Connection to Electric Main
WATERMASTER I Series. Water Heater Models: WHE 3.5 XTR 1, WHE 4.5
XTR H1, WHE 5.5 XTR H1
1. The connection to the electric main is made with 1 m long electric
cable coming out from the device housing. If the cable length is in-
sufficient, it can be extended with the help of special sealed electric
contacts.
It is prohibited to use a plug and power receptacle when connecting
water heater to the main, except for model WHE 3.5 XTR H1.
2. Water heater shall be connected to AC electric main with 220 V volt-
age by a three-core electric copper cable with the minimum core
cross-section: for model WHE 3.5 XTR H1 3x1.5 mm2 and 16 A cir-
cuit breaker; for models WHE 4.5 XTR H1, WHE 5.5 XTR H1 3x2.5
mm2 and 25 A circuit breaker. In the event of wire cross-section in-
crease it should be noted that water heater and electric cable shall be
located on a thermally insulated or heated wall.
3. Water heater shall be stationary (constantly) connected to the power
supply (except for model WHE 3.5 XTR 1), 220 V AC, with compul-
sory connection to a ground electric loop. Make
sure that ground
loop resistance is < 4 Q .
ATTENTION !
It is prohibited to use a water heater without proper grounding.
WATERMASTER II Series. Water Heater Models WHE 5.0 XTN Z1, WHE 6.0
XTN Z1, WHE 6.5 XTN Z1, WHE 7.0 XTN Z1, WHE 8.0 XTN Z1
1. Power cable inlet is made at the smooth side of the device. It is pro-
hibited to use a plug and power receptacle when connecting water
heater to the main.
2. Water heater shall be connected to AC electric main with 220 V volt-
age by a three-core electric copper cable with the minimum core
cross-section: for model WHE 5.0 XTN Z1 3x2,5 mm2 and 25 A cir-
cuit breaker; for models WHE 6.0 XTN Z1, WHE 6.5 XTN Z1, WHE 7.0
XTN Z1 3x4 mm2 and 32 A circuit breaker; for model WHE 8.0 XTN
Z1 3x6 mm2 and 40 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 insu-
lated or heated wall.
4. For connection to power supply:
- Remove the front panel by unscrewing 2 screws at the device sides,
- Strip the power cord ends by not less than 7-10 mm,
- Pass the electric cable via electric cable inlet opening 10 (see Fig.4)
at the rear part of the device,
- 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 8 (see Fig.4)
according to its marking,
- Make sure that securing screws 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 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 1.
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 volt-
age by a four-core electric copper cable with the minimum core
cross-section: for model WHE 12.0 XTL C1 4x2.5 mm2 and 3x25 A
circuit breaker; for model WH 18.0 XTL C1 4x4 mm2 and 3x32 A
circuit breaker; for models WHE 21.0 XTL C1, WHE 24.0 XTL C1 4 6
mm2 and 40 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.
ATTENTION !
It is prohibited to use a water heater without proper grounding.
3. Water heater shall be stationary (constantly) connected to the power
supply (except for model WHE 3.5 XTR 1), 220 V AC, with compul-
sory connection to a ground electric loop. Make
sure that ground
loop resistance is < 4 Q .
