Design & installation Guide For McQuay MDS Multi System
● Connecting the hose to the drainage pipe of outdoor unit;
● Pour the water through the water inlet port and check if there is any water leakage;
● When the test is finished, connect the other side of the hose to the drainage pipe of the indoor
unit.
● The unit must be installed horizontally in order to prevent the water leakage and
condensated water from generating.
■ Installation of front panel
● There is only one direction to install the front panel, which depends on the position of
indicator light and motor wiring;
● The installation paper must be taken away before the installation of front panel;
● Open the two bolts of the front grille, then take out the filter and front grille;
● Tighten the front frame to the indoor unit with four bolts and flat gasket and screw it to a
tight extend, which can prevent the air leakage;
● Connecting the indicator light and motor wiring to the indoor unit (wire controlling type
without indicator light connecting wire).
【Note】Fix the front frame to avoid cooling leakage, which may cause water to coagulate and generate water drop.
【Note】This type of units adopts drainage pump to drain condensate water, and installing the unit horizontally is
to avoid water leakage and coagulation.
