Specifications
Drawing Notes
1. Final connections must allow for 0.5 inch +/- (12.7mm)
manufacturing tolerances.
2. 1.00-inch FPT (25.4 mm) evaporator and condenser
relief valves must be piped per ANSI / ASHRAE 15.
Number of relief valves is 1 per evaporator and 2 per
condenser.
3. 0.375 inch (9 mm) suction nozzle relief valve must be
piped per ANSI / ASHRAE 15.
4. Minimum Clearances (See Figure 6):
• Installation layout should be designed by qualied
personnel familiar with local codes.
• Allow a minimum of 3 ft. on all for sides and the top
sides of chiller to allow for service access.
• Provide a minimum of 3 ft. clearance in front of chiller
starter panel or according to NEC or local codes.
• Provide a minimum of 12 ft. clearance on one end of
chiller models WMC145S, 145D, and 250D for tube
removal.
• Provide a minimum of 15 ft clearance on one end of
chiller models WMC150D, 290D, and 400D for tube
removal.
5. Electric Panels- Most codes require 48 inches
(1219 mm) clearance in front of control boxes and
electrical panels. Check codes for your location.
6. 3.25-inch (83 mm) diameter lifting holes are provided.
See installation manual (available at www.DaikinApplied.
com) for lifting instructions.
7. All water connections are given in standard U.S. pipe
sizes. Standard connections are suitable for welding or
grooved couplings.
8. Unit shown has standard right-hand water connections.
Left-hand connections are available for either vessel.
For right hand evaporator the inlet and outlet nozzles are
reversed. ANSI-anged connections are available upon
request. When using ANSI-anged connections add 0.5
inch (13 mm) to each anged end.
9. Dimensions shown are for units (evaporator / condenser)
with standard design pressures. The waterside design
pressure is 150 psi (1034 kPa). Consult the factory for
unit dimensions with higher design pressures.
10. The unit vibration isolator pads are provided for eld
installation and when fully loaded are 0.25 inches
(6 mm) thick.
11. These values are for units with standard wall thickness
copper tubing only.
12. The shipping skid adds 4.00 inches (105 mm) to the
overall unit height.
13. If main power wiring is brought up through the oor, this
wiring must be outside the envelope of the unit.
14. The unit is shipped with an operating charge of
refrigerant.
15. Optional marine water box connections are available
upon request.
