3. Water heater shall be stationary (constantly) connected to the power
supply (except for model WHE 3.5 XTR 1), 380 V AC, with
compulsory connection to a ground electric loop. Make sure that
ATTENTION
!
It is prohibited to use a water heater without proper grounding.
4. For connection to power supply:
- Remove the front panel by unscrewing 2 screws at the top part of the
device and 1 screw at the bottom part,
- Strip the power cord ends by not less than 7-10 mm,
- Pass the electric cable via electric cable inlet opening 13 (see Fig.6) at
the rear panel of the device housing,
- Remove the clamping plate holding the electric cable, do not lose
the positioning screws, make sure that the cable is not touching
sharp edges and hot surfaces,
- Connect the electric cable wires with junction block 11 (see Fig.6)
according to its marking,
- Make sure that securing screws of the junction block are tightened
correctly. Untight connection may result in heating of wires,
- Install the electric cable plate into the main position with the help of
positioning screws, make sure that the cable cannot be pulled out,
- Check the tightness of connection of all internal electric contacts,
including detachable contact blocks and bolted contact connection
at heating elements. If there are any loose items, fix and tighten
them,
- Install the front panel and tighten 2 screws at the top part and 1
screw at the bottom part of the device.
7. WATER HEATER OPERATION
WATERMASTER I Series. Water Heater Models: WHE 3.5 XTR H1, WHE 4.5
XTR H1, WHE 5.5 XTR H1
1. During the first water heater start-up or after long-term non-use, fill
the device with water by opening the cut-off tap at cold water
supply line, and make sure that there is a steady cold water flow at
water outlet at the consumption point, after that switch on the
device power supply.
2. Incoming water is heated up inside the heating flask when it is
flowing through the heating element. Water temperature in the
water supply main may vary depending on a season from +3° to
+20° , so, in winter water flow shall be less than in summer to
assure the optimum water temperature.
3. Water flow is controlled by the tap at water inlet to water heater. It
is prohibited to install the cut-off tap and/or shut off water supply
at the outlet from water heater.
4. When there is water flow, and water pressure is not less than 0.15
MPa, heating is switched on automatically, and indicating lamp 2
located at the front panel lights up (see Fig.1).
5. After heating is switched on, you need to wait for 10-20 seconds to
let temperature of heated water stabilize.
6. The tap at the inlet nozzle (cold water inlet) can be used to regulate
hot water temperature. By reducing water flow you increase water
temperature at the outlet and, correspondingly, vice versa.
7. To switch off the water heater, simply close water flow at the inlet to
the device; pressure sensor automatically opens the circuit of
power supply to heating element, and indicating lamp 2 located at
the front panel goes down (see Fig.1). For the subsequent switching
on of heating it is enough to reopen the tap supplying water to
water heater.
ATTENTION
!
Water heater of WHE 3.5 XTR H1 Series, 3.5 kW, is designed for using
during summer period with water temperature at inlet to water
heater not less than +16 -+18°
ATTENTION
!
Do not switch on the water heater if there are grounds to suspect
that water inside it has frozen.
