Summary of Control Points
Oil System:
Maximum oil temperature entering compressor:
•
06T models: 190°F (88°C)
•
05T models: 180°F (82°C)
Minimum oil temperature entering compressor:
•
80°F (27°C)
Oil Filter Pressure Drop Protection (discharge pressure mi-
nus oil pressure):
•
Cutout: 45 psi (3 Bar)
•
Alarm: 25 psi (1.6 Bar)
Minimum oil pressure differential (oil inlet pressure to suction
pressure)
•
Cutout: 45 Psi (3 Bar)
(Must be measured for each compressor)
Floating Head Pressure:
Oil pressure at the compressor must be a minimum of
45 psi (3 bar) above suction pressure. To maintain this, the
discharge pressure must be maintained at this 45 psi (3 bar)
plus the pressure drop in the oil filters plus any flow losses
in the oil supply piping.
1.0 General Information
1.1 Certification
The 06T compressors are UL listed under file number is
SA4936. CSA file number is LR29937; CSA report number
is LR29937-579c. For UL and CSA approvals it is essential
that the overcurrent protection follow the guidelines speci-
fied in Section 5.2 of this guide. Both UL and CSA approvals
have been obtained for all voltage combinations listed in
Section 5.3. 60 Hz compressors have been listed.

Motor Temperature Control:
LonCEM protection
Carlyle recommends liquid injection to mitigate motor tem-
peratures above
180°F (82°C). The compressor must shut-
down with motor temperatures exceed 240°F (116°C).
Discharge Temperature Control:
LonCEM protection or
Carlyle recommends liquid injection to mitigate discharge
temperatures above
205°F (96°C). The compressor must
shutdown with discharge temperatures exceed 230°F
(110°C).
Reverse Rotation Protection:
LonCEM protection or
Manual reset low pressure switch connected to discharge
port and set at 10 inches of vacuum, (0.33 bar). This pres-
sure switch is intended only for commissioning and should
be removed from the system prior to long term operation.
or
Carlyle Approved Line/Load Phase Monitor
Semi-hermetic compressors will be supplied with single
voltage motors 208/230 volts, 460 volts and 575 volts.
1.3 Compressor Mounting
The Carlyle 05T/06T screw compressors may be rigid
mounted. However, Carlyle recommends the use of isola-
tion mounts for 06T compressors. These rubber mounts iso-
late the compressor from the system framework which
helps to reduce noise transmission.
1.4 Oil Type
Carlyle screw compressors are approved for use on
R-448A, R-449A, R-404A, R-507, R-134a, and R-22
with the following oils:
Oil
Solest 120
Solest 170
Emkarate RL100E
For application purposes the Solest 120 is considered an
equivalent viscosity at the Emkarate RL100E. The Solest
170 is required for R-22 systems without external oil
coolers. R-22 systems with an external oil cooler may use
the POE 100/120 weight oils.
