D.6 BASIN HEATER
Maintenance
1. Check for leakage around screw plug.
2. Periodically inspect heater sheath for evidence of scale build up, sludge, corrosion, or “dry re.”
Clean sheath when necessary to remove scale or sludge.
3. Periodically check line connections for tightness and evidence of moisture, oil, or dirt. If these conditions
are evident take the necessary steps to correct the problem. Water, oil , and dirt can enter the heater
through its terminal end causing premature failure. If this is severe the unit should be taken out of
service and tested. We recommend that it be returned to the factory for cleaning and testing.
4. If there is evidence of corrosion or a “dry re” the unit should be taken out of service and replaced
before a failure occurs.
5. Assemble screw plug in mating coupling in tower basin using appropriate sealing tape or compound
to prevent leakage at joint.
6. If heater is to be installed in horizontal position (immersed length parallel to the tank bottom) make
sure heater is adequately supported over its immersed length.
7. Heater should be positioned so that the heater is completely immersed, with uid, at all times under
the minimum liquid level or ow conditions. Heater should be covered with at least 2” of uid, and
must be located above any sludge or deposits that may collect in the bottom of tank. If heater is
subject to a “dry re” heaters failure will occur resulting in those hazards.
8. Make sure power supply leads have been turned “off” or are disconnected before attempting to
make any electrical hook-up.
9. Remove housing cover. Connect housing using appropriate conduit. Connect lead wires to respective
terminals. Make sure connections are tight, in accordance with proper procedures as in any electrical
hookup of this type. When connecting supply leads make sure the lead is sandwiched between the
two at washers provided on the unit. It is important not to put more than 10 inch pounds of torque on
the terminal pin of the heater. Greater torque will cause the terminal stud to twist off in the heater.
Proper lead wire selection is mandatory. Connect ground wire to appropriate ground lug on unit.
10. Replace housing cover. If a gasket is used make sure gasket is properly seated before assembling
cover.
11. Fill tank with uid or turn on uid ow. Check for leaks. In closed tanks make sure that all trapped
air is removed from the tank. Bleed the air out of the liquid piping system and heater housing prior
to operation.
12. After tank is full or ow is established turn heater on.
These instructions do not purport to cover all details or variations in equipment nor to
provide for every possible contingency to be met in connection with installation, operation,
or maintenance. If further information is needed for a particular application problem contact
the factory.
CAUTION
The inmension heater should be covered with at least 2” of uid, while heater is
energized to prevent any failure by overheating.
