uct data submittal)
• chiller certified prints
• starting equipment details and wiring diagrams
• diagrams and instructions for special controls or options
• 23XRV Installation Instructions
• 23XRV Start-up, Operations and Maintenance Instructions
• pumpout unit instructions

Equipment Required

• T30 hexalobular socket screw driver to remove control
center door shipping brackets
• mechanic's tools (refrigeration)
• digital volt-ohmmeter (DVM)
• clamp-on ammeter
• electronic leak detector
• absolute pressure manometer
• 500-v insulation tester (megohmmeter) for compressor
motors with nameplate voltage of 600 v or less

Remove Shipping Packaging

Remove any packaging material from the unit and starter.

Open Oil Circuit Valves

Check to ensure the oil filter isolation valves (Fig. 13) are open by
removing the valve cap and checking the valve stem.

Oil Charge

The oil charge for the 23XRV chiller is split between the cooler
and the oil vaporizer:

The chiller is shipped with its oil charge. The oil level in the va-
porizer will initially be in the center of the oil sump sight glass.
This level will vary depending on the amount of refrigerant that
has been absorbed by the oil and the operating conditions of the
chiller. Normal oil levels will vary from the top of the strainer
housing sight glass to above the top of the oil sump sight glass.
If oil is added, it must conform to Carrier's specification for screw
compressor use as described in the Oil Specification section.
Charge the oil through the oil charging valve located near the bot-
tom of the oil strainer housing. The oil must be pumped from the
oil container through the charging valve due to the higher refriger-
ant pressure. The pumping device must be able to lift from 0 to
200 psig (1379 kPa) or above unit pressure. Oil should only be
charged or removed when the chiller is shut down.

Tighten All Gasketed Joints

Gaskets normally relax by the time the chiller arrives at the job-
site. Tighten all gasketed joints to ensure a leak-tight chiller. See
Tables 4 and 5 for waterbox torque specifications.
