Installation.
(1) Refer to figure 5-11 and mount
the fluid pressure regulator against the
compartment wall using the mounting
clamp.
1.
Brazing operations should
be carried out using approved
eye protection equipment and
rods not containing cadmium.
2.
Certain brazing operations
may require mechanical venti-
lation.
3.
Local preventive medicine
personnel should be queried if
doubt exists as to rod compo-
sition or ventilation require-
ments.
(2) Solder the pressure regulator
to the refrigerant system tubing.
(3) Feed the sensing bulb through
the compartment wall and clamp in place.
(4) Refer to para 5-6 and leak test
the refrigeration system.
(5) Refer to figure 6-1 and purge
the refrigeration system.
(6) Refer to figure 4-4 and in-
stall the top covers.
1.
Caution should be exer-
cised with fluorocarbon re-
frigerant gas (freons) as they
can displace oxygen and there-
by cause suffocation.
2.
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 arryth-
mias, as a result of exposure
to fluorocarbon refrigerant
gases (freons).
Such indivi-
duals should be evaluated by
local medical authorities be-
fore working in environments
where potential freon exposure
may occur.
(7) Refer to figure 6-2 and
charge the refrigerant system.
