Setting the Unit
The preferred way to lift and move the unit is to lift it with a forklift under the base.
In multiple unit installations, it is important to plan the position of each unit in advance. Sufficient
space for piping connections and future service/maintenance requirements must be taken into
consideration. All piping must include ample provisions for expansion
.
2.4 HEATING FLUID AND DOMESTIC HOT WATER (DHW) PIPING
The diameter of the heating fluid (hot boiler water) and DHW piping for all SmartPlate EV
models is 2.0 inches.
CAUTION!
Two pipe wrenches MUST be used when installing boiler water and DHW piping unions to
prevent pipe rotation and avoid leaks.
IMPORTANT
!
When SmartPlate EV Water Heaters are shipped from the factory, all four isolation ball valves
(see Figure 1.3) are open.
· CLOSE ALL VALVES DURING INSTALLATION
.
·
Do not open the valves until instructed to do so in Chapter 5 of this manual.
2.5 SmartPlate EV & BENCHMARK PLATINUM BOILERS
SmartPlate EV units come equipped with a linearized 3-Way Electronic Control Valve, described
in Section 1.4 and shown in Figure 2.5, below. All units are shipped with a factory-installed plug
in
the valve’s Port B.
Figure 2.5. SmartPlate EV 3-Way Plug
The way this valve is used depends on how many SmartPlate EV units are at the site:
•
Single SmartPlate EV installations
: Remove the factory-installed plug from port B by
inserting the hexagonal bar (provided in the loose parts kit) into the plug’s port and rotating
with a pipe wrench. Then, connect a pipe from this port to the upper return inlet on
Benchmark Series Platinum boilers. During operation, the SmartPlate EV unit determines
how much heating load is required to maintain setpoint temperature and provides the
required boiler water flow to the heat exchanger to maintain that temperature. Any
