Below is a quick install guide for cold weather applications. 0 Installation location Be aware of the prevailing wind direction in winter and install the outdoor unit where it is sheltered from the wind when possible. When not possible, it is recommended to use an accessory wind baffle _ Units are easily affected by wind and unit may not be able to run at full capacity Measures for snow M&P Series Measures for drainage of water ■Case 1: Unit installed near walkway Do not install the unit near a walkway as the drainage water can freeze causing a slip hazard Drainage water splashes on pedestrians.

Outdoor units equipped with a heater for cold regions are those with an "H" in the model name. For the cold -climate zone, use of a unit with a heater is strongly recommended. Even for the moderate -climate zone use of a unit with a heater is recommended for regions subject to high humidity in winter.
