    6. INSTALLATION 6.1. INTRODUCTION Horizontal models size 04, 08, 12, 16, 21, 27 and 33 These models are designed to be installed hanging from the ceiling or located behind a false ceiling. When installing the unit, is mandatory to distribute the unit weigh between all the supports existing in the units: •...
  • Page 7 Vertical models The models size 4 to 33 are supplied with support feet, while the models size 45 to 100 are supplied with a perimetral bed. This bed must be in contact with the ground or with a fl at surface. It is es- sential that the weight of the equipment is distributed between all points of support to prevent unit deformation.

    d) Vertical versions of CADB/T HE 45, 60 and 100 In these versions, the drainpipe and the siphon are supplied mounted in the unit. 6.1.1. Outdoor installation Whenever possible, it is advisable to be mounted indoors. When it is installed outdoors,it is preferable to place the unit under a cover which offers enough protection to prevent rain falling directly to the unit, or install the corresponding rain canopy (TPP accessory).

    Both in the case that the Kit feet is used, and if the unit is based on vibrators or supports made on site, it is essential that the heat exchanger’s support is guaranteed on the 6 existing support points and that all of them are in a same plane. In the case of not supporting the unit on the central supports it is possible that deformation occurs in the structure of the unit, making it impossible to disassemble the panels.
