Installation.

(1) Refer to figure 5-5 and mount solenoid on compartment wall.

Blazing operations should be carried out using approved

eye protection equipment and rods not containing cadmium.

Certain brazing operations may require mechanical ventilation.

Local preventive maintenance personnel should be questioned

Caution should be exercised with fluorocarbon refrigerant

gas (freons) as they can displace oxygen and thereby

cause suffocation.

Personnel with a history or other evidence of cardiac

rhythm abnormalities should be made aware of the

potential for aggravation of existing cardiac rhythm

abnormalities or the induction of arrhythmias, as a

result of exposure to flourocarbon refrigerant gases

(freon). Such individuals should be evaluated by

local medical authorities before working in environments

where potential freon exposure may occur.
