w water from the safety valves goes via nonpressurised collecting pipes to a drain so that hot water splashes cannot cause injury. These non-pressurised collecting pipes shall not be used for anything else. A discharge pipe from the tundish connected to the expansion relief valve (safety valve) shall also be connected to a drain in the same way. Please note that the connection of the T&P-valve should not be used for any other purpose. Valves may not be positioned between the expansion valve and the vessel.

5 Electrical installation NOTE

Electrical installation and service must be carried out under the supervision of a qualified electrician. Electrical installation and wiring must be carried out in accordance with the stipulations in force.

Sensors (See page 10) The Titanium Megacoil can accommodate up to two hot water sensors, one for SMO Controller display and one to control start and stop of heat pump. The display sensor is positioned in the submerged tube for the display sensor (UA1) and the control sensor in the submerged tube for control sensor (UA2). In cases where it is only possible to connect one sensor, use the submerged tube for control sensor (UA2). Titanium Megacoil/Megacoil-Solar can also be supplemented with a solar sensor. This is placed in the submerged tube for solar sensor (UA3). Use the sensors provided with the heat pump/control module. When no heat sensors have been provided, these must be ordered from the manufacturer of the heatpump/ control module.

6 Commissioning and adjusting NOTE

Filling and venting the charge coil

At the time of commissioning, complete all relevant sections of the Benchmark Checklist located at the back of this document.

Filling and venting

Completion of the Benchmark Checklist is a condition of warranty. For full terms and conditions of warranty, please see our website www.nibe.co.uk.

Filling and venting

1.

Open the g valve (external, not included with the product). Fill the coil in the hot water heater and the rest of the climate system with water.

2.

Vent the coil and the rest of the climate system via the relevant venting valves.

3.

Keep topping up and venting until all air has been removed and the pressure is correct.

Filling the hot water heater 1. 2.

Open a hot water tap in the house. (XL4)

3.

When the water that comes out of the hot water tap is no longer mixed with air, the water heater is full. Flush the system for several minutes and the tap can be closed.

Fill the hot water heater through the cold water connection (XL3).

After servicing, complete the relevant Service Interval Record section of the Benchmark Checklist located at the back of this document.

If this pressurised water heater develops a fault, e.g. a flow of hot water from the overflow pipe, turn the heat pump offand contact your installer.

Completion of the Service Interval Record is a condition of warranty. For full terms and conditions of warranty, please see our website www.nibe.co.uk.

Cleaning Inspect and clean the water heater by using a suitable instrument such as an endoscope. The hot water connection (XL4) must be removed to facilitate access.

NOTE

Any servicing must be carried out by a competent person.

Emptying The water heater is emptied through the drain cock (with hose connection) in the cold water connection (XL3).

Maintenance

Drain the charge coil through the siphon (with hose) on the docking connection, return to heat pump (XL9).

General inspection

Drain the solar coil through the siphon (with hose) on the connection, return to solar heating system (XL14).

Check the following:

1. Condition of casing. 2. Electrical connections. 3. Pipe connections. Correct any fault before continuing.

Hot water heater Check the following: Expansion relief valve. T&P valve. Discharge pipe. Expansion vessel.

Service actions Safety valves The function of the safety valves must be checked regularly. Perform checks as follows:

Mega Coil 160, 200 & 300

1. Open the valve by turning the knob anti-clockwise carefully.

2. Check that water flows through the valve. 3. Close the valve by releasing it. Ifi t does not close automatically when released, turn it anti-clockwise slightly.
