To determine which size your WPU is, compare your model number to the table below.  The first number(s) after "M-OD" refer to the nominal cooling capacity of your WPU in kW.  This translates to the nameplate tonnage of your unit.  For example, if your model # is "M.OD.13...", then your unit is a 3.5 Ton WPU (13 kW nominal cooling capacity).
