3.7 — Refrigerants and Oils for 06CC Compressors

All 06CC compressors are approved for R-22, R-404A

and R-507 except compressors in the 16 to 37 Cfm

range. Compressors in this size range cannot be used

with R-404A and R-507 prior to Serial No. 2099J ----

without installing a retrofit compressor valveplate (Part

No. 06CY660-002) kit. See Section 3.6 on page 69 for

further information about refrigerants and oils.

See Section 3.6 on page 71 for the correct oil for each

refrigerant. Contact Carlyle Engineering for correct oil

for R-23 and R-508A (SUVA 95).

3.8 — Oil and Refrigerant Change-Out Procedures

To change from a CFC or HCFC to either an HFC or an

HCFC blend, follow the refrigerant and oil manufacturer

installation procedures. Select a Carlyle approved

refrigerant and appropriate oil as noted in Sections 3.6

and 3.7 above. System cleanliness is extremely impor-

tant. To ensure a trouble-free change out, Carlyle

Engineering has made specific guidelines available. We

strongly recommend a copy of our guidelines be re-

quested and procedures carefully followed to avoid

problems.

3.9 — Oil Viscosity and Pour Points

The viscosity of oils used in Carlyle reciprocating

compressors is ISO 68 (centistoke) for all POE oils and

150 Saybolt Seconds Universal (150 SSU or 150 SUS)

or ISO 32 for mineral and alkylbenzene oils. Using oil

with a different viscosity without approval from the

Carlyle Engineering Department will void the warranty.

The oils listed in Sections 3.6 and 3.7 and the viscosity

listed above can be used down to -40°F (-40°C). If your

system runs at a lower temperature, please contact

Carlyle Engineering for an oil recommendation.
