Glacia Second Stage Service & Repair Manual

DISASSEMBLY PROCEDURES

NOTE: Before performing any disassembly, refer to Table 3, which references all mandatory replace-
ment parts. These parts must be replaced with new, and must not be reused under any circum-
stances - regardless of the age of the regulator or how much use it has received since it was last
serviced.
CAUTION: To prevent damage to critical sealing surfaces, use only a plastic or brass o-ring removal
tool (P/N 944022) when removing o-rings. Once an o-ring sealing surface has been damaged, the
part must be replaced with new in order to prevent the possibility of leakage. DO NOT use a dental
pick, or any other type of steel instrument.
1. While holding the inlet fitting (31) of the second stage secure with a 19mm (³⁄₄") open end wrench,
apply an ¹¹⁄₁₆" open-end wrench to the female fitting of the LP hose (35). See Fig. 1. Turn the fitting
counterclockwise to loosen and remove the hose from the second stage. Remove the o-rings (34 & 36)
from the hose and discard. Set the hose aside.
2. Remove the lip shield (25) by gently pulling it over the mouthpiece (24). Carefully snip the plastic
mouthpiece clamp (23) and remove the mouthpiece from the box bottom (29). Inspect the mouthpiece to
ensure it is free of any tears or cuts that may cause leakage of water into the second stage or other dis-
comfort. Discard the mouthpiece or set it aside to be reused, depending on its condition.
3. Remove the exhaust tee (6) by holding the second-stage firmly in one hand and, with the other hand,
pulling the exhaust tee from one corner (see Fig. 2). Remove the exhaust valve (22) by grasping it with
your fingers and pulling straight outward.

CAUTION: Do not use a
tool to remove the ex-
haust tee. Doing so may
cause serious damage to
the seating flange, requir-
ing replacement of the
box bottom.
