Installation Precautions - Toshiba HWT-601XWHM3W-E Installation Manual

Hydro Unit
• Install the refrigerant pipe securely during installation and before
operation.
If the compressor is operated with no pipe work connected and
valves open the compressor will suck air which would result in
over pressurization of the system which may result in bursting or
injury.
Observe the same precautions for refrigerant recovery work
(pump back procedure to Outdoor Unit) and do not disconnect
pipe work until refrigerant is recovered and valves closed.
WARNING

Installation precautions

• Ask an authorized dealer or qualified installation professional to
install/maintain the Air to Water Heat Pump System.
Inappropriate installation may result in water leaks, electric shock
or fire.
• Electrical work must be performed by a qualified electrician in
accordance with the installation manual.
An inappropriate power supply capacity or installation may result
in fire.
• When completing any electrical works to the system ensure that
all Local, National and International regulations are satisfied.
Inappropriate grounding may result in electric shock.
• Ensure all electrical cables, used for the Hydro Unit installation,
comply with all Local and National regulations. Check all electrical
terminations are secure and tight.
• Earth wire connections.
• Install an earth leakage breaker without fail.
Incomplete grounding can cause electric shock.
Do not earth wires to gas pipes, water pipes, lightning rods or
telephone cable earth wires.
• This unit must be connected to the main power supply using a
circuit breaker or switch with a contact separation of at least 3 mm.
7-EN
• Be sure to turn off all main power supply switches or the circuit
breaker before starting any electrical work.
Ensure all power switches are off, failure to do so can cause
electric shock.
Use an exclusive power circuit for the Air to Water Heat Pump
system using the rated voltage.
• Ensure correct connection of interconnecting wire between
Outdoor Unit and Hydro Unit.
Incorrect connection of the interconnecting cable may result in the
damage of electrical parts.
• Under no circumstances must the power cable be extended.
Poor connections, where the cables are joined, may give rise to
smoking and/or fire.
• Ensure refrigeration system remains sealed to external gases and
air.
Should air or other gases contaminate the refrigeration circuit,
high system pressures could result in burst pipes and injuries.
• Do not modify or bypass any of safety guards or switches in this
system.
• After unpacking the Outdoor Unit, examine the unit carefully for
any possible damage.
• Do not install in any place that might increase the vibration of the
unit.
• To avoid personal injury (with sharp edges), be careful when
handling the Hydro Unit.
• Perform installation work properly in accordance with the
installation manual.
Inappropriate installation may result in water leaks, electric shock
or fire.
• Tighten all flare nuts with a torque wrench in the specified manner.
Excessive tightening of the flare nut may result in cracking of the
pipe work or flare nut which may result in a refrigerant leakage.
