5.6.2. DISCHARGE CONNECTIONS
Connect the discharges from each condensate
collection pan to the sewerage system either
directly or via the manifold.
• On each pan with discharge, fit a
drain trap of suitable height so as to
prevent air entering into the system by
depression, and stopping the correct
drainage of the water. A correct drain
trap also prevents the infiltration of bad
odours.
• The sizing and the construction of
the drain trap must comply with the
following formula: H >= P, where P,
expressed in mm w.c., is equal to the
pressure gain of the unit installed.
• The drain trap must be fitted with a bleeding cap at the lowest point, and must be made so
as to allow quick dismantling for more complete cleaning.
• The path of the condensate drain pipe must always slope down towards the outside.
• Check that the condensate drain pipe does not stress the discharge fitting on the unit.
5.7. ELECTRICAL CONNECTIONS
BEFORE STARTING ANY OPERATIONS, MAKE SURE THAT THE MAIN POWER LINE IS
DISCONNECTED.
• The electrical connections must be performed by specialist personnel.
• Check that the voltage and frequency shown on the unit’s rating plate match the mains
power supply.
CONNECT THE UNIT AND ALL ITS ACCESSORIES USING LES WITH A SUITABLE CROSS-
SECTION FOR THE POWER RATINGS AND IN COMPLIANCE WITH THE LOCAL STANDARDS IN
FORCE. THE SIZE OF THE CABLES MUST IN ANY CASE GUARANTEE A VOLTAGE DROP WHEN
STARTING OF LESS THAN 3% OF THE RATED VALUE.
• Never use adapters, multiple sockets and/or extensions in the main power supply to the unit.
THE INSTALLER MUST ENSURE THAT A POWER DISCONNECTING SWITCH AND ANY OTHER
DEVICES THAT PROTECT THE ELECTRICAL PARTS ARE INSTALLED AS NEAR AS POSSIBLE TO
THE UNIT.
• All the ventilating sections are fitted with door lock safety micro- switches; the connections
to the micro-switch must be made by the installer. The micro-switch disconnects power to
the motor when opening the inspection door.
CAUTION: WAIT 60 SECONDS BEFORE APPROACHING AND ENTERING THE VENTILATING
SECTION, SO AS TO ALLOW THE VENTILATING ASSEMBLY TO COME TO A COMPLETE STOP.
• Connect the unit to an effective earth wire.
6.0. CHECK BEFORE STARTING
Before starting, the air handling unit should undergo the following checks.
1. Check that the discharges are properly connected, ensuring the correct draining of the
condensate.
