Unit mounting
The 5–20 ton models are shipped as a fully assembled integral package. The 25-ton model ships
factory split with nitrogen holding charge only. Factory provided couplings are included for field
assembly of the 25-ton model.
If required, units may be field split to allow for passage through doors, elevators, hallways, etc.
Duct flanges for evaporator return are incorporated into the filter rack.
Units should be secured on a solid, level pad or sturdy stand. The use of an isolating rubber
sheet is recommended to reduce vibration and noise transmission. Ensure that the entire base is
continuously supported;
DO NOT SUPPORT UNIT AT CORNER POINTS ONLY!
Unit may be pitched
slightly to ensure efficient drainage of condensate.
Blower section/condenser separation (CSV060B–CSV180B
models)
The 5–15 ton models allow for easy removal of the blower section:
•
Disconnect the evaporator motor high voltage wires. Pull all wiring into the evaporator
compartment. Remove bushing/clamp from routing hole for evaporator motor wiring.
•
Remove corner securing brackets from the outside corners of the cabinet, at the joint line
between the blower and evaporator sections.
•
Remove the blower section.
Evaporator/condenser separation (CSV240B model)
The 20-ton model requires the evaporator to be separated from the condenser:
•
Reclaim the entire refrigerant charge from each compressor circuit.
•
Disconnect the evaporator motor high voltage wires. Pull all wiring into the evaporator
compartment. Remove bushing/clamp from routing hole for evaporator motor wiring.
•
Cut and remove sections of all liquid and suction refrigerant lines. Units with optional Hot Gas
Bypass will also require to be cut. Make two cuts in each line, approximately 6 inches above
and below the evaporator floor/condenser roof.
CAUTION
Use a TUBING CUTTER ONLY; do not use a hacksaw to cut refrigerant tubing, otherwise serious damage
can occur to refrigeration system!
•
Remove corner securing brackets from the outside corners of the cabinet at the joint line
between the evaporator and condenser sections.
•
Remove the evaporator section.
Assembly of split units (CSV240B–CSV300B models)
The 25-ton model comes factory split and includes copper pipe couplings for assembly. Corner
brackets are shipped inside the unit.
•
Place the condenser section in the required location.
