Overview
LG PRHR033A is a 3-port heat recovery unit (branch distribution unit) for LG Multi V heat-recovery VRF systems, running on R-410A. It routes refrigerant so that some zones heat while others cool on the same system, with one port per connected indoor unit. The R32 successor is PRHR033C.
37 lb net, 208-230/60/1 power. Multiple HR units can be cascaded on one system where zone counts exceed a single unit's ports.
Application notes
- Connects up to 3 indoor units; each port serves one indoor unit.
- Required only on heat-recovery (simultaneous heat/cool) systems — heat-pump systems connect indoor units directly.
- Mount in an accessible ceiling space with service clearance; the unit contains electronic expansion valves and requires power and communication wiring.
- Match the refrigerant family: R-410A systems use R-410A branch units.
Compatible Units
LG approves PRHR033A only in the combinations below (per the LG engineering manual and submittal). Mixing it with any other outdoor or indoor unit is not an AHRI-rated match. Ask the parts desk if your existing equipment isn't listed.

Common Questions
What does the LG PRHR033A pair with?
LG rates PRHR033A only with LG Multi V R-410A heat-recovery systems. Other combinations are not AHRI-matched and are not covered by the LG warranty.
What power does the PRHR033A need?
208-230V, 1-phase. Minimum circuit ampacity and maximum overcurrent protection are listed in the Specifications table above and on the LG submittal under Documentation; size the breaker and wire to those values and local code.
Is the submittal sheet and installation manual available for PRHR033A?
Yes — the LG submittal data sheet, engineering manual, installation manual and warranty document are all linked under Documentation on this page and can be downloaded without an account.
Is the stock number on this page real?
Yes — it's the live count from our own shelf, not an availability estimate. If it says 9, that's how many are physically here. When it hits zero, this page says so.
Is this a genuine LG unit, or aftermarket?
Genuine LG OEM equipment — not an aftermarket substitute.
I see this listed under a different name on other sites. Is it the same part?
Yes — manufacturers and distributors sometimes use different brand names or legacy labels for the same part number. Part number PRHR033A is identical across all name variations.
What's the warranty on this part?
Warranty terms vary by manufacturer. Contact us with your order number for details specific to this part.
How fast does this ship?
In-stock items ship the same business day on orders placed before 1pm ET, Monday–Friday. Standard ground delivers to most of the continental US in 2–5 business days.
Does everything ship UPS or FedEx Ground?
Most orders ship UPS or FedEx Ground. A small number of large or heavy parts across the catalog ship by truck freight instead — that's still free, and we reach out to arrange a delivery window before those orders leave the warehouse.
