Part No. 1TB1047 1 CREV
SAFETY
Failure to follow these instructions could result in
equipment damage, serious personal injury or death, .
• WARNING: ELECTRIC SHOCK HAZARD! Do not operate
compressor or provide electric power to it unless the
cover is in place and secured.
•
WARNING: Do not provide power to unit or turn-on compressor
unless suction and discharge service valves are open.
•
WARNING: ELECTRIC SHOCK HAZARD! Do not remove the
compressor terminal box cover until all electrical sources
have been disconnected.
•
WARNING: CONTENTS UNDER PRESSURE! Compressor
contains oil and refrigerant under pressure. Pressure
must be relieved before installation, servicing or opening
any connections.
•
WARNING: RISK OF PERSONAL INJURY! HOT and COLD
surface temperatures can occur during operation and can
result in severe burns or frostbite.
•
WARNING: RISK OF PERSONAL INJURY! Only approved
refrigerants and refrigeration oils m be used. ay
•
WARNING: Use nitrogen or inert gas for tightness/pressure testing.
DO NOT USE oxygen or other industrial gases.
• System strength/tightness test pressure may not exceed WARNING:
the compressor est pressure on the maximum Proof T
tag. Close shuto valves to isolate compressor if
necessary.
• WARNING: Charge only with refrigerant that conforms to AHRI
Standard 700.
• Only qualified, authorized, and appropriately trained HVAC or
refrigeration personnel, should install, commission, and maintain
this equipment.
• Use appropriate personal safety equipment where required.
Safety goggles, gloves, protective clothing, safety boots, and
hard hats should be worn where necessary .
Safety Decals
Install label 2TB0713 on inside of terminal box cover. Install label
06DA502503 on outside of terminal box cover. Install one label
06DA508142 on outside of terminal box and the other label 06DA508142
on inside of terminal box.

Application Drawings
Refer to Application Drawing 0TB0410
Approved Refrigerants
The 06N screw compressor is specically designed for use in R-134a
systems.
Approved Lubricants
The are following lubricants approved for use with 06N Series screw
compressors:
• -13, PP47-14, -32, - , Carrier Material Spec PP47 PP47 or PP47 34
Viscosity Grade 220 ISO
Note that all POE oils are very hygroscopic (will readily pick up and retain
moisture from the air). Damaging acids can form if moisture is present. Oil
should only be used from a properly sealed container.
Electrical Connections
• Compressor user must provide properly sized motor over-current
protection. Use the electrical data on drawing 0TB0659 or the
compressor nameplate to size the contactor and overload relay or circuit
breaker.
• When circuit breakers are used for motor protection, they must be
permanently marked "Special Purpose - Not For General Use" and
should indicate must trip current not exceeding 140% of compressor
rated load current.
• Motor protection system must protect against primary single-phase
failure.
• Motor over- rrent protection system must protect all three phases. cu
• An appropriate terminal box must be installed.
, with its cover installed, WARNING: Terminal box must be in place
before power can be applied.
• Connect the compressor in accordance with the Application Drawing
and the wiring diagram located on the terminal box lid.
• Power wires are to be connected to the terminal pins using ring
terminals and jam nuts.
• The compressor terminals are copper feed through pins. Torque nuts in
accordance with the Application Drawing
•
WARNING: Disturbing the factory installed nut will jeopardize the
seal integrity of the terminal pin.
• The motor temperature thermistors and a separate grounding lug
connection are located in the terminal pin area.
• The T-series compressors are approved for use with Across the Line
and Open or Closed Transition Wye-Delta starting methods.
There are two critical timing parameters associated with the open
transition Wye-Delta starting method.
Duration of the Wye connection shall be 5 to 10 seconds.
WARNING: Overheating of the motor can occur if duration is
too long.

06N Screw Compressors
Part No. 1TB1047 2 CREV
Duration of the power interruption during the transition from wye
connection to delta connection shall not exceed 0.049 second.
• ew compressors are designed to operate in one specic rotational Scr
direction. operation with reverse rotation result in damage to Any will
the compressor and possibly hazardous situations. Steps should be
taken to prevent this condition. Depending on the phase relationship of
the supplied power, the motor can start and run in either direction.
Improper rotation will cause the compressor to seize and the motor will
overheat.
Verication of proper rotation can be accomplished by temporarily
installing a suitable pressure switch located before the discharge check
valve. The switch is to be wired so that it will open the compressor
control circuit if the pressure falls below 50 mm Hg (2 inches) of
vacuum, indicating reversed rotation. The switch must be a manual
reset type that can be reset after the pressure has once again risen
above 1.7 bar (25 psig ).
To correct the rotation, disconnect the power and then switch any two
power leads.
Oil System Requirements
Oil is required to lubricate the bearings and provide a seal between the
screw rotors and their bores. System pressure is used to generate the oil
pressure in normal operation but is supplemented with an oil pump during
start-up and situations with low system pressure dierential. Oil pressure
is to be monitored continuously during compressor operation. The oil
pressure, P
O
, must meet two set points based on discharge, suction and
economizer pressure (P
D,
P
S
, and P
E
respectively) as shown in Table 1
below and referenced in the oil system schematic shown in Figure 1.
Table 1 – Oil Pressure Limits
Figure 1 – Oil System Schematic
Table 1 shows the oil pressure limits base on the operating time “T” in
seconds, where zero equals compressor start. The unit control system
must monitor the oil pressure dierential, as well as the operating condition
so that the compressor can be shut down if the minimum requirements are
not met for a duration exceeding 15 seconds.
Oil system capacity depends on unit and circuit where the compressor the
is being installed. Most applications run between 4.5 and 8 gallons (17- 30
Liters). Refer to 30GX, 30HXA, 30HXC Controls Start-Up, Carrier’s
Operation Service and Troubleshooting for proper oil charge.
