Warning
When dissolved, the solution is a severe irritant and must be treated in the same
manner as all strong acids. If any of the solution comes into contact with eyes or
skin, flush immediately with a large volume of water. If the eyes are affected, seek
immediate medical attention.
5. Cleaning the Water Probes
a) Clean the probes in the water column. Make sure there is no pressure on the SteamPac
during the removal of the probes. Remove one probe (using 7/8” socket) clean with a
very fine emory cloth and replace it before removing another probe to assure no probe
mix-ups that would change the control functions.
6. Feed Pump
a) The better the pump is maintained, the longer its working life will be.
b) In many cases it is not possible to install the pumps in places where they are protected
against frost (especially when used in conjunction with steam generators.)
c) Please follow these special instructions to prevent damage.
d) As soon as the boiler has been shut down, the pumps must be carefully drained.
e) Before the pump is returned to service, the pump should be primed with hot water and
turned several times by hand. Only then should the equipment be started up.
7. Electrical Controls
a) Monthly – Check that connection screws have not become loose. Clean electrical
contacts on relays etc. inside the panel with a small brush.
b) Check operation of the controlling pressure switches.
c) When the unit is in operation, reduce the setting of the pressure switches to a value well
below that of which they normally operate.
d) The steam pressure control should shut the fluid control valve.
e) The excess steam pressure switch should shut the fluid control valve.
8. Miscellaneous
a) Check tightness of all joints or flanges on the water, steam, and thermal fluid piping.
Tighten or replace any leaking valve packing. Note: Shut off and cool the system prior to
replacing valve packing.
