INSTALLATION
INSTALLATION LOCATION
Consult and respect the rules and local regulations which regulate the installation of air conditioning systems.
Choose a site without dust and debris.
Respect the appropriate service area for the equipment wich will be installed.
Verify that the ground or structure on which the unit will be installed is able to support its weight in operation.
Fit shock absorbers throughout the installation to prevent the transmission of noise and vibration.
Check that the direction of the sound level is not going to disturb anyone.
UNIT SETTLEMENT
Be sure unit is correctly leveled.
The bed frame should have sufficient strength to support unit weight.
Be sure that after settlement the unit drain is working properly.
WATER DRAIN
The indoor drain (of condensate water) has connection 3/4’’ MPT.
Condensate evacuation line diameter should be equal or larger than unit drain
connection depending on the line length and general building configuration.
The condensate line should be pitched a minimum 2% for proper water evacuation.
When drain line is exposed to air temperatures below 0 grades is necessary to provide
thermal insulation or electrical heating wire to avoid water freezing and tube damage.
It is convenient to install the trap with proper dimensions.
SECURITY ELEMENTS
The installation of the following safety elements, when
NOT
incorporated as standard in the unit or in the hydronic kit, is
MANDATORY
.
Failure to do so will result in
LOSS OF WARRANTY.
Water Filter:
At the entrance of the unit to protect the exchanger or other critical components against obstructions and / or
entanglements.
Flow Switch or Differential Pressure Control:
Protection of the water exchanger against breakage due to insufficient water flow,
which can lead to total disabling of the equipment.
ELECTRICAL CONNECTIONS
Unit current supply should be within 10% of Volts indicated on the unit
nameplate.
Damage caused by the start-up of the unit in an incorrect voltage line is not
covered by the Hitecsa guarantee.
When making electrical connections always use the unit wiring diagram.
Be sure that the compressor crankcase heater can be energized before unit
start.
Do not operate at any different current from that is shown on the unit’s
nameplate.
The installer has to install the line protection elements according to the local
laws.
The interconnecting wires have to be in the protection tube or inside the
groove channel.
Before starting any type of operations put in position off
main power switch.
