Make sure that the water heater is operable passing water flow through it.
Check tightness of all connections and, if necessary, tighten nuts and
mounting screws including screws in flanges of the heating vessel.
NOTE:
Before installation of the water heater, flush water pipes with flowing
water.
Connection to electric mains
The water heater shall be connected to the 220VAC electric mains with a
three-core electric cable (not more than 15 m long to the maximum).
Minimum wire section of 3x1.5 mm (copper) with a 16A circuit breaker -
for water heaters of WHEL-3... series
Minimum wire section of 3x2.5 mm (copper) with a 25A circuit breaker -
for water heaters of WHEL-6... series
Minimum wire section of 3x4 mm (copper) with a 30A circuit breaker - for
water heaters of WHEL-7... series
Connection to electric circuit:
- It is necessary to increase wire section, if the water heater and electric ca-
ble itself are located on a thermally insulated or heating wall.
- The water heater shall be connected to the electric mains stationly ( exept
WHEL-3... ) .
- Install an external circuit breaker for protection of the electric circuit
(16/25/30A depending on series of the water heater).
- Lead the electric cable into the water heater.
- Fix bare ends of the electric cable in a connection box hardly tightening
them with screws and in strict correspondence with the box marking (re-
fer to Fig.3)
- Check connection tightness of all internal electric contacts including re-
movable contact groups and bolt contact connections on heating ele-
ments. If there are loose connections, they shall be fixed and tightened.
- Connect the electric cable with the fixed method (exept WHEL-3...) to the
220VAC power supply source using a circuit breaker (16/25/30A depend-
ing on series of the water heater) with obligatory electric grounding.
- Install the enclosure of the water heater and tighten three mounting
screws.
- Switch on the 220VAC power supply and check operability of the water
heater with the practical method in all operation modes.
ATTENTION!
The water heater requires obligatory connection of electric ground-
ing.
It is necessary to increase wire section, if the water heater and elec-
tric cable itself are located on a thermally insulated or heating wall.
The water heater shall be connected to the electric mains perma-
nently (with a fixed method).
