1.6 Controller
The RAC1509 and RAC15125 heaters are supplied
with a remote controller. The remote control unit
houses 3 single pole and 1 change over 10A rocker
switches. The controller is wired to the base unit via
0.75mm² 5 core PVC flexible cable.
1.7 Clearance Distances

100mm is allowed around the case and 55mm
above. The clearance allows for cable entry and
prevents combustible surfaces overheating.

The maximum mounting height is 3m.
1. General Information
1.1 Introduction

prevent heat loss. Will fit a recess as shallow as
195mm.
