Initial Cooling Recommendations; Winterizing - Aquacal SQ120R Instruction Manual

2.11 Initial Cooling Recommendations

The following recommendations will reduce the amount of time required to cool a pool or cold plunge
application. If unsure of equipment cooling capability, review equipment data plate. See "Identifying
Model Specifications" on page 22.
1. Use the heat pump's "POOL/SPA" button to select the "POOL" group.
2. Set circulation pump time clock to 24 hours.
3. Confirm the mode has been set to "COOL" mode.
4. Set the desired temperature "COOL SETPOINT" for the water.
5. After the desired temperature has been reached, reset circulation pump time clock to normal time frame.

2.12 Winterizing

Failure to properly winterize the heat pump as needed may result in serious equipment damage.
DANGER
Deactivate power while routing wiring to control board.
l
Follow all National Electric Codes (NEC) and/or State and Local guidelines.
l
WARNING
Deactivate all electrical power to heat pump before performing hard freeze procedures.
l
NOTICE
Failure to winterize heat pump may result in serious equipment damage. Freeze damage is not covered under the
l
heat pump warranty.
While the plumbing connections are in the winterized condition (not fully tightened), it is imperative that water
l
not run through the heat pump. Loss of water through loose plumbing connections may result in damage to
circulation pump, pool and spa structures, and other equipment.
Light Freeze Conditions
A light freeze is when the ambient air temperature falls below 32 degrees Fahrenheit (0° C) for less than 8
hours. Typically during light freeze conditions circulating (or moving) water will not freeze. Temporarily
activate the filter pump for continuous operation during light freeze conditions.
Hard Freeze Conditions
A hard freeze is when the ambient air temperature falls below 32 degrees Fahrenheit (0° C) for more than
8 hours. In areas where this condition is prevalent and sustained, the heat pump MUST be winterized for
hard freeze conditions. Follow the correct procedure depending on the type of heat exchanger found in the
heat pump.
