-- IMPORTANT --
Always reference the full model number and serial number when calling the factory.
WARNING / CAUTION
1. Tank is to be completely filled with water and all air is to be vented before energizing.
2. Due to the rigors of transportation, all connections should be checked for tightness before
heater is placed in operation.
3. Safety relief valve must be installed in tapping provided.
4. The refractory material used in heating elements may absorb some moisture during
transit, periods of storage, or when subjected to a humid environment. This moisture
absorption results in a cold insulation resistance of less than ( ) megohms. If thisone 1
heater has been subjected to the above condition, each heating element must be checked
for insulation resistance before energizing. Contact the factory for a replacement element.
5. KEEP AWAY FROM LIVE ELECTRICAL CIRCUITS.
Do not perform any maintenance, make any adjustments, or replace any components
inside the control panel with the high voltage power supply turned on. Under certain
circumstances, dangerous potentials may exist even when the power supply is off. To
avoid casualties, always turn the power supply safety switch to off, turn the charge or
ground the circuit before performing any maintenance or adjustment procedure.
6. The unit is designed to operate at pressure not more than 150 psi.
7. Generalized instructions and procedures cannot anticipate all situations. For this reason,
only qualified installers should perform the installations. A qualified installer is a person
who has licensed training and a working knowledge of the applicable codes, tools,
equipment, and methods necessary for safe installation of an electric resistance water
heater. If questions regarding installation arise, check your local plumbing and electrical
inspectors for proper procedures and codes. If you cannot obtain the required
information, contact the company.
8. Water Quality Requirements – Recommended water hardness is 4 to 6 grains of
hardness per gallon (GPG). Water hardness above 6 GPG should be treated by a water
conditioner (water softener or in-line treatment). Water hardness below 4 GPG also
requires treatment to reduce potential corrosion. Excessive GPG will result in higher
operating and maintenance costs and will reduce product longevity. Chlorides must
not exceed 50 parts per million (ppm). Excessive chlorides will result in metallic
corrosion and will reduce product longevity. Water treatment has been shown to
reduce costs associated with de-liming the booster as well as reducing metallic
corrosion. Product failure caused by these conditions is not covered under warranty.
See warranty for complete details.
9. This water heater is not intended for space heating applications.
10. The water heater is factory set at 185°F for booster water heating applications. This
results in the possibility of a scalding water injury. A full thickness skin burn can
occur in less than one second of exposure to water at this temperature.

OPTIONAL FIELD CONVERSION FROM SINGLE TO THREE PHASE OR
THREE TO SINGLE PHASE (J6 and J16 models in 6, 7, and 9 kW at 208 and 240
volts and J411 models only)
1. Re-wire the unit to desired configuration as indicated below.
NOTE: The wire to be used for internal wiring must conform to SEW-2 or PTFE
(200°C) and must match the wire size currently in use. Contact the factory for
assistance, if required.
2. Contact the factory for correct labels. The factory will need the serial number for
proper identification.
Single-Phase 3-Phase
OPTIONAL 24-VOLT HEATER INTERLOCK ADAPTER
1. If desired, the heater can be wired to operate only when supplied with a 24-volt signal
through the heater interlock adapter. When no 24-volt signal is supplied through the
heater interlock adapter the heater is interlocked and will not energize. When
interlocked the display will show “ HLd”. The heater will resume normal operation
when a 24-volt signal is re-applied through the heater interlock adapter.
2. To utilize this feature, plug the 24-volt heater interlock adapter into terminal J1 of the
T1000 control board (note: if the XB1 expansion board is used, plug the adapter into
terminal JX3 of the XB1) and verify that the configuration is set to Hon”, see the
controller operation section for further detail. The signal can be either AC or DC.
However, if a DC signal is utilized and the interlock feature does not operate, switch
the two 24-volt supply wires at the heater interlock adapter.
FINAL CHECKS
1. Check all connections for tightness.
2. Ensure that all the above steps are completed.
3. Remove the protective outer plastic covering from the sheet metal shell.
4. After the water is heated for the first time, monitor the water temperature as described
in Section III, Annual Inspection.
