Hot Water Generator Module Refrigeration Installation
For Outdoor Compressor Section Only
Location/Mounting
The HWG module should be mounted indoors and as close
to the heat pump outdoor section as possible, in order to
minimize the length of refrigerant run. It is recommended that
the HWG module be mounted above the system compressor
in order to promote proper oil movement and drain-down.
This means that the HWG module can be wall mounted
in any orientation except for stubs up. Mounting should be
accomplished by fastening the HWG module cabinet to the
wall or other selected vertical surface. Mounting holes are
provided at the rear of the unit. Any fastener suitable for sup-
porting a 12 pound [5.4] vertical load is acceptable.
SPECIAL NOTE: The selected mounting location and
orientation must allow the circulator pump to be positioned
with the motor shaft horizontal. DO NOT install the Heat
Recovery Unit flat on its back.
Refrigerant Line Installation
Before starting the installation into the refrigerant circuit,
inspect and note the condition and performance of the heat
pump. Disconnect power to the heat pump outdoor unit. Any
system deficiencies must be corrected prior to installing the
HWG module. Addition of the HWG will not correct system
problems. Record the suction and discharge pressures
and compressor amperage draw. These may be used for
comparison with system operation after the refrigerant line
installation is complete.
Install the Add-On HWG Kit
Locate the HWG as close to the water heater as possible.
Install the lineset to the desuperheater valves in the out-
door compressor section and the refrigerant line connec-
tions on the HWG. Maximum length should be 30 feet one
way. Evacuate the lineset to 500 microns through the hot
gas valves in the outdoor unit. Open the HWG valves in the
compressor section up fully (and close the desuperheater
bypass valve). See Figures 3a through 3d. Check the lineset
for leaks. Verify that lineset tubing is completely insulated
with a minimum 1/2” thick closed cell and painted to prevent
deterioration of the insulation due to ultra violet light and
weather. Make the connections with high temperature solder
or brazing rod. The recommended line size is dependent on
the one way distance between the Hot Water Generator and
the compressor; and the size of the system. Use Figure 4 as
a guideline.

WARNING! The HWG module is an appliance that
operates in conjunction with the heat pump system, the
hot water system and the electrical system. Installation
should only be performed by skilled technicians with
appropriate training and experience. The installation must
be in compliance with local codes and ordinances. Local
plumbing and electrical building codes take precedence
over instructions contained herein. The Manufacturer
accepts no liability for equipment damaged and/or personal
injury arising from improper installation of the HWG module.
CAUTION! The HWG module must be installed in an area
that is not subject to freezing temperatures.
NOTICE! Make sure the compressor discharge line is
connected to the “Hot Gas In” stub on the Hot Water
Generator.
CAUTION! Locate Refrigerant lines to avoid accidental
damage by lawnmowers or children.
