RENEWAL PARTS IDENTIFICATION
WARNING: Type CVCHS Circulation Heaters are
equipped with INCOLOY
®
heating elements and cen-
tered in a CVPVC pipe body. It is the responsibility of
the user to know the chemical composition of the
corrosive solution and the character of the materials
entering the solution as well as the corrosive effect
of the solution upon the heating elements and cham-
ber. Chromalox cannot warrant any electric circula-
tion heater against failure by sheath corrosion if
such failure is the result of operating conditions
beyond our control.
WARNING:
1. Do not permit heater to operate when liquid has been drained
from chamber. Dry operation of the heater will cause failure and
possible fire hazard.
2. Terminal ends of heater must be protected from drippings, con-
densation, spray or direct spill-over of material. Their presence
at the terminals may damage heater electrical insulation. Liquid-
tight terminal enclosures are available to protect heater. Check
Factory.
1. WARNING: Hazard of Shock. Disconnect all power
before servicing heater.
2. If automatic reset cutout fails or will not reset, do not bypass.
3. Remove heating element assembly periodically to check heater
sheath for scaling, corrosion or excessive oxidation. Correct
operating conditions to minimize sheath deterioration.
4. Periodically check temperature control operation to insure accu-
rate and safe process operation.
5. Check all electrical connections periodically and retighten con-
nections which may have loosened in service. Replace wire and
wire terminals which shows signs of oxidation which would inter-
fere with establishment of reliable electrical connections.
