CBWMV Unit Parts Description

Blower

The CBWMV is equipped with a variable speed motor that provides separate cooling and heating CFM selections and low continuous fan speeds.

Hot Water Coil

The copper tube coil is equipped with aluminum fins which provide excellent heat transfer. Manual air bleed ports are located in the copper tubing to release trapped air in the water circuit in all unit configurations.

Blower Control

The control provides a fixed blower delay of 45 seconds ON / 30 seconds OFF on a W call.

Thermostat and accessory connections are made to the terminal strips in the control box.

CBWMV Unit Optional Accessories

Accessory Circulators (53J76, 99K69)

An accessory circulator should be used in long line ap- plications. Two circulators are available with either 9 gal- lons per minute (99K69) or 14 gpm (53J76) flow rate. Both units have 7/8" soldering joints (inlet and outlet) . See pip- ing section for more information.

Downflow Base (68M03)

A downflow base kit is available for downflow applications without add−on cooling coils. The base provides clearance for routing the CBWMV unit’s inlet and outlet water lines.

NOTE − Downflow applications with an add−on cooling coil require field−fabricated transitions to provide adequate clearance for servicing/removing the cooling coil without cutting the water lines.
