Electrical Connection - Elwa HOTRUN-VE 38VE Operating And Installation Instructions

8. There is no need to install an overpressure relief valve.
9. The HOTRUN-VE range water heaters can be programmed to any temperature limit
required. At the time this manual was written only the 50°C limited models for sanitary
fixings for personal hygiene are exempted from the requirement of installing a TMV by
the plumbing code of Australia and as is required by AS3498 for testing and approval of
water heaters in Australia and New Zealand. New legislation is underway to cover this
exemption for all other temperatures.
10. Any set temperature between 35°C and 60°C, as temperature limit, can be programmed
into the water heater by ELWA. This setting can not to be changed by the end user after
installation. Ask for assistance from an ELWA technician if you need to change the
temperature limiter programming.
11. Each water heater is supplied for installation with exposed water and electrical
connections. However, water and electrical connections can also come in from the wall
through the back plate of the water heater (see template for positioning all connections
prior to fitting the unit to the wall). To do so, remove the inlet and outlet water
connections and use the supplied blanking grommets to close of the two holes. Allow for 2
elbows, 1/2" BSP male/female, to connect water to the nuts on the internal copper pipes.
12. The front cover of the model 38 to 96 can be rotated 180° to suit under-sink or over-sink
installation and enable the end user to read the temperatures in the display. The metal key-
hole bracket on the back plate can be rotated 180° for this purpose.
1. Local wiring rules and guidelines must be adhered to.
2. It is necessary to provide a dedicated circuit direct from the switchboard to each
HOTRUN.
3. The HOTRUN has to be connected to an isolator switch to be positioned next to the
water heater.
4. Check insulation resistance and proper earth continuity.
5. Fill the unit with water, and only then, switch the power on.
Attention: Avoid overheating. Fill the unit completely with water before turning on
the mains power supply. For that purpose:
Open the tap and wait until the water flows out from the spout without any air
bubbles.
Close the tap.
Switch-on the mains supply, Activate the HOTRUN on the control panel with on/off
push-button and the HOTRUN is ready to use.
