Start-Up / Operation
2.0.1
Start-up check list
a)
Water supply and Drain Connections
:
these should be connected as indicated
under Plumbing and in accordance with the
relevant local regulations. An isolation valve
should be adjacent to the unit. The
connecting metal plumbing must be
grounded close to the unit.
b)
Steam Line:
This must be connected
according to the installation instructions with
adequate slope and support.
c)
Power supply:
Wiring to the Vapanet unit
Should be by a qualified electrician and
comply with the relevant regulations using
appropriately sized cable and cable glands,
with disconnect and fuses to suit the
maximum fuse rating of the unit at the supply
Voltage. The disconnect/fuses should be
adjacent to the unit or within easy reach and
readily accessible.
d)
Control Connections:
Ensure the control
signal and security circuit are
correctly connected according to the relevant
instructions/diagrams.
e)
VAPANET 24v / 9V Control Circuit
Transformer:
The
standard
24V
transformer used in the units has primary
winging for 200V, 220/240V, 380V, 415V, &
440v 50/60Hz connection derived from the
local electrical supply.
Note: 60Hz connection must be specified
with order as 230V 60Hz pump is required.
f)
The maximum output & kW rating of the unit
is determined by the number and electrical
rating of the heater elements fitted in the
cylinder. It is not possible to “de-rate” the
unit.
g)
Unit Configuration Plug (U.C.P.). Provides
the Vapanet control PCB with information
regarding the “system hardware” i.e. the size
of the cylinder and whether the unit is an
“On/Off” (“LR”) or “Proportional” (“LRP”)
model. It is fitted directly onto the control
P.C.B. If a display is fitted only one resistor
is fitted to the UCP, but if no display is
present additional resistors need to be
present to provide sufficient information for
the unit to operate. If insufficient information
is available the unit will remain in the
“not_config” state until the information is
supplied. This additional information is
provided via the keypad – when the display
is fitted.
A brass earth stud is fitted behind the transformer
cover to enable this to be easily completed.
See Page 7 / Appendix 1.
See Page 10/11.
See Page 13.
This is fitted below the stainless steel drain tray. To
gain access, open the front access door, remove the
two M4 screws and remove the transformer cover by
sliding it forward.
Above:
UCP1 fitted to Control PCB as if a display is
fitted to the unit.
Right:
UCP’s fitted to Configuration PCB Part number 1150634,
as if a display is not fitted to the unit.
Thermistor input from control terminals 1 & 2 (Not shown) are
connected to Configuration PCB CR1.
The Jumper plugs (
J1
) should be used to select the site demand
signal type (from the following options: 0-5V; 0-10V; 2-10V; 1-18V;
0-20V; 4-20mA
[jumper J1 on main PCB should also be made – see
page 13]
Pot.; Full O/P; Network or Slave.) and (
J2
) the site water
quality (from the following options: De-min; De-ion; softened, Pot.
Low; Pot. Medium; Pot. High).
