3. Introduction
3.1. General information
This installation manual concerns the VRV IV, full inverter driven,
heat pump system for replacement purposes. Depending on the
situation, the existing refrigerant piping of a previous installation or in
some cases even indoor units can be reused.
Model line up:
RXYQQ8~20=single unit model.
RXYQQ22~42=multi unit model (consisting of 2 or 3 RXYQQ*
modules).
These units are intended for outdoor installation and aimed for heat
pump applications including air to air applications.
These units have (in single use) heating capacities ranging from 25 to
63 kW and cooling capacities rating from 22.4 to 56 kW. In multi
combination the heating capacity can go up till 132 kW and in cooling
till 118 kW.
Electric current.
Danger of burning and scalding.
DANGER: ELECTRICAL SHOCK
Switch off all power supply before removing the electrical
component box service panel or before making any
connections or touching electrical parts.
Do not touch any switch with wet fingers. Touching a
switch with wet fingers can cause electrical shock. Before
touching electrical parts, turn off all applicable power
supply.
To avoid electric shock, be sure to disconnect the power
supply 1 minute or more before servicing the electrical
parts. Even after 1 minute, always measure the voltage at
the terminals of the main terminal, main circuit capacitors
or electrical parts and, before touching, be sure that those
voltages are 50 V DC or less.
When service panels are removed, live parts can easily be
touched by accident. Never leave the unit unattended
during installation or servicing when the service panel is
removed.
DANGER: DO NOT TOUCH PIPING AND INTERNAL
PARTS
Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.
Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if you
must touch them, be sure to wear protective gloves.
