Hose Size and Lengths

The

system comes with a hose set consisting of a 1 in. ID x 25 ft (25 mm x 7.6 m) fluid hose and a 3/8 in. ID air hose. The 1 in. hose set includes an adapter hose between the gun and main hose. See parts, page 22.

Use the shortest length possible when spraying. In creasing hose length decreases sprayer performance. Do not use more than 75 ft (23 m) of fluid hose.

CAUTION

This

system is designed for use with only certain

types of material. Any other use could seriously

damage the unit.



Do not use any solvent-based materials. Use only water-based materials.



Use only simulated acoustic and gypsum-based wall texture materials in this system.



Do not spray cementious materials, which will damage the pump.

Proper material mixture is essential. The pump won’t operate if the material is too thick.

Mix material in a separate container and pour into the hopper for best results.

Slowly add one bag of texture material to clean water as instructed on the bag instructions. Agitate to a smooth, lump-free consistency. Thin the material as needed before pouring it into the hopper. For the best results, do not use partial bags of material.
