d) Careful preparation can expedite the commissioning of your heater. Most delays can be
avoided by following the instructions in this manual. Failure to complete required
procedures properly can result in the need for further service time, at extra cost to the
customer.
e) Service people will not commence start-up if there are obvious system deficiencies.
However, start-up service in no way constitutes a system design check or approval of the
installation.
f) In addition to commissioning the heater, the service person will also familiarize heater
room personnel with the operation of all Fulton equipment. Personnel must be qualified to
understand the basic operation and function of controls.
8. Cold Circulation
a) Turn on the main power switches.
b) Check for proper fluid level in the expansion section of tank.
c) A centrifugal pump cannot be operated with the discharge valve closed without heating
up dangerously.
d) The pump should be started with the suction valve full open and the discharge valve
open a slight amount.
e) Check pump rotation. Operating the pump in reverse rotation may cause extensive
damage.
f) Turn the three position switch located on the front of the panel box door to “Pump”.
g) Jog the green pump motor starting button and observe the direction of rotation. Rotation
should be in the direction of the arrow shown on pump casing.
h) If the rotation direction is incorrect, turn the three position switch back to “Off”
immediately. Change the wiring connections and recheck.
i) Check for proper alignment. Realign, at temperature.
j) With the control switch set to “Pump” push and hold the pump start button, check all
manual resets on pressuretrols. The circulating pump will run, but the burner will not fire.
k) If the pump stops when the button is released, check for proper flow in the system, and
review settings of high and low fluid pressure switches and differential pressure switch.
Check liquid level switch.
l) Check that all pressure gauge readings remain stable. Pressure exceeding 100 PSIG or
identical readings at inlet and outlet gauges indicate a closed valve.
m) If an extremely high vacuum (i.e.15” Hg or more) is indicated on the compound gauge,
the valve between the circulating pump and the combination tank may have been left
closed. In this case, little or no pressure will be indicated by other gauges.
