Wine Guardian publishes the D088 platform in two voltage columns, 208 V and 230 V, so every capacity and current figure below is tagged with the voltage it belongs to. The capacity ladder is published against condenser inlet temperature on the Wine Guardian ducted specifications sheet; the safe condenser inlet water temperature range for the water-cooled section is published separately as 45°F to 85°F.

Minimum circuit ampacity and the electric heat rating are printed on the Wine Guardian ducted specifications sheet as combined heat and no-heat values and are not reproduced here. Take both from that sheet and have a licensed electrician size the circuit, the disconnect and the overcurrent protection. The 125 lb weight and the 41.5 in x 22.5 in x 19 in dimensions above are the figures Wine Guardian publishes for the D088WC in the Additional Information table on its own product page; they describe the unit and its cabinet, not the crated shipping weight, so confirm the shipping weight with Wine Guardian before rigging is planned or freight is booked.
