Water Flow Rates; Adjusting Water Flow Using Δt (Delta-T) - Aquacal Tropicool TC500 Operation Manual

2.5 Water Flow Rates

Maintain water flow rates as indicated. Please note, these specifications relate to the chiller only. Code-
specified whole system turnover rates must be satisfied.

PLEASE NOTE -
If minimum flow rates are not met, chiller performance is reduced and performance will
suffer. Internal safety devices may deactivate the chiller with the following errors:
HP and HP5
l
or (if equipped) error codes of LP and LP5
l
Operate water filtration devices per manufacturer's specifications. Dirty filters can cause a reduction of water flow
l
to the chiller. An increase of 7-10 psi higher than the clean filter pressure typically reduces flow rates. This
requires the filter to be cleaned or back-washed.
Keep baskets free of debris. A large quantity of debris in the pump and skimmer baskets can reduce water flow.
l
Check for improper valve settings. A partially closed valve after the filter, or a full-open bypass around the
l
chiller, will cause insufficient water flow through the chiller.
The maximum static pressure (or operating pressure) is 50 pounds-per-square-inch (PSI). These specifications
l
relate to the chiller only.
Code-specified whole system turnover rates must be satisfied.

2.6 Adjusting Water Flow Using ΔT (Delta-T)
The Delta-T is the temperature difference between the water temperatures entering and leaving the chiller. The
equipment can be fine-tuned for maximum performance by balancing water flow rates to maintain an ideal
∆T.
Installed temperature ports are required to perform the following procedures.
l
This adjustment procedure must be completed with the unit in heating mode .
l
PLEASE NOTE -
The installation of temperature ports are required for all commercial applications.
l
The installation of temperature ports are strongly recommended for residential installations.
l
See "Temperature Port Kit" on page 19.

Failure to heed the following may result in damage to equipment.
Water flow exceeding maximum flow rates will negatively affect the total pool
l
filtration performance and may damage the chiller. This will not be covered under
equipment warranty.
