Connection to the water main
WATERMASTER I Series. Water Heater Models: WHE 3.5 XTR Н1, 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 insufficient, 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 voltage by
a three-core electric copper cable with the minimum core cross-section: for
model WHE 3.5 XTR H1 – 3x1.5 mm
2
and 16 A circuit breaker; for models
WHE 4.5 XTR H1, WHE 5.5 XTR H1 – 3x2.5 mm 2 and 25 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.
3. Water heater shall be stationary (constantly) connected to the power
supply (except for model WHE 3.5 XTR Н1), 220V AC, with compulsory
connection to a ground electric loop. Make sure that ground loop resistance
is < Oм.
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 prohibited
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 voltage 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 circuit breaker; for models
WHE 6.5 XTN Z1 – 3x4 mm 2 and 32 A circuit breaker; for model WHE 8.0
XTN Z1 – 3x6 mm 2 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.
3. Water heater shall be stationary (constantly) connected to the power
supply (except for model WHE 3.5 XTR Н1), 220 V AC, with compulsory
connection to a ground electric loop. Make sure that ground loop resistance
is < Oм.
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,
