Safe Refrigerant Handling; Refrigerant Lines - Amana AVZC18 Installation & Service Reference

LECTRICAL OISE
The unit should be well grounded so that potential effects of elec-
trical noise from the inverter to surrounding equipment can be
minimized.
When selecting an installation location, keep sufficient distance
from the heat pump unit and wiring to radios, personal comput-
ers, stereos, etc., as shown in the following figure.

ANY LONGER THAN NECESSARY FOR INSTALLATION
Use only refrigerant grade (dehydrated and sealed) copper tubing
to connect the heat pump unit with the indoor unit. After cutting
the tubing, install plugs to keep refrigerant tubing clean and dry
prior to and during installation. Tubing should always be cut
square keeping ends round and free from burrs. Clean the tubing
to prevent contamination. The liquid line must be insulated if
more than 50 ft. of liquid line will pass through an area that may
reach temperatures of 30 °F or higher than ambient in cooling
mode and/or if the temperature inside the conditioned space may
reach a temperature lower than ambient in heating mode. Never
attach a liquid line to any uninsulated potion of the gas line.
.
Do NOT let refrigerant lines come in direct contact with plumbing,
.
ductwork, floor joists, wall studs, floors, and walls. When run-
ning refrigerant lines through a foundation or wall, openings
should allow for sound and vibration absorbing material to be
placed or installed between tubing and foundation. Any gap be-
tween foundation or wall and refrigerant lines should be filled
"
THE
with a pliable silicon-based caulk, RTV or a vibration damping
material. Avoid suspending refrigerant tubing from joists and studs
with rigid wire or straps that would come in contact with the
. B
Y
tubing. Use an insulated or suspension type hanger. Keep both
lines separate and always insulate the gas line.
Insulation is necessary to prevent condensation from forming
and dropping from the gas line. Armflex or satisfactory equiva-
lent with 3/8" min. wall thickness is recommended. In severe
. I
F
conditions (hot, high humidity areas) 1/2" insulation may be re-
quired. Insulation must be installed in a manner which protects
tubing and connections from damage and contamination.
