(Fig. 5b) G provide a solid base (level concrete pad, concrete block, 6" × 1'4" (15 × 40 cm) beams or equal), a minimum of 6" (15 cm) above ground level to reduce humidity and protect the unit against possible water damage and decreased service life. (Figs. 5c and 5d) CAUTION A solid base must not cover the hole of the bottom plate. NO Hot air Exhaust fan Heat source Outdoor unit Obstacle above Air discharge Obstacle Fig. 5a Min.

Baffle Plate for the Outdoor Unit (CLM models only) Concrete or equal NOTE It is recommended to use baffle plates for models CLM1972, CLM2472 and CLM3172. The baffle plates are not normally required for the other models. When the outdoor unit is installed in a position exposed to strong wind (such as seasonal winds with low air temperature in winter), baffle plates must be installed on the outdoor unit. (Fig. 5f) This unit is designed so that the fan of the outdoor unit runs at low speed when the air conditioner is operated at low outdoor air temperatures. When the outdoor unit is exposed to strong wind, the system pressure drops because of the freeze protector. Install a pair of windbaffle plates at the front and back of the outdoor unit if it will be subject to strong wind during the winter.
