Installation
If pressure is higher than 60mbar, a presure reducer must
be installed at a distance of at least 10m and no pressure
stabiliser must be fitted between the pressure reducer and
the heater, but leaving the gas filter.
Max 60 mbar
During the installation, we recommend to tighten the nut
fastening the external gas supply pipe without exceeding the
tightening torques shown below:
- Ø 3/4'': 150 Nm;
Smoke outlet features
Unit is shipped with an outlet adaptor for connection to
exhaust pipe. If there is no exhaust pipe used, a terminal
feature located on the accessories should be installed.
Note: Exhaust pipe material has to be chosen carefully
to avoid corrosion.

General Electrical Recommendations
Electrical Parts
When reviewing this manual keep in mind.
- All field-installed wiring must be in accordance with
local regulations, CE directives and guidelines. Be sure
to satisfy proper equipment grounding requirements
according CE
- The following standardized values - Maximum Amps -
Short Circuit Amps - Starting Amps are displayed on
unit nameplate.
- All field-installed wiring must be checked for proper
terminations, and for possible shorts or grounds.
Note: always refer to wiring diagrams shipped with unit
or unit submittal for specific electrical schematic and
connection information.

WARNING Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
Important!
Do not allow conduit to interfere with other
components, structural members or equipment. Control
voltage (230 V) wiring in conduit must be separate from
conduit carrying low voltage (<30V) wiring. To prevent
control malfunctions, do not run low voltage wiring
(<30V) in conduit with conductors carrying more than 30
volts.
CAUTION!
Inverters are equipped with integrated filters.
They are not compatible with insulated neutral load
earthing arrangements.
WARNING! Hazardous Voltage with Capacitor!
Disconnect all electric power, including remote
disconnects and discharge all motor start/run and
AFD (Adaptive Frequency TM Drive) capacitors before
servicing. Follow proper lockout/tagout procedures to
ensure the power cannot be inadvertently energized.
Any contact with electric components, even after the
unit has been switched off, can cause serious injury or
death. Wait at least 5 minutes after switching off the
unit, until the current dissipates.
•
For variable frequency drives or other energy
storing components provided by Trane or others,
refer to the appropriate manufacturer's literature for
allowable waiting periods for discharges capacitors.
Verify with an appropriate voltmeter that all
capacitors have discharged.
•
DC bus capacitors retain hazardous voltages
after input power has been disconnected. Follow
proper lockout/ tagout procedures to ensure the
power cannot be inadvertently energized After
disconnecting input power, wait five (5) minutes
for units which are equipped with EC fans and wait
twenty (20) minutes for units which are equipped
with variable frequency drive (0V DC) before
touching any internal components. Failure to follow
these instructions could result death or serious
injury.
Installer-Supplied Components
Customer wiring interface connections are shown in the
electrical schematics and connection diagrams that are
shipped with the unit. The installer must provide the
following components if not ordered ith the unit:
• Power supply wiring (in conduit) for all field-wired
connections.
• All control (interconnecting) wiring (in conduit) for
field supplied devices.
• Circuit breakers.
