Electrical Supply 

  • Independent power supplies from the distribution board using a RCBO C16 Breaker per pump in FP200 1.5mm 3 Core Cable (2 core + Earth)

  • Unswitched 13-amp Fused Spur, it must be adjacent to each pump


The Above Needs to be Installed by a Certified Electrician

We will need a copy of the Electricians Installation Certificate

Water Supply

  • Water supply with a 3/4” washing machine tap on each connection for each pump

  • Water supply needs to be 400mm from the floor and at least 80mm from wall so we can fit the filter and pump connectors.

Pump Sizes

  • H 365mm x D 240mm x W 181mm

  • Please allow adequate room for the connections at the rear of the pump at least 200mm in the back and 100mm in the front and sides.

Smartscan Hydra Head

  • These Heads are installed in the wall at 1400mm high from the floor.

  • The Head is designed to be affixed into a hole 90mm wide x 117mm high and 57mm deep.

  • If using a Back Box, the hole dimensions area as follows 95mm wide x 120mm high & 60mm deep

Cables & Hoses

  • Cables installed at first fix in the ceiling need to be visible when we return to commission so the engineer can connect to heat detectors

  • Once client has plastered and painted and ready for commissioning the system, the high-pressure hoses installed at first fix will need to be loose in the wall cavity so our engineers will be able to pull it out of the wall at least 2 inches to install the head

Heat Detectors

The Heat Detectors Installed are mains operated with Battery Back-Up - If the mains are turned off for a period of time the batteries will drain and start beeping and will need replacing at a cost to the client as this does not fall under the Warranty.
