START-UP

5.1

PRE-START INSPECTION

This Trebor DI Water Heater has been thoroughly tested and inspected
for proper performance and operation prior to leaving the factory.
Additional pre-start inspection can identify any damage or condition
change that may have occurred during shipment of the heater and
reduce nuisance problems during start-up.
5.1.a Verify Shipping Condition
Refer to Section 3.1, Unpacking.
5.1.b Hazardous Power Terminals
Refer to PM Schedule, Section 4.3.b. Tighten hazardous power
connections at the main circuit breaker, distribution circuit breakers,
distribution contactors and SSRs. Slightly loose connections at these
hazardous power terminals can cause arcing. This arcing can introduce
higher than normal operating temperatures, resulting in damage of
electrical components. Tighten terminal in a clockwise direction only.
Do not loosen terminals before tightening as this may affect the contact
area.
5.1.c Electrical Inspection
Refer to system schematic. Visually inspect all electrical components for
anything that seems unusual, such as damaged wire insulation,
disconnected wires, etc.
5.1.d Plumbing Leak Check
Refer to PM Schedule, Section 4.3.b. Inspect heater for leaks during
start-up. Open the front door and visually watch the leak tray as the
system is initially filled with water. Visually inspect heater module
fittings and heater system plumbing for leaks.
If leaks are found at the flare fittings, hand tighten fittings while they
are at ambient temperature. Do not use a wrench to tighten flare
fittings, as excessive tightening can cause damage to the fittings.
If any problems are encountered during start-up of this heater, contact
Trebor for technical support.
