Step 3 - Install Machine Supports; Install Standard Isolation; Installation Of Levelling Accessory (If Necessary) - Carrier 19DV Series Installation, Operation And Maintenance Instructions

6. Cut bearing supply tubing from lube assembly.
7. Cut motor cooling supply line tubing from high side float chamber.
8. Disconnect inhibitor reclaim line running from compressor to near bottom of evaporator.
9. Disconnect all power and control wires connected to the compressor.
10. Cover all openings
11. Disconnect compressor motor power cables from VFD to motor.
12. Unbolt compressor mounting from the evaporator.
Additional Notes
1. Use silicone grease on new O-rings when refitting.
2. Use gasket sealant on new gaskets when refitting.
3.4 Step 3 – Install Machine Supports
Typical applications of these units are in refrigeration systems, and they do not require earthquake resistance.
Earthquake resistance has not been verified.

3.4.1 Install standard isolation

Figure X shows the position of support plates and shear flex pads, which together form the standard machine
support system.
Note: the isolation package includes four shear flex pads.
1.Support plate
2.Shear flex pad
: Machine foot
Fig 17 – Standard isolation
Important: Chiller housekeeping pad, anchor bolts, and attachment points that are designed by others must be in
accordance with all applicable national and local codes.

3.4.2 Installation of levelling accessory (if necessary)

Uneven floors or other considerations may dictate the use of accessory soleplates (supplied by Carrier for field
installation) and leveling pads. Refer to Fig 18.
Chiller support plates must be level within 1/4-in. (6 mm) from one end to the other.
Level machine by using jacking screws in isolation soleplates. Use a level at least 24-in. (600 mm) long.
For adequate and long lasting machine support, proper grout selection and placement is essential. Carrier
recommends that only pre-mixed, epoxy type, non-shrinking grout be used for machine installation.
Follow manufacturer's instructions in applying grout.
1. Check machine location prints for required grout thickness.
2. Carefully wax jacking screws for easy removal from grout.
3. Grout must extend above the base of the soleplate and there must be no voids in grout beneath the plates.
4. Allow grout to set and harden, per manufacturer's instructions, before starting machine.
5. Remove jacking screws from leveling pads after grout has hardened.
