CAUTION
Use caution when using any cleaning
solutions. Refer to local regulations for
proper cleaning solution disposal.
Do not allow oil leaks, dust, or dirt to
accumulate around the boiler.
To protect unit components and
prolong equipment life, it is essential
that regular inspections are carried out.
The most common causes of failure are
excessive scale build-up and corrosion.

Handhole Gasket Installation
1. Remove old gasket and thoroughly clean the surface on boiler and on
plate.
2. Place neoprene gasket on handhole plate. Be sure the gasket is pushed
down tight on the plate. Do not use any grease, lubricant or adhesive.
3. After plate is in boiler and gasket is in place, set yoke and tighten nut only
enough to provide a snug fi t. See Figure 4. Make it hand tight then snug
with wrench about ¼ turn. Do not compress excessively as neoprene
gaskets should never be compressed as much as the old asbestos type.
4. If gasket leaks while pressure is being built up, tighten only enough to stop
leakage. Never tighten more than necessary to prevent leakage. Excessive
tightening may shorten life of gasket.

Scale Formation
The dangers of scale to the life of the element cannot be over stressed. Scale
possesses excellent insulating qualities and its formation on the element
prevents the heat generated by the element from being transferred to the water,
causing the element to overheat and burn out. Loose powdery formations can
be removed with a wire brush. Hard scale may be removed using a mild chemical
cleaning agent followed by a neutralizing agent.
Elements, if stored correctly, have an indefi nite shelf life. However, problems will
arise if they are stored in damp or humid conditions. Moisture can be absorbed
by the insulation as the elements are fi tted with a breathing seal.
