HRZD Series 4.3 Filling of Circulating Fluid
4-3
4.3.2 Supply of circulating fluid
Remove the circulating fluid fill cap, and fill the circulating fluid until it reaches its
specified level.
The circulating fluid specified level is a range between “HIGH” and “LOW” in
Figure 4-1.
Be sure to tighten the cap until it clicks after fluid supply.
If the circulating fluid is supplied over the specified level, follow the procedure
provided in section 7.3.1 “Draining of circulating fluid out of tank” on page 7-4 to
drain excess fluid until it reaches the specified level.
[Tips]
Level between “HIGH” and “LOW” represent liquid level in normal running
condition. Immediately as you start filling up the product, the internal
transferring pump start pumping fluid from the Sub Tank into the Main Tank.
Thus the fluid level in the level gauge will start to drop.
During initial priming of the external piping, addition fluid is needed. See
section 8.1.1 “Product specification” on page 8-1 for Sub Tank and Main
Tank capacity.
Circulating fluid must be supplied to be in the range between “HIGH”
and “LOW”. Potential overflow of hot circulating fluid may occur due
to excessive volume.
Total fluid volume use to fill up the product including initial priming
should not exceed combined volume of Sub Tank and Main Tank.
If level is below the “LOW” mark, this product will trigger an alarm.
When supplying the circulating fluid, make sure that the fluid inside
the product has dropped to room temperature to prevent accidental
burns.
To prevent moisture, which is formed by condensation of a flowed air,
from finding its way into the tank, ensure the circulating fluid at room
temperature when supplying the fluid.
Be sure to tighten the cap until it clicks after fluid supply.
Potential circulating fluid vaporization or moisture intrusion due to
condensation of flowed air may occur if disregarded.
