HUDSON OWNER’S MANUAL 69
HUDSON WEATHER-MASTER
(Optional Equipment)
This unit (shown in Fig. 57) permits operation of the car in winter weather without the
necessity of opening the windows to eliminate window steaming. When the car is in
motion fresh air entering through the open cowl ventilator is filtered of dust and rain by
passing through a filtering pack in the cowl ventilator. The fresh, filtered air is then
heated as it passes through the heater core. Temperature control is provided by means
of a valve operated by a lever at the bottom of the heater housing. This regulates the
amount of hot water admitted to the heater. Outlets are also provided for defrosting.
The only source of intake air for the Hudson Weather-Master heater is the cowl
ventilator. Therefore the ventilator must be open when using the heater. Windows
should be closed tightly for best results.
The amount of heat output is best regulated by means of the water control valve oper-
ated by the handle mounted underneath the heater. Moving this handle toward the
right opens the water valve and gives maximum heat output. Moving it towards the
left reduces the water flow and permits the operator to adjust the heat output to suit the
weather and driving conditions. When the handle is moved fully to the left the water
flow is entirely shut off, permitting use of the cowl opening to obtain fresh, filtered air
in mild, summer or rainy weather.
