit will require a single spreader-bar of this length capable
of supporting 1.5 times the shipping weight of the unit.
Separately, all cables and hooks by themselves must also be
capable of supporting 1.5 times the shipping weight of the unit.
If a knockdown option was ordered on the unit, reference the
“Retrot Knockdown” section starting on page 9 for more
information.
