Safety precautions
The unit must be mounted to a rigid and stable structure. The unit must be suspended using threaded rods. Before starting mounting
check that the mounting structure has sufficient loading capacity for the unit weight. Otherwise reinforce the mounting location with
beams or similar elements. If the threaded rods used for the unit mounting are too short, the unit can generate abnormal noise resulting
from resonance with the ceiling. Use threaded rods of sufficient length to prevent resonance.
If the abnormal noise is generated at the spiral air duct joint, replace the spiral air duct with a flexible one to prevent resonance.
Flexible anti-vibration connectors are another alternative for dealing with resonance.
CONDENSATE DRAINAGE
The drain pan is equipped with two drain pipes for condensate removal outside the unit. Connect the drain pipe, the U-trap (not included
in the standard delivery set) and the sewerage system with metal, plastic or rubber pipes. While laying the connection pipes provide the
slope of minimum 3° downwards. Fill the system with water prior to connecting it to power supply! The U-trap must always be filled
with water. Provide free drainage for the condensed water, otherwise it is accumulated inside the unit that may cause the equipment
damage and condensate outflow to the room. The condensate drainage system is designed for normal operation in premises with air
temperatures above 0 °C! If the expected ambient air temperatures are below 0 °C, the condensate drainage system must be equipped
with heat insulation and preheating facilities.
