Installation
Responsibilities
Generally, the contractor must do
the following when installing an
RTAC unit:
[ ] Install the unit on a flat
foundation, level (within 1/4"
[6 mm] across the length and
width of the unit), and strong
enough to support unit loading.
[ ] Install the unit per the
instructions contained in the
Installation-Mechanical and
Installation-Electrical sections of
this manual.
[ ] Make electrical connections at
the CH.530.
[ ] Where specified, provide and
install valves in the water piping
upstream and downstream of the
evaporator water connections, to
isolate the evaporator for
maintenance and to balance and
trim the system.
[ ] Furnish and install a flow proving
device and/or auxiliary contacts
to prove chilled-water flow.
[ ] Furnish and install pressure
gauges in the inlet and outlet
piping of the evaporator.
[ ] Furnish and install a drain valve
to the bottom of the evaporator
water box.
[ ] Supply and install a vent cock to
the top of the evaporator water
box.
[ ] Furnish and install strainers
ahead of all pumps and
automatic modulating valves.
[ ] Provide and install field wiring.
[ ] 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.
[ ] Start the unit under the
supervision of a qualified service
technician.

Storage

Extended storage of the unit prior to
installation requires the following
precautionary measures:
1. Store the unit in a secure area.
2. At least every three months
(quarterly), check the pressure in
the refrigerant circuits to verify
that the refrigerant charge is
intact. If it is not, contact the
appropriate sales office.
3. Close the optional discharge and
liquid-line isolation valves.
