Rinnai Circ-Logic RL94i User Manual

7 Rinnai Circ-Logic™ with Grundfos Kit
Pump Installaon
A licensed professional must install the GTK15 kit.
The installer should have skills such as
 connecng gas lines, water lines, valves, and
electricity
 knowledge of applicable naonal, state, and local
codes
If you lack these skills, contact a licensed professional.
The pump supplied with your GTK15 kit is meant for
indoor installaons only. It is designed to circulate
water from 36°F to 150°F up to a maximum pressure of
145 PSI.
The proper operang voltage and other electrical
informaon can be found on the nameplate aached
to the top of the motor.
Posion of terminal box:
Proper installaon of the pump will have the terminal
box located to one side of the pump or the other, with
the conduit entry down. See Figure 3A.
The arrows on the side or boom of the pump housing
indicate direcon of ow through the pump.
GRUNDFOS circulators can be installed in both vercal
and horizontal lines. The pump must be installed with
the motor sha posioned horizontally. Under no
circumstances should the pump be installed with the
sha vercal or where the sha falls below the
horizontal plane. See Figure 3B.
It is recommended that isolaon valves be installed on
each side of the pump. If possible, do not install
elbows, branch tees, and similar ngs just before or
aer the pump. Provide support to the pump or
adjacent plumbing to reduce thermal and mechanical
stress on the pump.
Installaon
1. Thoroughly clean and ush the system prior to
pump installaon.
2. Do not install the pump at the lowest point of the
system where dirt and sediment naturally collect.
3. Install an air vent at the high point(s) of the system
to remove accumulated air.
4. Ensure that water does not enter the terminal box
during the installaon process.
5. Install the pump as shown on the system drawings;
the sucon side of the pump should be ooded
with water.
6. DO NOT START THE PUMP UNTIL THE SYSTEM HAS
BEEN FILLED AND CHECKED FOR LEAKS OR OTHER
POSSIBLE COMPONENT FAILURES.
