3.2.4 Provide machine protection
Protect machine from construction dirt and moisture. Keep protective shipping covers in place until machine is
ready for installation. Do not keep the 19DV units outside where they are exposed to the weather.
If machine is exposed to freezing temperatures after water circuits have been installed, open waterbox drains and
remove all water from cooler and condenser. Leave drains open until system is filled.
It is important to properly plan before installing a 19DV unit to ensure that the environmental and operating
conditions are satisfactory and the machine is protected. The installation must comply with all requirements in this
document and in the certified prints.
3.2.5 Operating Environment
Chiller should be installed in an indoor environment where the ambient temperature is between 5 and 40°C with a
relative humidity of 95% or less, non-condensing. To ensure that electrical components operate properly, do not
locate the chiller in an area exposed to dust, dirt, corrosive fumes, or excessive heat and humidity.
3.3 Step 2 – Rig the machine
The 19DV machine can be rigged as an entire assembly. It also has connections that allow the compressor,
evaporator, condenser, VFD, an major accessories be separated for plant introduction under the supervision of
Carrier. Contact local Carrier office for details if separation is required.
3.3.1 - Rigging the complete machine
See rigging instructions on label attached to machine. Lift machine only from the points indicated in the
instructions supplied and in the machine rigging drawings. Each lifting cable or chain must be capable of
supporting the entire weight of the machine.
WARNING: Lifting machine from points other than those specified may result in serious damage to the unit and
personal injury. Rigging equipment and procedures must be adequate for machine weight. See table 2 for the
machine weights.
If the unit is disassembled for slinging, the weight of each element of the machine must be known: motor,
compressor, heat exchangers with and without refrigerant charge, electrical equipment, special water boxes, etc.
This information is available on the dimensional drawing supplied with the machine.
IMPORTANT: Only a qualified service technician should perform this operation.
WARNING: Do not attempt to disconnect flanges while the machine is under pressure. Failure to relieve pressure
can result in personal injury or damage to the unit.
CAUTION: Before rigging the compressor, disconnect all wires entering the control box.
IMPORTANT: Verify with company performing the rigging that they have access to required spreader beam for 4
point lift. Carrier is not responsible for rigging damage.
CAUTION: Factory-supplied insulation is not flammable but can be damaged by welding sparks and open flame.
Protect insulation with a wet canvas cover.
Each lifting cable or chain must be capable of supporting the entire weight of the machine.
Contractors are not authorized to disassemble any part of the chiller without Carrier’s supervision. Any request
otherwise must be approved in writing by the Carrier Technical Service Manager. Non-conformance to this
requirement may result in loss of product warranty.
NOTE: Carrier suggests that a structural engineer be consulted if transmission of vibrations from mechanical
equipment is of concern and is not the responsibility of the manufacturer.
Lifting chiller or components from points other than those specified may result in serious damage to the machine
or personal injury. Rigging equipment and procedures must be adequate for maximum chiller weight.
