tration (i.e. drywall dust) into cabinet and chassis coil
could result in equipment damage. Fumes could result
in premature corrosion (formicary corrosion) of the chas-
sis air-coil resulting in refrigeration system leaks.

STORAGE

Both cabinet and chassis units are designed for indoor
use only. Care must be taken to protect the unit from
environmental damage. Store the chassis in an environ-
ment with a temperature above (32
tamination the units should be stored indoors. For tem-
porary outdoor storage ensure:
•
Units should be placed in an area that will not be
exposed to any moisture. Units should be placed on
a dry and raised surface. Do not stack units.
•
Cover the units with a waterproof tarp.
•
Failure to keep the units dry could result in the inte-
rior insulation becoming wet and cause the growth
of mold.
•
Chassis units must be stored in the upright position
to keep oil in the compressor.
•
Chassis water openings and Riser ends should be
capped if being stored on site to prevent contamina-
tion from foreign objects and debris.
Chassis water circuit must not be filled
with any untreated or standing water prior
to full commissioning otherwise equipment
damage may occur.
Do not store cabinets on their side when chas-
sis units are inside. Chassis units should al-
ways be stored and transported in the upright
position otherwise damage to chassis may
occur.
The refrigeration system of these units con-
tains POE oil. PVC/CPVC piping is prone to
failure when in contact with POE oil. PVC/
CPVC piping should not be used for water
supply, return or condensate risers with any
heat pump products as this may result in failure
of the system and serious property damage.
Do not rest or lean the unit on the risers.
Do not use the risers or stub-outs to pick
up the unit. Only designated lift points
should be used when moving or lifting cab-
inets. Do not drop the risers.

FOR SHIPPED LOOSE RISER SHUT-OFF VALVES

Visually inspect riser stub-outs and shut-off valves for
debris or damage.

CABINET INSTALL

1) When cabinets are shipped with risers attached, place
cabinets in a horizontal position on the floor (do not rest
cabinet on the risers).
2) If required, install any field or factory supplied riser
extensions to the unit mounted risers.
OMEGA-VSHP.G-IOM-2205
Risers are designed to have slight adjustments
for riser system expansion and aligning the
stub-outs in the cabinet opening. When in-
stalling risers, do not let riser stubs bottom out
in the riser swage.
Risers are designed to allow for 1-1/2 inches of
movement due expansion and contraction. If
the total calculated riser expansion exceeds ±1
-1/2 inches the field must provide expansion
compensators.
Riser stub-outs should be located as centrally
as possible in the cabinet opening. Do not
allow stub-outs to rest or contact the sheet
metal opening.
Do not allow the risers to bottom out when
installing into the swage.
Follow industry standard soldering practices
when soldering shut-off valves to riser stub-
outs.
Ensure riser stub-out surface is cleaned of any
residue, soot or oils. Failure to adequately
clean soldering surfaces can result in water
leaks, property damage and physical injury.
When soldering shut-off valves to riser stub
outs, adequately protect cabinet, insulation
and any other equipment from exposure to
flames and heat.
