Notes for Refrigerant Piping Page 1 of 2 Rev. 11-11-11
Notes for VRV Refrigerant Piping
1.
All joints shall be brazed except at the indoor units which shall be flared
2.
All piping shall be installed in accordance with the mechanical design. Any deviation shall be
submitted for prior approval to the mechanical engineer prior to installation. Selected copper
tube must be of suitable wall thickness for higher operation pressures.
3.
Flaring: Flared tube ends should have a smooth, even round flare of sufficient length to fully
engage the mating surface of the flare nut, without protruding into the threads. Use only PVEor POE refrigeration oil when making flares. Dedicated flare block and tool is recommended.
Only use synthetic oil on the flare tool.
4.
All piping exterior to building, shall be a minimum of type L, ACR rated straight pipe for R-
410A or as specified. All piping on the building interior shall be L, ACR rated rolled soft
copper or line set for R-410A or as specified, piping (after annealing) shall have sufficient wall
thickness for a continuous operating pressure of 600 PSI per ASME B 31.5-2010.
5.
Dry Nitrogen: Dry nitrogen must be used during all brazing (pressure regulated to 3 PSI) to
prevent copper plate or oxidation formation.
6.
Pressure testing: Tighten down stop valves before any pressure testing to prevent nitrogen
from leaking back through condenser and contaminating refrigerant.Pressure testing shall be done in three (3) steps.
Step 1 Leak check 3 minutes at 150 PSI
Step 2 Leak check after 5 minutes at 325 PSI
Step 3 Leak check after 24 hours at 550 PSI (450 psi for systems with vertical Air Handlers)
Always check flare nuts for leaks using bubble solution. Be sure to use a recommended product.
Do not use a watered down fairy liquid solution.
7.
Leak testing and evacuation shall be done in accordance with the US EPA Green Chill Best
Practices Guideline Ensuring Leak-Tight Installation of Commercial Refrigerant Equipment.
8.
Evacuation procedures: Evacuation procedures shall be performed as follows:
A.
Evacuate the system to 4000 microns. Break the vacuum with dry nitrogen to a pressure of2-3 PSI and hold for 15 minutes.
B.
Evacuate system to 1500 microns and maintain for 20 minutes. Break the vacuum with dry
nitrogen to a pressure of 2-3 PSI and hold for 15 minutes.
C.
Evacuate system to below 500 microns and hold for 60 minutes.
D.
Evacuate system to below 300 microns and hold for 24 hours.
Vacuum pump check valve should be used to prevent mineral oil from being drawn into the
system. These procedures must be adhered to, documented and included in the contractors
price.
9.
Refrigerant charging: Weigh in additional refrigerant with digital scales. Calculate charge based
on total line length plus lb/ft of diameter. Check with each unit model for correct multiplier.
After the amount of refrigerant to be added is determined write it down on the label on the
back side of the front cover. After the vacuum/drying is complete, charge the additional
refrigerant in its liquid state through the liquid stop valve service port.
Make sure to use installation tools you exclusively use on R410A installations to withstand the
pressure and to prevent foreign material from mixing into the system.

Notes for Refrigerant Piping Page 2 of 2 Rev. 11-11-11
Notes for VRV Refrigerant Piping Continued
10.
All refrigerant piping and Refnets exterior to the building shall have aluminum jacket covering
the insulation in accordance with the following specifications.
Equivalent to Pabco-childers metals aluminum roll jacketing, .016 thick, complying with
3105/3003 standard alloys, stucco empossed finish with polysurlyn moisture retarder. Provide
" aluminum band clamp every 10 to 12.
11.
Insulation techniques: All pipe work must be insulated along its full run using code compliant
(25/50 rated), Armaflex model UT/Solaflex, " thick, high temperature and UV resistant
closed cell insulation.
Insulation of pipes should be done after performing work required by note 8 (air tight test and
vacuum drying). Insulate the liquid piping, the HP/LP gas piping, the gas piping, the equalizer
pipe (between the outside units for the outside multisystem) and these pipe connections.
Insulation shall withstand temperatures of 248 degrees F or more for the HP/LP gas piping, the
equalizer pipe and gas piping.
Cover flare nuts on the fan coils using the insulation provided or condensation will occur causing
leaks.
12.
Un-insulated joints will condense moisture around the fittings. Line components: Do not install
driers, oil traps, sight glasses or any other line component in the pipe work as this will affect the
performance and warranty.
13.
VRV systems shall be installed in accordance with ASHRAE 15.
14.
VRV systems shall be installed by a manufacturer certified and trained contracting company and
shall have documentation of VRV installation & commissioning training. Field Superintendentshall have VRV training and certification.
Certification, training and commissioning documentation to be furnished with the contractors
bid and/or notice to proceed.
VRV supplier shall include a special VRV tool kit allowance for the installing contractor consisting
of:
A.
Standard R-410A gauge kit with multiple tools
B.
Torque wrench set
C.
R-410A flare tool
D.
R-410A plastic flare size gauge
If installing contractor does not currently have these special tools.
15.
In applications where the Refnet kits are installed in an environment requiring fire-rated
material to be used, it is necessary for the installer to obtain from a third part supplier and to
utilize, for installation, fire-rated materials that meet all applicable building codes and other
requirements. The factory supplied insulation should be discarded in a manner meeting all
applicable law.

Summary of the Commissioning Request Procedure
The following outlines the procedure for smooth processing of the installing contractors
commissioning request:
1. Contractor completes the Request for Supervised Commissioning form
2. Contractor submits the Request to Hoffman & Hoffman, Inc.
3. Supervising personnel will contact the installing contractor to schedule the
commissioning.
4. Contractor completes the Pre-Commissioning checklist and submits to the Hoffman &
Hoffman Coordinator a minimum of 48 hours prior to the scheduled commissioning.
5. The contractor, salesperson and supervising personnel meet at the jobsite on the
scheduled date to perform the Supervised Commissioning session.6. By completing and signing the Pre-Commissioning checklist, the contractor confirms and
represents that the job is ready for commissioning. If upon arrival on the scheduled day
for the commissioning it is found that any portion of the job is not ready for
commissioning, the contractor shall be subject to additional fees.
7. The installing contractor is responsible for arranging access to the equipment on the day
of the commissioning. This includes notifying the necessary parties at the site to insure
access to all components of the system. The contractor must provide any ladders, lifts,
keys, or other devices necessary to access the equipment.
This supervision of commissioning is to offer supervision of the contractor performing
the commissioning onsite. The installing contractor must have adequate personnel
onsite at the time of the assisted commissioning. The installing contractor is responsible
for providing all service tools, test equipment, refrigerant, and other supplies necessary
to conduct the commissioning.
