Heat Controller, Inc. WATER-TO-WATER (HWW) SERIES Installation & Operation
General Information
Inspection
Upon receipt of the equipment, carefully check the shipment
against the bill of lading. Make sure all units have been re-
ceived. Inspect the carton or crating of each unit, and inspect
each unit for damage. Assure the carrier makes proper nota-
tion of any shortages or damage on all copies of the freight bill
and completes a common carrier inspection report. Concealed
damage not discovered during unloading must be reported
to the carrier within 15 days of receipt of shipment. If not filed
within 15 days, the freight company can deny the claim without
recourse. Note: It is the responsibility of the purchaser to
file all necessary claims with the carrier.
Storage
Equipment should be stored in its original packaging in a
clean, dry area. Store units in an upright position at all times.
The stack limit for HWW36, 060 and 120 is three.
Unit Protection
Cover units on the job site with either shipping packaging,
vinyl film, or an equivalent protective covering. Cap the open
ends of pipes stored on the job site. In areas where painting,
plastering, and/or spraying has not been completed, all due
precautions must be taken to avoid physical damage to the
units and contamination by foreign material. Physical damage
and contamination may prevent proper start-up and may result
in costly equipment clean-up.
Examine all pipes, fittings, and valves before installing any of
the system components. Remove any dirt or trash found in or
on these components.
Pre-Installation
Installation, Operation, and Maintenance instructions are
provided with each unit. The installation site chosen should
include adequate service clearance around the unit. Before
unit start-up, read all manuals and become familiar with the
unit and its operation. Thoroughly check the system before
operation.
Prepare units for installation as follows:
1. Compare the electrical data on the unit nameplate with
ordering and shipping information to verify that the cor-
rect unit has been shipped.
2. Keep the cabinet covered with the shipping packaging
until installation is complete and all plastering, painting,
etc. is finished.
3. Verify refrigerant tubing is free of kinks or dents and that
it does not touch other unit components.
4. Inspect all electrical connections. Connections must be
clean and tight at the terminals.
� CAUTION! �
CAUTION! All three phase scroll compressors must
have direction of rotation verified at start-up. Verification
is achieved by checking compressor Amp draw. Amp
draw will be substantially lower compared to nameplate
values. Additionally, reverse rotation results in an ele-
vated sound level compared to correct rotation. Reverse
rotation will result in compressor internal overload trip
within several minutes. Verify compressor type before
proceeding.
� CAUTION! �
CAUTION! DO NOT store or install units in corrosive
environments or in locations subject to temperature or
humidity extremes (e.g., attics, garages, rooftops, etc.).
Corrosive conditions and high temperature or humid-
ity can significantly reduce performance, reliability, and
service life. Always move and store units in an upright
position. Tilting units on their sides may cause equip-
ment damage.
� CAUTION! �
CAUTION! CUT HAZARD - Failure to follow this caution
may result in personal injury. Sheet metal parts may
have sharp edges or burrs. Use care and wear appropri-
ate protective clothing, safety glasses and gloves when
handling parts and servicing heat pumps.
NOTICE! Failure to remove shipping brackets from
spring-mounted compressors will cause excessive
noise, and could cause component failure due to
added vibration.
