Lochinvar NSF SSB-i & s--01 - Manual

Electric booster water heaters are available for operation on standard
power systems. Check the nameplate for the proper power supply.
All internal electrical connections have been made at the factory. See
Circuit Breaker and Fuse Sizing Chart for supply wire size, fuse,
breaker and conduit recommendations.
AL CONNECTIONS
1. Locate the heater terminal or fuse block(s) in the control box.
The control box is under the front hinged jacket cover.
2. Bring power leads from a properly sized fused disconnect
switch or circuit breaker through knock-out provided in base
and connect to the terminal or fuse block(s). USE COPPER
WIRE ONLY.
3. A grounding lug is provided near the supply terminals. An
equipment grounding conductor must be properly connected
to it.
4. Replace and secure cover(s).
For the most effective operation install the booster heater as close as
possible to the dishwasher.
TEMPERATURE AND PRESSURE RELIEF VALVE
For protection against excessive pressures and temperatures in the
booster heater, install temperature and pressure protective equipment
required by local codes. The manufacturer supplies valves constructed
with brass working parts and heat resistant silicone seat discs for all
booster heater models.
Temperature/pressure protective equipment should not be less than a
combination temperature/pressure relief valve certified by a nationally
recognized testing laboratory that maintains periodic inspection of the
production of this equipment and meets the requirements for Relief
Valves and Automatic Shutoff Devices for Hot Water Supply Systems,
ANSI Z21.22-latest edition. The temperature/pressure relief valve
must be marked with a minimum set pressure not to exceed the marked
hydrostatic test pressure of the booster heater.
Valves supplied by manufacturer are designed for
high temperature commercial operation. Do not
substitute OEM valves with valves designed for
domestic water heaters.
WARNING !!
To assure proper operation and avoid a possible
unsafe condition, the booster heater must be
installed in a horizontal position with the base
parallel to the floor and the inlet connection at the
lowest point.
WARNING !!
Employ recirculation if distance between booster
and dishwasher exceeds NSF specifications.
NOTE:
PLUMBING INSTALLATION
INSTRUCTIONS
Do not turn on power to booster heater until the
tank has been filled with water and all air has been
vented through the dishwater rinse nozzle. The
heating elements will burn out in seconds if operated
when they are not immersed in water, unless the
heater is equipped with a low-water cutoff (LWCO).
CAUTION !!
ELECTRICAL CONNECTIONS
The main power circuit must be disconnected prior
to performing any maintenance on the booster
heater to avoid possible personal injury or damage
to the heater.
WARNING !!
For proper electrical installation conforming to local
electrical codes, consult a licensed electrical
contractor.
