PLACE FOR FUTURE REFERENCE.
IMPROPER INSTALLATION
EQUIPMENT OR ACCESSORIES COULD RESULT IN
ELECTRIC SHOCK, SHORT-CIRCUIT, LEAKS, FIRE OR
OTHER DAMAGE TO THE EQUIPMENT. BE SURE ONLY
TO USE ACCESSORIES MADE BY ROTEX WHICH ARE
SPECIFICALLY DESIGNED FOR USE WITH THE
EQUIPMENT AND HAVE THEM INSTALLED BY A
PROFESSIONAL.
IF UNSURE OF INSTALLATION PROCEDURES OR USE,
ALWAYS CONTACT YOUR ROTEX DEALER FOR
ADVICE AND INFORMATION.
S

Outdoor unit for air to water heat pump
Page
OR ATTACHMENT OF
After completing installation, test the unit to check for installation
errors. Give the user adequate instructions concerning the use
and cleaning of the unit as included in the operation manual of
the indoor unit.
Warnings
Installation should be left to the dealer or another professional.
Improper installation may cause water leakage, electrical shock,
or fire.
Install the outdoor unit according to the instructions given in this
manual.
Incomplete installation may cause water leakage, electrical
shock, or fire.
Be sure to use the supplied or specified installation parts.
Use of other parts may cause the unit to vibrate loose, and may
cause water leakage, electrical shock, or fire.
Install the outdoor unit on a solid base that can support the
weight of the unit.
An inadequate base or incomplete installation may cause injury
in the event the unit falls off the base.
Electrical work must be carried out in accordance with the
installation manual and the national electrical wiring rules or
code of practice.
Insufficient capacity or incomplete electrical work may cause
electrical shock or fire.
Be sure to use a dedicated power circuit. Never use a power
circuit shared by another appliance.
For wiring, use a cable long enough to cover the entire distance
with no connection. Do not use an extension cord. Do not put
other loads on the power supply, use a dedicated power circuit.
Failure to do so may cause abnormal heat, electric shock, or fire.
Use the specified types of wires for electrical connections
between the indoor and outdoor unit.
Firmly clamp the interconnecting wires so that their terminals
receive no external stress. Incomplete connections or clamping
may cause terminal overheating or fire.
After connecting the interconnecting and supply wiring, be sure
to shape the cables so that they do not put undue force on the
electrical covers or panels.
Install covers over the wires. Incomplete cover installation may
cause terminal overheating, electrical shock, or fire.
If any refrigerant has leaked out during the installation
work, ventilate the room.
The refrigerant produces a toxic gas if exposed to
flames.
After all installation is complete, check to make sure
that no refrigerant is leaking.
The refrigerant produces a toxic gas if exposed to
flames.
When installing or relocating the system, be sure to keep the
refrigerant circuit free from substances other than the specified
refrigerant (R410A), such as air.
Any presence of air or other foreign substance in the refrigerant
circuit causes an abnormal pressure rise or rupture, resulting in
injury.
During pump down operation, stop the compressor before
removing the refrigerant piping.
If the compressor is still running and the stop valve is open
during pump-down, air will be sucked in when the refrigerant
piping is removed, causing abnormal pressure in the freezer
cycle which will lead to breakage and even to injury.
