Winterizing - Aquacal TropiCal T035 Operation Manual

2.8 Winterizing

Failure to properly winterize the heat pump as needed may result in serious equipment damage.
DANGER
RISK OF ELECTRICAL SHOCK FROM ENERGY STORED IN CAPACITORS - MODELS EQUIPPED
l
WITH VARIABLE FREQUENCY COMPRESSOR DRIVES STORE ELECTRICITY EVEN AFTER THE
POWER HAS BEEN DEACTIVATED AT THE POWER BREAKER. Wait for 2 minutes after the shut down
of equipment before servicing.
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 not
l
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.
Confirm Exchanger Type:
1. Deactivate all electrical power to heat pump.
2. Deactivate the filter pump.
3. Remove the front access panel.
4. Identify heat exchanger from the illustration(s) in this section.
5. Reinstall front access panel. Then follow the procedure for the appropriate
heat exchanger.
