CAUTION
Do not use this equipment if any part
has been under water (or subjected to
heavy rains/water if the equipment
does not have NEMA 4 wiring, controls
and instrumentation). Immediately
call a qualifi ed service technician to
inspect the equipment and to replace
any part of the control system and/or
gas control(s) which have been under
water.
A temperature exceeding 120°F** in
the boiler room may cause premature
failure of electrical components.
Provisions should be made to maintain
an ambient temperature of 120°F**
or less (the panel box interior should
not exceed 125°F**). **Pumps, PLC or
ModSync panels may require lower
ambient temperatures or additional
cooling.
Initial Start-Up
These instructions are for use when the unit is being started up for the fi rst
time, or after prolonged shutdown. They are to be used in conjunction with the
specifi c procedure information in manual section Routine Operation.
Cold Circulation
1. Turn on the main power switches.
2. Check for proper fl uid level in the expansion section of tank. See Figures
and 11 and 12.
3. A centrifugal pump cannot be operated with the discharge valve closed
without heating up dangerously.
4. The pump should be started with the suction valve full open and the
discharge valve open a slight amount.
5. Check pump rotation. Operating the pump in reverse rotation may cause
extensive damage.
6. Turn the three position switch located on the front of the panel box door
to “Pump”.
7. 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. If the rotation direction is incorrect, turn the three position switch
back to “Off ” immediately. Change the wiring connections and recheck.
8. Check for proper alignment. Realign, at temperature.
9. 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 fi re.
10. If the pump stops when the button is released, check for proper fl ow in the
system, and review settings of high and low fl uid pressure switches and
diff erential pressure switch. Check liquid level switch.
11. Check that all pressure gauge readings remain stable. Refer to Figure
15. Pressure exceeding 100 PSIG or identical readings at inlet and outlet
gauges indicate a closed valve.
12. 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.
13. Check all piping, connections and users for leaks. Repair any leaks
immediately.
