Introduction
TT series compressors are totally oil-free and
optimized for use with refrigerants R134a and
R513A.
TG series compressors are totally oil-free and
optimized for use with refrigerant R1234ze only.
ASHRAE standard 34 has classified this refrigerant
as “R1234ze(E) with safety classification of A2L.”
ASHRAE Standard 34, 2010 Addendum 1 contains
the change to the standard.
ASHRAE Standard 15 (Safety Standard) has sent
out an initial public review document outlining
proposed changes to this standard to address 2L
refrigerant.

NOTE
Do not use recycled refrigerant as it may contain oil, which can affect system reliability. The refrigerant should be pure and stored
in virgin containers.
NOTE
The Mains Input fast-acting fuses are installed in the power panel for all compressor models except the TT300/TG230.
Before performing any service on the compressor,
electrical power must be isolated.
Before removing top side covers, isolate the
compressor power by completing the following
steps:
1. Turn off the Mains Input power to the
compressor.
2. Lock Out/Tag Out (LOTO) the mains disconnect
to ensure no accidental or unauthorized re-
application of the Mains Input power can occur.
3. Remove the Mains Cover only.
4. Using an appropriately rated voltage meter,
confirm that the AC voltage is isolated.
1.7 Electrical Isolation of
the Compressor
• • • DANGER • • •
This equipment contains hazardous voltages that can cause serious injury or death. Only qualified and trained personnel should
work on DTC compressors.
• • • DANGER • • •
Always wear appropriately rated safety equipment when working around equipment and/or components energized with high
voltage.
• • • DANGER • • •
Removing the Mains Input Cover will expose you to a high voltage hazard of up to 632VAC. Ensure the Mains Input power is
turned off and locked out before removing it.
• • • DANGER • • •
Do not touch any components when removing the Mains Input Cover. This is particularly true for compressors with CE covers
because they are coated on the inside for the express purpose of being conductive.
