Installation

With the 
hubs mount-
ed and the 

axial spacing 

set, proceed 
to place 
the spacer 
between 
the two hub 

flanges. Take 

care when 

handling 

the spacer. 
Be sure the 

spacer is fully supported at this time. Damage to the 
unitized flex discs may result after they have been 

installed if the spacer is not fully supported.

3.   Install  the 

unitized flex disc. Start a bolt through a bolt 

hole in the 

spacer. Put the unitized flex disc between 

the hub and spacer until a bushing hole in the unitized 
flex disc lines up with the bolt. Slide the bolt through 
the bushing hole in the unitized flex disc. To avoid 
thread damage, ensure that every other bolt is installed 

in the opposite direction as shown in the photo.

4.   Install  the 

locknut until it is snug. Make sure that all 

bolt threads are clean and lightly oiled. Do not torque 
any locknuts at this time. Now pivot the unitized flex 
disc until the other bushing holes in the flex disc are in 

line with the bolt holes in the spacer. Install the rest of 

the spacer bolts at this time. The remaining bolts for 
this end of the coupling can be installed through the 
hub bolt holes and flex disc bushing holes.

5. 

 Install the unitized flex disc in the other end of the 
coupling. Ensure the unitized flex disc, when installed, 
looks flat and parallel with the mating hub and spacer 
flanges.

6.   See 

Table 3 

for torque values for the disc pack lock-

nuts. Hold the bolts in place while the locknuts are 
torqued.

7. 

 Center the coupling between the shafts. Ensure that 
the keys are fully engaged in their keyways.

8. 

 Tighten the motor and compressor shaft clamping bolts 

evenly. See 

Table 3

 for torque values.

9.   See 

Table 3

 for torque values for the keyway set-

screws.

Notice

Only after tightening the shaft clamping bolts to 

their final torque can the keyway set screws be 

tightened. If the keyway set screws are tightened 
before the shaft clamping bolts are tightened, then 
the hubs can be cocked on the shaft.

Notice

Do not use any lubricant on these bolts.

Holding charge and storage

Each HPS compressor unit is pressure and leak tested at 

the factory and then thoroughly evacuated and charged 

with 

dry nitrogen to ensure the integrity of the unit during 

shipping and short term storage before installation.

 

Caution

Take care when entering the unit to ensure that the 
nitrogen charge is safely released.

 

 

Warning

Holding-charge shipping gauges on separator and 
external oil cooler are rated for 30 psig (2.07 bar) and 
are for checking the shipping charge only. They must 
be removed before pressure testing the system and 
before charging the system with refrigerant. Failure 
to remove these gauges may result in catastrophic 
failure of the gauge and uncontrolled release of re-
frigerant resulting in serious injury or death.

Keep units in a clean, dry location to prevent corrosion 

damage. Reasonable consideration must be given to the 

care for the solid-state components of the control panel. 

Contact Frick service for long-term storage requirements.

Compressor unit oil

 

Warning

Do not mix oils of different brands, manufacturers, or 
types. Mixing of oils may cause excessive oil foam-
ing, nuisance oil level cutouts, oil pressure loss, gas 
or oil leakage and catastrophic compressor failure.

Notice

The Frick oil charge shipped with the unit is the best 

suited lubricant for the conditions specified at the 

time of purchase. If there is any doubt due to the re-
frigerant, operating pressures, or temperatures, refer 
to Frick Oil publication 

160.802-SPC

.

Oil charge

Notice

Oil may migrate from the wet sump area to the dry 
coalescer area during transportation and handling. 
Before commissioning the compressor, check for any 
oil migration. Oil transfer may be needed.
