This manual provides installation, operation, and maintenance information for the Daikin TGZ Templier
®
Heat Recovery Scroll
Water Heater with the MicroTech
®
II controller. Complete operating and maintenance information is in OMM 1136.
NOTE: Installation and maintenance are to be performed only by qualied personnel who are familiar with local codes and
regulations, and experienced with this type of equpuipment.
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 TGZ water heaters are scroll compressor refrigeration units that recover heat from warm uid streams in the evaporator and
deliver hot water, at a useful temperature, from the condenser to a heating load. They are designed for indoor installations only and
are completely assembled, wired, charged and tested. Each unit consists of four or six (depending on unit size) scroll compressors,
evaporator (brazed-plate on models 040 through 120 and shell-and-tube evaporators on models 150 to 190), shell-and-tube
condenser/heater, and complete refrigerant piping.
There are two refrigerant circuits, each with manual liquid line shutoff valves, charging valves, lter-driers, liquid line solenoid
valves, sight glass/moisture indicators, and expansion valves. The electrical control center includes a MicroTech II® control system
and other components necessary for dependable automatic operation.
