Drawing Notes

NOTES:

1. All dimensions are in inches and [millimeters] unless noted otherwise.

2. Final connections must allow for .500 inch +/- [12.7mm] manufacturing tolerances.

3. 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.

4. .375 inch [9 mm] suction nozzle relief valve must be piped per ANSI / ASHRAE 15.

5. Clearances:

Ends

108 inches (2743 mm) on WMC 145S/D and WMC 250D at one end

144 inches (3658 mm) on WMC 150D, WMC 290, and WMC 400D at one end

plus 36 inches (910 mm) is required at the opposite end. If tube pull and cleaning

clearance is at the connection end, do not block tube access with piping, pumps, etc.

Sides

36 inches (914 mm) is recommended on all other sides and top for service clearance

except unit front electric panels. See below..

Electric Panels

Most codes require 48 inches (1219 mm) clearance in front of the control boxes and

electrical panels.

6. 3.25-inch [83mm] diameter lifting holes are provided at the upper corners of each vessel. See

installation manual for lifting instructions.

7. All water connections are given in standard U.S. pipe sizes. Standard Victaulic® connections are also

suitable for welding.

8. The water connection shown is for the default configuration; your unit may be configured differently.

Orientation (left/right) is determined while facing the control panel. Consult the Item Summary sheet

for exact configuration. Unit shown has standard right-hand water connections. Left-hand connections

are available for either vessel. For left hand evaporator the inlet and outlet nozzles are reversed. ANSI-

flanged connections are available upon request. When using ANSI-flanged connections add .500 inch

[13 mm] to each flanged end.

9. Dimensions shown are for units (evaporator / condenser) with standard design pressures. The

refrigerant side design pressure is 200 PSI {1380 kPa} and 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 field installation. When fully loaded are 0.250 inches

[6 mm] thick.

11. These values are for units with standard wall thickness copper tubing only.

12. The shipping skid adds 6.0 inches [152 mm] to the overall unit height.

13. All-power wiring is brought into the top of the compressor power panel (Front End Box). Field control

wiring is brought into the Unit Control Box.

14. The unit is shipped with an operating charge of refrigerant.

15. Optional marine water box connections are available upon request.
