Be sure to route and secure accessory cables as shown to prevent cables from resting on hot surfaces. Accessory
cables may be damaged if they touch the dry pump, booster and spools during pump operation.
The route for the accessory cable around the GXS enclosure has been chosen carefully to ensure that the cable does
not rest on hot surfaces or pass over other cables carrying mains voltages. When fitting the accessory cable, carefully
follow the instructions given in the sections below. Ensure that cable ties are used as shown to keep the cable in the
correct position.
