GS4-45HPC Freeze Protection
Product Information:
The Freeze Protection GS4-45HPC is a product designed to prevent
freezing of water pipes, particularly when installed outdoors. It
features a unit freeze protection control program and can be used
with heat tape on the pipe work for added freeze protection. In the
event of a power outage, the unit is equipped with freeze
protection functionality. Additionally, the unit and piping can be
drained manually for further freeze protection.
Product Usage Instructions:
- Minimal Water Piping Outdoors: Install the
Freeze Protection GS4-45HPC in areas where water piping is exposed
to low temperatures outdoors. - Unit Freeze Protection Control Program: Ensure
that the unit’s freeze protection control program is activated.
Refer to the user manual for instructions on how to enable this
feature. - Heat Tape on Pipe Work: For enhanced freeze
protection, consider using heat tape on the pipe work. Follow the
manufacturer’s instructions for proper installation and usage of
the heat tape. - Power Outage: In case of a power outage, the
Freeze Protection GS4-45HPC will automatically activate its freeze
protection functionality. This helps to prevent freezing of the
water pipes. Once power is restored, the unit will resume normal
operation. - Manual Drain: To further protect against
freezing, you can manually drain the unit and piping. Refer to the
user manual for detailed instructions on how to perform a manual
drain.
It is important to regularly check the user manual for any
specific guidelines or recommendations regarding the Freeze
Protection GS4-45HPC’s usage and maintenance.
Freeze Protection GS4-45HPC
· System design will have the Outdoor unit & Piping filled with Water so it is important for the system to be capable to handle installations in cold weather locations and how the unit will operate to reduce this cold weather effect
· Interestingly it also gets cold in Japan (Sapporo, design temperature is 15°F). Nothing is done to the system to worry about cold weather, EVEN the tank is outside
Freeze Protection
Minimal Water Piping Outdoors
· Plan your job site and unit(s) location to penetrate into the building adjacent to the Heat Pump(s)
· Use ¾” minimum thick Closed Cell insulation on the external piping Larger thickness of insulation can be used for colder ambient locations to provide more insulation
· Tape joints and ensure that none of the system is piping is exposed
Freeze Protection
Unit Freeze Protection Control Program
· System continually monitors Inlet & Outlet Water Temperatures plus Outdoor Ambient Temperature
· Unit will operate the unit Pump and Compressor to ensure quick heat up of the Inlet and Outlet water before cycling off
Freeze Protection
Heat tape on the pipe work
¾”
· Self regulating 5 to 8W Heat Trace used to heat both Cold & Hot Piping
¾”
· FG2-6L is a 6ft long Heat Trace with a 3ft lead cord on it to allow the FG2-6L to be directly connected to the 208/230V L1 & L2 Incoming power terminals directly without needing any extra wiring
Freeze Protection
Heat tape on the pipe work · Install the FG2-6L by wrapping
tightly under the insulation on both Hot & Cold Piping to unit The 6ft length should provide both pipes with Heat
· Start the wrap around process at the Hot Water Outlet connection then around the external piping and cross over to the Cold Water piping in the building and complete all of the FG2-6L wrap process at the Cold Water Inlet Connection at the GS4
Freeze Protection
Power Outage
· Use the FPVKT-SMTW Valve kit to allow water to drain from the Cold & Hot piping to the unit
· 2 x FPV Valves & 2 x Tees for easy installation are provided with the Kit
· FPV Valves are installed on both Cold & Hot Piping to the GS4
Freeze Protection
Power Outage
· FPVKT will open on BOTH or EITHER of the Cold & Hot piping to start the drain process if the Water temp falls below 34°F
· As Valve(s) open the Water Pressure in the piping will allow 34°F Water to be drained out of piping drawing warmer water from inside the Tank or building into the piping to replace the Cold Water being drained
· Valves will close when the Water drained from the system rises above 39°F in the piping and GS4 unit
Manual Drain
Unit and piping can also be drained manually
· Close Isolation Valves installed on the piping to the GS4 unit from the Storage tank
· Open the Air bleed screws on the GS4 Cold Water Inlet Connector and Hot Water Outlet Connector to manually drain down the System
· Also drain water using the Air Bleed on the Water Pump underneath the unit
· After power outage open closed Isolation valves, fill and bleed the system then restart the GS4
