Page 17: Installation
Installation Always read the safety instructions in Section 1 of the manual before installing UniQ eHW Heat Batteries. Installation Process Preparation: • Assess the location of installation considering spatial requirements, clearances, cable runs and tube runs. • Unpack and discard or recycle packaging according to local disposal or recycling rules. - Page 18 Deburr the tube end, both internally and externally to create a 1mm chamfer on the outside of the tube. Check the tube ends are free from damage and clean, wiping away any swarf to avoid damaging the ‘O’ ring on tube insertion. Tube end must also be free from stickers, tape and adhesive residues.
- Page 19 Final Fit After Commissioning: Commissioning instructions are provided in Section 4 of this manual. Follow the instructions below after commissioning. • Cut the 32mm thick insulation layer to suit the tube and cable entries. This layer has several perforations for guidance. This can be done with a sharp knife or scissors.

Page 23: Hydraulic Requirements
Hydraulic Requirements Sunamp Ltd Heat Batteries are NOT suitable for tank-fed hot water systems. • All connection tube work inside the Heat Battery casing must be Ø22mm copper tube. This is to allow the earth connection between the case, inlet, and outlet tube fittings. -
Page 24: Electrical And Wiring Requirements
Electrical and Wiring Requirements All range models within this manual are fitted with an internal controller situated at the top of the Heat Battery. Two wiring options are available: 1. No time-switch: 24-hour electricity grid supply only. 2. Time-switch: Standard electricity grid supply only. Zero Volt Time switch with options for tariffs such as E7 and E10. - Page 25 • The mains power cable to the Sunamp Controller should be a minimum of 2.5mm², 3 core HO5 VV-F sheathed cable, to BS 6500. This cable must be prepared according to Figure 10 (below), where the Green/ Yellow (Protective Earth) wire is 15mm longer than the Brown (Live) and Blue (Neutral) wires.
