8. 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°С to +20°С, so, in winter water
flow shall be less than in summer to assure the optimum water temperature.
IMPORTANT!
It is prohibited to use a water heater without proper
grounding.
IMPORTANT!
Neutral conductor is not used in the electric circuit of
this water heater.
- 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 block and bolted connection at heating elements.
If there are any loose items, fix and tighten them,
- Install the front panel and tighten 2 screws at the device sides.
WATERMASTER III Series. Water Heater Models: WHE 12.0 XTL C1, WHE
18.0 XTL C1, WHE 21.0 XTL C1, WHE 24.0 XTL С1.
1. Electric cable inlet is made at the rear side of the device.
2. Water heater shall be connected to AC electric main with 380 V voltage by
a four-core electric copper cable with the minimum core cross-section: for
model WHE 12.0 XTL C1 – 4x2.5 mm
2
and 3x25 A circuit breaker; for model
WHЕ 18.0 XTL C1 – 4x4 mm
2
and 3x32 A circuit breaker; for models WHE
21.0 XTL C1, WHE 24.0 XTL C1 – 4х6 mm
2
and Зх40 A circuit breaker in
the event of wire cross-section increase it should be noted that water heater
and electric cable shall be located on a thermally insulated or heated wall.
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.
3. Water heater shall be stationary (constantly) connected to the power
supply (except for model WHE 3.5 XTR Н1), 380 V AC, with compulsory
connection to a ground electric loop. Make sure that ground loop resistance
is < 4Q.
