Installation
Responsibilities
Generally, the contractor must do the
following when installing an RTAA unit:
[ ] Install unit on a flat foundation, level
(within 1/4" [6.4 mm]), and strong
enough to support unit loading.
[ ] Install unit per the instructions
contained in the Installation
Mechanical and Installation
Electrical sections of this manual.
[ ] Install any optional sensors and
make electrical connections at the
UCM.
Note:
The standard leaving chilled
water sensor is factory installed in the
evaporator leaving water outlet.
[ ] Where specified, provide and install
valves in water piping upstream and
downstream of evaporator water
connections to isolate the
evaporator for maintenance, and to
balance/trim system.
[ ] If desired, supply and install flow
switches in the chilled water piping;
interlock each switch with proper
pump starter to ensure unit can only
operate if water flow is established.
Chilled water flow protection is
provided by the UCM without the
need for a chilled water flow switch.
A flow switch for chilled water is
strictly discretionary.
[ ] For Remote Evaporator units only,
furnish and install refrigerant piping,
refrigerant and oil, per the
instructions outlined in this manual.
[ ] Furnish and install pressure gauges
in inlet and outlet piping of the
evaporator.
[ ] Furnish and install a drain valve to
the bottom of the evaporator.
[ ] Supply and install a vent cock to the
top of the evaporator.
[ ] Where specified, furnish and install
strainers ahead of all pumps and
automatic modulating valves.
[ ] Provide and install field wiring.
[ ] Start unit under supervision of a
qualified service technician.
[ ] Install heat tape and insulate the
chilled water lines and any other
portions of the system, as required,
to prevent sweating under normal
operating conditions or freezing
during low ambient temperature
conditions.
