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 High Power Terminals
Refer to PM Schedule, Section 7.3. Tighten high power connections at
the main circuit breaker, main contactor, SSR’s, distribution blocks, and
fuseblocks. Slightly loose connections at these high 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 7.3. Inspect heater for leaks during
start-up. Remove access panels to the heater modules and open the
heater module top caps during start-up. 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, excessive tightening can cause damage to the fittings.
If leaks are found at the heater element fittings, cinch the fittings up
using an end wrench. If the leak does not cease, remove element
fittings and inspect the ferrule inside for damage.
If any problems are encountered during start-up of this heater, contact
Trebor International for technical support.
